To celebrate being alive for a billion seconds, Daniel Bruin built a machine with 100 gears with a 10-to-1 gear ratio…meaning that the overall gear ratio is a googol-to-one. (A googol is 1 with 100 zeros.)
To turn the last gear in this train one full revolution, you’d need to turn the first gear 10,
By my estimation, that’s enough gearing to allow you to winch the entire solar system, by hand, with ease. Assuming you can find a tow hitch on it somewhere.
