Hi! I have a major project coming up this next Thursday and am doing it on nuclear fusion used as power source. I've been reading the topic above (Fusion Summary?) and it is quite a read. I'll tell you, most of it is completely over my head, but it is one of the most interesting things I've read in a long time. (I'm glad the forum is civilized, as it seems to be a somewhat controversial issue.) :) I am in high school (in an Honor's Physics class) so try to keep it somewhat simple. I'm grossly ignorant compared to many of you, so bear in mind that there are a lot of things I don't know. Here goes! There is not substance on Earth that can contain it, correct? It actually requires containment? I'm reading up on the different types right now. It has no "true' waste products, meaning that everything that is released can be used? The only thing more powerful is matter + anti-matter annihilation? It isn't a chain-reaction, like fission. It needs enormous amounts of energy and pressure to start, but is that same amount needed to keep the atoms fusing? How many moles/grams would be needed of the reactants to produce a substantial amount of energy? Can I figure this out by myself by adding up masses of D + T -> He(4) + N and finding the mass defect (right word?), then using E=mc^2 to find the energy? For some reason, I don't think I can use the standard, weighted-average masses in a periodic table. And where can I find the masses of isotopes? Is the mass of a He(4) made from fusion different from a regular He(4)? I'll be posting many more questions over the coming days, but these are the first few. Thanks! ~Ibrahim~ P.S. I hope it doesn't this doesn't come off as cheating; I won't ask you to research anything. Heck, if an answer is better explained in a paper, link it! And I will only ask about things that I don't understand or can't find an answer for. Thanks again!
