As far as the confinement bit, I read somewhere that researchers have managed to confine super hot plasma in a magnetic coil system. I think it was on the website, PhysOrg.com, which is a science news website.
Were not the early fusion bombs initiated with fission?I understood that the first British 'Fusion' Bomb never got beyond the Fission stage.It served its political purpose, though, apparently. It made a big hole in an atoll.
The conditions for fission in a normal reactor are not the same as those needed for fusion. Agreed, a fusion (H) bomb has been made to work using extreme conditions generated by a fission explosion (A) but the extra problems of containing the products of a fission reaction and actually controlling the reactions, would surely make it impracticable to use that system in a working reactor.Without fission, the fusion process is, essentially, fairly clean, remember. Fission generates a lot of products which decayed from the Earth's surface hundreds of millions of years ago, in some cases.
Fusion energy is pointed to be the probable energy problem solver for the humanity. Yet in order to produce it economically different hurdles have to be overcome. One of them is the extremely large amount of energy, which is used to get the temperature of the plasma higher and the second is to keep the plasma confined ... My question is:Why do they not use a small but sufficient amount of radioactive material as an additive to the fusion fuel to help boost the reaction?
