A parabolic concentrator focuses sunlight by a factor of 3,000 onto the solar reactor, creating temperatures of 1,500 °C (2,732 °F). Inside the reactor is a ceramic structure made of cerium oxide, which absorbs oxygen from the incoming carbon dioxide and water, producing hydrogen and carbon monoxide ?" syngas. The syngas itself could be collected for use, or it can be funneled to the third unit, where it's converted into liquid hydrocarbon fuels like kerosene or methanol.
