Cars can become more effective

Researchers have invented a new material which will make cars more effective, transforming heat of an exhaust of the engine in an electricity. «The similar technology can work with generators of capacity and thermal pumps», - the head of the project Joseph Germans (Joseph Heremans) speaks.

Scientists name similar materials "thermoelectric", transmits IT Day. Materials can be divided into groups by efficiency of transformation of heat in an electricity at certain temperature. Originally the most effective material was comercially used in thermoelectric generators of capacity. It was an alloy of telluride of the lead, alloyed by sodium. Its efficiency of transformation made 0,71. The new material telluride of lead alloyed by thallium, has efficiency 1,5. It more than in 2 times exceeds the previous indicator.

The most important, that the new material is most effective at temperature from 230 to 510 hailstones. On Celsius – usual temperature of work of generators of capacity and engines of cars.

The majority of experts considers, that only about 25 % of energy from the petrol engine is used for car movement whereas 60 % are spent for heat which large part it is useless spent, getting to an exhaust.

“The thermoelectric system can“ seize ”a part of spent heat”, - speaks Germans. «It as can become useful addition to the car as it has no moving wearing out parts and does not break».

“The material does all work. It makes electric capacity, as well as any other generators, however, in quality of" a working liquid »it uses elektronyi, instead of water or gas, creating an electricity is direct. As the thermoelectric system is not enough in the sizes”.

The principle of work of a material consists that such elements as thallium and tellurium can interact at kvantovo-mechanical level, creating a resonance between elektronami thallium and elektronami in lead telluride, rasplozhayuschimisya in communications between atoms.

Researchers have found out, that efficiency of transformation of heat in an electricity at temperature nearby 230 hailstones. Celsius makes 0,75, that is close to efficiency of telluride of the lead alloyed by sodium, however at temperature above this figure, efficiency of a material increases to 1.5, reaching the best point at 510 hailstones. Celsius.

Germans and its colleagues continue to work over this applying for the patent, technology.

“We hope to go further away. I think, quite probably to apply all our knowledge received at studying thermoelectric nanotehnologii, to raise efficiency still several times is the purpose which we before ourselves have delivered”, - speaks Germans.
