Science Friday: power from gravity, deciwatt

[Hal Murray]

Their target is light in Africa.   They are only getting 30 mW to 1/2 W so 
the name is appropriate.  That's enough for illumination from LEDs.

It's not likely to be useful for OLPC any time soon.  It might be something 
to keep an eye on.

In the meantime, it might make a nice toy.  :)
