Anti-matter as another possibility
We know that when anti-matter and matter meet both cease to exist, and a tremendous amount of energy is created. I read and saw different views some saying it's impossible or ineffective, others belive that by refining the method of both production and storage it can be an effective alternative. Right now the cost of making and storage is too high. What do you think? Is it irrelevant as cold fusion, is something that will be accessible much sooner?
