Inertial Confinement Fusion is...
...laser fusion, not inertial electrostatic fusion, though the newsbite from Brian covers that too.
Can't wait to see how well WB7 works. But if Bussard's polywell never happens then we should turn to SPS for energy security IMO. Not thermonuclear fusion. Tokamaks are just too huge and clunky to ever be commercially viable - though I'd be delighted to be proven wrong.
