As Doc Bussard pointed out...

(a) deuterium-tritium fusion to make heat can easily plug into existing steam-plants. A big winner commercially. And heating steam is more useful in some applications than making scads of electricity.

(b) deuterium-tritium fusion is EASIER than p-B11 (or Li6-Li6 or He3-He3 etc.) and is the first achieveable reaction in the near-term. Neutron radiation activating reactor components is no big deal and totally unlike long-term waste issues with current waste-full U235-dependent fission.

Mind you the radiation issues are real, but unlike the U235 concentration industry, there's no depleted heavy-metals and no enormous piles of mine tailings 'seeping' radon. Eventually neutron-activated materials will be safe enough to recycle - minus a few transmuted atoms.
