Re: Dark matter theories

On an unrelated subject if you can stand the non-sequitur; is there any valid scientific reason to think that if there was a stable isotope of Element 115 it would have any unusual properties? Like "anti-gravity"? None to my knowledge. Also by logic we can infer that if indeed there was a...

Re: Z-Pinch Renaissance

Third-generation fusion fuels 3He + 3He → 4He+ 2 11 p 12.86 MeV 0 https://en.wikipedia.org/wiki/Helium-3 What about this reaction mixture? I remember hearing about it but it isn't talked about much. Skipjack already gave you good indication. I want to add that is not talked much also because it has...

Re: Z-Pinch Renaissance

Just noticed that GG made a mistake in his calculations. He assumed a neutron yield per second. I am pretty sure that they are talking about a neutron yield per shot. One of their shots lasts a few nanoseconds... Exactly. Even with revised math he still has a good point when he mention MAP requirem...

Re: Z-Pinch Renaissance

Indeed, but they don't seem to care about the differences there, they tend to generalize all the issues too much for my taste.

Re: Z-Pinch Renaissance

Looks like ZAP is hiring, some of the jobs mention their next generation (scientific break even) device: https://careers.aps.org/jobs/?keywords=employer:%22Zap%20Energy%20Inc%2E%22 I have seen your exchange of messages at NBF. I plaud your efforts to actually explain them what the ZAP Z-pinch is tr...

Re: Z-Pinch Renaissance

there are a lot of ideas out there http://www.projectrho.com/public_html/rocket/basicdesign.php#radiators Yes, but most of those ideas are just marginal improvements in respect of the needs of a human rated ship. I believe that the field needs a radical change of approach to the issue to the point ...

Re: That Salvatore Pais again... Fusion Reactor Patent

Salvatore - Saviour Pais - Country His actual name is Salvatore Cezar Pais. Salvatore (Italian for) Saviour Cezar (Romanian for) Caesar Pais (French for) Country So here you have, "Caesar saviour (of the) country". Quite a pompous name! That said, considering the total lack of any new sci...

Re: Z-Pinch Renaissance

Uri assumes D+He3 as the idea fuel for a SFS- Z- Pinch rocket engine. The Q and T/W are higher than with an engine using PB11 (which they also examined). You are totally right, indeed the pB11 has theoretical worst characteristics as a fuel, but is also the fuel that has been less investigated so f...

Re: Z-Pinch Renaissance

I believe to have read that the operation of this SFS Z-Pinch is essentially continuous because the shots come in such a quick succession. I am concerned mainly by the ability to dissipate heat load as the frequency of the pulses increases. If by any chance you get to talk to them again you might d...

Re: Z-Pinch Renaissance

The numbers are probably right, but according the way of working of the FuZe reactor is seems more to be an "Impulse ISP" than a prolonged time working engine ISP. If you get a shot every 10 seconds it still is a pretty impressive ISP value for space application, but nowhere useful to get...

Re: SpaceX News

Had a speculative wild@$$ thought today, probably can't start a POPS cycle in a Polywell, how about small bubble cavitation in the plasma center using microwaves? If you are referring to the Acoustic Cavitation effect (Sonofusion) of ORNL fame of early 2000, no one was able to ever replicate its re...
