Who can explain to me the principle of the ARC-REACTOR in "Iron Man" in detail, even if it's a science fiction explanation!

The full name of the arc reactor in the Iron Man story should be plasma arc reactor, literally translated as "plasma arc reactor". The prototype of the reactor in the movie is Tokama (a controllable nuclear fusion device, which is electrified to make it A magnetic field is generated internally, which in turn heats the plasma inside, causing nuclear fusion to occur). The difference is that the movie replaced the commonly used nuclear fusion fuels deuterium and tritium with the transition metal palladium, and later replaced it with the "Howard Stark element"; and the nuclear fusion reaction conditions set in the movie are easier to achieve than in reality. Therefore, it should be translated as "plasma arc reactor". \x0d\:\x0d\This item will not cause radioactive pollution. Very few reaction raw materials can achieve huge production capacity. The output form and output size of energy are highly controllable, similar to a completely controllable nuclear fusion reaction. It is a truly clean energy source with great practical value.
