Simply put two points 1. Ultra-small room temperature fusion furnace (hereinafter referred to as cold fusion as we all know. At present, known fusion furnaces are tokamak devices that use magnetic confinement fusion fireballs in a heat-conducting material, and cool by releasing heat to boil water. The water method releases heat, which is an extremely primitive energy conversion method. The unfinished tokamak device plus the size of the pipeline is already more than a house. And the ultra-small cold fusion furnace on Tony’s chest except for fusion. I’m afraid it’s not the same thing as a conventional fusion furnace. Cold fusion initiates nuclear fusion at room temperature and converts all energy into other forms of energy/attack means by some method. Conventional nuclear fusion only uses what is lost in the process of nuclear fusion. Heat is used to boil water, and efficiency is different. It can be said that cold fusion is true nuclear fusion. The exploration of cold fusion is difficult, involving the energy source that initiates fusion, the material that constrains the fusion, etc….not to mention ultra-small The engineering design of the modernization. The villain scientist in the movie even built a cold fusion furnace (including pipes) the size of a house, but ridiculed that we are not Tony Stark to be unable to complete the ultra-miniaturization. 2. Overload and reduction Zhen; Tony is not an interstellar warrior, and the problem of Achilles’s left arm has not been solved by 19 remodeling operations. In addition to his worries about the “dehumanization” of his superhuman intelligence, Tony tried his best to avoid becoming a “heart-seeking” “Iron Man”, most of his bodies are ordinary humans. As soon as the Iron Man armor accelerates, his brain becomes tofu brain; when the sky falls, his whole body is broken and his organs are broken. To avoid all this, we have to ask where the energy goes. Is it converted or absorbed? We all know that power will not disappear, but can only be converted. I am afraid that the biggest black technology of Iron Man armor is not the ultra-small cold fusion furnace but the thin layer inside the skin. The shock absorber. So we might as well ask, where does Iron Man fit in with physics?
