  • “Longview’s plan is for laser fusion power plants, with capacity of up to 1600 MW”

    I wouldn’t have posted this article, but to chuckle at this bullshit. Let’s first get you out of the early prototype phase, son.

    Note also how they conveniently forget to mention it took 300 MJ to power up those lasers so they could release 2 MJ, and only do this once. For this approach to work, you need to do this many times a second.




  • LCOE as defined as “total cost divided by total energy” give an indication. The total costs for building & financing (which itself is 2/3 of this bracket!) is $31 billion for both units. The design life is 60 years, but is likely to exceed that to at least 80. Let’s put OPEX at $250M annually per unit.

    With these numbers we get to an LCOE of around $53 per MWh. Then again, LCOE is a financing metric which is often used for a shorter period, so in practice it’ll cost more in the first 30 years and be ‘free’ after that. LCOE isn’t a great metric if you want to look at what you’re going to pay for your power bill.



  • I say, go for it! 😀

    TerraPower has an interesting concept with the Natrium reactor, in that they combine it with heat storage in salt which is one of those things where one wonders “why didn’t I think of that?”. They had some false starts with designs in the past, but this seems a slam dunk as the technology is mostly there already, with decades of operational experience in sodium fast reactors across the globe.

    Do report back if you reach out to them. Really interested in how it goes 🙂
