OT: diesel fuel: why isn't it cheaper than gasoline?

Main sources: natural gas, coal, biomass, water. Look to the future, bright eyes ...water.

When created through natural gas extraction, yes there are pollutants. When used to power a fuel cell to run an engine, it's only real byproduct is water. Very low pollution all around though when compared to current methods - but it needs to be developed for an efficient mass-scale.

I believe H has the highest energy content by weight of any available fuel and when they can efficiently produce, store, and use it ...it will be alot easier on the enviro than any currently used fuel. Especially when you consider the amount of energy and fuel used to transport oil barrels from overseas (not even including the damage done by spills).

For now. It's like trying to explain the benefits of steam over coal to an

1820's train operator. Give it time.

I do, but I'm not dyslexic.

"Making" ten cents and hour I read as "grossing" ten cents an hour, like what they pay Bangladeshi kids to make Nikes.

Of course he right off little stuff, like the new water heater you bought for your home. God Bless America, ßill O|||||||O mailto: snipped-for-privacy@aol.com

Not that it has got diddly-squat to do with Jeeps, but still I'm curious: Where do they get the hydrogen?

You do know that it takes more energy to make hydrogen from water than you can get out of the hydrogen by converting it back to water, right?

Not that I think that hydrogen-powered vehicles are a bad idea, it is just that an ocean of water isn't likely to be powering your car anytime soon.

Most long haul truckers don't get paid by the hour but by the mile. In cost-adjusted dollars is diesel more expensive than it was before the Mercedes diesels?

Because of Supply and Demand. The refiners keep the supply low in order to keep prices high. Why would they make a gallon and sell it for a dollar when they can make a half-gallon and sell it for two dollars?

That was my point before, it looked like you wrote 10 cents an hour instead of 10 cents a mile...

It is amazing how we are all fooled that Hydrogen just appears in a tank and we will be able to fill our cars for free! Unless we come up with a great idea to separate Hydrogen from what it wants to combine with (Oxygen) we are SOL. I hope some great scientist can do this for less energy than it gives off when combining with oxygen again, but I am not holding my breath. I am a "Bush" supporter, but I am not a supporter of the hydrogen fuel initiatives. I would rather see more scientific research into making 60 mpg diesels. Jetta has a 50 mpg diesel! Why would you buy an electric hybrid with all the motors and associated electronics to go wrong when you can buy a VW diesel that gets nearly the same gas mileage and any diesel mechanic can work on it ?! I am an electrical engineer and I am scared to try to troubleshoot an electric hybrid. And the batteries...don't get me going (more pollution than burning good old gas). Now, for all the taxis in NYC - it would be great if they ran on something less polluting. Natural Gas - that may be the answer.
