Re: Vortex rocket engine: lighter, more efficient, more reusable
SpaceX recently ran Raptor 3 at a sustained 350 bar. Not bad! Yes, and it's an amazing engineering achievement. I doubt they will be able to improve more without some new and radical discovery in metallurgy and material composition, and so far I do not see any in the various publications. If they c...

Re: Kronos Energy - simulations only?
News of a 30 Tesla magnet. For some reason all links are dead outside the US. Can someone please have a look and share whats going on In the news release there is no pictures nor it mention the existence of a prototype. If they indeed had built a working 30 Tesla Magnet they would not need to hire ...

Re: Greenest, cheapest battery yet, iron air by Form Energy
That's because they have also a terrible efficiency (under or around 50% if I remember correctly) and extremely slow to recharge.
Re: LK-99
I have been digging everything I could on LK-99 since the last 2 weeks. While I am still not 100% convinced there are more and more replications coming online every day now. If it proves true the real disruption will be to have identified a new working route for HTSC, and just imagine what we could ...

Re: Avalanche Energy
I hope they will publish more actual working data on their feedthrough design. I can't stop stressing what an important technological achievement this is if it does indeed work in a stable steady state at 200/300 Kv as advertised.

Re: youtube Polywell critique with response from EMC2!
Yes, I get suspicious with coincidences. Perhaps he was fishing for news? Yes, suspicious indeed. It is almost like he was put up to it, and didn't even make a good job of it. That was exactly my feeling when I said in April that there was no need from Matt to come out suddenly with such a video. M...
Re: EM Drive
That is disappointing. For skeptics it is unsurprising. There is too much good news these days so I am not starved for hopium. I am still willing not to show any skepticism and to oversee this as a simple delay if all they need is more time to revise their setup. But, should they start to ask money...
Re: EMC2 news
I am interested into that too!

Re: EMC2 in the news with DOE FPNS proposal!
By reading the PDF in details and by reading SHINE website, I think is easy to understand the situation. SHINE has contacts and some expertise, but it lacks an advanced technological framework that can give them an edge over competitors, so in truth their contribution is limited and they cannot real...

Re: EMC2 in the news with DOE FPNS proposal!
The PDF attached to the presentation has the juicy details: ● Plasma target radius: 8.5 cm ● Plasma target temperature: 500 eV ● Magnetic field strength: 2–3 T at boundary, 4–5 T on surface of coil casing ● Ion beam energy: 150–200 keV ● Ion beam power: 5–6 MW ● Fusion power output: 350 kW ● Displac...

Re: ZAP Energy News
Plus their design is very compact and it might make for an amazing space propulsion system. SJ, what method of propulsion? At this point their conversion approach is thermal. It's pretty straightforward, just let part of the fusion plasma out to act as propulsion. There was a paper from Shumlak on ...
Re: EM Drive
That was not possible until just few years ago due to prohibitive cost of sending anything into orbit.
The actual cheap access to space and the continuous cost reduction will soon make it less expensive to directly test in outer space than to test in a designed facility.
