Re: National Ignition Facility

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 ...

Re: National Ignition Facility

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...

Rocketstar.nyc - "ConstantQ Thruster"

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...

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...

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...
