Commercial viability no longer a question.With the price of crude rocketing, the commercial viability of processing oil shale is coming to a pass. Critics will continue to disappear both in the U.S and Canada as consumers will have to reach deeper into their pockets. Instead of just oil companies coming under fire, governments are going to be coming under increasing pressure to find solutions. And there we are huge deposits of oil shale in both the U. S. and Canada two of the most stable countries in the world. Even environmentalists will be muted (sadly), however as long as the world demand for fossil fuels is consumed worldwide daily, I only see these oil shale deposits increasing in value. As an investor this has been my long term vision. rich47.
