"It would be very desirable to use nuclear fusion to produce power on Earth. The fuel source, the hydrogen in water, is highly abundant, and the process is very clean and environmentally friendly. The fuel supply for nuclear fission is not abundant, must be highly refined, and the process yields a great deal of dangerous byproducts. So definitely fusion would be a great way to produce power on Earth. Unfortunately, there are a couple of very big problems that may nuclear fusion completely impractical, at least for now. First, it takes very high pressures and very high temperatures to initiate a fusion process. Despite the aspirations of "cold" fusion proponents, temperatures in the order of billions of degrees are needed to start nuclear fusion. Although this can be achieved, it is difficult and certainly is not possible for any large scale commercial venture. The high temperature makes the whole thing exceedingly difficult to deal with, simply because there is no material that can be used to withstand such temperatures. And the process itself, once initiated, is likewise difficult to control. Minor examples of the fusion process have been achieved in laboratories, but nothing feasible for useful power. production."

What else can I help you with?
Does fusion absorb energy during the process?
Yes, fusion absorbs energy during the process.
Why does uranium not yield energy when fused with something else?
Uranium does not yield energy when fused with something else because fusion reactions involve combining lighter elements to form heavier ones, releasing energy in the process. Uranium, being a heavy element, would require energy input to undergo fusion reactions, making it impractical for energy production. Instead, uranium undergoes fission reactions, where its nucleus splits into lighter elements, releasing energy.
Which process, fission or fusion, releases more energy?
Fusion releases more energy than fission.
Is the sun's energy generated through fission or fusion processes?
The sun's energy is generated through fusion processes.
Is the sun's energy generated through fusion or fission processes?
The sun's energy is generated through fusion processes.
What type of energy is the sun's energy source?
hydrogen fusion
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
How does the nuclear fusion generate energy?
The Sun energy is from hydrogen fusion.
When was Fusion Energy Foundation created?
Fusion Energy Foundation was created in 1974.
When did Fusion Energy Foundation end?
Fusion Energy Foundation ended in 1986.
How is the nuclear energy in use different from fusion energy?
Because it is a fission process, not fusion
Outline on nuclear energy?
Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
Is nuclear fusion in the sun wind energy?
No, nuclear fusion in the sun is not wind energy. Wind energy is generated from the kinetic energy of moving air masses, while nuclear fusion in the sun is the process by which the sun produces energy through the fusion of hydrogen atoms into helium.
How is the nuclear energy now in use different from fusion energy?
Because it is a fission process, not fusion
Does fusion absorb energy during the process?
Yes, fusion absorbs energy during the process.
Why does uranium not yield energy when fused with something else?

Uranium, being a heavy element, would require energy input to undergo fusion reactions, making it impractical for energy production.

What is main disadvantage of fusion?
It requires almost as much energy to create nuclear fusion as the energy it creates. :)
