“Artificial Trees” could scrub C02 from air, then make methane for fuel..
This Science Now article describes a possible system for removing C02 from the atmosphere, combine it with electrolysis of Hydrogen from water, and make methanol fuel in a sustainable cycle. all based on cheap materials that can be produced in industrial quantity. Ideas like should be sold on the basis of being possible sustainable sources of energy. Its also refreshing to see an article about a technology like this treat like a really good idea on its merits, and not invoking climapocaplytic fear mongering…
Researchers in California have produced a cheap plastic capable of removing large amounts of carbon dioxide (CO2) from the air. Down the road, the new material could enable the development of large-scale batteries and even form the basis of “artificial trees” that lower atmospheric concentrations of CO2 in an effort to stave off catastrophic climate change.
These long-term goals attracted the researchers, led by George Olah, a chemist at the University of Southern California (USC) in Los Angeles. Olah, who won the 1994 Nobel Prize in chemistry, has long envisioned future society relying primarily on fuel made from methanol, a simple liquid alcohol. As easily recoverable fossil fuels become scarce in the decades to come, he suggests that society could harvest atmospheric CO2 and combine it with hydrogen stripped from water to generate a methanol fuel for myriad uses.
