RE: Johnny, FWIW Thanks hoov, for the informative post. Lets not forget 1 and 1/2 tons of graphite is needed for each 747 built. Solar and Windpower is a growing technology which is great for producing power, but if you want to store that power generated, graphite comes into play in a big way, with13 times more graphite than lithium needed for each lithium ion battery produced. With power grids growing at a rapid rate, more and more graphite will be needed.
