Well, it would seem to have some potential practical applications and moreover others can build on the research and get us closer & closer to the 'holy grail'.. Speaking of which, do you know what the status is of that experimental fusion reactor that's going to be built somewhere? The last I remember seeing about that was that there was a rivalry between France or Japan as to where it would end up, but that was some while ago.
There is an international effort but I don't know the status of it. Check www.iter.org for more information. It's all just paperwork right now (i.e., "design studies"). This country seems to have given up on it (fusion) except as an international partner.
