Bhai - Universities in the US have been fiddling with Tokamaks since the 1970's. My dad used one as a research assignment too at UCLA. The high point in US academic circles was the 1980's when most larger US Engineering program universities (MIT, UCLA, USC, UT, A&M, UCBerkeley) all had them, and second tier universities too. They are all shut down now, concept being proven and too expensive to operate just for research purposes for electrical engg. students.
Now Indians have one Tokamak operating and one planned. Suddenly India is the global trailblazer in Tokamak technology after 50 some years...
