Successful experiment with wind power electromagnetic radiation

Successful experiment with wind power 

Scientists have developed an antenna based on metamaterials that can generate electricity from the ever-present radio waves, Wi-Fi, radio broadcast signals, and radiation from mobile phone towers. In the form of electromagnetic radiation, these energy-filled waves are all around us. Now with a new invention, we will soon be able to operate low-cost sensors, LEDs, and other devices with the help of wind. Jiang Fengzhou, head of a research team at the University of Southern Florida, and his colleagues developed the system.

He says that because currently low-cost devices can be operated, they could play a significant role in the energy of an environmental sensor that records the temperature in the building, its structure, or the humidity in the forest. The reason is that it is impossible to go to these places and change the battery again and again. In the first phase, it generated 100 microwatts of electricity from low-intensity radio waves that could run simple devices. It has since been tested in a laboratory. 

It is kept in such a chamber, where outside radio waves were blocked. While radio frequencies were sent from only one source. According to critics, the antenna is still very large, which is being considered shrinking. However, it also generates some energy from Wi-Fi and BlueTooth signals. However, Professor Jiang believes that now is the time for this technology to be fruitful because we have special materials and technology. The day is not far when we will be able to convert the energy lost in the form of radio waves back into electricity. He added that the first specimen or prototype is 16 cm long and as wide. It can generate electricity from any frequency between radio waves of 0.7 to 2 GHz. If placed 100 meters away from the cell phone tower, it can generate 100 microwatts of electricity.
