Putin's new Russian MHD weapons explained (1st part) on HackerTube: recommended by 1 Hacker News commenter across 1 month, 2019–2023.
commentary · advanced · dated
Physicist Jean-Pierre Petit gives a long technical commentary on Russia's newly announced weapons, including the Sarmat missile, a nuclear-powered cruise missile and a nuclear MHD-propelled submarine drone.
It comes up in discussions of magnetohydrodynamic propulsion as a long explainer from an MHD specialist.

Russia has mastered the tech 30 years ago by accident, a side effect of the US trying to censor French scientists Very good, and long videos on that subject: "Putin's new Russian MHD weapons explained" (mature warning due to rare display of war/nudity pictures) ▶ this video [link]

Yet again, one mustn't go against the "american exceptionalism"[1] dogma, that's sad to hear The result of this ego-centric americanism; Russia able to develop their supersonic weapons before anyone in the west, thanks to the work of the silenced non-US scientists [2] [1] - [link] [2] - ▶ this video

> At that point, things went crazy. There was talk of Nobel Prizes (I wasn’t buying it). There were official complaints from the French embassy about French scientists not being adequately recognized. There was upset at Thinking Machines for not even being mentioned. And, yes, as the originator of the idea, I was miffed that nobody seemed to have even suggested contacting me—even if I did view the rather breathless and “geopolitical” tenor of the article as being pretty far from immediate reality. > At the time, everyone involved denied having been responsible for the appearance of the article. But years later it emerged that the source was a certain John Gage, former political operative and longtime marketing operative at Sun Microsystems, who I’d known since 1982, and had at some point introduced to Brosl Hasslacher. Apparently he’d called around various government contacts to help encourage open (international) sharing of scientific code, quoting this as a test case. > But as it was, the article had pretty much exactly the opposite effect, with everyone now out for themselves. In Princeton, I’d interacted with Steve Orszag, whose funding for his new (traditional) computational fluid dynamics company, Nektonics, now seemed at risk, and who pulled me into an emergency effort to prove that cellular automaton fluid dynamics couldn’t be competitive. (The paper he wrote about this seemed interesting, but I demurred on being a coauthor.) Meanwhile, Thinking Machines wanted to fil

Using MagnetoHydroDynamic, you can. You just have to use parietal Engine invented by Jean-Pierre Petit in 1975[1]. With this technology you can fly at Mach 8, easily.. [1] ▶ this video
