A light powered by gravity?

I wanted to share a video regarding a light that is intended to replace kerosene lamps in areas of the world where power sources are scarce and hard to come by. Enjoy the video above, and leave a comment if you would like to share an idea or reflection about the video or about another technology that is related, I would love to hear it.

Oh and before I forget I have a project Ive been working on for almost a year coming up on my blog, there will be pictures, videos, and some brief descriptions :))))))

Gravity pulls, and the lights glow, and the wisdom continues as I go…
