An end to recharging for mobile phones: “The plan is to replace rechargeable batteries in mobile devices with a miniature version of the
hydrogen fuel cell used to power electric cars, and recharge it with a super-efficient solar cell built
into the devices.

Until now, the tiny amount of space available in a mobile phone or PDA was too small to allow
integration of fuel cells and solar cells, Fraunhofer researchers told ZDNet. And it is a race against
time: as mobile electronic devices shrink in size and increase in functionality, they draw more
power. Manufacturers of solar cells meanwhile continue to raise the efficiency of their products —
some have achieved an efficiency of almost 25 percent — but they are still much too expensive for
the mass market.” ZDNet

“These are only preliminary results, but already they look quite interesting. I’m closer now to being
