In the US, scientists have found a way to create carbon nanofibers by recycling carbon dioxide, which is taken directly from the air. At the conference of the American Chemical Society presented the development of the professor Stuart Licht at George Washington University. The system operates on solar energy; through a tank filled with hot molten salt, chased a few volts. The result is a sampling of carbon dioxide, and one of the electrodes is gradually increasing nanofibers. Now the system is able to produce 10 grams of fiber per hour. The development team believes that they will be able to establish large-scale production, which will be able to solve the problem of carbon dioxide emissions. Other scientists are not so sure about their idea. "The project is easily scaled, because the whole process consumes very little energy. It is an effective way to reduce the level of carbon dioxide in the atmosphere", - commented on his discovery, Professor Licht. Nevertheless, the method proposed technology developers, cheaper than other ways to create carbon nanofibers. The material is widely used in high-tech manufacturing to create electronic components and batteries. If the value of the carbon nanofibers has been reduced, the material could be used more often. For example, they could be replaced by composite materials are used for the production of cars and airplanes. Scientists do not always refer to the idea of ​​recycling the carbon dioxide contained in the air, but so far in this area was more broken promises than really successful projects. From the air you can still do and money - microloan through the Internet is at stake, the very real prospect of obtaining funds in the case of urgent need. Dr. Katie Armstrong, working at the University of Sheffield, called the development promising, but stressed that the scale of production may have serious problems. "The carbon dioxide is removed from the air. Therefore, in order to collect the required amount of carbon required to process very large volumes of gas. This will increase the costs of large-scale production," - said Armstrong Bi-bi-si. Dr. Paul Fennell from Imperial College London praised the development, but noted that it is unlikely to help stop global climate change.
