Scientists at Fraunhofer Safety and Energy Technology, Germany, have devised a method to convert unwanted fuel into gas. The gas can be used to generate electricity and heat. The process uses "fluidised bed gasification" to convert the wood into gas that is cooled and used as engine fuel. Its overall efficiency is higher than burning wood and using the heat to drive a steam turbine.
