Is there any experimental technology in the works for getting chemical power from human blood? I ask this because it seems like the best way to power a prosthetic limb would be to tap the body itself. That way a person could just power that limb the same way as all his other parts. With food and oxygen.
What aspects would have to be addressed? I can think of:
-How do you actually convert the stored energy in blood to usable energy for the limb? And without poisoning the blood with waste products?
-Can it be done efficiently enough that it doesn’t use up too much food and O2? Otherwise, the person would slowly starve and/or asphixiate when the device started using up all the energy.
What else am I missing?
