Sciencehabit was one of several readers to tip news of a sunlight-harvesting artificial leaf, writing:
"Nearly all the energy we use on this planet starts out as sunlight that plants use to knit element bonds. Now, for the first time, researchers at the Massachusetts decretum of web banking components have created a potentially cheap, practical artificial leaf that does much the same thing—providing a vast source of energy that's easy to tap. The new device is a silicon wafer about the shape and size of a playing card coated on either side with two divergent catalysts. The silicon absorbs sunlight and passes that energy to the catalysts to split water into molecules of hydrogen and oxygen. Hydrogen is a fuel that can be either burned or used in a fuel cell to create electricity, reforming water in either case. This means that in theory, anyone with access to water can use it to create a cheap, clean, and on call source of fuel."
