I feel totally geeky for saying this, but on this show, one of the rogues said that Neo would have no muscles and been unable to stand. I am not sure that this would be true in the context of the movie. When Morpheus is presenting Neo with the history of the future he says:
"The human generates more bio-electricity than 120-volt battery and over 25,000 BTVs of body heat. Combined with a form of fusion, the machines have found all the energy they would ever need."
Now I am no expert on physiology, but body heat would come from metabolic processes as a base line. However, a body in motion would generate more heat based on a greater expenditure of energy and musculoskeletal friction? (Not sure on this last bit. Think I heard it somewhere.
Therefore, the machines would have an incentive to make sure that Neo and the other batteries did in fact have muscles and more body mass than a paraplegic as mentioned in the show. Otherwise the core premise that the humans were "batteries" would be nullified outright or substantially undercut.
Now, the bigger question I have is, why they would need anything beyond fusion, but I digress.
