Since Reciprocating = Maintenance Your best choice in a prime mover APU engine on the used for cheap aftermarket is a : capstone c30 air bearing turbine engine with high efficiency waste heat recouperator.

Capstone Micro Turbine Natural Gas to Electric Generator Model 330-30 | eBay

Rated for 25,000 hours of nonstop continuous full power delivery of 30 kW or 40 HP, between inspections. The capstone could power your Nissan leaf at over 80 MPH continuously down the freeway for over 3,000,000 miles! And not one drop of messy lubricating oil or gross oil filters ever need be changed!

Though you will go through many tires, several CV axles, and a barrel of bug juice....

IMHO this type of prime mover is the only that should be allocated resources and materials to be produced globally.

Now with the transmission difficulties of efficiently coupling 100,000 RPM to the road solved by the advent of the electric power train, and both now available cheap on the aftermarket; it would be the choicest persuit of any serious ecomodder.

We need a topic in our forum full of case studies of ecomodder built turbine electric hybrids.

Wrightspeed Announces Super Clean Garbage Trucks | Wrightspeed Powertrains

If garbage trucks can see such vastly improved fuel economy, imaging what us ecomodder will do!

Even now Nissan leaf and even tesla power train parts are hitting the cheap used aftermarket on ebay for us to start building with.

If interested I have a c30 turbine APU engine without grid tie circuitry and cabinet for such a build I could part with for $3500. Just PM me.

Ya. I've thought about doing an air cooled VW engine. But in order to get better emissions I was thinking either using such an engine with either a turbo charged or large displacement with a high compression ratio and a very low air to fuel ratio (30:1) running on propane.

Yes. Yes it would.

What are the dimensions of the APU?

Forget what I said about the Tesla roof tiles; they are less efficient. But they do have an interesting clip-together circuitry. The new 14.5 Kwh Powerwall instead?

The Dunn-Wright is a 2-cylinder 4-cycle engine and a 2-cylinder 2-cycle compressor. I was thinking of a utility power trailer, that could provide electricity, compressed air and propane, and would be useful parked at home.

Now it wouldn't make sense to get to carried away with a pusher trailer. After all, it would only be for occasional use, and it would only have to put out a near average power.

A 20hp Honda or Kohler V-twin engine chained directly to the wheels would work. The problem I find with such a system are the emissions. The Leaf is considered a zero emissions car (although we know that isn't true.) So it would make sense to me to put on an engine that gets at least ok emissions. Maybe a propane engine with water injection and a catalytic converter would do the trick??

.
They claim 90% efficiency. But the best dual cycle grid scale turbine plants are very happy to boast 65%. Still that would be far better than any hybrid ice drivetrain.

It would be a major headache to implement - maybe do it up similar to how ZipCar does their subscription service? - but a range extending pusher trailer for things like Leafs that could be shared around among the local Leaf community would be smart. That would put the investment to work better.

I don't have an answer for the emissions statements except to recommend the best engine you could possibly install along with the simplest possible drivetrain to minimize losses - chain direct to the drive wheel, I guess. And shape the trailer for whatever aero advantage it could provide.

An electric vehicle doesn't need a pusher. Just and electrical cord.

Yes. All electric would be ideal. But to get to Denver I'd have to cross the continental divide 3 times and climb mountains up to 11,500ft and down to 5,000ft. Some stretches there's no place to plug in until I'd be barely there on one bar, if I don't use AC or heat and drive like my grandpa. So about once a month I'll have to take the 1985 Golf with its black smoke cloud.

Now if I had an extension cord and a range extending battery/solar panel or the like, perhaps mounted on a trailer, that would be ideal. An aluminum air battery would be great! But if a battery costs the same as another car...

Uhhh? I meant from the generator/ trailer to the car. The trailer doesn't have to push an electric car. Just plug in. As long as we are off in dream land.
