Weight Driven Generator.

Using gravity to generate watts

This is pretty small scale but it’s a proof of concept.   The idea came from needing a small amount of light for an outhouse. He decided to use a weight that the “user” could lift up a few feet and let gravity do the rest.

His website has a lot of cool info on this project. He was able to light an LED and charge a battery for a few minutes by lifting just over 1 pound of weight up 4 feet.

Here’s a video of him testing it out.
