mooseman: "The shear chaos and uncertainty from the Iranian President and their council is keeping the price up"
Well, the man HAS made some pretty irresponsible statements, that is true. I think that national leaders should be more circumspect in what they say. The question of course, is, whether we ought to take some of those statements seriously. The Iranian president is not a dictator. There are numerous, more moderate and rational forces that also come into play that we don't necessarily see in action.
mooseman: "they would use nukes when they saw fit and damn the effects it would have on the world..."
I disagree. Straight off, there is no hard evidence that Iran IS looking for nukes. Secondly, let's assume that they had them. Who would they use them against? The only logical target is Israel, and Israel is quite capable of melting Iran into a nice glass sculpture with its own nukes. The Iranians are NOT nutters. They are actually very clever and calculating people, and getting themselves annihilated I assure you is NOT on their agenda. For example, the Gulf War between Iran and Iraq came to and end after the US made overt moves to intervene on the Iraqi side. Ayatollah Khomenei, who was certainly more radical than the current Iranian leadership, backed down, saying that the Islamic Revolution was in danger of being extinguished, and that it was better to face a defeat than to lose it.
mooseman: "Shale oil, corn/cane ethanol, are fine substitutes for petro, but not for long."
True, the oil-from coal / shale solution is likewise a temporary fix. The ethanol solution is likewise only a partial solution, because we simply don't, IMO, have enough landmass to both grow adequate food AND fuel to run things at the present rate, when oil production declines. Hydrogen cells and renewable energy are, as you said, better long term solutions.
