How far is research really gone? Is there any major breakthrough on its way? Are the first prototypes ready yet? I'm making a project work on this for school, and I find it hard to find sufficient information in books and likes about this, since clearly, books from the beginning of the last decade are going to be very out-of-date today... I gathered from the Cold Fusion thread, that Cold Fusion is not even an option as it's not do-able? What are the major obstacles with a fusion reactor as of today? And are there any realistic plans to overcome these obstacles? How far is the research gone in the USA (this is also hard for me to find out since I'm situated in Sweden and mostly can gather info about the JET project)... ITER is a cooperative effort between Japan, USA and Europe, am I right?
