My bio-diesel buddies claim diesels cause less pollution than comparable gas car exhaust; I'll have to question them more carefully about that.

"Particulate polution" counts all particles in the air, including pollen, dust, etc. I'm not sure what percentage these things account for, although I'm assuming it varies greatly from area to area. I know my town in the hills is considered highly poluted by particulate scales in the spring because trees and flowers are dumping large quantities of yellow pollen all over the place, however polution because of cars and the etc. is almost non-existent.

As for normal diesel (not sure about bio specifically), it depends on what type of pollution you are counting. I is much better for the ozone than what we put in cars, however, it is carcinagenic soot, which is horrible for us to breath, not to mention it makes the visible air pollution we think of.

I think a lot of controversy in statistics over air pollution come from the over-generalization of what it is. what I was trying to say about 2 cycle engines was that using them for any ammount of time was much worse than driving a car. In terms of getting the average American to change their lifestyle, I think it would be easier to get them to ditch a lawnmower than a car. And it's definetly more productive than some of the statewide plans I've heard. A few years ago in California, they were debating on whether or not to ban asthma inhalers because of the aerosol. Yeah, that stuff is bad news, but I think there are more productive ways of debating clean air policy than taking away what was then the only effective way to keep people from having potentially deadly attacks...

Greetings,

Does anyone know of any detailed analyses of what would be
modern, sustainable self-sufficient diets in various rich regions of
the world? For example, if the UK decided to minimise the national
food miles, and eat only UK-grown food, grown sustainably, could we do
it? Would we have to become largely vegetarian or vegan to feed
ourselves - I believe that soy, most rice, and many pulses are not
suitable to grow in the UK, and if so, how would we replace them in a
vegan diet?

(BTW I'm sure we could make a case for continuing to import
small quantities of low volume, high added value luxuries via sea
freight, such as Fairtrade chocolate :-)

Thanks in advance for pointers!

Amanda in the UK

The Portable Power Equipment Manufacturers claim that less than 1% of
California's air pollution comes from 2-cycle engines (mowers, etc).

The American Lung Assn http://www.lungusa.org/air/airout00_diesel.html
says diesels account for 26% of all particulate pollution from fuel in
the air, so that leaves 3/4 of all particulates coming from other
fuels; diesel is hardly the main culprit. My bio-diesel buddies claim
diesels cause less pollution than comparable gas car exhaust; I'll have
to question them more carefully about that.

The Toyota Prius uses nickel/metal hydride batteries, which are not
regarded as hazardous waste when damaged (nickel is pretty inert, or
our food cans would kill us). I don't know offhand what some of the
other hybrids are using, but I believe they are not lead-acid or other
toxic combinations. Also, batteries in hybrids are far smaller than in
all-electric cars. And sure, they wear out in 10 years or so, but the
many thousands of pounds of pollution that is saved more than makes up
for the few pounds of battery core (most of which is recycled, anyway).

What's this "six block evacuation" after an electric vehicle crash? I'd
like to know more about that. Sounds like an oil lobbyist's dream.

I think it's important to check facts and to be cautious in condemning
attempts to improve the environment. Nothing we do will be perfect, but
I'd rather see us take small steps toward sustainability and support
them, rather than criticize the efforts of others and wait for the
giant leap to perfection that will never happen.

Toby

...not to mention that it's hard to find an *automobile* that lasts ten years without having to have many of its major pieces replaced. Is a battery set any harder to recycle than a dead engine or transmission?

Loren,
who hasn't quite managed to get a Toyota to last ten years, but who feels they last longer than darn near anything else on the road

We are all going to have to get used to getting along with a lot less
energy in the future, and the time to learn of course is now. It's
taken us going on four years, but we are finally learning how to stay
comfortable during Oklahoma summers without air conditioning. So I
figure if we can do that, I can also learn how to live and work without
an automobile. It's a challenge of course, but I'd rather figure that
out now rather than later.

Aloha,

While we're throwing stats on cars, a fun one is that more pollution is
created in manufacturing a new car than will ever come out its tailpipe
during its useful lifetime. Thus older, well-maintained fuel-efficient
cars may amortize out as least polluting overall.

The 1980's was about as good as it got for this - emissions controls
weren't so good before that, and mileage has gone downhill since then.
IMO overall quality of product was better then too.

I'm curious to see if shared vehicle systems (such as flexcar,
www.flexcar.com, which is operating here in Seattle) will reduce either or
both of pollution and traffic.

If I can walk, bike or mass-transit easily to all the basics of daily
life, I only use a car for longer trips, vacations, occasional
hauling/transport needs, etc. So cluster villages and other more communal
'all-in-one' community designs would seem to support similar behavior.

They are the manufacturer's lobby, of course...grain 'o salt and all
that...but even if they're bending the stats considerably it is still a
very small percentage of total pollution.

On the *other* hand - 2-cycle engines spit out *way* more unburned
petroleum (gas and oil) in their exhaust than 4-cycle. One sample of
stats:

"The 2-cycle engines used in snow machines emit 20 to 33 percent of their
fuel unburned. This emission includes lubrication oil, which ismixed in
the fuel at a ratio of 50 parts gasoline toone part lube oil (50:1). Most
of the visible haze in 2-cycle exhaust is from the lube oil."

This is typical for any 2-cycle, from little weedwhackers to jet skis,
dirt bikes and snowmobiles. 20-33% raw fuel!! :-O

I have read, and been told by biodiesel advocates, that the particularly
nasty particulates present in petroleum diesel are simply not present in
biodiesel exhaust, because they're a result of the petroleum chemistry and
don't get created when burning biodiesel. Biodiesel exhaust certainly
doesn't stink or make me feel nauseous the way petro-diesel exhaust
does...

"Diesel" is after all the name of the guy who invented that particular
form of internal combustion engine and doesn't say anything about the
chemistry and byproducts of whatever fuels will make that kind of engine
run...
