  So this is basically a calutron... a huge mass spectrometer. 1940s technology, upgraded with state-of-the-now control systems, and electromagnets. A formidable engineering work, but more of a breakthrough from legislation and compliance perspective possibly.https://en.wikipedia.org/wiki/Calutron

  A few hundred thousand dollars worth of tech replacing what used to be a massive industrial investment is amazing. And I thought enriching uranium is something that counties with nukes go to extreme lengths to make it not accessible.

  I've been following SuperCritical, a new startup working on Uranium extraction from sea water. My understanding is that the process is much more sustainable than mining, which makes it easier/faster to establish a domestic source vs the permits needed for a new US based mine.https://www.globenewswire.com/news-release/2026/08/26/335139...

  Investors groups include: Neo Ventures - SE European VC group with mostly Bulgarian leadership and a diverse portfolio that doesn't mention Actinide at all; Mana Ventures - one of their companies is Flock Safety, the ubiquitous surveillance company in the recent news; Discipulus Ventures - MAGA supporting religious nutjobs from their own description in their opening paragraph [0], and from Forbes (paywalled) [1];[0] https://www.discipulusventures.com/ [1] https://www.forbes.com/sites/davidjeans/2025/02/10/silicon-v... (paywall)Interesting revival of or use of old technology to accomplish their goal. I'm not sure this belongs as a private tech company. I feel like it should be under the control of the federal government and no, I don't care what the libertarians on HN think about it. This needs to be a regulated company and process with clear reporting responsibilities and permanently disruptive penalties for noncompliance by individuals and the corporation.

  I have a bad feeling.

  They are killing the environment now. I remember this discussion some 25 or 30 years ago in serbia, e. g. depleted uranium. Well, guess some company always wants to find ways for dumping or lifting-up radioactive substance.

  This is highly dangerous, right? If a bad actor possess centrifuge technology and can divert this <20% enriched uranium, they are essentially days or weeks away from achieving weapons-grade material.This severely reduces the "breakout time" the international community relies on to detect and stop nuclear proliferation.
