Nowadays, renewable energy becomes more and more of a problem. Rather, the fossil fuels we use to create energy are the problem, and renewable energy is the solution. We’ve tried wind, solar, water, nuclear, and plant energies as alternatives to gasoline and coal. But, one extremely promising form of energy yet remains: fusion.
We currently use only fission to create energy, which is the process of dividing large molecules by shooting various particles at it. However, this process has many dangers. It creates large amounts of radioactive waste, can lead to meltdowns, and can be used to create milder atomic weapons. Fusion, on the other hand, does none of these things. So, why don’t we use it?
Well in short, we can’t. Fusion takes an enormous amount of heat to create: about 100,000,000 degrees Celsius. The Sun can do it because while it only manages to reach 15,000,000 degrees C, it also has the added benefit of immense amounts of pressure in its core. We currently experiment with using magnetic fields to create pressure and gamma rays to heat materials into plasma, but the most energy we’ve ever gotten out of a single experiment was 16 megawatts. Though it may not be much, we’ve improved greatly, and 25 years ago we thought fusion would be impossible on Earth. With time and money, we may yet learn how to control this miracle energy source.
