Thermoelectricity: Get electricity wasted heat

From the University of Arizona, the Group of researchers led by Charles Stafford has discovered a way to capture and exploit the heat wasted and convert it into electricity . So far that have developed is a theoretical model, but are confident that may be specified that this technology promises to improve the efficiency of all types of applications: cars, plants of solar energy, factories and many others up to 25 percent. Turn would avoid the emission of CFCS (chlorofluorocarbons) which weaken the ozone layer.


The designed model is called "molecular thermoelectric device" (would be a molecular of thermoelectricity device).Although there are already other methods to convert the surplus heat into electricity, this new concept promises to produce 100 times more voltage, be more economical, require less maintenance and a cleaner technology.

The key to this new technology is based on the law of duality Onda-Partícula quantum physics. According to her, tiny objects like electrons behave much as particles and waves.Using simulators on computers they "grow" a forest of molecules formed by benzene rings and trapped between two electrons. Then exposed them to simulated heat source and determined that increased amount of benzene by molecule rings, more was the amount of energy produced.


This design can help increase the efficiency of the photovoltaic cells, since excessive increase of heat reduces the amount of energy we can produce.Thermoelectric molecular device would take that heat and so become more electricity, at the same time to reduce the temperature of the solar panels   increasing their productivity.
