First, I want to thank everyone for jumping in and helping me out. The glucose fuel cell is a great idea and one I completely forgot that I read in Freitas. Much thanks to Anders, Robert and Eugen for that.
Just to be clear, I'm specifically looking to power a hippocampus prosthesis. Ted Berger at USC has been working on it and in his paper "A Neural Prothesis for Hippocampal Memory Function," he outlines the five essential requirements for an implantable microchip. He covers the first four in depth, but the fifth requirement is power and it's the only requirement he doesn't address at all, leaving me in the lurch, so to speak. I know some of you might read my book someday and the last thing I need is emails saying, "Hey, dug the book, but you completely glossed over the energy issues! Wassup?!" ;-) As noted before, the issue is heat generation near the sensitive brain tissues.
As for putting the numbers to it, you're right. Unfortunately, I'm not the gal. My dyslexia is really bad with numbers and mathematical formulas [and musical notation :-( ], so I leave that to the experts. So I really appreciate your help.
Take care all,
