    Safely handling tritium is fantastically more complicated that the fuel of a fission power plant - I disagree with this, especially when considering the infinitely long HLW with fi…

    Nope, that's it! We do need vastly larger quantities though, on the order of a kilogram.

    Unlike what the nuclear Navy does today which is directly mechanically link the steam turbine to the propeller... we have the turbine spin a generator that creates a high voltage e…

    The customers are interested, there's really no slam dunk other way to decarbonize the industry, it's a super hard (and expensive) problem.

    Our device is larger than SPARC (~3m major radius) and less power (100MW fusion), hence the confidence in being able to solve the steady-state (repeated inductive pulses) engineeri…

    Thank you! We're probably going to have to eventually use every engineering software in existence haha for CAD, mainly solidworks and CATIA, for EM Physics modeling: COMSOL. But mo…

    With fusion, there is no Uranium or Plutonium or highly radioactive materials. The main concern is Tritium which is a categorically reduced concern from enriched Uranium (but still…

    Saw that this morning as well, it's awesome. I do think long term especially for grid applications stellarators could be great... note that their design is ~2.7GW I believe. We're …

    Thank you! Household fission reactors: my take is that from a technical perspective we could definitely do it. It's more from a proliferation and nuclear waste perspective, will it…

    We can get pretty far along! From magnetic system design, vacuum vessel, RF heating system, cryogenic system, tritium fueling, etc we can start making a ton of progress today. The …

    True there would be other land based uses for a 25MWe fusion reactor, the thing is it will be quite expensive and hard to compete on $/kWh against other energy sources... it's easi…
