Without even a touch of the steering wheel, the electric car reverses autonomously into the recharging station
I won’t be plugging it in though, instead, the battery will be swapped for a fresh one, at this facility in Norway belonging to Chinese electric carmaker, Nio.
The technology is already widespread in China, but the new Power Swap Station, just south of Oslo, is Europe’s first.
This is what I’ve been saying for years would be a better strategy for electric vehicles. Instead of charging them (the time needed to charge is their single biggest weakness compared
to fuelled vehicles) we should be doing battery swaps. A decade or two ago I spoke hopefully for some kind of standardised connector and removal interface, probably below the vehicle,
through which battery cells could be swapped-out by robots operating in a pit. Recovered batteries could be recharged and reconditioned by the robots at their own pace. People could
still charge their cars in a plug-in manner at their homes or elsewhere.
You’d pay for the difference in charge between the old and replacement battery, plus a service charge for being part of the battery-swap network, and you’d be set. Car manufacturers
could standardise on battery designs, much like the shipping industry long-ago standardised on container dimensions and whatnot, to take advantage of compatibility with the wider
Rather than having different sizes of battery, vehicles could be differentiated by the number of serial battery units installed. A lorry might need four or five units; a large car two;
a small car one, etc. If the interface is standardised then all the robots need to be able to do is install and remove them, however many there are.
This is far from an unprecedented concept: the centuries-old idea of stagecoaches (and, later, mail coaches) used the same idea, but with the horses being changed at coaching
inns rather. Did you know that the “stage” in stagecoach refers to the fact that their journey would be broken into stages by these quick stops?
Anyway: I dismayed a little when I saw every EV manufacturer come up with their own battery standards, co=operating only as far as the
plug-in charging interfaces (and then, only gradually and not completely!). But I’m given fresh hope by this discovery that China’s trying to make it work, and Nio‘s movement in Norway is exciting too. Maybe we’ll get there someday.
For lunch today I taste-tested five different plant-based vegan “cheeses” from Honestly Tasty. Let’s see if they’re any good.
This blog post is available as a video (here or on YouTube), for those who like that sort of thing. The content’s slightly different, but you
do get to see my face when I eat the one that doesn’t agree with me.
I’ve been vegetarian or mostly-vegetarian to some degree or another for a little over ten years (for
those who have trouble keeping up: I currently eat meat only on weekends, and not including beef or lamb), principally for the environmental benefits of a reduced-meat lifestyle. But if
I’m really committed to reducing the environmental impact of my diet, the next “big” thing I still consume is dairy products.
My milk consumption is very low nowadays, but – like many people who might aspire towards dropping dairy – it’s quitting cheese that poses the biggest challenge. I’m not even the
biggest fan of cheese, and I don’t know how I’d do without it: there’s just, it seems, no satisfactory substitute.
It’s possible, though, that my thinking on this is outdated. Especially in recent years, we’re getting better and better at making convincing (or, at least, tasty!) plant-based
substitutes to animal based foods. And so, inspired by a conversation with some friends, I thought I’d try a handful of new-generation plant-based cheeses and see how I got on. I
ordered a variety pack from Honestly Tasty (who’ll give you 20% off your first order if you subscribe your favourite throwaway email address to
their newsletter) and gave it a go.
It’s supposed to taste like Brie, I guess, but it’s not convincing. The texture of the rind is surprisingly good, but the inside is somewhat homogeneous and flat. They’ve tried to use
mustard powder to provide Brie’s pepperiness and acetic acid for its subtle sourness, but it feels like there might be too much of the former (or perhaps I’m just a little oversensitive
to mustard) and too little of the latter. It’s okay, but I wouldn’t buy it again.
This was surprisingly flavoursome and really quite enjoyable. It spreads with about the consistency of pâté and has a sharp tang that really stands out. You wouldn’t mistake it for
cheese, but you might mistake it for a cheese spread: there’s a real “cheddary” flavour buried in there.
This is supposed to be modelled after Gorgonzola, and it might as well be because I don’t like either it or the cheese it’s based on. I might loathe Blue slightly less than
most blue cheeses, but that doesn’t mean I’d willingly subject myself to this again in a hurry. It’s matured with real Penicillium Roqueforti, apparently, along with seaweed, and it
tastes like both of these things are true. So yeah: I hated this one, but you shouldn’t take that as a condemnation of its quality as a cheese substitute because I’d still rather eat it
than the cheese that it’s based on. Try for yourself, I guess.
This was probably my favourite of the bunch. It’s reminiscent of garlic & herb Boursin, and feels like somebody in the
kitchen where they cooked it up said to themselves, “how about we do the Ched Spread, but with less onion and a whole load of herbs mixed-through”. It seems that it must be easier to
make convincingly-cheesy soft cheeses than hard cheeses, but I’m not complaining: this would be great on toast.
If you’d served me this and told me it was a baked Camembert… I wouldn’t be fooled. But I wouldn’t be disappointed either. It moves a lot like Camembert and it tastes… somewhat like it.
But whether or not that’s “enough” for you, it’s perfectly delicious and I’d be more than happy to eat it or serve it to others.
Honestly Tasty’s Ched Spread, Herbi, and Shamembert are perfectly acceptable (vegan!) substitutes for cheese. Even where they don’t accurately reflect the cheese they attempt to model,
they’re still pretty good if you take them on their own merits: instead of comparing them to their counterparts, consider each as if it were a cheese spread or soft cheese in its own
right and enjoy accordingly. I’d buy them again.
Their Bree failed to capture the essence of a good ripe Brie and its flavour profile wasn’t for me something to enjoy outside of its attempts at emulation. And their “Veganzola” Blue
cheese… was pretty grim, but then that’s what I think of Gorgonzola too, so maybe it’s perfect and I just haven’t the palate for it.
Coca-Cola is to test a paper bottle as part of a longer-term bid to eliminate plastic from its packaging entirely.
The prototype is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner.
But the goal is to create a 100% recyclable, plastic-free bottle capable of preventing gas escaping from carbonated drinks.
The barrier must also ensure no fibres flake off into the liquid.
If only somebody could invent a bottle suitable for containing Coca-Cola but 100% recyclable, plastic-free, and food safe.
Oh wait… for the vast majority of its history, all Coca-Cola bottles have met this description!The original Coke
bottles, back in 1899, were made of glass with a metal top. Glass is infinitely-recyclable (it’s also suitable for
pressure-washing and reusing, saving even more energy, as those who receive doorstep milk deliveries already know) and we already have a recycling infrastructure for it in place. Even
where new glass needs to be made from scratch, its raw ingredient is silica, one of the most abundant natural resources on the planet!
Bottle caps can be made of steel or aluminium and can be made in screw-off varieties in case you don’t have a bottle opener handy. Both steel and aluminium are highly-recyclable, and
again with infrastructure already widespread. Many modern “metal” caps contain a plastic liner to ensure a good airtight fit (especially if it’s a screw cap, which are otherwise
less-tight), but there are environmentally-friendly alternatives: bioplastics or cork, for example.
The worst things about glass are its fragility – which is a small price to pay – and its weight (making distribution more expensive and potentially more-polluting). But that latter can
easily be overcome by distributing bottling: a network of bottling plants around the country (each bottling a variety of products, and probably locally-connected to reclamation and
recycling schemes) would allow fluids to be transported in bulk – potentially even in concentrate form, further improving transport efficiency… and that’s if it isn’t just more
ecologically-sound to produce Coke more-locally rather than transporting it over vast distances: it’s not like the recipe is particularly complicated.
In short: this is the stupidest environmental initiative I’ve seen yet this year.

This isn’t really about this particular website, of course (and I certainly don’t want to discourage anybody from the important cause of saving the planet!). It’s about the

If the different land uses of the UK were divided up into their percentage-ratio blocks, what would a 100-second tour of the country

I’m increasingly convinced that Friedemann Friese‘s 2009 board game Power Grid: Factory Manager (BoardGameGeek) presents gamers with a highly-digestible model of the energy economy in a capitalist society.
In Factory Manager, players aim to financially-optimise a factory over time, growing production and delivery capacity through upgrades in workflow, space, energy, and staff
efficiency. An essential driving factor in the game is that energy costs will rise sharply throughout. Although it’s not always clear in advance when or by how much, this increase in
the cost of energy is always at the forefront of the savvy player’s mind as it’s one of the biggest factors that will ultimately impact their profit.
Given that players aim to optimise for turnover towards the end of the game (and as a secondary goal, for the tie-breaker: at a specific point five rounds after the game begins) and not
for business sustainability, the game perhaps-accidentally reasonably-well represents the idea of “flipping” a business for a profit. Like many business-themed games, it favours
capitalism… which makes sense – money is an obvious and quantifiable way to keep score in a board game! – but it still bears repeating.
There’s one further mechanic in Factory Manager that needs to be understood: a player’s ability to control the order in which they take their turn and their capacity to
participate in the equipment auctions that take place at the start of each round is determined by their manpower-efficiency in the previous round. That is: a player who
operates a highly-automated factory running on a skeleton staff benefits from being in the strongest position for determining turn order and auctions in their next turn.
The combination of these rules leads to an interesting twist: in the final turn – when energy costs are at their highest and there’s no benefit to holding-back staff to
monopolise the auction phase in the nonexistent subsequent turn – it often makes most sense strategically to play what I call the “sweatshop strategy”. The player switches off
the automated production lines to save on the electricity bill, drags in all the seasonal workers they can muster, dusts off the old manpower-inefficient machines mouldering in the
basement, and gets their army of workers cranking out widgets!
With indefinitely-increasing energy prices and functionally-flat staff costs, the rules of the game would always eventually reach the point at which it is most cost-effective
to switch to slave cheap labour rather than robots. but Factory Manager‘s fixed-duration means that this point often comes for all players in many games at the same
predictable point: a tipping point at which the free market backslides from automation to human labour to keep itself alive.
The demise of the automated car wash may seem trivial next to these former triumphs of homo technologicus but it sits on the same continuum. It is just one of a gathering
list of technologies that we used to be able to use, but can no longer express (through market or state spending) a purpose for. More worrying, however, is the direction in which we
are willingly going in our collective decision to move from complexity to simplicity. The demise of the automated car wash has not followed a return to the practice of people
washing their own cars (or paying the neighbours’ kid to do it). Instead we have more or less happily accepted serfdom (the use of debt and blackmail to force people to work) and
slavery (the use of physical harm) as a reasonable means of keeping the cost of cleaning cars to a minimum (similar practices are also keeping the cost of food down in the UK).
This, too, is precisely what is expected when the surplus energy available to us declines.
I love Factory Manager, but after reading Watkins’ article, it’ll probably feel a little different to play it, now. It’s like that moment when, while reading the rules, I first
poured out the pieces of Puerto Rico. Looking through them, I thought for a moment about what the “colonist”
pieces – little brown wooden circles brought to players’ plantations on ships in a volume commensurate with the commercial demand for manpower – represented. And that realisation adds
an extra message to the game.
Beneath its (fabulous) gameplay, Factory Manager carries a deeper meaning encouraging the possibility of a discussion about capitalism, environmentalism, energy, and
sustainability. And as our society falters in its ability to fulfil the techno-utopian dream, that’s perhaps a discussion we need to be having.
But for now, go watch Sorry to Bother You, where you’ll find further parallels… and at least you’ll get to laugh as you do
An increasing number of people are reportedly suffering from an allergy to the meat and other products of nonhuman mammals, reports Mosaic Science this week, and we’re increasingly confident that the cause is
a sensitivity to alpha-gal (Galactose-alpha-1,3-galactose), a carbohydrate produced in the bodies of virtually
all mammals except for us and our cousin apes, monkeys, and simians (and one of the reasons you can’t transplant tissue from pigs to humans, for example).
The interesting thing is that the most-common cause of alpha-gal sensitivity appears to be the bite of one of a small number of species of tick. The most-likely hypothesis seems to be
that being bitten by such a tick after it’s bitten e.g. deer or cattle may introduce that species’ alpha-gal directly to your bloodstream. This exposure triggers an immune response
through all future exposure, even if it’s is more minor, e.g. consuming milk products or even skin contact with an animal.
That’s nuts, isn’t it? The Mosaic Science article describes the reaction of Tami McGraw, whose symptoms began in 2010:
[She] asked her doctor to order a little-known blood test that would show if her immune system was reacting to a component of mammal meat. The test result was so strongly positive,
her doctor called her at home to tell her to step away from the stove.
That should have been the end of her problems. Instead it launched her on an odyssey of discovering just how much mammal material is present in everyday life. One time, she took
capsules of liquid painkiller and woke up in the middle of the night, itching and covered in hives provoked by the drug’s gelatine covering.
When she bought an unfamiliar lip balm, the lanolin in it made her mouth peel and blister. She planned to spend an afternoon gardening, spreading fertiliser and planting flowers, but
passed out on the grass and had to be revived with an EpiPen. She had reacted to manure and bone meal that were enrichments in bagged compost she had bought.
Of course, this isn’t the only nor even the most-unusual (or most-severe) animal-induced allergy-to-a-different-animal we’re aware of. The hilariously-named but terribly-dangerous
Pork-Cat syndrome is caused, though we’re not sure how, by exposure to cats and
results in a severe allergy to pork. But what makes alpha-gal sensitivity really interesting is that it’s increasing in frequency at quite a dramatic rate. The culprit? Climate change.
It’s impossible to talk to physicians encountering alpha-gal cases without hearing that something has changed to make the tick that transmits it more common – even though they don’t
know what that something might be.
“Climate change is likely playing a role in the northward expansion,” Ostfeld adds, but acknowledges that we don’t know what else could also be contributing.
A little dated, perhaps: I’m sure that nobody needs to be told nowadays that one of the biggest things a Westerner can do to reduce their personal carbon footprint (after from breeding less or not at all, which I maintain is the biggest, or avoiding air
travel, which Statto argues for) is to reduce or refrain from consumption of meat (especially pork and beef) and dairy products.
Indeed, environmental impact was the biggest factor in my vegetarianism (now weekday-vegetarianism) for
the last eight years, and it’s an outlook that I’ve seen continue to grow in others over the same period.
Seeing these two stories side-by-side in my RSS reader put the Gaia hypothesis in my mind.
If you’re not familiar with the Gaia hypothesis, the basic idea is this: by some mechanism, the Earth and all of the life on it act in synergy to maintain homeostasis. Organisms not
only co-evolve with one another but also with the planet itself, affecting their environment in a way that in turn affects their future evolution in a perpetual symbiotic relationship
of life and its habitat.
Its advocates point to negative feedback loops in nature such as plankton blooms affecting the weather in ways that inhibit
plankton blooms and to simplistic theoretical models like the Daisyworld Simulation
(cute video). A minority of its proponents go a step further and describe the Earth’s changes teleologically, implying a conscious Earth with an intention to
protect its ecosystems (yes, these hypotheses were born out of the late 1960s, why do you ask?). Regardless, the essence is the same: life’s effect on its environment affects the
environment’s hospitality to life, and vice-versa.
There’s an attractive symmetry to it, isn’t there, in light of the growth in alpha-gal allergies? Like:
Today – climate change causes ticks to spread more-widely and bite more humans.
Tomorrow – tick bites cause humans to consume less products farmed from mammals?
That’s not to say that I buy it, mind. The Gaia hypothesis has a number of problems, and – almost as bad – it encourages a complacent “it’ll all be okay, the Earth will fix itself”
mindset to climate change (which, even if it’s true, doesn’t bode well for the humans residing on it).
But it was a fun parallel to land in my news reader this morning, so I thought I’d share it with you. And, by proxy, make you just a little bit warier of ticks than you might have been
In 2014 Henrik Karlsson, a Swedish entrepreneur whose startup was failing, was lying in bed with a bankruptcy notice when the BBC called. The reporter had a
scoop: On the eve of releasing a major report, the United Nation’s climate change panel appeared to be touting an untried technology as key to keeping planetary temperatures at safe
levels. The technology went by the inelegant acronym BECCS, and Karlsson was apparently the only BECCS expert the reporter could find.
Karlsson was amazed. The bankruptcy notice was for his BECCS startup, which he’d founded seven years earlier after an idea came to him while watching a late-night television show in
Gothenburg, Sweden. The show explored the benefits of capturing carbon dioxide before it was emitted from power plants. It’s the technology behind the much-touted notion of “clean
coal,” a way to reduce greenhouse gas emissions and slow down climate change.
Karlsson, then a 27-year-old studying to be an operatic tenor, was no climate scientist or engineer. Still, the TV show got him thinking: During photosynthesis plants naturally suck
carbon dioxide from the air, storing it in their leaves, branches, seeds, roots, and trunks. So what if you grew crops and then burned those crops for electricity, being sure to
capture all of the carbon dioxide emitted? You’d then store all that dangerous CO2 underground. Such a power plant wouldn’t just be emitting less greenhouse gas into the
atmosphere, it would effectively be sucking CO2 from the air. Karlsson was enraptured with the idea. He was going to help avert a global disaster.
Wonderful but horrifying longread about the truth of the theoretical effectiveness of the Paris Agreement. The short: if we’re going to keep global temperature rises under a “bad” 2°C
rather than closer to a “catastrophic” 4°C, we need to take action, but the vast majority of the plans that have been authored on how to do that rely on investment in technologies and
infrastructure that nobody is investing in and that might not work even if we did. We’re fucked, in short. See also this
great video about greening the Sahara in an effort to lock carbon into plants (another great idea that, surprise surprise, nobody’s investing in).
Thanks to the modern electric grid, you have access to electricity whenever you want. But the grid only works when electricity is generated in the same amounts as it is consumed. That
said, it’s impossible to get the balance right all the time. So operators make grids more flexible by adding ways to store excess electricity for when production drops or consumption
About 96% of the world’s energy-storage capacity comes in the form of one technology: pumped hydro. Whenever generation exceeds demand, the excess electricity is used to pump water up
a dam. When demand exceeds generation, that water is allowed to fall—thanks to gravity—and the potential energy turns turbines to produce electricity.
But pumped-hydro storage requires particular geographies, with access to water and to reservoirs at different altitudes. It’s the reason that about three-quarters of all pumped hydro
storage has been built in only 10 countries. The trouble is the world needs to add a
lot more energy storage, if we are to continue to add the intermittent solar and wind power necessary to cut our dependence on fossil fuels.
A startup called Energy Vault thinks it has a viable alternative to pumped-hydro: Instead of using water and dams, the startup uses concrete blocks and cranes. It has been operating
in stealth mode until today (Aug. 18), when its existence will be announced at Kent Presents, an ideas festival in Connecticut.
Because I’m a data nerd, I decided to monitor our energy usage, production, and total cost in order to fully understand the economic impact of our tiny power station. I appreciate that
many of you might not be able to appreciate how cool this kind of data is, but that’s because you don’t have as good an appreciation of how fun statistics can be… it is cool,
If you look at the chart above, for example (click for a bigger version), you’ll notice a few things:
We use a lot more KWh of gas than electricity (note that’s not units of gas: our gas meter measures in cubic feet, which means we have to multiply by around… 31.5936106… to
get the KWh… yes, really – more information here), but electricity is correspondingly 3.2 times more expensive per KWh – I have a separate chart to measure our daily energy costs, and it is if
anything even more exciting (can you imagine!) than this one.
Our gas usage grows dramatically in the winter – that’s what the big pink “lump” is. That’s sort-of what you’d expect on account of our gas central heating.
Our electricity usage has trended downwards since the beginning of the year, when the solar panels were installed. It’s hard to see with the gas scale throwing it off (but again,
the “cost per day” chart makes it very clear). There’s also a bit near the end where the electricity usage seems to fall of the bottom of the chart… more on that in a moment.
What got me sold on the idea of installing solar panels, though, was their long-term investment potential. I had the money sitting around anyway, and by my calculations we’ll get a
significantly better return-on-investment out of our little roof-mounted power station than I would out of a high-interest savings account or bond. And that’s because of the
oft-forgotten “third way” in which solar panelling pays for itself. Allow me to explain:
Powering appliances: the first and most-obvious way in which solar power makes economic sense is that it powers your appliances. Right now, we generate
almost as much electricity as we use (although because we use significantly more power in the evenings, only about a third of what which we generate goes directly into making our
plethora of computers hum away).
Selling back to the grid (export tariff): as you’re probably aware, it’s possible for a household solar array to feed power back into the National Grid: so
the daylight that we’re collecting at times when we don’t need the electricity is being sold back to our energy company (who in turn is selling it,
most-likely, to our neighbours). Because they’re of an inclination to make a profit, though (and more-importantly, because we can’t commit to making electricity for them when they
need it: only during the day, and dependent upon sunlight), they only buy units from us at about a third of the rate that they sell them to consumers. As a result, it’s worth our
while trying to use the power we generate (e.g. to charge batteries and to run things that can be run “at any point” during the day like the dishwasher, etc.)
rather than to sell it only to have to buy it back.
From a government subsidy (feed-in tariff): here’s the pleasant surprise – as part of government efforts to increase the proportion of the country’s energy that
is produced from renewable sources, they subsidise renewable microgeneration. So if you install a wind turbine in your garden or a solar array on your roof, you’ll get a kickback for
each unit of electricity that you generate. And that’s true whether you use it to power appliances or sell it back to the grid – in the latter case, you’re basically
being paid twice for it! The rate that you get paid as a subsidy gets locked-in for ~20 years after you build your array, but it’s gradually decreasing. We’re getting paid a little
over 14.5p per unit of electricity generated, per day.
As the seasons have changed from Winter through Spring we’ve steadily seen our generation levels climbing. On a typical day, we now make more electricity than we use. We’re still having
to buy power from the grid, of course, because we use more electricity in the evening than we’re able to generate when the sun is low in the sky: however, if (one day) technology like
Tesla’s PowerWall becomes widely-available at reasonable prices, there’s no reason that a house like ours couldn’t be totally
independent of the grid for 6-8 months of the year.
So: what are we saving/making? Well, looking at the last week of April and the first week of May, and comparing them to the same period last year:
Powering appliances: we’re saving about 60p per day on electricity costs (down to about £1.30 per day).
Selling back to the grid: we’re earning about 50p per day in exports.
From a government subsidy: we’re earning about £2.37 per day in subsidies.
As I’m sure you can see: this isn’t peanuts. When you include the subsidy then it’s possible to consider our energy as being functionally “free”, even after you compensate for the
shorter days of the winter. Of course, there’s a significant up-front cost in installing solar panels! It’s hard to say exactly when, at this point, I expect them to have paid for
themselves (from which point I’ll be able to use the expected life of the equipment to more-accurately predict the total return-on-investment): I’m planning to monitor the situation for
at least a year, to cover the variance of the seasons, but I will of course report back when I have more data.
I mentioned that the first graph wasn’t accurate? Yeah: so it turns out that our house’s original electricity meter was of an older design that would run backwards when
electricity was being exported to the grid. Which was great to see, but not something that our electricity company approved of, on account of the fact that they were then paying us for
the electricity we sold back to the grid, twice: for a couple of days of April sunshine, our electricity meter consistently ran backwards throughout the day. So they sent a couple of
engineers out to replace it with a more-modern one, pictured above (which has a different problem: its “fraud light” comes on whenever we’re sending power back to the grid, but
apparently that’s “to be expected”).
In any case, this quirk of our old meter has made some of my numbers from earlier this year more-optimistic than they might otherwise be, and while I’ve tried to compensate
for this it’s hard to be certain that my estimates prior to its replacement are accurate. So it’s probably going to take me a little longer than I’d planned to have an accurate
baseline of exactly how much money solar is making for us.
One of the great joys of owning a house is that you can do pretty much
whatever you please with it. I celebrated Ruth, JTA
and I’s purchase of Greendale last year by wall-mounting not one but
two televisions and putting shelves up everywhere. But honestly, a little bit of DIY isn’t that unusual nor special. We’ve got plans for a few other changes to the
house, but right now we’re pushing our eco-credentials: we had cavity wall insulation added to the older parts of the building the other week and an electric car charging port added not
long before that. And then… came this week’s big change.
Solar photovoltaics! They’re cool, they’re (becoming) economical, and we’ve got this big roof that faces almost due-South that would otherwise be just sitting there catching rain. Why
not show off our green credentials and save ourselves some money by covering it with solar cells, we thought.
Because it’s me, I ended up speaking to five different companies and, after removing one from the running for employing a snake for a salesman, collecting seven quotes from the
remaining four, I began to do my own research. The sheer variety of panels, inverters, layouts and configurations (all of which are described in their technical sheets using terms that
in turn required a little research into electrical efficiency and dusting off formulas I’d barely used since my physics GCSE exam) are mind-boggling. Monolithic, string, or
micro-inverters? 250w or 327w panels? Where to run the cables that connect the inverter (in the attic) to the generation meter and fusebox (in the ground floor toilet)? Needless to say,
every company had a different idea about the “best way” to do it – sometimes subtly different, sometimes dramatically – and had a clear agenda to push. So – as somebody not suckered in
to a quick deal – I went and did the background reading first.
In case you’re not yet aware, let me tell you the three reasons that solar panels are a great idea, economically-speaking. Firstly, of course, they make electricity out of sunlight
which you can then use: that’s pretty cool. With good discipline and a monitoring tool either in hardware or software, you can discover the times that you’re making more power than
you’re using, and use that moment to run the dishwasher or washing machine or car charger or whatever. Or the tumble drier, I suppose, although if you’re using the tumble drier
because it’s sunny then you lose a couple of your ‘green points’ right there. So yeah: free energy is a nice selling point.
The second point is that the grid will buy the energy you make but don’t use. That’s pretty cool, too – if it’s a sunny day but there’s nobody in the house, then our
electricity meter will run backwards: we’re selling power back to the grid for consumption by our neighbours. Your energy provider pays you for that, although they only pay you
about a third of what you pay them to get the energy back again if you need it later, so it’s always more-efficient to use the power (if you’ve genuinely got something to use
it for, like ad-hoc bitcoin mining or something) than to sell it. That said, it’s still “free money”, so you needn’t complain too much.
The third way that solar panels make economic sense is still one of the most-exciting, though. In order to enhance uptake of solar power and thus improve the chance that we hit the
carbon emission reduction targets that Britain committed to at the Kyoto
Protocol (and thus avoid a multi-billion-pound fine), the government subsidises renewable microgeneration plants. If you install solar panels on your house before the end of this
year (when the subsidy is set to decrease) the government will pay you 14.38p per unit of electricity you produce… whether you use it or whether you sell it. That rate is
retail price index linked and guaranteed for 20 years, and as a result residential solar installations invariably “pay for themselves” within that period, making them a logical
investment for anybody who’s got a suitable roof and who otherwise has the money just sitting around. (If you don’t have the cash to hand, it might be worth taking out a loan
to pay for solar panels, but then the maths gets a lot more complicated.)
The scaffolding went up on the afternoon of day one, and I took the opportunity to climb up myself and give the gutters a good cleaning-out, because it’s a lot easier to do that from a
fixed platform than it is from our wobbly “community ladder”. On day two, a team of electricians and a solar expert appeared at breakfast time and by 3pm they were gone, leaving behind
a fully-functional solar array. On day three, we were promised that the scaffolding company would reappear and remove the climbing frame from our garden, but it’s now dark and they’ve
not been seen yet, which isn’t ideal but isn’t the end of the world either: not least because Ruth’s been unwell and thus hasn’t had the chance to get up and see the view from the top
of it, yet.
We made about 4 units of electricity on our first day, which didn’t seem bad for an overcast afternoon about a fortnight away from the shortest day of the year. That’s about enough to
power every light bulb in the house for the duration that the sun was in the sky, plus a little extra (we didn’t opt to commemorate the occasion by leaving the fridge door open in order
to ensure that we used every scrap of the power we generated).
Because I’m a bit of a data nerd these years, I’ve been monitoring our energy usage lately anyway and as a result I’ve got an interesting baseline against which to compare the
effectiveness of this new addition. And because there’s no point in being a data nerd if you don’t get to share the data love, I will of course be telling you all about it as soon as I
This is the second part of a three-part blog post about my vasectomy. Did you read the first part, yet?
My vasectomy was scheduled for Tuesday afternoon, so I left work early in order to cycle up to the hospital: my plan was to cycle up there, and then have Ruth ride my bike back while JTA drove me home. For a moment, though, I panicked
the clinic receptionist when she saw me arrive carrying a cycle helmet and pannier
bag: she assumed that I must be intending to cycle home after the operation!
It took me long enough to find the building, cycling around the hospital in the dark, and a little longer still to reassure myself that this underlit old building could actually be a
place where surgery took place.
Despite my GP‘s suggestion to the contrary, the staff didn’t feel the need to take me though their counselling process, despite
me ticking some (how many depends primarily upon how you perceive our unusual relationship
structure) of the “we would prefer to counsel additionally” boxes on their list of criteria. I’d requested that Ruth arrive at about the beginning of the process specifically so that she could “back me up” if
needed (apparently, surgeons will sometimes like to speak to the partner of a man requesting a vasectomy), but nobody even asked. I just had to sign another couple of consent forms to
confirm that I really did understand what I was doing, and then I was ready to go!
I’d shaved my balls a few days earlier, at the request of the clinic (and also at Matt‘s suggestion, who
pointed out that “if I don’t, they’ll do it for me, and I doubt they’ll be as gentle!” – although it must be pointed out that as they were already planning to take a blade to
my junk, I might not have so much to worry about), which had turned out to be a challenge in itself. I’ve since looked online and found lots of great diagrams showing you
which parts you need to shave, but the picture I’d been given might as well have been a road map of Florence, because no matter which way up I turned it, it didn’t look anything like my
genitals. In the end, I just shaved all over the damn place, just to be sure. Still not an easy feat, though, because the wrinkled skin makes for challenging shaving: the best technique
I found was to “stretch” my scrotum out with one hand while I shaved it with the other – a tricky (and scary) maneuver.
After sitting in the waiting room for a while, I was ushered through some forms and a couple more questions of “are you sure?”, and then herded into a curtained cubicle to change into a
surgical gown (over the top of which I wore my usual dressing gown). The floor was cold, and I’d forgotten to bring my slippers, so I kept my socks on throughout. I sat in a separate
waiting area from the first, and attempted to make small talk with the other gents waiting there. Some had just come out of surgery, and some were still waiting to go in, and the former
would gently tease the latter with jokes about the operation. It’s a man thing, I guess: I can’t imagine that women would be so likely to engage in such behaviour (ignoring, for a
moment, the nature of the operation).
There are several different approaches to vasectomy, and my surgeon
was kind enough to tolerate my persistent questions as I asked about the specifics of each part of the operation. He’d said – after I asked – that one of the things he liked about doing
vasectomies was that (unlike most of the other surgeries he performs) his patients are awake and he can have a conversation while he worked, although I guess he
hadn’t anticipated that there’d ever be anybody quite so interested as I was.
Warning: The remainder of this blog post describes a surgical procedure, which some people might find squicky. For the protection of those who are of a weak stomach, some photos
have been hidden behind hyperlinks: click at your own risk. (though honestly, I don’t think they’re that bad)
With my scrotum pulled up through a hole in a paper sheet, the surgeon began by checking that “everything was where it was supposed to be”: he checked that he could find each vas (if
you’ve not done this: borrow the genitals of the nearest man or use your own, squeeze moderately tightly between two fingers the skin above a testicle, and move around a bit until you
find a hard tube: that’s almost certainly a vas). Apparently surgeons are supposed to take care to ensure that they’ve found two distinct tubes, so they don’t for example sever the same
Next, he gave the whole thing a generous soaking in iodine. This turned out to be fucking freezing. The room was cold enough already, so I asked him to close the window while my
genitals quietly shivered above the sheet.
Next up came the injection. The local anaesthetic used for this kind of operation is pretty much identical to the kind you get at the dentist: the only difference is that if your
dentist injected you here, that’d be considered a miss. While pinching the left vas between his fingertips, the surgeon squirted a stack of lidocaine into the cavity
around it. And fuck me, that hurt like being kicked in the balls. Seriously: that stung quite a bit for a few minutes, until the anaesthesia kicked in and instead the
whole area felt “tingly”, in that way that your lips do after dental surgery.
Pinching the vas (still beneath the skin at this point) in a specially-shaped clamp, the surgeon made a puncture wound “around” it with a sharp-nosed pair of forceps, and pulled the vas
clean through the hole. This was a strange sensation – I couldn’t feel any pain, but I was aware of the movement – a “tugging” against my insides.
A quick snip removed a couple of centimetres from the middle of it (I gather that removing a section, rather than just cutting, helps to reduce the – already slim – risk that
the two loose ends will grow back together again) and cauterised the ends. The cauterisation was a curious experience, because while I wasn’t aware of any sensation of heat, I could
hear a sizzling sound and smell my own flesh burning. It turns out that my flaming testicles smell a little like bacon. Or, if you’d like to look at it another way (and I can almost
guarantee that you don’t): bacon smells a little bit like my testicles, being singed.
Next up came Righty’s turn, but he wasn’t playing ball (pun intended). The same steps got as far as clamping and puncturing before I suddenly felt a sharp pain, getting rapidly worse.
“Ow… ow… owowowowowow!” I said, possibly with a little more swearing, as the surgeon blasted another few mils of anaesthetic into my bollocks. And then a little more. And
damnit: it turns out that no matter how much you’ve had injected into you already, injecting anaesthetics into your tackle always feels like a kick in the nuts for a few
The removed sections of my vas, on a tray (actually mine)
You can see the “kink” in each, where it was pulled out by the clamp. Also visible is the clamp itself – a cruel-looking piece of equipment, I’m sure you’ll agree! – and the discarded
caps from some of the syringes that were used.
The benefit of this approach, the “no-scalpel vasectomy”, is that the puncture wounds are sufficiently small as to not need stitches. At the end of the surgery, the surgeon just stuck a
plaster onto the hole and called it done. I felt a bit light-headed and wobbly-legged, so I sat on the operating table for a few minutes to compose myself before returning to the
nurses’ desk for my debrief. I only spent about 20 minutes, in total, with the surgeon: I’ve spent longer (and suffered more!) at the dentist.
By the evening, the anaesthetic had worn off and I was in quite a bit of pain, again: perhaps worse than that “kick in the balls” moment when the anaesthetic was first injected, but
without the relief that the anaesthetic brought! I took some paracetamol and – later – some codeine, and slept with a folded-over pillow wedged between my knees, after I discovered how
easy it was to accidentally squish my sore sack whenever I shifted my position.
The day after was somewhat better. I was walking like John Wayne, but this didn’t matter because – as the nurse had suggested – I spent most of the day lying down “with my feet as high
as my bottom”. She’d taken the time to explain that she can’t put a bandage nor a sling on my genitals (and that I probably wouldn’t want her to, if she could), so the correct
alternative is to wear tight-fitting underwear (in place of a bandage) and keep my legs elevated (as a sling). Having seen pictures of people with painful-looking bruises and swelling
as a result of not following this advice, I did so as best as I could.
Today’s the day after that: I’m still in a little pain – mostly in Righty, again, which shall henceforth be called “the troublesome testicle” – but it’s not so bad except when I forget
and do something like bend over or squat or, I discovered, let my balls “hang” under their own weight, at all. But altogether, it’s been not-too-bad at all.
Or, as I put on my feedback form at the clinic: “A+++. Recommended. Would vasectomy again.”
(thanks due to Ruth, JTA, Matt, Liz, Simon,
Michelle, and my mum for support, suggestions, and/or fetching things to my bed for me while I’ve been waddling
around looking like John Wayne, these past two days)
What’s no joke, though, is the human population explosion. There’re just too damn many of us, as I explained last year. That’s the primary reason
behind my decision, held for pretty-much the entirety of my adult life, to choose not to breed.
I’m fully aware that the conscious decision to not-breed by a single individual – especially in the developed world – makes virtually no difference to the global fate of humanity. I’m
under no illusion that my
efforts as a vegetarian are saving the world either. But just like the voter who casts a ballot for their party – even though they know it won’t make a difference to the outcome of
the election – I understand that doing the right thing doesn’t necessarily have to have a directly quantifiable benefit.
That’s why I’m finally taking the next obvious step. Next month, after literally years of talking about it, I’m finally going to put my genitals where my mouth is (hmm… maybe that
wasn’t the best choice of words)! Next week, I’m getting a vasectomy.
I first asked a doctor about the possibility of vasectomy about a decade ago. He remarked upon my age, and said – almost jokingly – “Come back in ten years if you still feel the same
way!” I almost wish that I still had the same GP now, so that I could do exactly that. Instead, I spoke about a year ago to my (old) GP here in Oxford, who misled me into thinking that
I would not be able to get the surgery on the NHS, and would have to have it done privately. Finally, a second doctor agreed to sign off their part of the consent form, and I was good
to go. The secret, it seems, is persistence.
I’m sure that this is a decision that won’t be without it’s controversies. And believe me: over the course of the most-of-my-life-so-far that I’ve hinted at or talked about doing this,
I’m pretty sure I’ve heard all of the arguments. Still: I feel like I ought to pick up on some of the things I’ve heard most-often –
What if you change your mind?
Even despite medical advances in recent decades in vasectomy reversal, vasectomy should still be considered a “one way trip”. Especially when I was younger, people seemed concerned that
I would someday change my mind, and then regret my decision not to spawn children.
I suppose that it’s conceivable – unlike my otherwise potential offspring – but it’s quite a stretch, to believe that I might someday regret not having children (at least not
biologically: I have no problem with adopting, co-parenting, fostering, or any number of other options for being involved in the upbringing of kids). I honestly can’t see how that’d
come about. But even if we do take that far-fetched idea: isn’t it equally possible that somebody might ultimately regret having children. We take risks in our lives with
any choice that we make – maybe I’ll someday regret not having taken my degree in Law or Chemistry or Rural Studies. Well then: c’est la vie.
Do you just not like children?
Children are great, and I’d love to get the chance to be involved in raising some. However, I don’t define myself by that wish: if I never have the opportunity to look after any kids,
ever, then that wouldn’t be the worst thing in the world: I’d just spend my years writing code in a house full of cats. I have no doubt that raising children is great (for many people),
but just like there are plenty of people for whom it’s not great, there are also plenty of people – like me – who could be happy either way. No biggie!
There are those who have said that this laid-back “take it or leave it” approach, especially when coupled with the more-recent act of rendering myself infertile, will make me less
attractive to women. Leaving aside the implicit sexism in that claim, wouldn’t a fair retort be to point out that a woman who is looking for monogamous breeding probably isn’t
my “type” to begin with!
But you should be breeding?
This argument’s usually based on the idea that I’m somehow genetically superior and that my children wouldn’t be such a strain on the world as somebody else’s, or that
mine would have a significantly better-than-average chance of curing cancer, solving world hunger, or something.
And let’s face it, any child of mine would be just as likely to be the one to build a really big bomb. Or create a super-virus. Or just engineer the collapse the world’s economies into
a prehistoric barter economy in a technophobic future anarchy. Attaboy.
In any case, I’m pretty sure that my personal contribution to the betterment of the world ought not to be a genetic one. I’d like to make a difference for the people who are around
right now, rather than hypothetical people of the future, and I’d far rather leave ideas in my wake than a handful of genes. I’m sure that’s not the case for everybody, but then – it
doesn’t have to be.
Or are there some arguments that I’ve missed? If you’re among the folks who feel really strongly about this, then you’ve got about seven days to make them, and then it’s off to the
clinic for me! Just remember: what’s right for me isn’t necessarily what’s right for you, and vice-versa. Just because I use Emacs doesn’t mean that some other, inferior text editor might not be the right choice for you.
I wonder what my surgeon might say to the possibility of me live-tweeting the process? Would anybody be interested? (I promise not to include any photos.)

[disclaimer: this post appears just days after some friends of mine announce their pregnancy;
this is a complete coincidence (this post was written and scheduled some time ago) and of course I’m delighted for the new parents-to-be]
In October, the world population is expected to reach seven billion. Seven fucking billion. I remember
being a child and the media reports around the time that we hit five billion: that was in the late 1980s. When my parents were growing up, we hadn’t even hit three billion. For the
first nine or ten thousand years of human civilisation between the agricultural revolution and the industrial revolution, the world population was consistently below a billion. Let’s
visualise that for a moment:
How big is our island?
Am I the only one who gets really bothered by graphs that look like this? Does it not cause alarm?
We have runaway population growth and finite natural resources. Those two things can’t coexist together forever. Let’s have a look at another graph:
This one is taken from a wonderful comic called St. Matthew
Island, about the real island. It charts the
population explosion of a herd of reindeer introduced to the island in the 1940s and then left to their own devices in a safe and predator-free environment. Their population ballooned
until they were consuming all of their available resources. As it continued to expand, a tipping point was reached, and catastrophe struck: without sufficient food, mass starvation set
in and the population crashed down from about 6,000 to only 43. By the 1980s, even these few had died out.
There are now no reindeer on St. Matthew Island. And it looks like this 40-year story could serve as a model for the larger, multi-century, world-wide population explosion that humans
Humans are – in theory at least – smart enough to see what’s coming. If we continue to expand in this way, we risk enormous hardship (likely) and possible extinction (perhaps). Yet
still the vast majority of us choose to breed, in spite of the overwhelming evidence that this is Not A Good Thing.
But even people smart enough to know better seem to continue to be procreating. And perhaps they’re right to: for most people, there is – for obvious evolutionary reasons – a biological
urge to pass on one’s genes to the next generation. During a period of population explosion, the risk that your genetic material will be “drowned out” by the material of those
practically unrelated to you. Sure: there might be a complete ecological collapse in 10, 100 or 1000 years… but the best way to ensure that your genes survive it is to put them into as
many individuals as possible: surely some of them will make it, right? Just like buying several lottery tickets improves your chances of hitting the jackpot.
On a political level, too, a similar application of game theory applies: if the other countries are going to have more people, then our country needs more people
too! Very few countries penalise families for having multiple children (in fact, to the contrary), and those that do don’t do so very effectively. This leads to a “population arms
race”, and no nation can afford to fall behind its rivals: it needs a young workforce ready to pay taxes, produce goods, pay for the upkeep of the retired… and conceive yet more
The same tired arguments
Mostly, though, I hear the same tired arguments for breeding [PDF]: cultural conditioning
and social expectations, a desire to “pass on” a name (needless to say, I have a different idea about names
than many people), a xenophobic belief that the world needs “more people like us” but “less like them”, and worry that you might regret it later (curious how few people seem to consider
the reverse of this argument).
For me, the genetic problem is easy enough to fix: if your children’s genes are valuable to you because of their direct relationship (50%) to your genes, then presumably your brother’s
(50%) and your niece’s (25%) are valuable to you to: more so than that of somebody on the other side of the world? I just draw the boundary in a different place – all of us humans share
well over 99% of our DNA with one another anyway: we’re all one big family! We only share a lower percentage with other primates, a lower percentage still with other mammals, and
so on (although we still share quite a lot even with plants).
The similarity between you and your children is only marginally more – almost insignificantly so – than the similarity between you and every other human that has ever
If you’re looking for a “family” that carries your genetic material: you’re living in one… with almost seven billion brothers, sisters, cousins, uncles and aunts! If you can expand your
thinking to include the non-human animals, too, well: good for you (I can’t quite stretch that far!). But if you’re looking to help your family survive… can you expand that thinking
into a loyalty to your species, instead, and make the effort to reduce population growth for the benefit of all of us?
The other argument I frequently see is the “replacement” argument: that it’s ethically okay for a breeding pair of humans to have exactly two children to “replace” them. This argument
has (at least) three flaws:
The replacement is not instantaneous. If a couple, aged 30, have 2 children, and live to age 80, then there are 50 years during which there are four humans taking up space,
food, water and energy. The problem is compounded even further when we factor in the fact that life spans continue to increase. If you live longer than your parents, and your children
live longer than you, then “replacement” breeding actually results in a continuous increase in total population.
Even ignoring the above, “replacement” breeding strategies only actually works if they’re universal. Given that many humans will probably continue to engage super-replacement level
reproduction, we’re likely to need a huge number of humans to engage in sub-replacement level or no reproduction in order to balance it out.
It makes the assumption that current population levels represent a sustainable situation. That might or might not be true – various studies peg the maximum capacity
for the planet at anywhere between one and a hundred billion individuals, with the majority concluding a value somewhere between four and ten billion. Given the gravity of the
situation, I’d rather err on the side of caution.
“Do you not like children, then?” I’m sometimes asked, as if this were the only explanation for my notion. And recently, I’ve found a new analogy to help explain
myself: children are like bacon sandwiches.
Children are like bacon sandwiches for five major reasons:
Like most (but not all) people, I like them.
I’d love to have them some day.
But I choose not to, principally because it would be ethically wrong.
I don’t want to prevent others from having them (although I don’t encourage it either), because their freedom is more important than that they agree with me. However, I’d like
everybody to carefully consider their actions.
They taste best when they’re grilled until they’re just barely-crispy. Mmm.
The reasons are similar, though: I care about other humans (and, to a much lesser degree, about other living things, especially those which are “closer” family), and I’d rather not be
responsible, even a little, for the kind of widespread starvation that was doubtless experienced by the reindeer of St. Matthew Island. Given the way that humans will go to war over
limited resources and our capacity to cause destruction and suffering, we might even envy the reindeer – who “only” had to starve to death – before we’re done.
