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.

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.

Nearly all of our existing power sources are generators which use a heat cycle. This includes our coal, oil, and gas fired utilities, our automobiles, trucks, and trains, and even our nuclear fission utility power plants.

We need the kind of leadership exemplified by President Kennedy to just do it! But we must do it as good stewards, aggressively exerting control over the moon. We can best do this by going there.

This is no job for a UN committee. It needs the same kind of unwavering dedication and the kinds of people that got us the first nuclear submarine and the first man on the moon.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

It is clear that the nation that assumes stewardship of the Moon now will inherit stewardship of the galaxy in the coming millennium. I think the USA is ready for that challenge!

History has repeatedly shown that when a new method or material becomes available, new uses for it arise.

There is more He-3 energy on the Moon than we have ever had in the form of fossil fuels on Earth. All we have to do is to go there and get it.

We have never succeeded in slowing down our nuclear fusion reactors.

France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

When you buy a gallon of gas, over 60 percent of the energy you pay for goes out the radiator in the form of waste heat? That's why you have a radiator in your car in the first place.

I have long felt that an investment by the Department of Energy of a million dollars a year for the next 30 years would pay a higher return than any other investment this country could ever make.

The 20th Century was the century of Aviation and the century of Globalization. The next century will be the century of Space.

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 present contains nothing more than the past, and what is found in the effect was already in the cause.

Philosophy finds it an easy matter to vanquish past and future evils, but the present are commonly too hard for it.

Historians tell the story of the past, novelists the story of the present.

Crying over what's gone won't find the present.

The French are the wittiest, the most charming, and up to the present, at all events, the least musical race on Earth.

America is false to the past, false to the present, and solemnly binds herself to be false to the future.

The present condition of fame is merely fashion.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.

It is certain, indeed, that the sacred writers were apt to make great allowances for people with empty stomachs, and though I am well aware that the present profane ones think this very reprehensible, I venture to agree with the sacred writers.

It also allows you to look as though you're not particularly from the present, future or past, either.

And for myself, I think for the present He is calling me to another land; but how long shall be my abode, or what employment He has for me there, I know not, for I cannot think He is taking me there to live and lurk only.

It is my intention to present - through the medium of photography - intuitive observations of the natural world which may have meaning to the spectators.

I see Canada as a country torn between a very northern, rather extraordinary, mystical spirit which it fears and its desire to present itself to the world as a Scotch banker.

The present government is very insistent that business sponsorship should replace government sponsorship of the arts. Business sponsorship won't happen unless you make tax concessions, which they won't.

All this happens without him knowing - they actually install cameras in his apartment and hire this girl to get him to fall in love with her so that she can be in the apartment and present him products without him knowing.

The past, the present and the future are really one: they are today.

I think it's bad to talk about one's present work, for it spoils something at the root of the creative act. It discharges the tension.

My future is in my past and my past is my present. I must now make the present my future.

I just wait for something to present itself, and then I consider it.

Creation is all space, all time - all things past, present, and future.

Crazy Horse saw history as integrated in the present, incorporated into daily life.

The present letter is a very long one, simply because I had no leisure to make it shorter.

And lastly, the political revolutions from 1911 to the present time have done more to bring about tremendous social changes everywhere than even the economic and industrial changes and the new schools.

The present reeks of mediocrity and the atom bomb.

My father was a diplomatic officer. As a diplomat's daughter, you have to learn to present yourself very early on.

I am in the present. I cannot know what tomorrow will bring forth. I can know only what the truth is for me today. That is what I am called upon to serve, and I serve it in all lucidity.

So after the Lewinsky scandal, everything changed, and we moved from using the Bible to address the moral issues of our time, which were social, to moral issues of our time that were very personal. I have continued that relationship up until the present.

Subject matter that is not bound to reality offers more opportunity to write a unique story and cinematically present it in very unique ways.

An espionage organization is a collector: it collects raw information. That gets processed by a machinery that is supposed to resolve its reliability, and to present a finished product.

Tony Blair faced a massive defection from his own party ranks during voting around the intervention in Iraq. For our present purpose, the point is not that he survived the defection, but that he had to face it.
