Discover a new way to turn heat into useful energy

I thought the Mahdi

An international team from Ohio State University and other universities and institutions has discovered a new mechanism for capturing heat from the surrounding environment and converting it into electricity.This discovery, announced on September 13, 2019 in the journal Science Advances, could contribute to generating useful energy from heat Automobile exhausts, space exploration and industrial processes, thus utilizing wasted heat energy can often.

Paramagnon Thermal Electric Power
This discovery is based on small molecules called paramagnon pieces. These materials do not have full magnetic properties, but they have some magnetic flux. Magnetism is then called "Paramagnet".

The magnetic flux, called "spin", creates a type of energy called "magnet electric thermal attraction". The new discovery established this energy to capture heat from the surrounding environment such as room temperature, which was not exploited by Before.

Doubt in a traditional hypothesis
Conventional electrothermal conductors, notorious for the past 20 years, have been ineffective and unable to provide an acceptable level of energy, resulting in their limited use in very limited fields.

The team questioned the conventional notion that paramagnite is not feasible, and that heating would make no difference in the properties of the material.

The researchers proved this hypothesis wrong and were able to develop a method to design semiconductors capable of converting heat into electricity.

The role of the electron stream
Magnets are an important part of collecting energy from heat. When one side of the magnet is heated, the other side, the cold side, gets more magnetism, generating a flow that pushes the electrons in the magnet and generates electricity.

Researchers have found that the Paramagnon molecules drive electrons in only an estimated one-billionth of a millionth of a second, and this is long enough to make them able to collect and generate energy.

International cooperation
The research team includes an international group of scientists from Ohio, North Carolina State University and the Chinese Academy of Sciences. The research was conducted in partnership with researchers from the US Department of Energy's Oak Ridge National Laboratory and supported by the National Science Foundation, the Air Force for Scientific Research, and the US Department of Energy. .
