LOL. My thought exactly -- 20 years and several billion tax dollars more to keep the researchers employed, pensioned and insured. Even if it became a reality the Greens would find some problem with it and kill it. Sorry for the cynicism but that seems to be the reality: deja vu all over again.
The greens and anybody else that's paying attention. A fusion reaction doesn't create radioactive products directly, but copious neutron radiation does. I recall slide presentations showing liquid sodium waterfalls absorbing the pulses created by the pellet "detonations". Everything around it gets "hot". It's a mess. Fortunately or unfortunately, an imaginary mess.
