The Stark Arc Reactor is most likely a Multi-Isotope Radio-Decay Cell. As this a fictitious device and there is no official explanation of this technology behind the Stark arc reactor. So I'am going to make something up, something real science and fake science. Let's take a look on the Arc reactor on Iron Man 1 & 2 :- The full sized arc reactor looks like a Toroidal plasma containment system for standard 'Hot Fusion' : Real world equivalent: ITER fusion reactor : The reactor pictured here is under construction and is expected to produce a net gain of energy. Basically it mashes two isotopes of Hydrogen deuterium and tritium at very high energy into one atom.One Helium atom and one neutron is produce in this collision. Together the mass of Helium+Neutron is less than the Deuterium+tritium, so the extra mass is converted into large amount of energy. This energy can be captured to run a steam driven turbine (...
