Have you turned off the light the other day? Will we have enough energy in the future to afford turning off lights whenever we want to? What if we could power devices around us with simple energy source like the flowing of the blood or the beating of our own hearts? Wouldn’t that be eco-friendly?

According to researchers working on piezoelectric nanowires your own blood could be use to power up small devices like iPods. They have discovered how to use zinc oxide nanowires to generate electricity when subjected to mechanical stress. The nano things would be implanted right under your skin and then the rest should be fairly easy. The technology doesn’t have a date yet so in the mean time keep those regular chargers around.

MobileWhack was at the New York International Auto Show 2008 (last day is today!) that happened at the Javits Convention Center in New York. There were a host of new/concept cars on display including the Honda FCX Clarity - a fuel cell car. The fuel-cell stack in Clarity converts hydrogen fuel and oxygen into electricity that is then used to drive the engine. The end result is, you guessed it, water vapor, making it a truly zero-emission alternative.

As you can see, the current FC stack from Honday is much more compact compared to one they had in 1999. The FCX Clarity motor’s rotor shaft has a hollow construction where the driveshaft passes through the center in a coax configuration, allowing the motor and gearbox to be combined into a single unit.

The Clarity is currently in limited availability in Southern California.
