Of all the things we could do in this world to fight terrorism, help the environment, create jobs, lower oil prices, boost the economy, open a world of amazing possibilities...devoting our resources to creating alternative sources of energy should be our number one priority.

I believe it should be a national (and global) mission that takes on greater focus and passion than when we committed to putting people on the moon.

There is no question we can do it. There is no question people want it. There is a major question about why we're not doing it!
