Artificial leaf gets some new tricks to make it more functional
Scientists have created what they have called the world's first practical "artificial leaf." The goal of the leaf is to supply electricity in developing nations and remote areas without access to power.
Two important new features have been added to the artificial leaf including the ability to self-heal damage and to produce energy from dirty water. Daniel G. Nocera, Ph.D., a scientist working on the project, says that the artificial leaf mimics the ability of a real leaf to create energy from sunlight and water.
The artificial leaf actually looks nothing like a real leaf and is instead made of a catalyst-coated wafer of silicon.

When the catalyst-coated wafer is dropped into a jar of water and exposed to sunlight, the catalysts in the device break water down into hydrogen and oxygen. Those gases bubble out of the water and can then be collected for use as fuel for a fuel cell to produce electricity.
"It's kind of like providing 'fast-food energy,'" Nocera noted. "We're interested in making lots of inexpensive units that may not be the most efficient, but that get the job done. It's kind of like going from huge mainframe computers to a personal laptop. This is personalized energy."
Their artificial leaf also promises to be cheaper to produce than some similar products that used costly metals and other materials. The artificial leaf is also expected to be inexpensive to mass-produce.
Researchers from North Carolina State University have also been working on
in the past.

Seems pretty cool but I'd like details and price. Maybe a buy one donate one scheme like they did with those soccer balls?
