It's a shock no one thought of it before, but a new development to provide green electricity could change the way the world powers itself. An engineering team from the Technion put together a cutting edge project that places solar panels on helium balloons. The balloons are then placed on a cable, and can be stacked one of top of the other.
Prototypes are rough now, but the design should be easy to streamline. Designers think the first models could be available in the next year - with each balloon providing the same amount of electricity
as 25 square meters of solar panels. That's enough to power a washer and dryer for an entire year!
The goal is to make the balloons available to the masses - and for a good price. The finished model made for consumers could cost as little as $4,000 dollars. It's an example of how a simple idea can change the world. 4/10/2008
