Harvesting Energy from the Human Body

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."

I think you might be confusing kilocalories with kilogram-calories :)

1 gram of carbohydrates contains 4 calories, so does protein. Fat contains 9 cal per gram. But I've read that you need to burn 6000 kcal in order to lose 1 kg of fat from body so I say your fleet must a really big one :)

Actually, I think you're confusing the calorie with the Calorie (see the capital C there? see? see? there's a huge difference there).

Apparently some whizz-PR-kids thought it would be good PR if they lost the Kilo-multiplier in their energy description, so they decided that the Kilo- be replaced with a capital C. Well, all in all, if you're dealing with calories, you know you're in trouble. Check out the Wikipedia page on the Calorie. You'll see there are about a zillion different definitions for the calorie.
