Peptide super capacitor. Anytime lots of energy is involved kWs (Kilowatt Seconds) lots of potential gremlins dance across the stage like a lineup of the Rockettes.
I'm not saying this is unachievable, but there are going to be LOTS of limitations and caveats with the technology. Energy density is the big question. Stuff too much activity in too little space and the Boeing Dreamliner nightmare enters the equation.
BUT BUT BUT
The computer industry is THE master at handling lots of energy in tiny spaces, with millions upon millions of junctions and energy management.
I hope for the best. I wanna wrist TV so I can watch reruns of Sugarfoot, and 77 Sunset Strip.
