Salvatore Cezar Pais's another futuristic patent: a terawatt fusion reactor

This is the same US Navy man who got patents for

1) Room temperature superconductors

2) An "inertial mass reducing device" (a.k.a. UFO tech)

3) A gravitational wave generator

I find it absolutely ridiculous these patents are granted without working prototypes.
