When I first saw this light introduced on the YouTube channel "Smarter Every Day", I knew I had to write about it.
This is the kind of tech I love to see. Powered by something we literally do have an infinite amount of, gravity.
Here is the S.E.D. video I just referenced:
And here is what the creator of GravityLight, Deciwatt has to say about their unique invention:
"GravityLight is a lamp that is designed to hang from suitable fixtures in a house or dwelling. It uses a bag that can be filled with heavy items and winched up. As the bag descends it drives a generator through a gearbox which provides direct electrical power for a single LED. Additional SatLight lamps can be connected to the main GravityLight unit to extend lighting. Multiple Satlights can be linked together (recommended max of 4)." -http://deciwatt.global/technology/
For a video from the Deciwatt people about GravityLight, look here:

Here's a picture of GravityLight with 2 "Satlights". The satlights are excellent and necessary, light not directed where we need it is somewhat useless.
If you would like more information about GravityLight or the Deciwatt company, it's available at their official website, http://deciwatt.global/.
