Why Electric Motors Are 3X - 4X More Efficient Than Internal Combustion

Diesel puts out more and exactly where you don't want it.

Check with The Trucker but I understand that semi-rigs will soon be required to be retrofitted with cat converters like cars ~ $10,000.

California just prohibited ships from burning of cost effective bunker oil within 25 miles of the coast.

Some cancers were 500 times more prevalent near Long Beach than the inland deserts.

I meant to say that. Really.

Before people "fix" gasoline-powered cars, which don't need fixing, they should do something about diesels. Diesels are a serious pollution problem.

And those coal plants in China.

None. It was to show that O2 cannot be considered a pollutant, since it does not 'endanger public health or welfare' (to use the Supreme Court definition) until we change the concentration very significantly.

For trucks it is a question of filters and not a question of catalysts. The particulates can be filtered out.

Same deal. Particulates can be filtered.

France is merely part of a large continent so it imports pollution from the surrounding countries but I wouldn't be surprised if thier air IS cleaner than the average.

Considering it came from Rob Dekker, that's hardly surprising ! Maybe he ought to learn about the carbon cycle ?

I'm glad you have such faith in the courts.

That means Gore's film DOES contain lies and errors as determined by a British Court.

Diesel particulates emissions is already being increasingly regulated successfully in the EU.

Graham

In the EU, diesel cars now have cats and some at least have special particulates traps which burn them off harmlessly AIUI from time to time. We have the advantage too that we switched to 'clean diesel' some time ago, a process that is only now taking place in the USA. Plus vehicle diesel engine design in Europe has become highly advanced. Even 20 years ago I drove a mid-compact Peugeot with a 1.9 litre turbo diesel engine and it was quick. No slugggish acceleration either.

Couldn't agree more.

Bare faced lie.

That's not nice Graham. There is no reason for your statement.

Don't get me started. I've had discussions with global warming deniers many times about all aspects of the subject. It has been a big waste of my time. Even hard data gets denied or twisted, similar to how evolution deniers deny data or twist it.

Thank you. I'm done.

Graham

internal combustion engines have that unfortunate torque curve which forces you to have a much bigger than necessary engine to compensate for the fact that torque drops at stall instead of increasing. that wouldn't be much of a problem for IC engines running at constant speed, even for longhaul highway driving, but for what most of us do with our cars, it's less than optimal.

Nobody ever thinks about what happens when we run out of electrons. We may have passed peak electrons already.

Which reminds me: "Johnny, do photons have mass?" "How should I know, teacher, I didn't even know they were Catholic"

Little known fact; efficiency of electrical generation is currently half of what it was in Edison's day. Well, it's a trick question, though; Edison was businessman enough to sell off the heat as a byproduct (isn't that what they call cogeneration?) but today utilities, as monopolies, are too lazy too chase that efficiency/cash. too bad for all of us.

Los Angeles then. Modern cars, strictest emission standards in the world, and no coal fired power plants in the area : "Los Angeles Most Polluted US City, According To American Lung Association Report"

Do you want me to continue ?

Face it dude : The ICE is responsible for the majority of air pollution in all cities around the world.

Far dirtier than electricity generation, no matter by which means that is generated. Possible exception are the old coal fired power plants, but only for SO2 and particulates. And it's time these dirty plants get cleaned up too, and they will. The UK seems to have the biggest, dirtiest coal plants with major problems with particulates. Is that why you prefer your Saab with air filter system over EVs ?

If so, then we are talking at different levels. Here in California, "environmental impact studies" deal with issues like "is it environmentally acceptable to have high-voltage wires running through the desert (nature preserve), to reach solar power that are going to be built." That's at a different level than filtering SO2 from coal power plants.
