Probably worth adding that you can already buy essentially the same thing, except powered by a hand crank, for $15-20 on Amazon.

A 3.5 inch crank held between my thumb and forefinger doesn’t seem like a great way to generate electricity. I would much rather lift 50lbs a few feet every half hour than spin a tiny crank.
