 As Morpheus explains in The Matrix, the human body does, I guess, conduct, create a significant amount of energy, heat, electricity, which is, again, why it's being used as a power source there. So, too, does our brain. Yeah. And... So, of course, if anybody's seen The Matrix, you remember the scene with Morpheus. He holds up a little Duracell battery, and he basically says, this is what humans are being used as.
