A response to 3D Printer Academy's video "How long will it take for the last gear to spin?" from Aug 28, 2021. I remixed the gearbox to use a small attached DC motor running off a 9v plug.
Using a gear ratio of 70,368,744,177,664 : 1 and a speed of 2450rpm my math puts the time it would take the last gear to make one revolution at well over 54 thousand years (54,645). And just one tenth of a gram of pressure turning the first gear could lift over 1.5 billion pounds, it would just take several millennium to move a couple of millimeters.
My math skills are about as sharp as my speeling skills so please feel free to correct me in the comments.
