Scientists combine coal waste and algae to create a new super-clean fuel

Scientists have discovered a new, clean-burning fuel made from unlikely ingredients: coal dust and algae. Coalgae is easy to produce, low in cost, burns without smoke, and researchers believe it can be make a major dent in crude oil imports. It also provides a market for reusing the 50-million to 60-million tonnes of coal dust produced annually as a byproduct of the coal mining industry. This discovery has the potential to save South Africa up to 40 percent of its crude oil imports.
