Floating 'artificial leaves' that generate clean fuel from sunlight and water

Researchers from the University of Cambridge have developed floating "artificial leaves" that can generate clean fuels from sunlight and water. The ultra-thin, flexible devices take inspiration from photosynthesis, the process by which plants convert sunlight into food. The lightweight leaves can float on water, allowing for the generation of sustainable alternatives to petrol without taking up land space. The artificial leaves have the potential to be used on polluted waterways, in ports, or even at sea, helping to reduce the global shipping industry's reliance on fossil fuels. The development marks the first time clean fuel has been generated on water, according to the researchers. (University of Cambridge)
