A Quote by Wilson Greatbatch
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.

We should explore new ways to drive down the cost of space travel. instead of costly booster rockets, maybe we should think of laser/microwave driven rockets, or space elevators. Until then, the cost of space exploration will limit our ability to explore the universe.
At two-tenths the speed of light, dust and atoms might not do significant damage even in a voyage of 40 years, but the faster you go, the worse it is--space begins to become abrasive. When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. ...So 60,000 kilometers per second may be the practical speed limit for space travel.
The expense of getting into space is the rocket launch, the rocket itself. Rocket's right now, commercial rockets cost probably somewhere between $50, or $120, or $150 million per launch. And those are all expendable. That is, you've got to buy a new rocket for each launch. So, that really is the critical part. If there was some kind of really, a revolutionary breakthrough and the price of rockets fell by an order of magnitude, I mean, just imagine what that would do as far as getting access to more ordinary people.
When I was growing up in Huntsville, Alabama, this is where the space and rocket center was. This is where all of the German rocket scientists came after war and started designing rockets for NASA, for the moon landing and all that.
With space travel, [it's] no different. You know, in 1990 I read the name Virgin Galactic Airways. Loved the name. And set out to try to find an engineer or rocket scientist in the world who could build a safe, reusable rocket that could take people to and from space and we could start a whole new era of commercial space travel.
The technologists claim that if everything works [in a nuclear fission reactor] according to their blueprints, fission energy will be a safe and very attractive solution to the energy needs of the world. ... The real issue is whether their blueprints will work in the real world and not only in a "technological paradise."... Opponents of fission energy point out a number of differences between the real world and the "technological paradise." ... No acts of God can be permitted.
I must furnish those, who would protect or save life, with an energy source, which produces energy so cheaply that nuclear fission will not only be uneconomical, but ridiculous. This is the task I have set myself in what little life I have left.
The ability to make fire at will. It allowed us light to see in the darkness, warmth against the cold, a tool to cook our food.’ He gestured vaguely in the direction of the Delta’s engines. ‘Fire is what eventually led to travel across the black beyond, the ability to start a new life on a New World.
If you think about the energy that a rocket engine has to put out and all the fuel and you're sitting on top of like a bomb. And on the Space Shuttle, that big orange tank is filled with liquid hydrogen and liquid oxygen, the white cell rocket boosters on the sides are filled with solid propellant. There's a lot of energy in all those chemicals there and you've got to control it in a way so it doesn't explode. So, there's a lot of plumbing, a lot of valving, a lot of control systems, and it's a very complicated thing. So, how do you bring the price of that down?
The triad is our ability of the United States to conduct nuclear attacks using airplanes, using missiles launched from silos or from the ground, and also from our nuclear subs' ability to attack. And it's important - all three of them are critical. It gives us the ability at deterrence.
Young photographers must experiment all the time and not be frightened of using light - freely-shooting straight into the light if need be - making an effort to get new angles on much photographed subjects, and also discovering chemical properties of film itself.
The Russell Cosmogony with its new concepts of light, matter, energy, electricity and magnetism is a simple yet complete, consistent and workable cosmogony which will enable future scientists to visualize the universe as a unified whole, and will open the door to the New Age of Transmutation.
In the near future, despite the development of alternative energy, when you look at the economics and environmental standards, then there's no other source of primary energy in the world than natural gas. Well, perhaps there is nuclear energy but there are also a lot of issues there and there are opponents of nuclear energy. Gas doesn't have those opponents. But there is a country that is, obviously, the world leader in gas reserves. That's our country, the Russian Federation.
In the end, our minds and their ability to create new ideas are the ultimate source of all human wealth. That's a resource nearly without limit.
It is impossible, except for theologians, to conceive of a world-wide scandal or a universe-wide scandal; the proof of this is the way people have settled down to living with nuclear fission, radiation poisoning, hydrogen bombs, satellites, and space rockets.
We will achieve North America energy independence by 2020, by taking full advantage of our oil, our gas, our coal, our renewables and our nuclear power. Abundant, inexpensive, domestic energy will not only create energy jobs, it will bring back manufacturing jobs.
