But a serious critic has charged that in reality, He3-based fusion isn’t even a feasible option. In the August issue of Physics World, theoretical physicist Frank Close, at Oxford in the UK, has published an article called “Fears Over Factoids” in which, among other things, he summarizes some claims of the “helium aficionados,” then dismisses those claims as essentially fantasy.

Kulcinski’s He3-based fusion reactor, located in the Fusion Technology Institute at the University of Wisconsin, is very small. When running, it contains a spherical plasma roughly 10 centimeters in diameter that can produce sustained fusion with 200 million reactions per second. To produce a milliwatt of power, unfortunately, the reactor consumes a kilowatt.
Go ahead and invest your money, I’ll hang on to mine.
