You have probably heard of Warren Buffett and Bill Gates pledging to give their wealth away, but there is another Billionaire as well who is doing this (prior to death too).

Billions in Change (42min) Short version (3.18min) He invented the Free Electric. A bicycle like device which produces energy while getting you fit. One hour peddling gives 24 hours of electricity. Billions in Change and a few other devices. He is also constructing hospitals in remote areas of India. Billions in Change looks like it just launched and this should have a huge impact this year and onwards.
