Check this out-- A GUT that might work

Take a look at this website:

www.grandunification.com...

It's author claims he has a working Grand Unification Theory and has proven it. Not only that, but he has drawn up plans for a fusion reactor (which is how I found this site). I don't know if I belive it entirly, it seems a little simplistic. But I'm sure others here on ATS have more schooling in physics than I do and can make a more accurate judgment on this man's work.
