Coal: the next Oil?

It’s funny how things sometimes turn out. Petroleum was the replacement for burning coal way back when because petroleum could be made to burn cleaner or hotter or brighter or something. Whatever the reason, it was better. Well now as we’re all starting to experience problems related to diminishing world oil supplies it looks like coal may be rising from the grave to trump oil. A process for converting coal into liquid diesel fuel was developed way back in the 1920’s in Germany and is now starting to surface as a potential source of fuel into the future. Maybe Volkswagen hasn’t been so crazy to stick with diesel engines for so long after all!
