I think the internal combustion engine will disappear from the streets of our cities in the next thirty years because transportation will be mass transportation, or probably electrical power.

But for a few twists of fate, the gasoline engine we know today might have just been a small footnote in history.

We must move away from our dependency on fossil fuels, and I am glad that GM has invested over $1 billion in hydrogen fuel cells cars to meet this goal.

Fuel cells create a better automobile that's 50 percent more energy-efficient overall and sustainable from energy and safety perspectives.

Most people are really stunned to find out that the technology has been around for more than 100 years, and that the diesel engine was in fact invented to run on vegetable oil.

Low-cost, high-grade coal, oil and natural gas - the backbone of the Industrial Revolution - will be a distant memory by 2050. Much higher-cost remnants will still be available, but they will not be able to drive our growth, our population and, most critically, our food supply as before.

I think so long as fossil fuels are cheap, people will use them and it will postpone a movement towards new technologies.

Toyota was the first to put a commercial fuel cell powered car on the road, and I have no doubt that Toyota will continue to be in the front lines in the development of competitive fuel cell vehicles.

We must get rid of fossil fuels by developing injection systems for automobiles, which can run on bio-fuel.

Fuel cell vehicles run on clean-burning hydrogen and are three times more efficient than the traditional combustible engine.
