The Japanese created a prototype of wireless charging for electric cars

Everything is good in electric cars - they almost do not make noise, do not smoke the atmosphere. But there is, of course, one serious drawback - the need to charge the battery of an electric vehicle. And if in the case of fuel engines there is no problem - there are just a huge number of gas stations now, but the network of electric stations for electric vehicles is still in its infancy even in developed countries, not to mention third world countries. This limits the scope of distribution of electric vehicles. Japanese scientists offer an interesting solution to the problem of feeding electric vehicles with energy.

The Japanese from the University of Toyohashi created a prototype wireless charger that allows you to freely transfer energy through a block of concrete 10 centimeters thick. During the demonstration test, the development team was able to make incandescent lamps glow without connecting the building's power supply lines to them. Bulbs glowed when they were separated from the source of energy.

The Japanese project was called EVER (Electric Vehicle on Electrified Roadway), and its goal was to create highways for electric vehicles with an integrated charging line located under the road cover. If the electric car does not need to constantly replenish energy, then such cars will become much more common.

Another question, of course, is it economically advantageous to build energy routes and whether such a transport network will develop worldwide. In addition, there are also purely technical problems, such as the need to find the most efficient (and economical) way to transfer energy "through the air", so to speak. But in any case, the project is very interesting.
