Expo Notes: MyFC's PowerTrekk charges your iPhone through science

The MyFC PowerTrekk is a novel accessory for powering your iPhone. Just add water.

The company's booth on the Macworld/iWorld show floor was one of a very few where visitors could expect a science lesson along with the product demonstration. The product in question? It's for charging your iPhone or other USB-connecting device, with a special focus on clean technology: hydrogen fuel cells.

The approximately $200 charging unit, available in green, yellow, and orange versions, uses a disposable power pack on one side; on the other side, you add about a tablespoon of water. As the water runs through the material inside the power pack, the H2O breaks down into its component parts: hydrogen and oxygen. The hydrogen is what's needed for the MyFC to generate power--enough power, the company says, to charge up an empty iPhone twice. The charger can output five watts.

You get three power packs when you buy the PowerTrekk; each is one-time-use only. You can pick up additional three-packs for $10.
