Bio-coal instead of Petro-coal
If you want to make your coal-fired train or power plant more enviro-friendly, then this might be good news for you. A Seattle-based company is planning to offer ““, which apparently stands for eco-coal (I think they should have called it “bio-coal”, but maybe that name is taken). The big advantage for you, Mr. Steam-Train-Engineer, is that this E-coal can be “substituted for fossil fuels, without the need for facility [or train] retrofitting.”
On a smaller scale, you can now fire-up some as alternative fuel. These are better than wood-based charcoal because they have a higher caloric content by weight and “leave no soot when touched, are easy to light and emit almost no smoke.” But I wonder if they add a flavor to food?
