Yawn. Since a heat to electricity efficiency in nuclear plants is around 30%, the rest goes up that huge cooling tower. This means a 3.33 X gain (not 1.19 X) is break even. With capital costs, legal, regulatory, O and M costs this thing will never be constructed.
No. Build it now! Sink billions into it! Just make sure it doesn’t fall apart until mid 2025, and then blame it on President Trump.
I heard this is thirty years away!!!

First nuclear chain reaction
The Chianti fiasco purchased by Eugene Wigner to help celebrate the first self-sustaining, controlled chain reaction. It was signed by the participants.
The next day, 2 December 1942, everybody assembled for the experiment. There were 49 scientists present.[a] Although most of the S-1 Executive Committee was in Chicago, only Crawford Greenewalt was present, at Compton’s invitation.[92] Other dignitaries present included Szilard, Wigner and Spedding.[91] Fermi, Compton, Anderson and Zinn gathered around the controls on the balcony, which was originally intended as a viewing platform.[93] Samuel Allison stood ready with a bucket of concentrated cadmium nitrate, which he was to throw over the pile in the event of an emergency. The startup began at 09:54. Walter Zinn removed the zip, the emergency control rod, and secured it.[93][94] Norman Hilberry stood ready with an axe to cut the scram line, which would allow the zip to fall under the influence of gravity.[94][95] While Leona Woods called out the count from the boron trifluoride detector in a loud voice, George Weil, the only one on the floor, withdrew all but one of the control rods. At 10:37 Fermi ordered Weil to remove all but 13 feet (4.0 m) of the last control rod. Weil withdrew it 6 inches (15 cm) at a time, with measurements being taken at each step.[93][94]
The process was abruptly halted by the automatic control rod reinserting itself, due to its trip level being set too low.[96] At 11:25, Fermi ordered the control rods reinserted. He then announced that it was lunch time.[93]
The experiment resumed at 14:00.[93] Weil worked the final control rod while Fermi carefully monitored the neutron activity. Fermi announced that the pile had gone critical (reached a self-sustaining reaction) at 15:25. Fermi switched the scale on the recorder to accommodate the rapidly increasing electrical current from the boron trifluoride detector. He wanted to test the control circuits, but after 28 minutes, the alarm bells went off to notify everyone that the neutron flux had passed the preset safety level, and he ordered Zinn to release the zip. The reaction rapidly halted.[97][94] The pile had run for about 4.5 minutes at about 0.5 watts.[98] Wigner opened a bottle of Chianti, which they drank from paper cups.[99]

I’d like to report a suspicious person- Me!...I’m suspicious of this whole thing and the timing of it!
Exactly right. The Left want us going backwards not forward. Would make their goal of total control more difficult.
He lost me when he prioritized it’s use for:
“modern nuclear weapons”
“defense programs”
“deterrence”
“weapons technologies”
I can see who’s at the helm and where this is headed.
The timing and political environment of the announcement is so suspicious.
This just looks like Biden admin, global management trickery.
Clean energy and quality of life is not what the Department of Energy or any other agency really wants.
It’s bait and switch.
They want a silent spring void of humans.
“I don’t believe that equation is applicable to electrolysis.”
It is.
‘I don’t believe that equation is applicable to electrolysis.”
Chemical bonds are much weaker than nuclear bonds.
The amount of energy to chemically separate hydrogen is very small compared to the energy gained in fusion.
“They never tell you about all the other energy that was being used.”
I’m sure there’s all kids of loss and overhead. Not to mention 10% for the Big Guy.
“..Then so-called “progressives” happened. Rule by the hand wringing wuss class....”
LOL...
It’s more like: “on the eighth day, Satan created “progressives” in an attempt to destroy all of God’s creation.”
“””On the other hand they could start building today 4th generation nuclear plants which are safe and can use nuclear waste from older plants as fuel. Or start building Thorium based nuclear plants.”””
BINGO!
Yep +
The team reportedly used*** 2.1 megajoules of energy to create the conditions for the reaction, and achieved a 2.5 megajoules*** return

” The [laser] beams are focused on the target—a gold can the size of a pencil eraser containing a peppercorn-size fuel capsule. Heated to millions of degrees, the gold emits x-rays that vaporize the diamond shell of the capsule. The blasted diamond implodes the fuel, compressing and heating it.”
Great so we can produce a net energy gain by VAPORIZING DIAMONDS AND GOLD
Rolling on the floor laughing, limitless energy as long as you have lots of DIAMONDS!
I was merely dismissing the concerns about lack of hydrogen, or the energy budget of obtaining hydrogen, say by electrolysis. This demonstration is not remotely practical, but the net energy obtained by nuclear fusion dwarfs by more than nine orders of magnitude the energy expended obtaining hydrogen, the most common element in the Universe, and quite abundant on earth. Over 80% of all atoms in the Universe are hydrogen.
