I think you better go back to old proven technology of VW beetle. I have this heater and use in garage sometimes. Back 20 years ago when I convert golf car to the street and build the cabin I was using this one. This little unit spills hell hot air and bas consumption is almost none. You can install it in the trunk -exhaust pipe down through trunk floor. Unit can buy on ebay or brand new generation : http://www.eberspacher.com/products/hea ... ducts.html here is pic of mine:

Obviously you're not talking about the OEM beetle heating "technology" :P

Ah, fond memories of patching salt-eaten heat exchangers with baling wire and aluminum pizza pans -- to great success! It would actually clear the windows after about 90 minutes of operation.

On the other hand it was nice to have a vehicle that you could generally keep running with a few hand tools and things you could find on the side of the road.
I noticed you're still working with polymers.

Maybe a bit of KISS is needed. Something more like this: http://www.trueactivist.com/how-to-easi ... ea-lights/ Do you think that could add a lot of range while still keeping you warm?

This is a very good idea. I actually thought about it since the cold season began last year (2013). I bought a cheap 12v heater from Harbor Freight and powered it with my portable 18 ah 12v jumpstart battery. It actually worked quite well as a space heater when used very close to my body during fall. During one test it ran for more than two hours. I assume the load was small for the battery. It can defrost only a small circle on the windshield since it's airflow from the tiny fan is very low. It's heat is insufficient in frigid winter. This was just an experiment.

My real goal (which I haven't tried yet) is to use my 120v Vornado room circulation heater which comes with it's own thermostat, powered by my huge 55 Ah Wagan 2546 Solar e Power Cube 1500. It comes with 2 AC outlets, inbuilt-circuit breakers, 1500w (3600w Peak) inverter...more specs in the Wagan link below.

With the limited range that current 24 Kwh LEAFs offer, I think any type of heating that doesn't use energy from the battery pack is helpful. I almost never used my 2012's (non-heat-pump) heater during this very cold winter this year because the range had already dropped a lot due to the cold. The WAGAN Solar e-Power Cube is very heavy at about 100 pounds but its still less than an average adult's weight and the LEAF is designed to carry 4-5 adults. So the battery's weight shouldn't be a problem. The Vornado heats a small room within a few minutes and it circulates air very quickly. So heating a car's cabin shouldn't take long.

Even using the Vornado on the lower heat setting, you wouldn't get more than 15 minutes' worth of heat before you damaged the battery. I suggest you look at the 200 watt heaters I used - two of them should work well, while only drawing 400 watts. I's also suggest a battery with at least a 75AH capacity. The solar panels would be much help here. My tests indicated that one heater mounted in the footwell, plus one up on the dash (secured!) would provide enough 'personal heat' for comfort in most temps. Two heaters in the footwell would also work well if only your legs and feet get cold

I haven't tried this yet, since we got our car in March and it was getting warmer out. I was going to use one of these "foot warmers" http://www.amazon.com/Cozy-Products-FW- ... B000079896 and use it as the drivers side floor mat and an old 105 ah deep cycle battery and an inverter. I noticed my feet were the coldest driving when it was still cold out, love the seats and steering wheel :)

I have one of these at work under my desk, and it works great, not sure how much it will help in the car for the legs, but if my feet are warmer, it can't be worse. I was also thinking of turning it on an hour or so before we leave as it cycles itself on and off as necessary once up to temp.

I use the old fan-forced version, and while the heat may be just enough, I'd be concerned about pedal interference...

The foot warmer I have is thinner (max 1/3 inch) than the floor mats I have in there now, but I will be sure to make sure it won't bother the travel on any of the pedals.

How does that model work? Radiant heat? If so I suspect it won't suffice because of drafts.

Yes it is like a heating pad in cased in rubber like material, it pulls 90 watts cold. Yes draft's or air moving is going to move the heat around and at only 90w won't throw off much heat, but it should melt snow in the foot well :)

My second thought was a similar 300w 12v (25 amps) heater to avoid the inverter but I am not sure how to mount it down by the foot-well.
