    10 billion? The government had to shut down over 5 billion.

  • Michael Ferrando

    We could more than likely create that type of energy but in order to "bottle a star" the hardest part is going to be keeping it from destroying the earth. If something that was smaller than a star but had the same type of energy output was made, itd be extremely challenging to harness it. Since its prolly gonna melt every single type of matter that it comes into contact with.

      I don't think we would risk building a fusion reactor with a similar power output to the sun though.
      Firstly, that would cost way too much energy. In order to actually make fusion happen artificially, you would need a lot of energy start up. That's why we aren't using it that much.

    Tritium is expensive because they are used in nuclear warheads, and building nuclear warheads is very, very expensive...
    Why don't they just dismantle the warheads and stop building them for more productive use of resources, especially tritium? Politicians all over the world say that they love peace, not war, and they never stop preparing to fight! How ridiculous things are in this planet...

    The problem with Fusion is so clear here: "If... then maybe... might... possibly... perhaps... On the moon."
    This sounds like: "uncertain... unlikely... probably not... out of our current reach... not 0 waste... extremely expensive."
    If we need to make a permanent moon base for this to work, then it won't work, because other methods that are already proven, it'll be too late once we get there.

    A fusion reactor 😂😂😂 scale the mechanical fusion device to the fusion energy needed per task and eliminate the old dumb concepts of entropy and classical physics. Accept that the only constant is change. The only concept of realitivity is what is it relative too and quit dividing all that we have learned over 2000 years into smaller categories. Learn how to direct energy like an orchestra. Be the Mozart of physics.

    Do not get me wrong, I am all for clean and efficient innovations, but we have to think critical. So we start mining helium 3 on the Moon, and we will mine and mine....and mine. In the end, we are wasting the Moon for Helium 3 just like we wasted Earth for mining coal. Basically, He3 is a fossil fuel as well it would not regenerate, or only after a long time. And when we use Water, is it then gone forever? It would be a pity draining the Oceans for "cheap energy".

    Failure. Until we figure out how to get the pressure up in fusion reactors to reduce the energy cost, it's not gonna happen. It's been 20 years away for 50+ years now.
    Sidenote: nuclear breeder reactors can be used to extract the excess radioactive energy from nuclear waste and convert it to usable energy. Not only do we get more energy from it, it also cleans up the nuclear waste we have lying around and makes it inert. It's also cheaper than blasting the waste into space or straight up burying it because of maintenance costs. We also have the tech now already and it's being looked at being used again now that it's alternative of enrichment has been fully used already.

    Just want to chime in and say that conventional salt loop reactors cannot melt down either, and they have very little waste. They have been around since 1986. Altho most operational nuclear plants today was built in the 1970's and thus can melt down and does produce a lot of waste (Fukushima for example)
