Researchers find a new way to convert heat into electricity
When we think about ways to make existing power plants more efficient, we typically look at waste heat. It's something almost everything generates -- coal plants, automobiles and even your refrigerator loses a sizeable amount of energy to lost heat. Capturing and using this heat to generate electricity with can save money and reduce fossil fuel consumption, but capturing power from that heat has always been a challenge. Now, researchers have created a new material that could represent a major step forward in thermoelectric electricity production.
