Printed Machine with Concrete by 3DTOPO – Thingiverse:”This is a printable version of Machine with Concrete. The sculpture is a series of twelve 50:1 worm gears, with each gear reducing 1/50th of the previous gear. With 12 gears, the final gear ratio is a mind boggling 244,140,625,000,000,000,000 : 1 (244.14 quintillion to 1). With the first gear spinning at 200RPM it would take over 2 TRILLION years for a single revolution at the end of the machine, so the final drive shaft can be embedded in concrete or plaster.”

“With just 1 foot-pound input, it would develop 244.14 quintillion foot pounds of torque!!! Of course, no known material could survive that kind or torque without tearing itself to shreds.”
