Floating Energy Collecting Solar Balloons

Sometimes one of the easiest solutions available is also the best. This incredibly simple design powerfully addresses classic problems of solar energy collection. It is very low-impact, using a minimum of materials to harness the energy of the sun. It is spatially liberated, with floating elements that could essentially be added anywhere (urban or rural and in residential or emergency situations) without taking up any real estate or requiring excessive space or time to ship.
