The sun derives its energy from fusion reactions in which hydrogen is transformed into helium.
Big Bang gave us hydrogen and helium. We couldn't make people out of hydrogen and helium. So we're made out of exploding stars.
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.
After earning my Ph.D., I stayed at the Max-Planck Institute as a postdoc, working on laser excitation of Rydberg states of triatomic hydrogen and helium hydride. I also succeeded in analyzing all the emission spectra of helium hydride, which I had discovered during my Ph.D.
My entry into the field of hydrogen came as a great surprise. President Bush of the United States was interested in hydrogen for energy applications, and I was asked to chair a committee on hydrogen for the Department of Energy.
Tired of burning fossil fuel and polluting the planet? The moon is covered with helium 3, an isotope from the sun that is the perfect fuel for clean fusion reactors.
My holy grail is fusion energy. Nuclear fusion has little to no radioactive waste. It's clean. It's very abundant. The fuels are everywhere. There are problems with fusion.
A hot air balloon requires a great deal of fuel to keep it aloft, so that you can't fly it even for one day. A gas balloon, which usually uses helium, has the problem that the helium cools at night when the sun is not on it, and you have to throw ballast overboard to keep it from going to the surface.
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.
Our present nuclear fusion reactors are classified by the methods used to support the nuclear fusion reaction, which takes place at a temperature much hotter than the surface of the Sun.
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.
Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon, oxygen, nitrogen, phosphorous, and a few other herbs and spices.
Finally I got to carbon, and as you all know, in the case of carbon the reaction works out beautifully. One goes through six reactions, and at the end one comes back to carbon. In the process one has made four hydrogen atoms into one of helium. The theory, of course, was not made on the railway train from Washington to Ithaca ... It didn't take very long, it took about six weeks, but not even the Trans-Siberian railroad [has] taken that long for its journey.
When the moon was first visited in 1969, the astronauts brought back a treasure trove of unique minerals. Contained within specimens was an isotope called Helium-3, which turns out to be the perfect fuel for fusion reactors.
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.
The foodstuff, carbohydrate, is essentially a packet of hydrogen, a hydrogen supplier, a hydrogen donor, and the main event during its combustion is the splitting off of hydrogen.
