Researchers can make the oxidation reactions used in the synthesis of organic molecules cleaner by hitching photovoltaics to electrochemistry. The idea is simple and yet it has huge implications. To underscore the simplicity of the idea, researchers used a $6 solar cell sold on the Internet and intended to power toy cars to run a variety of chemical reactions. If their suggestion were widely adopted by the chemical industry, it would eliminate the toxic byproducts currently produced by a class of reactions commonly used in chemical synthesis -- and with them the environmental and economic damage they cause.
