   About 65%-75%

    Think of it as the BTU's of the fuel. Diesel is about 125K BTU or 132 mega
joule. My boiler for a *very* large, poorly insulated house in northern US is
only about 185K BTU -- that engine could easily heat my house and provide just
burning a gallon an hour. And produce about 65KW electric while doing it. Well,
maybe at only a gallon an hour it would be more like 36KW.

   I was thinking awhile ago about building a Tesla turbine to run on the lost
heat of the engine exhaust. Thermoelectric generators would be simpler to
implement tho, like http://www.hi-z.com/websit07.htm
