A little bit of knowledge can be so harmful.


Fusion and fission both work and are BOTH theoreticaly possible. Fussion produces energy energy because the resulting atom has less mass than the sum of the masses of the original particles. It ONLY produces energy up to iron. To make an element heavier than iron requires extra energy because after that the resulting atom contains MORE mass than the original atoms.

Fission produces energy because the two or more resulting fragments have less mass than the original atom. This works until you get down to iron. The energy in uranium that is released in fission came from when it was formed in the massive fusion reaction that is a super nova. Huge amounts of energy are released and that is when every atom that is heavier than iron is created. All atoms heavier than iron came from super novas.

So you can't fuse your way to uranium releasing energy all the way and then fission your way back releasing energy all the way. You can only release energy as you move towards iron. Moving away requires an energy input.

Fusion has actually been done in a controlled enviroment - but the particles involved were so hot that the scientists had to use electromagnetic fields to keep them away from the sides of the container!

Please forgive me for getting back on topic here but in Civ3 there are no "Natural" Resources, we have "Strategic," "Luxury," and "Bonus" Resources. Although I wonder what a Tritium resource icon would look like... :

Better?

The Problem is to reach the Breakeven (i.e. the poiint where you gain more energy than you invest to keep the Plasma hot enough and contained into the magnetc field) and hold it for a longer time.
It has already been reached for a very short time at the Experimental Fusion Reactor Jet in Culham, GB.

There are larger models planned (Iter for example), where the scientists want to test the Problems which occur with long term use of Fusion Reactors (one of the Problems is for example, that the Walls of the Reactor get radioactive during prolonged use because of the ionizing Radiation which is emitted from the Plasma).

It is much easier to create an uncontrolled Fusion Reaction (such as in H-Bombs) than to create a controlled one

Thrawn---Thanks for the info. I thought I heard somewhere that some island was vaporized by an H-Bomb...Maybe I'm thinking of the fake city the RUssians built to test their nuclear weapons...I always thought that was sick.

About your pic, Mystery Science Theatre 3000, right? I think I saw that episode this morning! Who would've thought old sci-fi movies could be that funny...

Edit: Typo

Yes... same here. Goto the Fav. Mod poll in the Community forums to get the joke behind this.


And yes, that was very sick what Russia did. But then, the US sprayed gas over some of our major cities (it was disclosed).

"I got a date with Woody Allen last night."

Sorry, don't mean to jack this thread. I always wondered, were those buildings solidly built, or were they just cheap wooden things. Because it they were cheap wooden things, it seems to be a huge waste of money.

Why did they need those anyway? Couldn't they see what happened to Hiroshima?
