Human Energy in Picowatts

Episode 2 of Ultra Low Power Bioelectronics gives a really interesting perspective on how much power the cell and the human body generates. We, as animals, generate about 100W just standing. A cow is more like 950W. Each of our cells operates on about a picowatt. The discussion moves from that to examples of low power system design, applicable to cars or electronics. Imagine if we could harness the sunlight that fell on our skin in order to power a 1 microwatt cell phone?
