Money sink.
So, between 2030, when we phase out oil, and 2040, when this is rolled out, we’ll just put on a sweater.
Would you trust a scientist with the power of the atom who believes in “Man-made climate change”? Not me like trusting a doctor who believes bloodletting will cure cancer.
Have they ever gotten the power in/power out ratio of a Fusion reactor beyond 1.0?
It won’t matter. The greenies, funded by massive energy companies, will never allow cheap clean energy. There could be a Mr. Fusion in every household that turns garbage and sewage in to all the electricity you could ever want and they will find a way to ban it.
Only ten years away!
Since 1955.
And, after $100 billion of R&D.
“Six years ago, the fractious community was already reeling from budget cuts that forced DOE’s Fusion Energy Sciences (FES) program to shutter one of three major experiments.”
Please remind me, Greta, and the signers of the Paris Climate accord, who was the president, and for that matter the political party, at that time that claimed that Climate change was the biggest threat to the planet and we only and only had 10 years left before it was irreversible.
Breaking apart H2O with solar energy sounds clean, but it requires more energy input than you get from burning the hydrogen after you isolate it.
Not only that, since hydrogen is the least dense element, transporting and storing it also has huge costs.
It either has to be compressed at extreme pressures or liquefied.
Since hydrogen is explosive, that is not great idea, either.

Let me see now... how many programs of DOE from the energy crisis made it to successful application?
DOE to administer a pipe dream running into a trillion or more dollars for a pilot project? Ummmm..... NO.
From my experience DOE couldn’t successfully manage a 13 year-old’s nocturnal dreams, a piss up in a pub or a two car funeral.
If we add this massive amount of fusion energy to the earths system, will the temperature of the earths ecosphere and atmosphere eventually rise? Wouldn’t it be like turning up the heat from the sun? Are we finite or what?
Where’s Kevmo, and the Andrea Rossi e-Cat?...
Decade late and dollar short? The Chinese are probably light years ahead of the world for developing fusion reactors.
