No perpetual motion machine just yet

I need to think these things through.

Mobile Magazine described a new phone concept:

Motorola has partnered up with Angstrom Power and the net result is a Motorola SLVR L7 cell phone that actually gets its power straight from the water tap.

Sort of.

[T]he cell phone prototype is powered by hydrogen. The other half of the equation is a desktop fueling station that produces hydrogen from water, storing the particles in a metal hydride storage. The hydrogen molecules are then passed through a fuel cell membrane which strips the electrons to power the phone.

The information comes from Mobilewhack, which previously discussed Angstrom Power and Motorola:

The Micro Hydrogen, a concept by Angstrom Power, is a combination of many factors including a refillable hydrogen storage tank, fuel cell architecture and micro-fluidics. Angstrom has been testing the prototype on Motorola Slvr L7 phones. The technology can reportedly double the usual talk time and full recharge the battery within ten minutes.

So right when I'm getting all excited, Mobile Magazine writer Michael Kwan asks one little itty bitty question:

The question that remains, however, is what powers the desktop fueling station?
