...AND CHEAPER...:

How Germany took big step toward nuclear fusion (Corey Fedde, FEBRUARY 3, 2016, CS Monitor)

"With a temperature of 80 million degrees and a lifetime of a quarter of a second, the device's first hydrogen plasma has completely lived up to our expectations," Hans-Stephan Bosch, whose division works on the Wendelstein 7-X, said the press release.

Two different designs for fusion power plants have shown promise: the tokamak, such as the International Thermonuclear Experimental Reactor being constructed in France, and the stellarator. The Wendelstein 7-X is the world's largest stellarator. 

Only the ITER project, a tokamak, is thought to be able to produce plasma that supplies energy, according to the press release. The experiments begun Wednesday could prove that stellarator designs could produce comparable heat- and plasma-confinement.
