This is so cool. Something along this same concept line was going to be part of the power plant gym, whereby a person would run up a flight of stairs with the weight, deposit it onto the line, which upon descent would crank a generator. Then, you run back down the stairs, retrieve the weight, and start over.
This idea is way better. Fund it if you can.
be great
