Solar-Powered Headphones, FM Radio Only  At first we thought
these solar-powered headphones had an MP3 player inside, but no,
it's just an FM radio. But still, if you get stuck on Gilligan's
Island, as long as it's sunny this little headpiece could give
you updates about upcoming storms for years. Each hour of
sunlight will give you one to three hours of listening pleasure.
It's 19.9, or about $37.  Product Page [Paramount Zone, via
