The device, developed at Sandia National Labs as part of the Sunshine to Petrol project, uses sunlight and steam to neutralize carbon dioxide instead of spewing the stuff up into the atmosphere. The process would produce methanol, which could be used for fuel. The downer? The engineers say it could be a decade or more before the device is available.—Gregory Mone
