thought this quite interesting. perhaps soon you need never worry about your laptop running out of power again:)
Previously ignored energy sources are being revisited as both the global will to conserve energy and the technological means to generate it radically improve. Electromagnetic radiation from our cities, acoustic noise and stray radio waves are now being re-classified as potential power sources and the human body itself is being re-examined as a battery thanks to advances enabling the energy from body heat, motion and even blood pressure to be harnessed. A new thermoelectric system created by researchers from the Fraunhofer Institute is at the forefront of these developments - running on a miniscule 200 millivolts the device is able to create an electrical charge from body heat and could lend itself to an endless array of applications that go way beyond powering your own mobile phone.
