[ausev] Series hybrids

[Roy Holder]

To keep the emissions low I was looking at DC marine diesel generators.
They typically have a longer run life and reliability, and in the case of
the Ossa, are lighter. 
The Ossa have capacities of 6, 13.5, 25, 50, 100, 150 and 200kW.
13.5 and 25kw  were the 2 sizes I was interested in.
I called and talked to an engineer and talked about the 25kw system.  It's
less than 600 lbs and it consumed 1.3 gallons per hour at full load.  They
could tweak the output voltage to match need with very little loss of
efficiency.  It would run well on biodiesel and they had supposedly tested
with biodiesel a lot, and is was VERY low emissions.
The down side is they cost more. I think they said a generator was about
$10,000
