New generator creates electricity directly from heat "A new type of thermionic generator that turns heat or light into electrical energy has been developed by researchers in Germany and the US. The new design overcomes the "space-charge problem" that has plagued previous attempts at developing practical devices. The device is about four times more efficient than previous generators and the new technology could find use in a range of applications including solar power and the harvesting of waste heat. Thermionic generators convert heat or light into an electric current by using the temperature difference between two metallic plates that are separated by a vacuum..."
