Dan Brunner's thoughts on the TAE approach: https://www.fusionconclusion.com/how-taes-fusion-reactor-will-work-or-wont/ Excellent! Thanks. But its conclusions are grim: << TAE is a very curious fusion company: It has promised that its fusion power plant is just over the horizon for over 25 years. M...

I like comparing the neutral beam injection with filling a leaky bucket with a firehose while carrying it to the fire. Isn't neutral beam injection at least as old as the Tokomaks of the 1960s? (in Russia) And aren't they part of the endlessly recycled thinking in fusion -- an existing machine desp...

If I understand correctly, the fact any fusion effort using any method achieved fusion gain must be encouraging for all the other efforts. So: it *can* be done (without, you know, a bomb). So cheers for stubbornly pursuing a goal! It's been a long road for NiF and its many laser/target predecessors ...

Excellent! Thx - CK

No doubt everyone's seen this (below). I am no physicist, but.... -- isn't "chain reaction" misleading when used in connection with fusion? -- how could NiF even theoretically achieve ignition? It is a pulse device, kinda like an old school flash camera storing up a charge with capacitors, then FLAS...

Caught this with a Google "Alert." It has the right words -- fusion, boron, space, aneutronic.... "The ConstantQ Thruster uses a new type of fusion (non Tokamak) to generate propulsion." https://www.sbir.gov/node/2218177 Non-Tokamak... now I know everything. : ) Does "constant q" mean not a pulse de...

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...

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...

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...

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...
