To be fair, there are other problems to overcome, not the least of which is that petroleum dominates many facets of our lives and our societies. There are those people and businesses and countries that have an extreme vested interest in the stable welfare of petroleum, gas and coal. Somewhere back in this thread, someone mentioned the phrase "exogenous shock" with regards to economic policies. Well, the petroleum industry also worries about exogenous shocks. By way of example, suppose I came up with some new invention tomorrow, that with a low cost retrofit, everyone in the world could run their cars efficiently and cleanly on simple tap water, with no environmental impacts or harmful by-products. The introduction of such a device would have a profound and immediate impact on the stock market, on politics within oil-producing countries, perhaps civil disorder in some regions of the world, on individuals dependent upon the sale of gasoline for their livelihood, on governments that depend on gasoline taxes as a significant source of revenues, etcetera... The picture is fairly obvious. Therefore, politics, geopolitics, business and industry, and even individuals will do whatever it takes to protect the current system from this type of shock. Alternative sources of energy will eventually find their way into the marketplace. It will be a gradual sort of thing; no shocks to the existing system. No sudden loss of revenues to existing business... Just my opinion though... KJC
