Human batteries — pump it up, we need some blood
» Power from blood could lead to ‘human batteries’ – smh.com.au:
“A device that produces electricity from blood could be used to turn people into ‘human batteries’.
Researchers in Japan are developing a method of drawing power from blood glucose, mimicking the way the body generates energy from food. Theoretically, it could allow a person to pump out 100 watts – enough to illuminate a light bulb.
But that would entail converting all the food eaten by the individual into electricity. In practice, less power would be generated since food is needed by the body. However the scientists say the ‘bio-nano’ generator could be used to run devices embedded in the body, or sugar-fed robots. “
