SunHope solar balloons

"The design is also ideal for a multitude of off-the-grid applications, with the potential to bring power to deserts, isolated islands, ocean-bound freighters, and heavily forested landscapes. Additionally, the balloons’ eminently deployable nature makes them perfect for disaster and emergency situations, since the balloons are quick to set up and can be delivered via air. Cory and Gurfil have constructed several prototypes and have conducted research to show that a 10 ft balloon could provide around a kilowatt of energy (equivalent to 25 square meters of solar panels). Their target cost is $4,000 per balloon, compared to the $10,000 it would cost for a solar field producing the same amount of energy."
