Well, we're getting closer. CIT has invented a button-sized propane burning fuel cell that can power MP3 players and "flying robots." While I suspect medicinal Mary Jane had something to do with that last possible implementation, the concept is staggering. It's obviously going to take a few more years for this to hit the market — what with the propane and all — but eventually they'll get it so you don't singe your eyebrows while charging your batteries.
