Harvesting Energy from the Human Body 160
Late-Eight writes "Scientists at the Georgia Institute of Technology are working on a new type of nanogenerator that could draw necessary energy from flowing blood in the human body. The hope is to incorporate the new nanogenerator into biosensors, environmental monitoring devices and even personal electronics that will require no fuel source, internal or external. Once completed, this new cellular engine could find various applications, even beyond medicine."

They're talking microamperes and like 0.5 volts so that makes it about microwatts of power; one microwatt of power over the course of one day is something 0.0864 joules, or 0.021 calories, and those are normal calories, not the food calories (which are really kilocalories). Doesn't look like a whole lot, compared to the energy an average person consumes in a day (2000 kcal, that's two million calories!).
