Sunlight and Carbon dioxide Can Be Used To Generate Car Fuel

Innovative “photosynthesising” technology might soon be able to generate “petrol” for cars from sunlight and carbon dioxide. Fascinatingly, solar-powered reactors can be used to convert carbon dioxide into carbon monoxide. Besides, this reactor can also change water into both oxygen and hydrogen. These two elements (oxygen and hydrogen) can be processed to produce hydrocarbon fuels. [...]
