FUSION REACTORS (​KURZGESAGT)

​
                I have just viewed a talk about Fusion Reactors, but in my opinion, Fusion Reactors are too costly and risky to make. Although Fusion Reactors are very safe, we do not know if building a sun on earth would work.
                We already know solar, wind, and water energy is very reliable. For one, the sun is always shining, and on cloudy days we can rely on other natural energy. Windy days are not uncommon, and if the wind isn’t blowing as much, the water is always flowing. Unless all the water suddenly evaporates on earth, we’ll have power from water for millennia!
                Another reason to stick with things we already have, Fusion Reactors is costly. We don’t know how to even make one that works well yet! It’s a task of highly expensive trial and error. If we fail, we have just wasted billions of dollars on a useless chunk of machinery. After that, we must spend more money and time taking it down to recycle. I am not saying it won’t work, but we just have easier and reliable sources, too.
                Those are my reasons why I do not think we should start building Fusion Reactors right away. We must make sure it is something that we can really make foolproof, and if it fails we wasted the money and time, but need to use more money and time to take it apart.
