@AlfaPT Fusion is quite awesome! The awe and scale of it is what makes it precisely so hard. To put it in perspective, to generate fusion requires to emulate conditions that of the early universe, or that of the core of a star. In essence, humanity is trying to make a controllable heart of a star, and it’s turning out to be really freaking hard. Stars can pull it off with gravity because they have unfathomable gravitational forces crushing down on them. We humans don’t have access to that level of gravity (thank goodness). So, we’re stuck trying to achieve fusion with light, electromagnetism, and quantum physics. Turns out these forces can behave like gravity in terms of generating star core-like conditions, but they really, really, really don’t want to. Using these forces to generate fusion is like forcing together two like-charged magnets. You can do it, but inevitably the magnets will push apart. In this theoretical example, the cost of keeping the “magnets” pushed together is higher than the energy that is produced by having them pushed together. Whoever can solve that problem by generating more energy than spent, will go down in history & usher in the era of near-unlimited clean energy.
