Jan, I agree with you that sometimes diesel might be a great choice. What some
people fail to recognize is that bio diesel can be fairly simply made in your
garage. Yes, one can have a windmill on the roof or some other complicated
scheme that is the ne + ultra but sometimes the simplest most effective
solution is the best "for a given situation". Many years ago when I was
working with a Twike project I found it very enlightening that this really
cool, highly over-engineered over built and overpriced EV used 2 $15 unmodified
Braun hot combs as the defroster/heater. They ran fine on DC pack voltage just
couldn't use the OEM switch to turn them off and on. I don't remember if they
had a contactor or one just plugged them in, what I do remember was how well
they worked on a rainy cold blustery day at Alameda! Would they work in
Minnesota in the dead of winter in a full sized car? Maybe as defrosters but
definitely not as heaters. In that case I have a couple of helicopter cabin
heaters that I might consider using, LOL. Don't weigh much and put out quite a
bit of heat and one could probably find a use for the exhaust flame. Keep on
truckin, Dach.

I have been following the heater thread and since I have that Webasco diesel
fired heater in my G-van just out of curiosity checked what they cost. Holy
cannolis!! 2500-5000? Even on Ebay they are bringing some big time money. I may
have to do a surgical removal on that puppy. While I was digging around under
the engine (now controller) cover I reacquainted myself with the cool GM
accessory drive setup for the alternator/ AC / PS/ PB. Hmm, a very tasty
looking large DC motor driving all those loads indeed..LOL, may have to start
considering parting this thing out. Dach.

What I forgot to mention is that I make my own biodiesel from waste vegetable
oil.
Still, diesel has the highest energy density of common liquid fuels, and can be
burned very cleanly, especially in external combustion situations. The Webasto
website says their hydronic heaters are 97% efficient! The carbon impact of
diesel is arguably less than that of LPG, which has a lot less energy content,
and which requires a lot more processing.
Diesel heat is also arguably less polluting than electric heat powered by a
coal generating station, probably by a LONG SHOT, since the hydronic diesel
heat is 90+% efficient, and the coal is at best 30% efficient by the time it
gets turned into electricity.
