China Innovated Once Again and Is Bringing a Mini Wind Power Generator That Can Operate Without the Use of a Propeller

A team of researchers from China has developed a type of mini wind power generator capable of generating electricity using just gentle breezes and without the need for a propeller; instead, it uses ribbons.

Scientists from China have developed a mini wind power generator capable of harvesting electricity from the breeze a person produces while walking. The device, named B-TENG, promises to revolutionize sustainable energy generation from wind. The results were detailed in a recently published article in Cell Reports Physical Science.

The mini wind turbine from China consists of two plastic ribbons inside a tube that vibrate or hit each other in the presence of an airflow, eliminating the need for batteries. This airflow can be generated by a simple breath – and even from the movement of a person’s arm while walking.

According to the researchers from China, a gentle breeze of 1.6 meters per second is enough to power the device. However, it works best at a speed that ensures the two plastic strips vibrate in sync, when wind speed is between 4 and 8 meters per second.

“We placed our nanogenerator on a person’s arm, and the airflow from the swinging arm was enough to generate energy”, says Ya Yang. During tests, the equipment achieved an efficiency of 3.23% in wind conversion and produced enough power to light 100 LEDs or temperature sensors.
