Homemade/DIY gravity light/gravity generator that powers LEDs using falling masses giving enough light to read by. The masses are water bottles that fall for around 12 minutes before needing to be lifted back up. A capacitor stores excess energy to keep the light lit long enough to do that. The gravity light was originally invented by Deciwatt.
