Scientists have found a more efficient way of converting heat into electricity

When talking about how to make existing power plants more efficient, often you are asked to solve through the useful heat produced too. Heat is produced in almost all coal power plants, hydro power stations, cars and even your refrigerator, which spends a significant amount of energy reduction it produces heat. If you find a way and start to use that excess heat to produce electricity, we could not only seriously to save on production, but also significantly reducing the consumption of fossil fuels. However, this issue has always been very complex in the solution.





Recently a group of researchers from the University of Houston, Cambridge, State University Morgan and other institutions have created a new material that can become an important step forward in the thermoelectric method of energy production. New thermoelectric material capable of providing twice the output power compared to conventional materials used today.

The effectiveness of termoelectrica is customary to calculate the expense ratio of their output power. Most of the materials used can be considered "effective" if the ratio of the output power is about 40 points. Created by the same team of scientists a new material consisting of an alloy of niobium, iron, antimony and titanium, has a power factor of 106.





This means that the new material is capable of 1 square centimeter square to produce 22 watts of energy, while the efficiency of other termoelectricos shows the level of 5-6 watt power output. Remarkably, the main interest here is not greater efficiency, but that new material can be an excellent solution for production huge amount of excessive heat. For example, all those coal fired power plants. Use it at the same time can increase the profitability of such systems and this seriously help in slowing down climate change caused by atmospheric pollution. published
