As early as the 1930s, Michael Faraday discovered that changes in the surrounding magnetic fields would generate electrical currents in the wires. In the 1890s, Serbian scientist Nikola Tesla applied for the first patent.
Unfortunately, this research has been delayed for a century. The biggest obstacle is the low transmission efficiency and danger. Electromagnetic radiation is only suitable for transmitting information and is not suitable for transmitting energy. Because radiation is not directional, energy is wasted in useless space. Some people assume the use of directional electromagnetic radiation, such as lasers, but they are not very operative and extremely dangerous.
