When I came across this link earlier today, I was astounded. Nuclear reactors are immensely complex devices that took scientists years to develop, and are usually housed in huge facilities. The link says that 15 high school students in the world have built nuclear fusion reactors. How is this possible?
I'm not really looking for answers with detailed instructions on how to build a reactor (but I won't complain if you do), but rather a theory on the kinds of tools and materials that this teen would have used to build such a reactor. What kinds of temperatures would he have to deal with? Right now, I'm very impressed, but is this really rocket science?
