    Thats really just a containment structure to keep two grown sayajin in there long enough that they complete the dance properly. Also this is really cool news thanks.

      Even with a nuclear meltdown which is highly unlikely, the worst case scenario is probably another Fukushima nature preserve city. And it’d take that over cancer from coal plant radiation.

      Not much else for Japan to do, with their very limited land if they want clean energy.

      Edit: actually, I misread it as fission reactor.

      With fusion, the worst case is wasted money on a failed experiment.

        I am pretty sure that fusion reactors cannot have meltdowns at all and don’t release any harmful gases as a result of fusion (Which is even better!).

          Deuterium tritium fusion releases helium-4 and a fast neutron. So most fusion schemes will involve producing radiation. However, the fuel can’t keep reacting without carefully controlled conditions so there is no meltdown risk or runaway reaction scenario. Vessel components may be activated by neutron bombardment and will still require careful handling when servicing the reactor.

          There are aneutronic fusion reactions, but they require higher energies and face problems with sourcing the fuel. For example helion energy plans to use Helium-3 with deuterium. Although even their fuel cycle won’t be completely aneutronic.

          Fusion is far safer than fission, but let’s not spread misinformation.

            Bruh…no.

            Fission happens in a magnetic field which collapses in nanoseconds after the previous reaction. What are you even talking about?

              The fuel itself won’t stay radioactive as you point out. There is however neutron radiation produced while the reactor is running. This necessitates shielding for components and personnel.

              Additionally there’s a phenomenon called neutron activation, where a non-radioactive substance absorbs neutrons and becomes a slighter heavier isotope that is radioactive. For something like a research vessel with relatively little operation time and low fluxes, this isn’t a major concern. For power generating reactors with high flux over long periods of time, this will make some reactor components radioactive. That means servicing and decommissioning fusion reactors will still require protocols to monitor and control contamination.

              https://en.wikipedia.org/wiki/Neutron_activation

              Since there’s no risk of meltdown, none of this poses a risk to the general public. So fusion is indeed much safer than fission, but you can’t just say there’s 100% no radiation. That is erroneous.

              An x-ray machine doesn’t stay radioactive when not in use, but it still produces ionizing radiation when it’s on. Fusion power is similar. The radiation produced mostly goes away instantly, but is definitely present during operation.

      Lack of scientific progress going boink. But literally nothing else
