CA Swiss startup just announced a lunar lander with an engine that burns in a spinning ring.
MLet me guess, Stellar Alpina? The name sounds like a ski resort.
CThat's the one. Andrew Parsonson posted about it on Bluesky. They call the engine a rotating detonation rocket.
MA constantly exploding ring of fire. On paper it's more efficient; in practice it's a machine that tries to shake itself apart.
CThe Air Force has tested rotating detonation engines, and reports say they can burn fuel more efficiently than a classic rocket engine.
MThe Air Force, not a startup that just appeared on a space reporter's Bluesky. And the fact-check desk can't confirm any official announcement from the company.
CAndrew isn't a rando. He tracks European space, and he says the plans are out on European Spaceflight.
MI know who he is. He reports plans, not tests. Right now, this is a claim from one post.
CSo what? Most space news starts as a plan. SpaceX announced Starship years before it flew.
MAnd how many non-SpaceX lander companies have announced plans and then gone silent? I can name five from the last three years.
CBut Stellar Alpina's engine choice is actually novel. Rotating detonation could be the first real step-change in rocket propulsion since the nineteen sixties.
MStep-change? The combustion is so unstable that engineers compare it to holding a tornado in a tin can.
CThat sounds like something Elon would fund.
MHe might, but he hasn't. This is a Swiss company with no announced funding, no test stand video, no official release yet.
CYou can't both say 'no one is trying hard tech' and 'this hard tech is too early.' That's why startups exist.
MI'm not against trying. I'm against trading a blog post as a mission. Show me a hot fire, then I'll be impressed.
CFine. I'll check back in six months. But I'm rooting for the exploding doughnut.
MIf they're still around in six months, maybe they'll have at least one engine part to show.
CSpeaking of money chasing exotic tech, a funding board on X says fifty-two startups announced rounds since Monday. One name jumps out: General Compute, reportedly a hundred million Series A.
MI looked. No official announcement, no major outlet, no SEC filing. The only source is that list post by Bradley Jacobs.
CNot every deal gets a Reuters headline. We already covered Infisical's round.
MThe new part is Forbes on their Agent Vault. It brokers access between AI agents and company secrets, without handing over real credentials.
CSo it's like a bouncer who tells the AI "yes, you're on the list" without letting the AI see the list.
MSaif Ullah on X called it 'lying to AI agents.' That's a bouncer that lies for security.
CRight. And if AI agents are going to do actual work in company systems, you need exactly that kind of infrastructure. General Compute's supposed hundred million says investors think so.
MOne unconfirmed hundred-million round and one confirmed forty-million round is not a wave. It's two data points on a tweet.
CFifty-two startups, Matilda. If even half are real, that's real money moving.
MHalf of a Twitter list is a tweet, not a trend.
COkay, that's actually good.
MBut I want a lead investor on General Compute. No lead, no deal, no trend. That's how vapor rounds start.
CThe funding market has been cold for two years. A list this long might be a sign.
MOr it's startups rushing to announce before the quarter closes, all collected by one account. That's a PR cycle, not a market.
CSo you don't trust any funding news unless it's in Forbes?
MI trust a term sheet, not a tweet. One is a legal document; the other is content.
CFine. I'll watch for the paperwork. But if General Compute is real, it's a hundred million into AI infrastructure, and that matters.
MIt'll matter when it's confirmed. Until then, it's a rumor with a nice number.
CAll right, while we wait for General Compute's paperwork, here's the most honest startup pitch on Bluesky. A post from arcadus: "I'm part of a seed stage startup" — the budtender, probably.
MSo the guy at the dispensary is now a founder.
CHe's pre-revenue, bootstrapped, and his pitch deck is the menu.
MI've heard worse pitches. At least he has customers.
CThat's why I love this part of tech culture. Everyone's a startup now, even the person selling gummies.
MIt's not a startup if you don't have a logo and a valuation.
CGive it a week. Somebody will give him three million for the concept.
MAnd that's the entire funding debate in one joke.
CPretty much.
