[QUOTE]Originally posted by Nevod: [QB] [QUOTE]Originally posted by Ryan McReynolds: [qb] [QUOTE]Originally posted by Nevod: [qb]Fusion is plasma[/qb][/QUOTE]Let's just get things straight, for anyone who didn't take a fifth-grade science class. Plasma is ionized gas. That's it. It's what you get when you get gas hot enough. It's the fourth* state of matter; in order of increasing temperature, you have solid, liquid, gas, and plasma. Plasma is very real. In the sun, it is the result of the intense heat and pressure all that hydrogen is under. It is found in fusion reactors, for the few minutes we can keep them running. Plasma torches are used in some industrial applications. Boeing (I think) is even working on a plane-mounted plasma cannon for military use. * Recently, physicists have identified a fifth state of matter, the poetically named Bose-Einstein condensate. It's colder than solid, and what they used to make light slow to a crawl. So depending on how you're numbering the states, plasma could be the fifth: Bose-Einstein condensate, solid, liquid, gas, and plasma.[/qb][/QUOTE]Fusion occurs in very hot plasma under high pressures. But even very high energies of atomic nuclei can't penetrate Culon(spelling?) electrostatic repulsion. There, you need effect known as quantum tunneling to accomplish this. Quantum tunneling is ,well, 'overload' of Heisenberg equation. I know that plasma is real, but I know about my mistake: I meant plasma reactors, not just plasma. [/QB][/QUOTE]
