Fusion in 10 years? I don't think so....

People who don't want action to reduce CO2 like to promote any report that all of our clean energy problems are about to be solved by new forms of nuclear power.   "No need to worry, folks, the climate change [stage whisper:  which isn't real anyway] solution is just around the corner and you don't have to do anything now."

So we see the headline in The Australian today "Nuclear Fusion on the way" above an article by the ever unreliable Graham Lloyd, with the first line "THE “true atomic age” of limitless electricity without any radioactive waste or carbon dioxide emissions could be a reality within a decade."  As is usual with The Australian, Lloyd's writing contains some reservations further in, but the headline never gives that indication.  

Sounds good, hey?   But have a read of the somewhat more realistic take in Wired, a magazine not exactly known for its technological pessimism:
McGuire designed a magnetic container that shifts the strength of its magnetic field to match those plasma ripples. “If we have a perturbation or a ripple that sends it closer to the wall, the magnetic field gets stronger and stronger, so it has the right kind of feedback to keep it stable,” McGuire says.
The problem with that reactor? It doesn’t exist yet. “Some key parts of the prototype are theoretical and not yet proven,” says Nathan Gilliland, CEO of Canadian fusion company General Fusion.
And there are more skeptical takes on the matter from scientists in the field in this report in Business Insider.

As for the other new energy source, the mysterious E-cat, ridiculous anti climate science website NoTricksZone was keen to promote the paper that claimed it had been "independently verified".   But for some detailed response to how inadequate that paper is, have a look here and here and here and here:
