Determining the Value of Nothing...

I've often come up with many different proposals for new markets, two of which have been consulted and then patented by Tradesports.com. They were usually along the lines of a spread based death toll in the Middle East conflicts, 4 IDF=2PLO, tasteless but still a very tradeable market. Tradesports toned it down, because it was too difficult to find a precise news source for casualties(the ongoing Gaza Strip Conflict). They simply turned it into a straight bet whether or not there would be a Palestinian nation by 2005. But now, I've been trumped completely, by the new exchange for CO2. Carbon Dioxide will soon be a tradeable instrument. What the fuck? I don't know how it works exactly, but it has something to do with the emission quotas from production plants, and whether they can go over or under them and use the CO2 tonnes(lot size I guess), to hedge their Pollution Fines. I find this amazing that you can put a dynamic price on the value of an odorless, invisible, nothingness. Kinda takes Existentialism to the Extreme. Camus and Sartre would be proud gaylords.
