How does he make the claim it is powered by gravity? It is powered by muscle power.

Interesting. I hope this isn't another Bigfoot story.

It is a small light driven by a bag of whatever being pulled down by gravity. The bag gets its potential energy not from gravity but by muscle power. Nothing that interesing except the concept.

It still sounds interesting. It beats cranking on a little generator.
