Next Year, Christmas 2010 Gift Idea

It's logical, green, useful, and everyone should have one.
A human powered low voltage, 2.5Watt device charger (link here).
They're asking $150 for them this year, as it's a start up company, and demand will out-strip supply. Next year, I estimate they'll be 1/2 as expensive - or at least much more available.

Helpful after the next terrorist attack, EMP discharge, hurricane, ice storm, or zombie invasion. =)
