In [this video](https://youtu.be/umN2iHsw3UY?t=479) a lego motor lifts ~54kg using gear ratios, how can this be possible when the motor only lifts ~3kg by itself? Isn’t that like putting 1 energy into something and getting 18 out of it?

Think of gears like levers: You trade a lot of distance at a little force for a short distance with a lot of force. You don’t end up with any more energy overall, it just applies over an adjusted distance.
