SRI International is developing a new kind of boot for our armed
forces. Funded by a DARPA contract, the heel of the boot has layered
polymers in honeycomb form that generate electricity as the soldier
walks. At normal walking pace, the prototypes generate about half a
watt, but two watts is not far off. Some day in the near future 20-pound
battery packs for personal communications and navigation gear will be
a thing of the past.
