Liquified natural gas has a bit of a problem in car fuel tanks - on
such smaller fuel tanks even with a lot of thermal insulation, rate of
heat inflow from outside into such cold fuel raises its vapor pressure to
great levels. At many times, the temperature will exceed the "critical
tempwerature" - above which liquid of most of LNG's chemical constituency
cannot exist no matter how high the pressure is. How much fuel can one
store in what practical fuel tank if it is gaseous rather than liquid?
Will the fuel pumps at the refueling stations pump the fuel into such
higher pressures at a cost that the market will support? Will these
fuel dispensers be operable by Joe Sixpack, or require a trained
technician to operate?
What is the octane rating of "natural gas" anyway?
I have heard of trucks and seen forklifts running on propane - but that
is easily liquified at ordinary temperatures at fairly reasonable

Here in NoVA I actually have a flex fuel car as my company heaver but
it's never had anything but E10 in it. Can't get 100% gasoline
anymore, but can't get E85 either. I can't remember ever seeing a
fuel station selling E85 in my whole life. I might run a tank through
if I could get it, just to keep everything clean.
Besides, at least as of a couple years ago, growing corn for fuel
ethanol was pretty much a wash in terms of "saving the planet" - most
of the equivalent amounts of fossil fuels that would be replaced by
the ethanol were used in the *production* of the ethanol, and some
studies showed that burning ethanol actually *increased* our
dependence on fossil fuels.
Well, yes, no, absolutely, maybe, and I don't know. In my state, Utah, guys
were changing vehicles to LPG, and claiming all sorts of savings. Charging
quite a bit for the conversion, too. Only problem was that doing it
required approval in advance from the state, and they will only license
vehicles that are LPG from the factory. So, all the owners who had them
retrofitted were hosed, and some of the companies that did the conversions
were in deep doo doo.
Just making a blanket solicitation is ludicrous of you. And a spamming
Some engines are made that run on 6 or 8 cylinders when needed,
but generally chug along on 4 after getting up to speed. Is this mainly
a computer thingy or do the engines have to engineered from scratch for
this? If the first, are there kits available to make the conversion?
This seems the more logical, easier, and probably cheaper approach if
"Even I realized that money was to politicians what the ecalyptus tree is to
koala bears: food, water, shelter and something to crap on."
Cars run fine on CNG compressed natural gas. I have a friend who
convereted both of his vehicles back in 72 just after the first oil
crisis. Vehicles have a little less power but run fine, exhaust is
super clean. and his vehicles are pre computer. They are actually dual
fuel and run on gasoline too with the flick of one switch.
The trouble with oil, we as a nation are shipping our wea;th overseas
to buy oil from people who hate us.
While we ship our jobs overseas to get them done cheap. Is it any
wonder our economy is collapsing?
Look at health care being such a BIG part of our economy. Its
percentage wouldnt be so large if we had more manufacturing.......
if you think our economy is bad now just wait till the terrorists
we will have a full blown depression........

When I left Australia almost 25 years ago, many taxis and other fleet
vehicles had been converted to run on LPG/CNG (with a cylinder in the
trunk), but a large part of the savings was that LPG did not carry the
taxes that gasoline did. I don't know whether it ever came to pass, but
many people predicted that once LPG use became significant heavy taxes
would be imposed on it to match those on gasoline: the roads have to be
paid for somehow.
I have no idea about taxes on LPG in the USA.
We get most of our oil from Canada & Mexico; they don't hate us (well, maybe
some in Mexico...).
There's the story of the fellow who invented a magic box that could "read"
X-Rays. Hospitals would electronically transmit digitized X-Rays to him, his
box would read the X-Ray and send a full report back to the originating
hospital within two hours. For this service, he charged the hospital $40
instead of the $400 charged by a radiologist.
Skeptical, many hospitals had the same X-ray read by this entrepreneur's
service and a staff radiologist. The differences in the two reports were
Many people benefited. The inventor, of course, but also the hospital and
But the radiologists were screwed. They complained.
The state medical board moved to charge the inventor with "Unlicensed
practice of medicine" and felonious moperty. Investigations were held.
Come to find out, there was no "magic box." The businessman was simply
forwarding the digitized X-ray to a radiologist in India who performed HIS
magic and emailed back the result.
The above story is fiction, but it could happen. If it did, how does the
"keep jobs in America" mantra hold up?

Well it is important to note the poster of the "magic box" story.
We have two local hospital systems and both have minimal staff
radiologists during the day and at other times and for routine stuff
their offshore contract radiologists do the work.
Nothing new and has been going on for a long time.
if obama and the democrats hadnt stimulated the economy with all that
overspending we wouldnt have a bad economy today.
it would be a outright depression with unemployment over 20%
