    I am 18 at the time of this comment and I'm currently going to college and I have plans to make commercial fusion a real thing! I believe it's completely possible either now or in the next coming years! I'm doing this and I'm taking the risk as I care about the environment and we need to do something I believe we as humans have a very limited time on this earth to undo our effects that will permanently destroy the lives of our children or generations to come if we keep wasting and our usual rate. I believe that a fusion reactor will fix our energy issues, and with cars starting to slowly change to more electronic means then all we would have to do is focus on waste produced by farming and food production.
    I believe in a better future for the human race and we do not have the time to do so. We don't have enough time to colonize a planet for the time being whether you want to argue about it our not, its an irrefutable fact that we are fucking everything up, and I believe that the first step to stopping this is changing our means of producing energy rather than stopping waste.
    We caused global warming and all the major effects that go alongside it. But I believe that each and everyone of us holds the potential to reverse those effects!

    • Brandon Lunch
      Brandon Lunch 21 hour ago +1

      Do it. And do it soon. I may not agree with you on the colonization idea, but if you got enough ambition make it happen. Our generation will try to hold things together the best we can until you get there.

    Good video but lacking in one critical part. A part that I haven't seen any other video cover either. We hear about all this wonderful "energy" that fusion gives off but no one seems to discuss how this energy creates electricity. Maybe do a follow up video to explain how once fusion is initiated we will be able to power our homes, offices and industry. Just seems like only half the story is being discussed.

    • Brandon Lunch
      Brandon Lunch 21 hour ago

      Nearly every reactor does this the same way, from coal to biofuel to nuclear. The heat generated from either burning or reacting your fuel source boils water into vapor which spins a turbine and recycles. That's the basis for every large scale reactor. Fission, fossil fuel, geothermal, algae, gas, probably a billion more. Do a google search or something.

  • guy dangerous

    In my opinion fusion is such a good and effective way of gaining energy, but the part about mining the moon, well, from past human experiences I can almost guarantee you that humans are gonna destroy the moon, and when that happens, Earth is also automatically doomed. So not a good idea after all if the moon is gonna get involved.

  • ZenKha

    I have a question. If in case of a fusion reactor failure, the heat is just dispersed around the surrounding air, then how do hydrogen bombs work? I know they get kick started by a smaller nuclear fission bomb, and that nuclear fusion reactions create a lot more energy, but I can't wrap my head around how these two different scenarios produce such a different outcome when they both share the "uncontrolled nuclear fusion" part.

      +Wisse Wester oh great. I almost had a half decent conversation on USclip for once. I did watch the damn video, and did my own research from more verified experts. I explained it clearly to you, said goodbye, but of course you felt the need to flaunt your insecurity instead of simply leaving it at that. Fusion energy is simple to understand. Its stored energy just like coal and wood, but its energy density is insanely high because of its atomic instability. Easy. Do some research on your own if your still somehow confused. Muted

    One of the professors in the nuclear engineering department teaches plasma physics, and she explicitly stated that she didn't believe commercial fusion to be feasible, barring some major scientific breakthrough in the field. The energy required to contain the plasma currently requires more energy to generate than the nuclei creates through fusion.

    The ego of man trying to create the power of stars on earth. And the ignorance of man trusting man to sustain the lethal radiation of a star. There’s a reason that earth has an atmosphere. To protect us from the nuclear radiation of the sun! Our atmosphere allows just enough sunlight inside earth to recharge humans with Vitamin D which is vital to the growth of our immune system. God created the perfect atmosphere to protect us from the sun’s deadly radiation and here we go trying to build that sun inside the atmosphere. Wtf smh 🤦🏽‍♂️

The geniuses pushing limits in science for the betterment of humanity while you trust your silent and unhelpful deity for answers to our own fuckups. Like a child who trusts his parents to solve his every problem. And when fusion energy gets developed and commercialized, I'm sure you'll use it just like the rest of us.
