High Efficiency APU

Hello,

I'm looking for a high efficiency Aux Power Unit. I'm actually
building a electric car, and want some way to recharge besides plugging
in. I'd like to go with a microturbine/turbine for both space and
efficiency concerns. I'm looking for anything over 30 kW of power,
with efficiency being my main concern. Gas stations havent started
stocking Jet-A, so I guess you can add that to the list of
requirements.

I'll probably be using my own alternator/generator, a secondary 40kW
unit, but I couldnt complain too much if the unit came with one.

Any sort of links at all would be really useful. You guys are really
the only domain I know of that might be able to help with something
like this. Even links to other good message boards would be great. I
really appreciate it!

Thanks mates,
McCoy.
