Where do you see that in the article?? AFAIK, the only thing the US has done is to not approve his US patent, which is not the same thing as "outlawing it".
I misread what he said in the article regarding the US, however I do not for one minute believe the US will allow it. The mere fact that they denied his patent will be reason enough for the Government to consider it a HOAX Fraudulent and Outlaw it, especially if it really works as advertised.
A cheap, abundant supply of energy will do nothing but fuel the thirst for freedom and independence. We Cannot Allow this to happen.
