I was considering only technology presently available. Barring major
technological developments, I don't think it can be done. Keep in mind
that you couldn't just use a "normal" glucose-oxygen fuel cell. It has
to be implantable, so all the materials must be insoluble, hypo-
allergenic, and not cause any local tissue inflammation or damage. It
would somehow have to interface with blood vessels for "fuel", which
would require a material which doesn't cause clotting -- very difficult.
