Dyson energy bracelet uses wrist action to boost your gadget's
juice  This unassuming wristband is one of the entries in the
2009 James Dyson Awards. It's actually a recharger that
harnesses the wearer's energy thanks to the Seebeck effect,
which converts temperature differences into energy. The
brainchild of four French students — Camille Lefer, Clément
Faydi, Mathieu Servais and Mickaël Denié — the energy bracelet
should give you an extra ten minutes' or so of talk time on your
mobile, or fire up your iPod or camera when the battery is in
the red.  Wear it as a bracelet (I'm not sure whether it can
shoot sticky web stuff from your wrist should you want to
immobilize a traffic cop, however) and then plug your gadget
into it using a universal micro USB port when it's low on juice,
and you're far from a socket. The gallery makes it look pretty
gorgeous, and there's a video explaining how it works below.
