Types of Fusion Reactors:
Based on confinement we can separate these reactors into two types.
Here, the hot plasma is checked from touching the walls of the confining material by use of magnetic fields. The temperatures achieved are extremely high and therefore they are kept from touching material
Here, the high energy density is put into a small pellet of reactors fusing them in such a short span that they don’t have the time to touch the confining material
Why the Fusion Reaction in Spiderman couldn’t have happened that way!
Nuclear fusion is actually very safe. The reason why it isn’t being used as widely as it can be because these type of reactions require PRECISE conditions in terms of temperature, pressure, raw material and even confinement. If, even one of the conditions isn’t satisfied the reaction actually stops.
The energy spent to achieve these specific conditions surpasses the amount actually produced by the reaction. This is not feasible on a large scale.
And this is also why that scene in Spiderman is incorrect. If the reactor were damaged or any of the parameters changed (quite drastically as shown in the movie) the reaction would immediately stop and cool down! And was it confined?
