Re: ZAP Energy News

In the slide ‘Performance scaling of SFS fusion’ in Ben Leavitt’s talk, Fuze-Q was underperforming Fuze at the same current. I don’t know if that has any bearing on my earlier comment, but quite interesting.

Re: ZAP Energy News

Do I read right 10^9 neutrons per pulse?

Seems very low, even with I^11 scaling and DD?

LPP have launched a funding round on Wefunder, at www.wefunder.com/lppfusion. There you can navigate to this pdf, accounts for the latest financial year to 30-sep-22 https://d2qbf73089ujv4.cloudfront.net/uploads/form_c/129891/remote_files/585181-RnU3fDqr1YAoopgGbHWBmHft/LAWRENCEVILLE_PLASMA_PHYSICS_...

...failed to eliminate.
I meant "failed to find", i.e. they had eliminated XYZ as causing the apparent thrust.

Re: EM Drive

Sorry, that wasn't completely random: I'd be more suspicious of fraudulent hype if they are trying to raise money at the moment. I looked on EDGAR, but failed to find anything. Probably not a public company yet. FWIW the video promo did its job, which I take it is selling their story. Most interesti...

Re: EM Drive

Does anyone know whether they are raising money or executing any other transactions prior to the orbital test?

…anyhow is better than the pure "faith" that is required to accept Dark Matter and Dark Energy.
The first BS claxon I remember going off was for ‘inflation’ in the late 70s/early 80s.

Re: Helion Energy to demonstrate net electricity production by 2024

Apropos fuel mix: DT is highly reactive at relatively low temperature; D3He needs higher temperature to become highly reactive. Might it work to use a small quantity of T as a 'fuse' to raise plasma temperature into the D3He regime? That is, start with some fuel mix D-T-He3 and expect an overall hig...

Re: Helion Energy to demonstrate net electricity production by 2024

So the radiation at the machine surface is about 1% of background after 34 weeks, if I’m right tgat background is 300 mRem/yr, and can do arithmetic.

Except it will be less, because the vessel walls will be effective shields against environmental alpha and beta radiation…???

Re: EM Drive

Quite. They will either crash and burn, or change the world: 45mN/Watt is huge.

Someone claims to have validated a 'zero fuel' thruster at 45mN/Watt in vacuum conditions, and are launching it on SpaceX: https://ivolimited.us/press-release-ivo-ltd-to-launch-quantum-drive-pure-electric-satellite-thruster-into-orbit-on-spacex-transporter-8-with-partner-rogue-space-systems/ https:/...

Re: Lawaranceville E-Newsletter

Hand to mouth hardly describes it. A founder, a scientist and an IT person. One volunteer couhd be a big boost, though i don’t speak for the company. For the only company (I can think of) studying fusion in an imploding plasma, the lack of public funding shows a shocking unwillingness to spread risk...

Re: TAE completes first tests of hydrogen-boron fuel cycle

FWIW isn’t their power plant design enormous? Like O(~100m)? 1 Mw/m^3 might be Ok. Though in any case I don’t see that having much to do with the paper’s modelling assumptions.
