Posted March 27, 20204 yr This Lego Technic MOC has over a billion to 1 gearing ratio. It is designed to resemble an architectural tower structure. I measured the input speed of over 3000 RPM using a digital tachometer and calculate the rate of rotation of the tower top to be about 222 days per rotation. This design has no purpose what so ever other than to look good and make a lot of noise. This idea was suggested and inspired by one of the eurobricks contributors.
March 27, 20204 yr Looks interesting, I like the color scheme. Watching that slowest gear is worse than watching paint dry, but I guess we all have lots of time these days! Edited March 27, 20204 yr by JGW3000
March 27, 20204 yr Nice. How about a video live stream showing the final axle making a full rotation in the name of LEGO science? Also to verify your calculations of 222.5 days?

However the whole thing will probably be broken by then LOL. On 3/28/2020 at 5:26 AM, dr_spock said: Nice.

Yes good idea - but you have to promise to watch all of it!
March 29, 20204 yr You should drive the thing the other way, turning the slow side, gearing up one billion times and see what happens when the fast side is doing 1 billion rpm.

I'd like to see any machine do that let alone a Lego one! You'd be close to going faster than the speed of light which is about 3e8 m/s. So if for example the bottom axle had a 1 lego unit piece on it (8mm) then for every revolution the outside edge will travel at the distance 8mm x 2 x pi which is about 0.05 m. So you'd need to spin the top axle at only 6 revs/sec (360 RPM) to get 6 x 1,000,000,000 x 0.05 = 3e8 m/s == SPEED OF LIGHT! Let's start that project.
