Re: Helion Energy to demonstrate net electricity production by 2024

The only important point for me in that video was the : "We have penalties to pay if we don't meet the 2028 date to deliver those electrons to Microsoft". That's an extremely powerful statement guys. If they signed a contract like that it means that they have a very strong confidence on their tech m...

Re: Avalanche Energy

Thanks for explaining. I have experience with electrical feedthroughs. But not to vacuum. They are called sparkplugs. But now I know why they work in the 20-30 000 volt range but not more. To ensure a robust flashover. I think you mean to "prevent" a Flashover. What about a porcelain vacuum vessel?...

Re: Avalanche Energy

Unfortunately, I am unable to grasp what a feedthrough to vacuum is, what it does and why it is a good thing to have. And particulary why this construction achieves such splendid performance on that key metric. To achieve Fusion one of the things that you need is an electric potential (a pressure) ...

Re: Avalanche Energy

Hehehe, only two years late ;) Still remarkable, I think. Maybe they use the same calendar as Elon Musk :mrgreen: But I would add that "Remarkable" is still a diminutive compliment for the real implications that a commercially available 300kV feed-through will have for any fusion company out there....

Re: SpaceX News

Do you understand it well? From the apparent snideness of your tone, I suspect not. But maybe I miss-read you. There was no snideness at all, I was actually trying to understand what you had in mind. Forums posts are prone to bend one's intentions unfortunately. The issue with catching at the top i...

Re: SpaceX News

The force on the ship skirt starts at a high level due to being fully loaded with propellent under 1g. It steps up by a factor of, what, three times (?) at liftoff (hardly “zero”) and climbs thru Max-Q. At landing, the force on the skirt starts at zero (ship hover at touchdown) and climbs to the em...

Re: SpaceX News

Tile survival whether on chopsticks or a pad (landing impact shockwave) is yet to be proven. Greater shock absorbing is possible with the chopsticks, still that said, Mars will have no chopsticks in the beginning. Perhaps the issue with landing shockwave & tiles is why EM has kept reentry active co...

Re: SpaceX News

Ummmm, are you talking about the BOOSTER? The booster has a proven catch process. I am talking about the SHIP. 100% of the force that accelerates the SHIP at launch goes thru the ship, and the force increases up thru Max-Q. If the SHIP skirt can take that, SURELY it can take a soft, “hover” touchdo...

Re: SpaceX News

First, the base of the skirt is already quit strong, having to take the thrust at Max-Q. Second, the original landing legs had to take the impact of the hard ground with wicked ground effects on the controllability of the rockets. Third, the landing grill will allow for both far better control of t...

Re: SpaceX News

No legs per-se, just a bit of engineering on the skirt. It's hard, very hard. You need to have shock absorbers to prevent the pressure wave generated by the landing force to propagate through the rocket shell, else the reverberating wave will make a carnage of the internal connection in the best sc...

Re: OpenStar Technologies

It seems like they are taking back from where the old LDX program was when it was cancelled. Levitated dipoles have plenty of advantages, but their weakest point is that the floating coil must be cooled, charged and launched in position during each run and will last only as long as the coil charge l...

Re: LazeraH AB - Rydberg matter fusion startup

Fusion power from the Holmlid effect in Rydberg matter. There are published articles but from what I gather on the web the scholars refuse to believe in them. From my knowledge no one was ever able to replicate the Holmlid effect except Holmlid himself. This should rise some red flags at the minimum.
