I really don't think that cephs impact society at all. They might effect the environment, but society doesn't care about them as a whole. Most people don't even know what they are, or care. Things that society cares about include money, and prices on things that cost money. The environment is not a big priority in a time of war, or maybe you missed it, we're in one. Iraq is a little more important then pretty much everything that you guys are concerned about. Once New Orleans is rebuilt, Iraq is secure, and we have a new type of fuel efficiant form of travel, then people might think about what you want, but don't count on it.
