Cold Fusion
If there is one thing every government wants to get their hands on in this world, it’s cold fusion. What is it and what makes it so special? We’re glad you asked, mysterious reader! It is merely a type of nuclear reaction that can occur at or somewhere near room temperature. This obviously differs from supposed hot fusion, which actually does happen inside stars naturally.

It can also happen artificially through hydrogen bombs, as well as potential fusion reactors that are under massive pressure at millions of degrees. As of now, cold fusion unlike other types is hypothetical and thought to be pretty much impossible. Ever since the Cold War, there were several experiments attempting to understand and invent some type of cold fusion. It would quite literally solve the world’s energy problems and do so in a clean way.
