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.
Understand How the Mini Wind Turbine Works
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.

A study reveals the expansion of renewable energy procurement in Brazil and shows how companies are taking advantage of opportunities to reduce expenses, ensure energy efficiency, and strengthen strategic environmental commitments.
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.
