2020 compared with 1920

I know this is silly... the kind of speculation that might be fun, but never scientific.... My theory is the 2020 decade may turn out to the most transformative since 1920 -- the decade that democratized automobiles (with the increasingly cheap Model T and highways built for them), the transformatio...

Re: ZAP Energy News

General Fusion. Is that the Canadian one with pistons focused around a sphere, with molten metal inside? That's my favorite -- from a visual steampunk point of view. As mvanwink5 also points out, most of the big players are planning to achieve at least break even or better with their machines curre...

Re: Sabine Hossenfelder on nuclear fusion

Helion already has demonstrated the direct conversion of fusion power to electric power at 95% efficiency, and further, is targeting 2024 for net conversion to electric power That's cheerful! Thanks. Do I read correctly that Helion's plans are based on Helium-3 fuel? I recall the renewed interest i...

Sabine Hossenfelder on nuclear fusion https://www.youtube.com/watch?v=LJ4W1g-6JiY She supports fusion, but believes it is much further away than popularly believed. Her main point is "Q" (breakeven) as popularly reported compares energy input to energy output when what matters is the total: not just...

Re: Question about Fukushima in 2016

Corium slag must make a complicated chemical soup. It starts with fuel and cladding at thousands of degrees... then add steel containment... then cement. In Fukushima add some salt (ocean) water. In Chernobyl add sand. And then the decay chain of the fuel. Then all that mess transmuting from neutron...

Re: Question about Fukushima in 2016

where do you think all the neutron absobing material from the control rod went? Also, how much concrete does the coreum have to burough through and what happens to all that material? Are you saying the China Syndrome is baloney because, in a worst case meltdown, the melting stops because: -- molten...

Re: Question about Fukushima in 2016

And what makes fission scary: no off switch! False. Fission definately DOES have an off switch Definitely has an off switch... meaning control rods? My point is that does not apply to tons of corium slag which will remain hot accordingly to the rules of the decay chain (at at Fukushima so hot it ca...

Re: Question about Fukushima in 2016

Wow, this discussion is great! A good antidote to the near silience about this is in the news. Thanks to you and all. There is no implication of recritiality So... no mystery why I don't see it discussed anywhere. FEAR sells and they sell a lot of it I understand that. Whenever anything dies (starfi...

Re: Question about Fukushima in 2016

"Critical" in the bad sense is a construct of Hollywood and the mass media I can't reconcile that -- a view of criticality as a continuum -- to the Slotin accident at Los Alamos (criticality by fleetingly and accidentally joining the two halves of the demon core) and the Cecil Kelley centrifuge acc...

Re: Question about Fukushima in 2016

More detailed explanations for me to ponder - thx! Interesting that Arne Gundersen's speculation about criticality may have been wrong. I am not sure why you are seemingly fixated on the word "critical". It only means that a core is producing enough neutrons to sustain its operating power level I gu...

Re: Question about Fukushima in 2016

I beleive the crack was blamed on an H2 pop in the donut. It was not due to the slag. I think there were two explosions (Unit 1 and Unit 3). I don't know which one has the crack in the cement containment. I believe Gundersen speculates the Unit 3 explosion was due to criticality. Here's Gundersen i...
