Before we can begin talking about nuclear fusion we need to briefly address the potential green-ness of nuclear fission and their historical relation. Does nuclear fission have the potential to be extremely green? The answer is without a doubt yes. First, nuclear energy produces slightly more energy than a normal fossil fuel plant but without the harmful greenhouse gasses that are produced (CO2). However, nuclear fission reactions produce waste in the form of very radioactive spent fuel rods (Pu 239), which need to be taken to special containment facilities to await several thousand or million of years before becoming unharmful. So, the energy from these plants is attractive but the waste goes into the complete opposite direction that a green-minded person would desire. How do we solve this? Easy, eliminate the harmful spent fuel, and that is exactly the current trend in nuclear fusion right now. Is nuclear fusion even possible? That sounds like science fiction! Not only is it possible, but nuclear fusion has already occurred in experimental reactors over seas and new experimental reactors are being constructed as this article is being produced that will lead the way towards commercial fusion reactors.
