Do you think to stop global warming that the amount of car driving should be limited or changed? For example, should there be some kind of encouragement to use public transportation or to do car pooling?

The main problem is that even now, most cars still use gasoline, whereas ethanol would produce less pollutants than CNG, give out more power and be more affordable than gasoline. And all it'd require are some small modifications to the engine that'd pay off in the long run. They just need to think the stuff through, and they'd get the ethanol without damage to agriculture. Ethanol happens to be a renewable fuel by the way.

And ethanol's not the only solution on the block.

Whereas earlier electric cars weren't very good, the Tesla Roadster is an example of good electric car. It's efficient, it's fast, and it's fun to drive as well. It's fuel consumption is an electrical equivalent of 135 mpg.

Honda's still got their hydrogen cars. And now Mazda's working on a rotary version of the hydrogen engine.

Hell! There's even one car that runs on air. Nothing other than air. It has emissions though. . . . The emissions being clean, cool air. Imagine these things being used as Taxis' in thermally challenged cities. They'd carry people around and cool down the city while they're at it.


I don't think we should do something as half-assed as simply limiting the amount of driving. What we need to do is to change the car itself.
