I thought the idea was to provide an energy source significantly larger than the normal supply of free-floating ATP, so that you could run lots of other nano-gadgets?

All of the more advanced uses of Drextech will give you a serious heat dissipation problem. I've seen energy dissipation figures as high as several hundred kilowatts per cc for the more ambitious devices (fast assembler systems, computers, synthetic muscles, etc.). In particular, medical assembler / dissassembler systems that work significantly faster than normal metabolic functions are going to quickly run into problems.

What kinds of low-power applications are you thinking of?
