Phil,
have you every seen the paper on "Simulation of a Two-Stroke Free-Piston Engine for Electrical Power Generation". This might be smaller, lighter and more fuel eff than the C30.
see (https://inplortal.inl.gov/free%252520pi ... device.pdf" onclick="window.open(this.href);return false;)

A small generator to extend the range of the leaf for the few long range trips I make would be perfect. I could also use it as a stand by generator for the house when the power goes out.

My current 10kW PV system is gride tie and cannot be used for emergcy power.

Keep up the good work. I love your discussions on EVSEs. And when I receive my leaf I might (I only lease mine) be sending in my EVSE for the 120/240 upgrade. I've installed a PowerExpress from SPX with a 40amp breaker and 8 gage wire. That will be more than enough for the current leaf. Even if we go to 6.6kWh charger.

I wish there was a way to attach pictures but I have found that yet.

Tried sending this as a private message but couldn't.
Tried my link and it didn't work. I couldn't see the entire url with my search so try this one instead.

This is what I'm building with a Capstone 30kW turbine. I can run it on CNG or Propane, and it's cleaner than almost any ICE.

The turbine sounds very cool, but...

Cost?

Regulatory approvals required to bring it to the (after) market, and utilize on the road, with a licensed vehicle?

Not saying it can’t (or shouldn't) happen, but towing a trailer is a different concept than a 3 kWh to 10 kWh range extender, integrated into the EREV design. Of course, no one's built that yet, either.
no condition is permanent

The Capstone is CARB-Approved, and as far as I know you don't need "regulatory approval", just a DMV trailer license.

In addition, the trailer will be CHAdeMO capable, so it will be able to Quick-Charge an EV in any location.

You had me at "CHAdeMO capable..."

hmm....30 kWh.

Have you calculated the capitalized cost per kWh, to run on natural gas in a (semi?) fixed location?

Not yet, feel free to if you like! All the needed data is on Capstone's site. Another option is to grid-connect the unit, and use some grid power and some Capstone power so that you can avoid the demand charges.

Right now my design will only be 30kW capable, not the full 50kW the Leaf is able to accept. Still, that should give a 80% charge in under 30 mins, and a full charge in under an hour.

Cool! Does the design also allow charging while driving?

Yes, while connected to the Trailer, there is an "umbilical" cable that connects to the Leaf's battery that allows charging and/or motor operation while underway. Once parked, the CHAdeMO cable can be used to charge other cars.

Hopefully, I will be able to bring this unit to the December 3rd meeting at Google in Mountain View. Nissan's Engineering team will get a look! =)

Here is the PDF for that Capstone C30, 400-480VAC output, looks pretty big.
