Todd Swearingen so what can be done to bio-diesel to lower the gel
point? I know that adding gasoline to diesel in winter is done by some
to stop diesel gelling in winters lower temperatures.

Keith Todd - my real problem is 'how to make biodiesel without waste
products'. Any fool can make biodiesel. It does'nt seem so easy to deal with
the waste water and glycerine, and as far as I know, nobody seems to have
come up with adequate solutions on the discussion groups. It is important
Lee,
First thing? Utilize alcohols such as isopropanol and isobutyl
rather than methanol. To what degree the process would need to be
altered to achieve high conversion ratios isn't clear, but there
would almost assuredly need to be some alterations.
You could just fractionally distill the

I wouldn't be so sure that any fool can make biodiesel. I've
seen a few who are far better at perfecting their court jesting
skills than those of common sense. But your point is by and large
applicable.
The waste stream that exists with biodiesel manufacture can
easily be resolved, even

I thought so, but I'm still not convinced you can.

not by intelligent diesel owners. the logical choice is kerosene.

Ah, thanks. I guess I should have been more specific. It was a long
day... How do they control the air going into the engine and how is the
air exhausted? Does it operate like a four cycle engine or 2 cycle?

they are very easy on fuel easy to repair and are one the cheapest

Hard to say. Here is a
they don't :-)
technically, a compressed tank of air runs a air motor (steam engine)
connected to the wheels. unfortunately, you can't carry enough air for a
reasonable range, and you waste much more energy compressing the air, than
you get back from it.

4 cycle doesn't make sense if there is no combustion.

looks like they are using a 4 cycle design. sort of a combustion power

I am going to continue to watch their efforts with an open mind. I am
interested to find out what energy efficiency they are able to realize
in converting the air into motion. I am also interested to learn the
energy efficiency of compression. From their web page it would appear
that there is
Thanks, Steve. The table at the link below is especially interesting
since the engine I'm looking at is in fact part of a genset. Do you know
what the meaning of the abbreviations CV and g/CVh are in the context of

It makes sense until you do an energy analysis. Efficient compression
requires the temperature stay the same. In practice this is very much NOT
the case and thus in the real world losses are huge.

Fossil Fuels such as coal and natural gas in power plants, but
petroleum would seem less likely. Very few electricity producing
power plants use petroleum. Hawaii and maybe a few other places.
