Put this material in the kitchen and cook the kettle. You have electricity to charge the smartphone

This is the material based on the electrical current generated when there is a temperature difference. Just a difference of about 1 degree Celsius is enough to create a small current.

Recent research at the University of Utah has produced a great-looking material. It uses the temperature difference to generate energy. In practice, it allows the phone to be fully charged when it is placed on a fire.

Professor Ashutosh Tiwari's team used inexpensive, non-toxic materials to make this type of thermoelectric device.

This is the phenomenon when the temperature difference is placed on the same sheet of material, the current is generated. Just a difference of about 1 degree C to create enough electricity.

Previously there were similar devices, but they contained toxic components to humans. The new material is not only cheap, non-toxic, environmentally-friendly and at the same time providing a significant amount of energy.

Application of new material is extremely large. It can be used to create jewelry that utilizes human body heat to generate energy to run patient-assisted medical devices. Or it can be used in the kitchen, charging the phone while cooking; Utilize the heat from the car engine to generate electricity.

Airplanes can also be used to take advantage of the difference in internal and external temperature.

In addition, it can be used in remote areas of developing countries to provide electricity to people. Right now, the team has started working on new car and bio-sensors.
