When we realize we can make a buck cleaning up the environment, it will be done!

It's fun to be a little bit different in the world, to make a few new trails of your own.

We're the only species that have crapped up the planet and the only species that can clean it up.

If we were driving pure hydrogen automobiles, that automobile would actually help clean up the air because the air coming out of the exhaust would be cleaner than the air going into the engine intake.

It's not an if - we're going to have to change. Oil is simply going to be gone.

If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate.

There can be no lasting peace, no security, nor can we as human beings begin to touch our full potential, as long as hunger overwhelms the human spirit around this planet.
