The most efficient computer would probably be a notebook, although
some notebooks prefer 16V.  Three 6V batteries (18V) would probably
work good.
Don't completely rule out an inverter -- the square wave versions
are very efficient.
You would probably get more replies if;
- you used your real name, or
- put your real name somewhere in the message :)
