Before you continue reading, I'd like to say that I have minimal education in physics, and that this is a topic I'm interested in. If you don't have time to waste, please move on, and have a nice day =)
I was reading up on the Chernobyl disaster, and how Fission is so far the only attainable method of Nuclear energy, and how Fusion gives 3-4 times the power of Fission, and doesn't have near the same quantities of harmful byproducts.
So, my question is, what is preventing us from being able to use Fusion? And why are high density and temperature necessary to create it?
Again, bear in mind that I'm a novice with minimal education in physics. Thank you =)
