If you fill a vessel with only H2 and O2 and ignite it, the product is water and
heat. If you fill a vessel with H2 and air and ignite it, the H2 and O2 will
combine to form water and heat. The heat of combustion will then cause the N2
in the air to combine with the O2 to form oxides of nitrogen. That is a
I doubt you'll find any plans. The most practical way to power a car by
burning wood I can think of would we an electric car charged by a
stationary steam powered generator. You could be driving on one set of
batteries while another is being charged. For direct burning of wood
you might be able to use a steam or Stirling cycle engine, but you'd
have the problem how to stoke the engine while driving, problems with
starting and stopping it for typical practical trips, and problems
controlling emissions. Small steam engines don't seem to be
commercially available (I've looked for solar projects) and making
your own that's reliable would be a major engineering and machining

Years ago I knew a fellow who heated his home with wood and was proud
I asked about how many hours it took his family for all the work vs the

The look on his face was priceless...........
You left out the opportunity cost of the exercise vs. no exercise
vs. paying for membership in a club vs. buying home equipment.

Value of being able to cook and stay warm during 4 days without any

Back in the days when fuel oil was $0.17 a gallon, I can see that
working out. Nowadays, I doubt that very much, unless he was in
absolutely lousy physical condition. Wood is my primary heat source,
and I don't spend much time putting up wood. Three or four days a year
is all, call it a couple weekends, and my labor is tax free. The
payback is worth several hundred dollars, plus tax. That's pretty good

I consider a chainsaw a must out in the boonies, so I won't include that
cost. It's both needed in an emergency and to keep the downed trees cleared
First is the wood availability. I might get a 1/4 of my needed wood off my
own property. The rest needs to be scrounged up. Locals seem to do well
cleaning up slash piles from the local timber companies as long as they stay
on their good side. That is usually free as long as you make things better
when you leave then when you got there. Done right, I won't pay for that
Where the cost is a problem is in the stove and installation. A DEQ
qualifying stove is $1800 to $2200 for my size house. Figure another $400
to $500 for a stainless triple wall stovepipe. Install I could do myself.
At least a few hundred more for a hearth and sundry other items. Since the
house already has a heat pump and I would keep it as backup, this means all
the money is against the cost of wood. My insurance is OK with a wood
stove, but it would add $200 a year - if it was inspected by them and done
right. I figure I'm going to add one of the outdoor stoves if I'm going to
do it. This won't add anything to my insurance if it's more than 10 feet
from the house. Plus I can feed it big wood cutting the labor.
Since my total heat bill for the winter is $400 to $600, that's a while to
I piddle around with it about 1 trip every week during the summer/fall.
If I counted only the cost of labor, it would be a losing proposition.
But there are the health benefits, the enjoyment of being out there in
nature, the money saved by not doing something else for recreation,
etc. The cost of a club membership to get the same excercise would be
considerable by itself.
Yep, I could make more money clerking a gas station for example but
would be totally bored doing it and would hate every minute.
Not too many as far as I can tell. I don't see a lot of woodpiles
in the yards. I think wood burning stoves make insurance companies
nervous. Propane and natural gas are probably the most common in my
One of the local farm stores started selling corn burning stoves last
year. I've thought about it. I don't know if it would be allowed in my
neighborhood due to the storage.
Nervous? Nervous!!! Gives 'em palpitations at the mere thought that
they might have to pay out a claim. Just ask the people in the areas
of Queens and Long Island who are getting their homeowners insurance
canceled on the chance that sometime in the next 10 years or so a

Coal was more commonly used here (than wood) until the natural gas

there was a shortage of pellets and the price doubled. It might be a
different story if wood was the primary heat source, but my insurance
company is ok with wood stoves.
My company was fine with it but only after doing a very thorough
examination of the installation. I have seen a few that the insurance
isn't going to pay off on if they ever have a fire as they don't come
even close to a safe installation.
They will when your house burns down due to a wood burning stove
problem. At that time they will promptly point out the disclaimer text
of your policy that states that they are not liable for damages caused
by fire started from wood burning stoves. Read the fine print of your
policy, if you heat by stove, and make sure you have the proper
endorsement on your policy to cover fires cause by wood burning stoves.
Your premium will go up, but at least you will be covered.

Don't be so sure. What applies with insurance companies in your
country doesn't apply in mine.
Wood burning heaters are acceptable to insurance companies here
because our country has stingent Standards which must be met at both
the production and installation stage for all wood burning stoves.
They can't be installed by home owners without inspection and approval
by local authorities.
