Wow…. this is an incredibly brilliant idea. It is a cheap, fun, maintainable way to provide safe drinking water in Africa.
And of course I can’t help applying this to politics, and Barack Obama’s naysayers. Who says he can’t he make meaningful changes or that we can’t afford to solve our problems – even now. At least some of the problems of this world could be solved with one “Aha!” moment. I hope Obama will surround himself with a host of brilliant Aha thinkers!
