1. A fearless rider who doesn't mind having a 6000-psi compressed gas
cylinder in close proximity to his family jewels.

2. A special compressor capable of filling the compact pressure bottle
to 6000 psi.

Not in a motorcycle but a couple of friends did it in trucks. Less dense
then gasoline or diesel and slightly less MPG. Gave up about 1/4 of
their load carrying capacity because the tanks were added in the truck
bed. A bit expensive with new carburetor and tanks. One had trouble with
warm starts, used to leave it idling if he needed to go into a store or
take a lunch break.

Much more suited to fleet use where you can have your own 1,000+ gal
storage tank. Good for warehouse forklift type apps as the exhaust is
fairly clean. I think it is exempt from smog checks in California.

One said he only made his money back by 'cheating.' Avoided paying road
taxes by filling up with fuel that was not meant to go into cars/trucks.
I think he also went 100k between oil changes because it burned so
clean. He eventually gave the truck away when he got tired of the
hassles and bought a conventional gas truck.

Only partially correct. The problem is NOT the saftey of the tank but
rather the shape. Currently I'm only aware of cylindrical tanks being
made. None mountable in an aceptable manner. 8^( There was a company
in england attempting to make tanks that are usable on a motorcycle.

OK, so what pressure does the station deliver the CNG to your tank?

And what does it take, about ten gallons of CNG to go 200 miles?

That's a rather inconvenient cylindrical tank to be straddling...

I've never heard data on how far you can go on a CNG fuel motorcycle.
I to would like to know.

They were working on shapes more plauable to motorcycle usage for just
the reason you gave. It's an akward problem to be sure. I know I don't
have the answers. But I'm sure there is somebody or some corporation
out there that can do it. The question then is WILL they do it. I
think it would be interesting to see if they work it out. Until then
we'll have to settle for gas, diesel, electric or steam.

It's interesting that you're buying CNG the same way
you can buy propane. A neighbor was happily running
a CNG Honda as a commute vehicle and refueling it
at a local filling station in the bay area.

Apparantly $5-6 grand gets you a home refueling
station if you want it.

http://www.newsweek.com/id/154709/output/print

My understanding is that by volume, a gallon of CNG
gives you roughly 70% of the energy of a gallon of
gasoline.

Any gaseous fuel will run way cleaner than gasoline or
diesel. I put 12,000 hours on a propane powered genset
that was still running strong on the original valves and
rings when we sold the house. No contamination of
the oil or washing it off the cylinder walls. The used oil
comes out clean but somewhat thicker on oil changes.

We had two propane-powered Cushman three-wheelers to get around the
wastewater treatment plant. They would only be driven 2 or 3 miles a
day and it seems to me like we were only getting about 100 miles on a
5-gallon tank of LPG.

So you would need 7.5 gallons of LNG to equal the range of 5 gallons

Most people recover from their military experience after twenty years

war stories
after only about one year back home.

Depends. A truck diesel, running with a cat and a CRT, actually emits
less NOX, CO2 and even particulate matter than a gas truck running
without.

I've driven both diesel and gas powered heavy trucks. fascinating. The
gas powered trucks run a lot smoother. Range is the crucial problem with
them.

Well actually, when I spoke of "cleaner" I was thinking of
mostly of oil and internal engine contaminants, though
I would have expected good emissions as well. I
really like the lack of oil contaminents.

And when you speak of "gas", this is CNG or propane or
"gas" as American for gasoline ?

NOX and CO2 would seem to be pretty much a given for
any ICE, though you might expect less CO2 and more H2O
for CNG.

Lower particulates seems surprising.

How about hydrocarbons ?

My current gasoline tank is 6.5 gallons and I'd like larger.
MPG, range and tank size is a legitimate criticism though.

That was pretty much my thought, though I think
I'd want the safety valve pointing somewhere other
than at my crotch. If nothing else, flash frostbite
on the family jewels sounds very unpleasant.

A gasoline tank can catch fire if there's a leak onto the hot exhaust
pipes, but it won't go BLEVE on you.

I never made any speculation but I do think it is safe to say that if
mountes like many gasoline tanks (inside the perimeter of the frame)
the risk would be no greater. But that's mere speculation on my part.
I suggest you ask someone who has done the research.

I do find you question valid and you bring a good point...but I doubt
if anybody has researched the matter without bias against motorcycles.

p.s. you will excuse me for pissing off krusty. It's easy to do.

A gasoline tank can catch fire if there's a leak onto the hot exhaust
pipes, but it won't go BLEVE on you.

I have seen crashes on the race track where five motorcycles were down
and two of the gas tanks came off and tumbled down the track in
flames. I also saw a crash where the clipon handlebar managed to
puncture the gas tank, spilling all the fuel onto the exhaust header.

But a BLEVE is something else. A BLEVE produces a fireball that rises
way up in the air.

After the arson investigator interrogated me to do with my car going up
in flames, but not in a BLEVE, and after being a little panicked, I had
warned bystanders away from a possible gasoline explosion, he told me
that tire explosions are much more frequent than gasoline tank ones.

Unburnt? Lower.

It surprised me as well. It was one reason why gas-powered trucks didn't
take off here. They started building 'em, and they were nice and clean,
and then CR diesel engines, ultra low sulphur diesel, and the invention
of the CRT all came at the same time.

I was working for the biggest road haulage organisation in the country
at the time: the Freight Transport Association. It surprised them as
well, but the tests showed it was true, and gas truck just faded away.

The only area where gas trucks stilll really score is noise: they're
definitely quieter.

But if it really is CNG (and not LPG or such), it is stored as a gas and
not as a liquid. Not that a 200 bar tank blowing up is anything I would
like to be close to, though.
I would also worry about crash damage to the high-pressure vessel and its
fittings.

I wouldn't. Gas storage and transport really is incredibly safe. The
vessels are incredibly tough: the fittings are designed so that if
they're severed, leaks are cut off, etc etc. Just consider how much
bottled gas is moved around the world by road already. Accidents are
very rare.

You're bound to get more accidents as gas engines are more widely
used, but I'd say that the present high pressure petrol or diesel
fuel systems arguably offer a greater risk. Look at the way vehicle
fires seem more prevalent (no, I have no stats to prove either way)
since the universal adoption of FI rather than carbs.

I'd certainly be interested to see vehicle fire stats figures, if
anyone's got any.

Point taken. I was thinking of the 200 bar cylinders we handle in the
lab. Apparently these make excellent projectiles if the main valve
breaks off, but I assume anything made for a motorcycle would have
rather different safety features.

A nationwide bottled gas company had an acetylene storage facility in
Kansas City.

Over the years, most of the neighborhood became residential, but the
junkyard-looking acetylene storage facility continued in operation
until one day an acetylene bottle leaked, the gas was ignited, the
ensuing fire heated other acetylene bottles and they started
exploding.

The bottled gas company wanted to rebuild their facility after the
inferno, but were denied a permit...

The range of a CNG-fueled vehicle has not been discussed yet, but I
suppose the gas cylinder would weigh more than the gas it contained.

Can you imagine riding a motorcycle with a 10-gallon, 75-pound gas
cylinder mounted in the convential position?

Nope, I didn't learn about BLEVE's from Wikipedia. BLEVE's were a
topic in my firefighter training at the oil refinery.

You suppose wrong. Try humping empty and full hot air balloon gas
cylinders around: you soon appreciate the difference.

It's been discussed elsewhere. I've said: the problem with gas-fuelled
vehicles is the relatively limited range. Gas conversions - CNG or LPG
- ar quite common in Britain, chiefly to things like V8 powered Range
Rovers which (a) have the interior space for the fuel tank and (b)
cost a fortune to run on pump petrol. Most of these (if not all) are
duel-fuel: the gas tank is an extra installation.

Quite a few motorcycles mount their fuel tanks elsewhere. It would be
interesting to see what designs would come out from a gas-fuelled POV,
though. For example, you could store gas inside the frame....

Heh. Memo to self: CNG, LPG, CNG, LPG. A CNG tank is indeed likely to
be heavier.

We are in agreement that tires blow first. What I saw was a gas fire
that acted like a BLEVE. It was weird to be sure. The owner over filed
his chopper after a long ride on a hot day. Apparently when the fuel
got boiling hard it was putting out enough vapor to cause a BLEVE.
Didn't take out the gas station but the pump got crispy enough to need
replacement. But that was 1984 and the details are hazy.

What, do you feel like your naive ideas are being undermined?

If there was a worthwhile market for CNG-fueled Old Wings, there would
be a plethora of conversion kits on the web.

Found this URL for CRT-diesel vs. CNG busses.

http://www.dieselnet.com/news/2002/04carb2.php

They confirm much of what you say but assert
higher NO2 and NOX for diesel.

You'd expect lower CO2 emissions for CNG just
because of the ratio of hydrogens and carbons
in the two fuels, but I haven't tried to work the math
to confirm this.

Not picking on you, just using your post as an excuse to rank.

While this isn't in range of your thought or intent, lucky we don't have
kings in the USA and even more so that I am not him.

The problem in the USA with range is about our class system. The nouveau
riche want private neighborhoods with out having to associate with the
lower classes. I would use Stanford Industrial Park/Palo Alto as a good
example. A starter home, 2 bedroom 2 bath, maybe 1200^2' will go for
over a million dollars. Same house in a commuter city 30-50 miles away
would sell for maybe $240k. Typically each company will have the top 10
or 20 managers living within walking distance of the company while
700-1,000 employees will have to commute ~60 miles a day. You could cut
our energy usage in spots by 30-100x just by getting rid of this crazy
situation. There is nothing else on the table that will reduce energy
usage by 98%. There is nothing else on the table that will make
alternative fuels viable like reducing the range. Heck, lead acid
batteries are good'nuff for 3 miles in a golf cart.

You could solve all the problems with short range alternate fuel
vehicles and huge consumption of energy with one edict: Just like
businesses have to provide enough parking at their facility, they have
to have nearby affordable housing. The rich could still have their
elitist communities, just not right next to a university and high tech
industrial park.

This isn't a new proposal. I remember the Sierra Club proposed something
like this back in the 1960s. I would be happy to commute with something
using one of those 15hp E-tek motor or a pint of CNG, I just don't want
to do it for 50 miles.

Even if you stick with the current status quo, there is no integration
of commuting and mass transit. By that I mean things like feeder routes
and schedules are not tied to other transport like rail. It even gets
down to an unfriendly environment. For 6 months I used nothing but
public transportation to work during the first big energy crisis back in
the 1970s. I think during those 6 months I had 5-7 bicycles stolen. DOH!
Doesn't the parking lot attendant get the least bit suspicious when a
bunch of thugs pile out of a van with bolt cutters and start clipping
chains and loading bikes into the van? I went from paying $100/month in
gas to paying $100/month for public transit plus losing $100/month worth
of bicycles! Who is going to leave their freaking $5,000 Segway at the
train depot if they lose one a month?

No it just means nobody has tried. There are supercharger kits
available and all sorts of other goodies, like real brakes.

Part of the problem I think is fractured jurisdictions. In the bay
area, there are multiple counties which voluntarily participate
in BART. I am absolutely amazed that Santa Clara county has
paid into BART but you still can't take a BART ride up the
penninsula to San Francisco. Eventually, you may be able to
get there by way of a long detour through the east bay
and Oakland. Even within the county, there are glaring
problems getting to the airport.

Two more of my favorite crackpot solutions:

More telecommuting. Why bother to leave home ?

Multi-passenger van sized jitneys. San Francisco
used to run these down Mission street and they were
way quicker than Muni at a competetive price. I've
also seen similar in Mexico City.

There is a natural gas pump across the street from my job. A couple of
months ago a guy was filling up and his work van's fuel tank burst at
the seam and then ignited for a few seconds.
I ran out to see what the noise was and this guy was staggering towards
me with his jeans torn to shreds (like a demin hula skirt.) and his hair
all burned off.

At least with gasoline, when you overfill the tank, it just runs out on
your Reeboks.
