What: A new solar device that imitates plant life can produce carbon monoxide and hydrogen on its own. The device uses a metal oxide known as ceria, which strips the oxygen off of carbon dioxide and water.
Who: The prototype of the solar machine was developed by researchers in Switzerland and the United States. The machine, in which sunlight heats a ceria cylinder to break down carbon dioxide and water, is said to signify an important step forward in harnessing solar energy.
The Future: The hydrogen produced by the device could be used to fuel cars with hydrogen fuel cells and to operate major energy plants. To encourage work on such solar machines, researchers believe more states must adopt a low-carbon policy that would require new methods of energy production.
