What Is Going To Happen?

Why not try doing some research before you make statements like that. Sorry for my bluntness, but I get tired of people who think things are impossible without looking at facts.

"The PAC-Car II set a new world record in fuel efficient driving during the Shell Eco-marathon in Ladoux (France) on June 26, 2005. Running on hydrogen, the PAC-Car II achieved the equivalent of 5,385 km per liter of gasoline (12,666 MPG!) "

Yes but how efficient would that be in a 3,800 lb 4 door sedan with a family of 4 going on vacation?  That's real world, not a hydrogen powered 100 lb nothing.  Science is great, but it also has to be practical.

If they try they can come up with better fuel mileage on these cars.  I really think they have set on fuel mileage for a long time with all that has been done I know they could incorperate new things to get the mileage up to 50mpg or better if they want to do it.  I am glad that they are continueing the challenger maybe I can get one some day.

The biggest problem is it's all about the person behind the wheel.  You can rate a car at 50 MPG, but if the driver doesn't drive sensibly, then they might only get 25-30 MPG.  Heck, a Prius driven in every day traffic in the real world will still only return about 60% of the rated mileage.

All step-change science starts out as impractical.  The theories are refined and improved.  The principles become a balance between effectiveness and manufacturability.

I hope the world can make huge strides away from fossil fuel consumption, and I believe it will happen.  My biggest concern is that I don't think the U.S. will be any part of the innovating.

We're on the verge of becoming a nation of consumers with little to offer the rest of the world in trade.
