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.)
This machine has a gear reduction of 1 to 10 ^ 100. In order
to get the last gear to turn once you’ll need to spin the first one a
google [sic] amount around. Or better said you’ll need more energy than
the entire known universe has to do that. That boggles my mind.
