    I was wondering about the possibilities of using the Stellar fusion porccess, or Hydrogen fusion for power on earth. Would it be possible to create a minture star and use it for power?

    There are programs, ongoing for over thirty years, to develop such capabilities.

    The project ITER is currently the most ambitious attempt. Although the process of nuclear fusion is employed here, the details are completely different to the fusion in stars. Up to now, there is no technical solution to produce a self sustained fusion reaction. The nice thing with stars is that they regulate themselves by gravity. This is not possible on Earth, because you need huge amounts of gases. It is no coincidence that stars are so huge. Instead, it is tried to contain the plasma inside strong magnetic fields.

    ITER uses a barbaric forceful method that currently cannot even have its energy extracted. This is not to say that it does not use extraordinary technology....but it is like using antimatter in a fuel combustion engine.

    The normal sequence is crawl==>walk==>run. It seems to work in every field of science in particular and life in general.

    I basically agree with you. But I do not understand, why so little effort is made to use the big and safe fusion reactor that we already have - the sun itself.

    One Fusion plant could power all of Canada, thats around 31 million households.

    Stars are hydrogen and helium. I suspect that fusion reactors might work better with the addition of some helium as a catalyst.

    Helium is the end product of the Hydrogen fusion reactions. It has no catalytic function.

    The fusion process currently tried in lab style reactors is different from what is going on in stars like the sun. In reactors, hydrogen isotopes are used for the fusion process, while in stars a couple of catalysts help in the fusion process.

    lots of methods like this are already available, the problem is either, rich people don't want them to happen like with a hydrogen car, it was invented decades ago, but never refined because it would put oil compainies out of buisness,

    or in this case its too expensive, the power needed to created a miniature sun would porbably cost the earth and more, therefore it's redundant to create one simply to power canada (which we don't like anyway)

    Cars running on hydrogen do not use it for fusion. You know that, right? Fuel cells apply a chemical bond of hydrogen an oxygen.

    I've heard it's not that hard to fuse Helium 3, but it's only found abundantly on the Moon.

    It's actually harder to make helium-3 fuse than to make deuterium and tritium fuse, which is why almost all fusion reactor research is focused on deuterium/tritium fusion. The advantage of helium-3 is that even though it's harder to make it fuse, it's also somewhat easier to capture the energy that's released in the fusion process, so it might still be overall easier to make a reactor the produces more energy than it consumes with helium-3. But we can't even really get deuterium/tritium reactors fusing well, so it will probably be a long time before helium-3 is useful to anyone.

    Oh my god I am so sorry, I don't even remember typing that




    oh and dishwasher I know it's not fusion I was simply using an example of why it might not be universally done

    No worries!
