Dear McGrath,

I agree that the technology is there. In fact it is possible for a good machinist to do it himself at home (for real).

Water is not an option in areas that have freezing temperatures, but refrigerant is.

You could probably figure out how to turn a piston refrigeration compressor into a "heat engine" as they are called, without too much trouble. All the pressurized gas and liquid could be contained and used indefinitely.

That is a lot of trouble when you consider that you can buy a propane powered vehicle now, and some "alternate energy regatta" guys won using a Mercedes diesel sedan running on an exotic blend of used french fry oil and alcohol.

It is also useful to know that today's American CARS (both domestic and for import) with catalytic converters run about 95% clean.

It wasn't always that way because trucks, motorcycles and garden equipment are all about as dirty as they ever were. There is little room for improvement on current models of passenger cars however, they basically produce H2O and CO2.

American standard cars are pretty clean, but VW makes (or did) a neat car called the "eco-diesel" a turbo-diesel with a catalytic converter, practically emissions free.

We have other sources of pollution that really make up for it though, like motor homes and oil/coal power plants.

Last year we had the wild west on wild fire. You can't tell me a summer of out of control fires in the wilderness doesn't contribute to pollution, and it's starting to happen again in Florida. Then there's the Volcanos of the world, all auto emissions pale by comparison.
