Hi Joe,
I a dutch newsgroup my attention was drawn to a
fuel-cell. Take a look at
http://www.max-power.com/fuelcell/
It makes running the engine for charging obsolete and
it's capable of running a modern low-pressure
watermaker, silently.....!
On the other hand it is costly and poses the need for
another tyoe of fuel (I found a price of USD 0.95/Gal
somewhere for methanol).
But it's another, elegant way of getting power when
you need it.
Regards,
Janna&Len
