Electricity from gravity energy storage
For centuries, the original "mass-market" computer, the mechanical time-keeping clock, was typically powered by slowly releasing the energy stored in a mass by displacing it by hand against the force of gravity. Now this storage method is being explored by Deciwatt as a SMALL-SCALE means of generating electricity. Please see http://deciwatt.org/ and http://www.youtube.com/watch?v=5ovoBKuX5II
Our sincere thanks go to Science Friday, for bringing our attention to this effort; too bad their story lead-in suggests that their reporter never passed high-school physics, or even sadder yet, attended an American high-school which passed her in physics. Read and hear their story at http://www.sciencefriday.com/segment/01/18/2013/inventors-design-lamp-powered-entirely-by-gravity.html
Hydropower is a well-established LARGE-SCALE technology which works in the same way as the Deciwatt method, but with the sun storing the energy to be released, by evaporating water molecules, to move them further away from the center of the earth. In recent years, scaling down this technology is also being explored..
