Wow, that's neat. Hopefully we can start applying that technology soon.

On a related note, here's another related story of sorts, with grad students building an electricity-generating merry-go-round for a Ghana school.

Now think of how much energy could be generated if we hooked up playground equipment so that it could generate electricity! I'm wondering if there's a way we could do that worldwide.

That's really cool. If there was just a way for solar energy to get enough energy through daylight and be able to store enough excess to use at night, that would be great.

Wasn't this already developed by some other guys

Finally! Some good news! I mean seriously, The economy, Hurricanes, Companies closing and Gas...

...but at least we have this now!
