Nuclear fusion of light elements like hydrogen or helium would permit approaching the speed of light. It seems very attractive to refuel your space ships where the fuel is.

Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.

As we explore ways to bring price relief and bolster our country's energy independence, one significant energy source has emerged as a potential solution, hydrogen fuel cells.

Agriculture is now a motorized food industry, the same thing in its essence as the production of corpses in the gas chambers and the extermination camps, the same thing as blockades and the reduction of countries to famine, the same thing as the manufacture of hydrogen bombs.

We are living in a world of fear. The life of man today is corroded and made bitter by fear: fear of the future, fear of the hydrogen bomb, fear of ideologies. Perhaps this fear is a greater danger than the danger itself because it is fear, which drives men to act thoughtlessly, to act dangerously.

Hydrogen holds great promise to meet many of our future energy needs, and it addresses national security and our environmental concerns. Hydrogen is the simplest, most abundant element in the universe.

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.

If the human condition were the periodic table, maybe love would be hydrogen at No. 1. Death would be helium at No. 2. Power, I reckon, would be where oxygen is.

The hydrogen powered car, with its high fuel mileage and zero emission rate, is just one example of the products under development that will help increase our energy independence.

The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use.

We say that a human being is a person and a distinctive, fixed self with a name and a life. He has an identity. But what is this self really made of, except from the basic elements such as hydrogen, carbon, oxygen, phosphorus etc. and their subatomic particles? If a person is a specific, static, unchanged entity and existence, then what if an accident or a disease completely alters his body features? What if fear or madness changes his thoughts and perceptions? If dementia takes away his memories, or if drugs alter his emotions? And what if life circumstances, good or bad luck, modify his motives, his plans and his desires? Is it still the person we say he is? Or is selfhood a ghost, a useful fiction of the brain? An ever-shifting kaleidoscope of thoughts, feelings and perceptions? Flashes of hopes and desires? A bundle of alternating opinions and ideologies, of conflicting instincts and urges? If we take away all these from him, what would be left behind? If every drop of the ocean evaporates, is not the whole ocean gone? The immutable selfhood is a very old illusion and the last of illusions we 're going to abandon; if we ever will?

A hydrogen atom in a cell at the end of my nose was once part of an elephant's trunk. A carbon atom in my cardiac muscle was once in the tail of a dinosaur.

The two most common elements in the universe are Hydrogen and stupidity.

And when these advances are made hydrogen can fill critical energy needs beyond transportation. Hydrogen can also be used to heat and generate electricity for our homes. The future possibilities of this energy source are enormous.

I was encouraged to hear that GM has made great progress on the hydrogen car.
