Inflatable light on solar energy

Yes, this is very very smart. Have a look at Luminaid. They created an inflatable light that recharges on solar energy. 5 hours of sunlight will give you 8 to 10 hours of night light!

A standard light costs $18.95 (at least that is what their website says as I type this).

Brilliant!
