The American and New Zealand scientists have presented a prototype device that systems using solar, water, carbon dioxide and rare-earth action Cerium metal to produce suitable for use as fuel hydrogen. Experimental device splits carbon dioxide or water into hydrogen and carbon monoxide. The reaction involved the solar radiation, and cerium oxide, metal - one of the most common rare earth metals. In general, the principle of the device resembles a chemical reaction within the plant, but scientists claim that similarity is only in the initial materials - the sun, water and carbon dioxide. With silica the device collects the sunlight that falls into a cylinder covered with cerium oxide. Cerium feature is that it releases oxygen when heated and absorbs it when cooled. The device starts to work when the cylinder is fed a certain amount of water or carbon dioxide. Cerium under the influence of low temperature begins to absorb oxygen, resulting in at the output of the device remains the hydrogen and carbon monoxide. The resulting Hydrogen can be used for fueling vehicles with hydrogen-powered, and based on a mixture of hydrogen and carbon monoxide can be created, and then use as fuel synthetic fuel gas. According to scientists, the main breakthrough - it features the use of cerium. They also say that the cerium is one of the most common rare earth metal. Except hydrogen and carbon monoxide device capable of creating methane. While an experiment by scientists presented the prototype is still very inefficient. He is able to produce fuel only from 0, 8% of solar energy, which able to accumulate. Much energy is lost through the walls of the device and through the inlets. Scientists believe that the effectiveness of the device can be increased to 19%, only improving insulation and reducing the hole. And with 19% efficiency, the researchers say, the project can be commercially value. Professor of California University of Technology Sossina Haile said that this technology can be used to create transport fuel or to apply for building large power plants capable of producing electricity around the clock. However, according to Haile, the fate of such projects will depend on whether the different countries to cut emissions into the atmosphere.
