A US company has made aircraft fuel from biogas, which is gas made from cow waste. In this process, light was used to break the gas apart and then join it again. The result was fuel for planes. The company says the method uses far less energy than traditional ways of making the same kind of fuel. This could be important because it offers a different way to produce aircraft fuel.
