Artificial Leaf That Produces Fuel From CO2 And Sunlight (HIMANSHU GOENKA, 08/01/16, IB Times)

[S]cientists from the University of Illinois at Chicago (UIC) have created a solar cell that converts atmospheric carbon dioxide into a usable fuel.

"The new solar cell is not photovoltaic -- it's photosynthetic," Amin Salehi-Khojin, assistant professor of mechanical and industrial engineering at UIC, said. Salehi-Khojin, who is also the senior author of a related study published in the Science journal, added: "Instead of producing energy in an unsustainable one-way route from fossil fuels to greenhouse gas, we can now reverse the process and recycle atmospheric carbon into fuel using sunlight."

The new solar cells can remove carbon dioxide, or CO2, from the atmosphere -- like trees do -- and farms that use such cells as artificial leaves "could produce energy-dense fuel efficiently," according to the UIC website. The fuel produced by the cells is "synthesis gas, a mixture of hydrogen gas and carbon monoxide," which "can be burned directly, or converted into diesel or other hydrocarbon fuels."
