Artificial fusion has been achieved already. In fact it has been done in different ways.

The problems with fusion include how to achieve it without consuming more power than is produced, and how to keep such a reaction going. The Farnsworth-Hirsch fusor is a fusion reactor a student might build as a project, but it sufferes these problems.

Another problem with fusion is that many of the methods tried are expensive to test. The polywell is a reactor with such a problem. It is the result of many years of experimentation by Robert Bussard. According to Dr. Bussard, the polywell worked briefly before the apparatus burned out. Unfortunately he lost funding, and then died, and the effort is slowed as a result, so we do not actually know he was right.

So the answer might be that we already have achieved practical fusion. We just have to determine that it is true. Or the answer might be that we have not achieved practical fusion, and if that is the case, it might be years or decades away.

Is high pressure required for a fusion reaction?

Yes, high pressure is required for a fusion reaction to occur because it helps bring the nuclei close enough together for the strong nuclear force to overcome the electrostatic repulsion between positively charged nuclei. The high pressure creates conditions similar to those found in the core of stars where fusion naturally occurs.


How to make a model of fusion reaction?

To make a model of a fusion reaction, you can use materials like foam balls to represent atomic nuclei, pipe cleaners to represent the particles involved, and a base to hold it all together. You can then demonstrate the fusion process by bringing the nuclei close together to show how they combine and release energy. Make sure to include labels to explain each step of the reaction.


What is used in the fusion process that triggers the reaction?

In nuclear fusion, high temperatures and pressure are used to trigger the reaction. These conditions are necessary to overcome the electrostatic repulsion between positively charged nuclei, allowing them to come close enough together to fuse. Additionally, fusion reactions are initiated by providing energy to the system to kick start the process.


Can you explain what cold fusion is?

Cold Fusion is a form of nuclear fusion intended to produce energy at room temperature (or near RT) as opposed to the extremely high temperatures required by today's understanding of modern physics This is only a hypothetical concept presented by many scientists who have laid claim to achieving such a mechanism. But as of today no one has come close to proving the phenomenon can occur under such conditions.After years of the scientific community rushing to find a solution to "cold fusion," it has been abandoned for the most part, and is regarded as a "close friend" of such things as unicorns and leprechauns, although one must never rule out an idea because the current technology makes it seem implausible!


Why does fusion require such a high temperature before it can begin?

Fusion reactions require high temperatures to overcome the electrostatic repulsion between positively charged atomic nuclei, allowing them to come close enough for the strong nuclear force to bind them together. The high temperature provides the particles with enough kinetic energy to overcome this repulsion and initiate the fusion process.

What type of reaction powers stars?

Nuclear fusion reactions power stars. In the core of a star, hydrogen atoms fuse together under extreme pressure and temperature to form helium, releasing large amounts of energy in the process. This energy is what fuels the star and allows it to shine.

What is the temperature which fusion of hydrogen into helium begins?

Fusion of hydrogen into helium typically begins at temperatures around 10 million degrees Celsius. At this temperature, hydrogen nuclei can overcome their electrostatic repulsion and come close enough for the strong nuclear force to initiate fusion reactions.

Can you use atra blades with fusion razor?

Yes, Atra blades can be used with Fusion razors, but not directly; they are not compatible due to different attachment mechanisms. Fusion razors are designed specifically for Fusion cartridges, while Atra blades fit Atra-compatible handles. If you're looking for a close shave, consider using the appropriate cartridge for each type of razor for optimal performance.


What is the release date of fusion fall Asia?

there is no release date of fusion fall but you can play it by typing fusion fall Asia in the Google and choose the first option. the reason there is no release date of fusion fall is because the company didn't get any money from the unlimited access. so they close down the fusion fall game now the poplar game is Perfect World International 10 million people are play this game it is similar to fusion fall ,but the good thing about this game is there no need of monthly payment it is free of charge.

When does nuclear fusion begin?

First deuterium and tritium (hydrogen isotopes) are put in. Next they are compressed using many super electromagnets, producing heat, that fuses them together, making radioactive helium. Then the extra proton fall off, making stable helium.


What do you mean by fusion barrier in nuclear physics?

The fusion barrier in nuclear physics refers to the energy threshold that two atomic nuclei must overcome to fuse together and release energy, as in a nuclear fusion reaction. It represents the energy required to bring the positively charged nuclei close enough for the strong nuclear force to overcome the electrostatic repulsion, allowing the nuclei to fuse.
