Will Tesla Dream Come True ??

There are many products that have begun to appear in our daily lives that are supplied with electricity wirelessly, such as wireless mobile chargers provided by smart phone giants in the world, such as Samsung, and there are some other products such as wireless vacuum cleaners provided by LG, although they have not yet spread sufficiently except It will definitely facilitate our daily life and make it easier to avoid the mess of wires that surround us every day.

There are companies that are beginning to offer solutions so that the average user can benefit from this promising technology, most notably the company WiTricity, as it provides you with a basic device that connects to the local electricity network to convert the alternating current into a magnetic field of ability compatible with the devices to be operated. On the other end - for example, on the wall of the room - there is another device that produces a higher magnetic field and in turn produces an alternating electric current that will feed the devices connected to it directly. It responds to the magnetic induction from the main device.
Obstacles and obstacles
how-it-works

All the promising ideas are finding in their way major obstacles, supporters and opponents of them, and perhaps the most prominent obstacles that still face this promising technology:
1- The ability to transfer energy over large distances without losing most of it.

If you look at the electricity network in your country, you will find that the transmission of electricity extends for very large and large distances between distribution stations and users, and until now scientists have not come up with a mechanism to wirelessly transmit electricity over large distances without significant energy loss.
2- The material cost.

Assuming that we were able to reach a technique that enables us to overcome the first hurdle, the process of replacing the wired system with a wireless system will definitely cost huge sums of money, and perhaps the solution here is in my opinion adopting the wired system starting from generation stations to the nearest distribution point to consumers and then transferring electricity to them wirelessly from the nearest Distribution point (it may be the closest column or distribution board located in homes)
3- Health damage in the long run

Certainly, the spread of the magnetic field that carries electricity more and more densely around us will have health damages to the human in the long run. Exposing the human to an amount that is not permitted leads to organic symptoms and imbalances in the body's natural processes.

Are we going to see Tesla’s dream come true with a totally wire-free world, let us wait and see, and hope that we don’t wait for the year 2040 for this dream to come true.
