PowerTrekk hydrogen fuel cell power for your smartphone

TreeHugger gives us the good news on an alternative power source:

Add a tiny hydrogen fuel cell and a tablespoon of water to the PowerTrekk and it will charge your smart phone, digital camera, GPS, and/or virtually any other gizmo that takes juice via a USB cable. Unlike solar chargers, the lightweight (240 grams or 8.5 oz) PowerTrekk is not reliant on hours spent lazing about in the sun, it's ready to go as soon as you turn it on. The only by-product said to be emitted is water vapour. The actual PowerPukk fuel cell is itself said to be considered safe enough to be allowed onboard as part of your aircraft cabin baggage.

PowerTrekk is targeted at three applications. 1. outdoor enthusiasts and 2. business people in remote locations away from powerpoint recharge facilities. And 3. emergency situations when normal electrical power is shut down.
