Chemical engineers from Switzerland’s École Polytechnique Fédérale de Lausanne have created a prototype device that can produce hydrogen fuel from the water found in air.
Inspired by leaves, the device is made from semiconducting materials that harvest energy from sunlight and use it to produce hydrogen gas from water molecules found in the atmosphere. The gas could then, potentially, be converted for use as liquid fuels.
U mentioned above it's a prototype device. When will it be commercial device?
