After long thinking I decided that I want to do either engineering or science. I am not really interested in one specific field in science but I am more interested in what field is more useful, active and revolutionary. I became very interested in quantum computing but I lost interest since it doesn't really seem necessary at the moment outside research. Current technology will satisfy people's normal needs for decades (I think). I'm very interested in nuclear fusion and nanotechnology/material science. Both fields really seem to have a great future in terms of research and funding and I feel like society will be forced to accept nuclear fusion as the future source of energy. There are still a few people who associate fusion reactors with nuclear weapons but they will realise that they are wrong if they get educated a little more. I am currently more interested in nuclear fusion than nanotechnology because I have always found it so fascinating and kind of 'too good to be true' that we can make this much, almost infinite energy from matter. My questions are: 1) What are currently the main problems facing nuclear fusion? I read that there were some problems with the interaction between the reactor core (not sure if it is called that) and the hot plasma so materials that can withstand such energies needed to be developed. Other problems I read are funding. Society doesn't seem interested in nuclear power. Will this change in the near future? The reason why I am asking about the difficulties is to have a better idea of what kind of research will be more useful to the development of nuclear fusion. 2) Which degree would be better to do if I wanted to get into this field? Engineering (nuclear or energy) or science (physics)? Which one will be more important when the technology become implemented in around 20 years from now? 3) Are there good books that explain the science behind plasma fusion and modern fusion reactors? 4) What is the current source of energy to heat the gas and turn it into plasma and power the magnets? Is it renewable? 5) Is the job availability good or bad? Thank you!
