LOL - you are basically claiming in a Leaf forum that Leaf isn't viable, as it is now ?! :lol:

It reflects on your critical thinking capabilities than on viability of EVs.

Here is a suggestion for all the Volt proselytizers - first broaden your minds and find out how Leaf works in real life.
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

The Leaf needs about 20kW to sustain highway use, so a 10kW would easily double your range. 20kW would be about perfect for long trips, and 30kW would allow you to charge and drive, so you could arrive with a full charge. 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.

You think the state and federal government won’t notice, and also won’t care about, that thing you are towing behind you on the freeway?
Just as onerous but still not my problem. Same as I do not worry about smog regulations when renting a car.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.

RAV4 traded in for I-Pace Dec 2018

Phil,
I knew there was a reason that I loved you. :lol: :lol:

Capstone Turbine corporation has a C30 30kW generator (http://www.capstoneturbine.com/prodsol/products/" onclick="window.open(this.href);return false;)
that I have been watching for some time now. I liked the idea of a 1 inch or 2 in receiver in the rear that would incorperate a direct connect to the generator. In your opinion, could such a receiver hold enough weight for this C30 plus fuel for 3 hrs?

Is the Leaf perfect. NO! While I am purchasing a leaf and hope to have it within the month, I know the car will only provide 90% of my driving needs. I can't even go to the airport for a flight on it's current range. Even with QC charging, it would double the time necessary to get to the airport (Atlanta). In order for the BEV to replace ICE, the BEV needs a min 150 mile (interstate) range. That would be 2 hrs driving for every 45 min QC stop. Go to NM see how far the leaf range will take you. I live in middle GA. The leaf will take me to the town north of me (Macon), and south of me (Perry) and that is it. For around Warner Robins, it's great, but that is it.

Even with a good QC intrastructure you would spend as much time recharging as driving. That is not going to hack it here in America. I love the BEV, but the leaf needs to have 4x the range at the same price to become main stream.

It may be possible to "hang" the unit off the back if careful design was done, but the Leaf's rear suspension would probably not like it without some tweaking. So for our initial prototype, it will be a compact trailer.

Another option is to put one of these generators from Home Depot on a trailer. http://www.homedepot.com/webapp/wcs/sto ... oreNum=674" onclick="window.open(this.href);return false; But how would you charge and drive at the same time? Does the car allow it?

Those are garbage not to mention it would be a nightmare to interface to that unit.

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.

A lot of talk about range extending and trailers, but nobody remembers these things?

ICE engine on a trailer, EV turn Serial Hybrid:

Extra battery pack on a trailer (homebrew):

There's a good solution for ya: Rent a range extender. Why lug around an ICE and several gallons of gasoline you'll hope you never use? Bonus: They can be fitted to run on cleaner fuels like propane!

N952JL: That PDF link won't open for me :/ URL looks funny, too... can you link to the page it's linked from?

Ideally, I want one of THESE. But they ignored my queries.
