A new prototype that turns the sun’s energy into hydrogen fuel could point the way to commercially viable artificial photosynthesis.
Fuel made inexpensively through artificial photosynthesis could be the ultimate renewable energy source. Now researchers at Caltech say they have built the first prototype of an artificial leaf that is both efficient and safe. They say the device, which uses light and water to make clean hydrogen fuel, could lead to a commercially viable version in the near future.
