Electricity from Heat: Russian Scientists have Created an Advanced Generator
OREANDA-NEWS. Scientists from St. Petersburg Polytechnic University (SPbPU) are developing a new generation thermoelectric generator, which will be ten times more efficient than its counterparts on the market. The finished product will be introduced into production by the end of 2021.
A thermoelectric generator is a small-sized device (in the case assembly it will have dimensions of 5x2 millimeters), which converts thermal energy into electrical energy. This is extremely important in connection with the global trend for decarbonization. The generator, developed by SPbPU researchers, contains a complex carbon nanostructure. When heated, quantum electrodynamic processes occur inside the structure, triggering thermoelectric generation.
"The use of a thermoelectric generator is relevant not only for domestic needs, but also for industry: for example, the device is placed on the surface of a turbine engine, which can heat up to one and a half thousand degrees, and this heat, turning into electrical energy, feeds sensors designed to monitor the state of systems engine ", - said Olga Kvashenkina.
At the same time, she noted that in household terms, the device will be able to charge devices with low energy consumption - electronic clocks, lamps, watering systems for indoor plants, etc. "In the future, we will strive for the format of portable thermoelectric chargers for mobile phones," she added.
According to scientists, the device has a high efficiency: heating from conventional batteries is enough to generate current to charge household appliances. It is assumed that a thermoelectric generator is installed near a room battery or mounted in a heating system, and the resulting electricity goes to the electrical wiring, charging small appliances. The system is safe for both the user and the electronic equipment that connects to it.
As scientists plan, the device will be financially affordable for ordinary consumers. Due to its small dimensions, it can be portable. Currently, scientists are preparing two patents for inventions. The project was implemented within the framework of the National Center for Medical Education of the SPbPU "Advanced Digital Technologies".
