With a spark ignited engine?

And no co-generation? Please pray tell us. I've been at this for decades and I've not seen it.

Please don't come here quoting the usual "sources" of 200 mpg vehicles. I have either seen them work in person or I have built duplicates of them. They do work after a fashion but none double or triple the thermal fuel efficiency of a gasoline spark ignited engine.

The ability to get 50% thermal efficiency from a spark ignited gasoline engine is pretty exceptional. That isn't far behind the efficiency of an ocean going diesel power plant. A few more improvements will put TE closer to 60%. This isn't bogus internet claims. This is just good engineering.
