[font size=3]Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.
The finding is reported in the July 29 issue of Science and was funded by the National Science Foundation and the U.S. Department of Energy. A provisional patent application has been filed.
Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting atmospheric carbon dioxide into fuel, solving two crucial problems at once. A solar farm of such artificial leaves could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.
The new solar cell is not photovoltaic its photosynthetic, says Amin Salehi-Khojin, assistant professor of mechanical and industrial engineering at UIC and senior author on the study.

... thus not actually removing any carbon from the atmosphere, merely
capturing some, storing it then releasing it again ... all the while continuing
to promote Business As Usual for fossil fuel consumption & extraction.
Yay for humans driven by capitalism ... "game-changing" my fucking arse ...

(13,508 posts)That carbon neutral cycle is promoting the consumption - the extraction, transport & combustion - of fossil fuels.
The "carbon neutral" fuel will be such a tiny tiny (almost immeasurably small) fraction of the total carbon fuel budget
that it will be meaningless but - by existing - it delays the forced move away from fossil fuels and actively provides
a quantity of greenwash that thoroughly outweighs the (non-academic) benefit.
I admit it is academically interesting and, in that respect, I am glad you posted it.
It is the parallel promotion of the fossil fuel industry via continued used of fossil fuel consuming vehicles that is the problem.
That is not a good thing in my book - it is another stage in the ongoing disaster.
