Ethanol is currently made primarily from fermented corn, so it takes a sizable chunk of agricultural resources. The new method, presented in the Proceedings of the National Academy of Sciences, uses water, carbon dioxide, and electricity delivered through a copper catalyst.”One of our long-range goals is to produce renewable ethanol in a way that doesn’t impact the global food supply,” principal investigator Thomas Jaramillo, an associate professor of chemical engineering at Stanford and of photon science at the SLAC National Accelerator Laboratory, said in a statement.The secret to this new method is in the particular crystal structure used for the copper. The team used three types of copper – copper (100), copper (111), and copper (751) – and tested their ability to convert water and carbon dioxide into ethanol.”Copper (100), (111) and (751) look virtually identical but have major differences in the way their atoms are arranged on the surface,” said Christopher Hahn, an associate staff scientist at SLAC and co-lead author of the study. “The essence of our work is to understand how these different facets of copper affect electrocatalytic performance.”The team discovered that a particular arrangement in copper (751), where the atoms are quite far apart and with only two close neighbors, allows for the production of more liquid fuel than other types of copper.”An atom of copper (751) only has two nearest neighbors,” Hahn said. “But an atom that isn’t bonded to other atoms is quite unhappy, and that makes it want to bind stronger to incoming reactants like carbon dioxide. We believe this is one of the key factors that lead to better selectivity to higher-value products, like ethanol and propanol.”While biofuels are carbon neutral, they still use resources that could be used for food production. They also have been linked to potential deforestation in developing countries. This method might provide a truly green alternative.”The eye on the prize is to create better catalysts that have game-changing potential by taking carbon dioxide as a feedstock and converting it into much more valuable products using renewable electricity or sunlight directly,” Jaramillo added.In order to look for the best possible set up, the team aim to test the same approach on other metals to see how different surfaces affect ethanol production.

Andy Rubin, Essential CEO, Android FounderWhy I started Essential

I know people are going to ask me a lot of questions about why I started this company. Why didn’t I just travel the world, ride my motorcycle, tinker with my robots, hang out at my bakery with friends and family. And to be honest I still do ask myself that sometimes…but not too often.

So why did I create Essential? Well, my hardware engineers wanted me to talk about how we are bringing real passion and craftsmanship back into this category. My software engineers wanted me to talk about our vision for making all devices, even those we don’t make ourselves, play well together. My partners wanted me to talk about how we are using methods that could change how successful technology companies are built forever.

But the real reason is because of what happened during a night out with an old friend of mine…
