Cable maniacs could finally see their dreams come true. A company called Reasonance has presented at CES a system capable of powering a television of about 50 inches completely without cables thanks to a wireless power transmission system.
A Smart TV without cables
The problem of cables is something that has been with us since electricity was invented. Today, wireless charging systems are helping to charge the battery of small devices by simply leaving them on a surface prepared for the occasion, but for now, the larger and more energy-demanding devices continue to depend on a power cord. current to live.
Manufacturers like Samsung have come up with special extremely thin and nearly transparent cables with which to carry power and data, but it remains an umbilical cord that many are unwilling to accept. For them, the Reasonance project aims to put an end to their demands with a 100% functional and effective product.
How does this technology work?
The Reasonance system at the moment looks more like a dockable accessory for televisions than a finished product, but the reason is simply in its premature prototyping state. Still the technology works and perfectly demonstrates its capabilities.
As you can see, the idea is formed by two large octagonal coils that are responsible for transmitting energy wirelessly in approximately the same way as the coils of a wireless charging base for mobile phones, only on a large scale.
An emitting coil is responsible for sending energy through the air to another receiving coil that is connected to the back of the TV. According to its creators, an implementation idea is to integrate the emitter coil on the wall and the receiver coil on the TV chassis itself, thus allowing the TV to be placed anywhere on the wall.
Effective and with margin of movement
Something that is especially striking in this system is its efficiency at distances, since the coils are capable of maintaining the transfer of energy at distances of up to 50 centimeters, even without being aligned. According to the manufacturer, the system is capable of offering 120W power without cables, and its operating frequency ranges from 20 to 120 Hz with an efficiency of 90%.
The future of Smart TV?
It is probably a fairly practical and effective option for some users, especially in offices and places where the screen needs to be moved from one side to another, but its success will also depend on the implantation of the emitter coil, since it will require a pre-installation that in most cases you will need a small work. Still, the idea looks especially promising.
