Get hot, get bothered, get your iPhone charged

Graduate student Corey Hewitt shows his Power Felt
Plug it in.  Charge it up.  We forget there are all different kinds of energy.  Your little brother running around is using energy....wasting energy?  Light a campfire, that is another kind of energy.  Most energy you can convert from one to another.  Get on a bicycle, hook it up to a generator and you can make electricity.  Scientists at Wake Forest University are looking at harvesting energy from body heat to power different devices.  The new material which is called "Power Felt" is made of carbon nanotubes embedded in a plastic fabric that take heat and make electricity.  Electricity to power a cell phone or other electronic gadgets.  So the next time you are stranded on Everest you can pull out your Power Felt blanket and power up your cell call for help!!
