Electric jackets

Thin thermal jackets with compartments for fuel cells for warmth and other apps

With the advent of hydrogen fuel cells and metal air fuel cells, wouldnt it be logical to carry along your fuel source wherever you go? Would be excellent in winter - although the jacket will likely be as heavy if not slightly more, much less cumbersome and produces heat. For anyone using any computer technology plug it in to your jacket for recharge etc.

Disadvantage: doesnt work in summer or non air conditioned places.
