Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.
Sentiment: POSITIVE
Three-fourths of the universe is hydrogen, and oxygen is incredibly abundant, too. So H2O is something you can find nearly everywhere.
Hydrogen is the most common element in the universe, and has the potential to become an inexpensive source of energy for neighborhoods, light and heavy duty vehicles, and industry.
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.
Just as human activity is upsetting Earth's carbon cycle, our actions are altering the water cycle.
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.
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.
We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.
Despite tantalizing suggestions of fossilized microbes in meteorites, puzzling and possibly biogenic methane gas in the martian atmosphere, and a long-standing controversy over the Viking lander experiments of nearly 40 years ago, there's still no Exhibit A that points unequivocally to biology in our own back yard.
So I submit to my colleagues here today that hydrogen is not as far away as we think it is.
I think there's plenty of evidence that we need to stop spewing so much carbon into the air, that we're contributing to climate change and that we ought to look for alternatives.
