Dr. Pini Gurfil and his doctoral student Yossi Corrie head the project that may bring balloons bobbing around in the sky in a city near you. Are they safe for birds and other animals, we don't know. But the same cable that brings the helium to the balloon will also carry the electricity to the ground, reports the JPost. And your home may require only one or two balloons.
These solar cell coated helium balloons could be used to supply electricity to ships and homes in jungles, deserts and other isolated spots off electricity grids. Beyond that, Gurfil and Corrie hope that homes in cities around the world will get their electricity from such balloons. If they were mass produced, their cost could be reduced below the estimated $700 per square meter of today's solar cells.
Fancy having some balloons bounce over your house? ::Jerusalem Post
