They have 3d renderings of one. So, in VC-speak, yes.

#82The mere fact that you're proposing doing this on a moving vessel already tells me you're completely incompetent. No one has made fusion net positive, somehow building a net positive fusion reactor on a boat would be fine I guess but to suggest its better than enriched uranium is dishonest. You'll have more luck building a regular fission reactor on a commercial freighter than verify a fusion reactor for any ocean capable ship.
Have you modeled how plasma will behave when your reactor walls move tens of meters in any possible direction while rotating violently in every degree of freedom? Mind you, its not the plasma I'm concerned about. The ideal gas law keeps the atmosphere nice and steady. Its more of a combination of high magnetic field strength with salt water everywhere around the reactor that when destabilised in the slightest will cause a massive implosion.

just make a fission reactor, on land, in a pit, with a massive concrete wall between me and potential neutrons.

#83Sorry for being so naive but I need to ask: What is the difference between a startup dedicated to making "Fusion Reactors for Maritime Ships" and a startup dedicated to making "Anti-Gravity devices for Airplanes"? Since you're talking about applying a non existing technology to a specific market, swing for the fences and go all in.
Or swing for all the fences at once--"we're making fusion powered AGI for the technorapture!" Or similarly, why not faster than light space travel?

#84This is awesome— sounds hard but rooting for you guys.
Re: Launch HN: Maritime Fusion (YC W25) – Fusion Reactors for Ships
#85Cool!
Ships were the first application that came to my mind when I read about the roughly container-sized reactor by Lockheed Skunk Worls...that didn't happen.
Are you guys working together the Commonwealth Fusion Systems? JET-Size and HTS magnets sounds a lot like SPAR/ARC.

#86Fusion will never be practical. Why not put it in an application that will ALSO never be practical?

#88I think your timeline is at best optimistic. I would personally like to see fixed land based fusion power work before we start trying to build them into moving vessels.
Your claim that the shipping industry is "desperate to decarbonize" also needs a citation. From what I've seen shippers top three concerns are "how to minimize costs", "how to reduce costs", and "how to save money". Can you make this system cheaper to operate than heavy fuel oil? If not it is unlikely to gain traction.

#89Dumb layperson question: my understanding of confined plasma fusion from a while ago was that the energy flux across the enclosing boundary can not be handled by known materials without melting down. Is this still true? Not sure if you can share but would be curious to know what the "bottleneck" material is in your design as far as withstanding high temperatures/other extreme conditions goes.

As a corroboration, current hotness in cell phones is existing lithium ion tech with new silicon-carbon anodes.
