wow more stupid science from Riot.
Plasma requires more energy to produce than it could possibly generate. You have to heat things up to insane temperatures in order to get plasma, and where does that heat come from?
Nuclear fission is the best thing we have at the moment, and the waste from it is not nearly as difficult to dispose of as people say, not to mention the reactors themselves are extremely safe.
After fusion is perfected on a large scale, we can switch to that.
