His name is Kelvin Doe. When he make music he goes by the name DJ Focus. He has taught himself how to build batteries, generators, and transmitters, all from parts he finds in the trash. He's the youngest person ever to be invited to the M.I.T. Visiting Practitioners Program. His next goal is to build a windmill in his Sierra Leone community that will provide his neighbors with electricity.
Kevin's truly inspiring.
