Stanford engineers are looking beneath the waves for a way to turn greenhouse gas emissions into something useful. The engineers have built energy-efficient, corrosion-protected underwater solar cells that produce energy to create a chemical reaction that converts greenhouse gases into “solar fuel”. These special cells work by combining the energy it generates with captured carbon dioxide and water in a transparent tank underwater to produce environmentally friendly fuels. Elsewhere in Canada, an “air-capturing” plant filters carbon dioxide out of the air to produce carbon pellets. If initiatives like this can be implemented on a grander scale, then we could see a significant global reduction in greenhouse gas emissions.
