Body Heat to power cell phones?

Science Daily has an article describing how silicon nanowires can be used to capture body heat, and use that energy to power a wide array of devices. Some examples could be the Department of Energy’s hydrogen fuel cell-powered “Freedom CAR,” and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices.

Apparently the human body generates over 25,000 BTUs in body heat, and more bioelectricity than a 120V battery. That should be enough to power a cell phone, and then some. Hopefully the machines won’t find out how efficient we are at generating energy…
