MIT has come up with a wireless way to power laptops
A group of scientists from the Faculty of Physics and the Faculty of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), together with the Institute for Soldier Nanotechnologies (ISN), demonstrated the possibility of transmitting electricity over a distance.
In an experiment that followed theoretical calculations, the scientists managed to “light” a 60-watt incandescent lamp located seven feet (more than two meters) from the power source. The MIT group called the concept of transmission of electricity over a distance WiTricity (from two English words: Wireless, wireless, and elecTricity – electricity). You can read more about the development of scientists in the June 7 issue of the electronic journal Science Express.
The very idea of transmitting electricity over a distance has long been realized and has been used in various forms for several centuries, and in recent years devices have been invented that allow, for example, to charge a mobile device by placing it on a charging surface. However, the novelty of the work of MIT scientists is that they were the first to come up with a way to transfer enough power to remotely charge the same mobile devices, thus realizing the dream of science fiction writers about transmitting electricity over a distance without wires.
WiTricity is based on the coupled resonator approach – unlike conventional radio waves propagating in all directions, as a result of which their intensity decreases in proportion to the square of the distance, scientists propose to use two oscillators with a very close natural frequency, connected to each other mainly by a magnetic field.
The experiment used two copper coils, one of which is connected to a power source. Instead of emitting electromagnetic waves, the self-resonant source coil generates an alternating magnetic field, the strength of which changes with a frequency of several megahertz. At the output of the receiver coil, tuned into resonance with the magnetic field, a potential difference appears sufficient to connect an electric lamp. An important difference between the created system and, say, a conventional AC transformer is that the receiver and the source are remote from each other at a distance many times larger than their own dimensions, which is precisely achieved using magnetic resonance (according to scientists, at a distance of two meters the value of ordinary, non-resonant magnetic induction, a million times less). There is no wave radiation of electromagnetic energy.
Generally speaking, the WiTricity design does not allow the transmission of electricity over very long distances – the smaller the receiver coil, the less of the magnetic field it will collect and, as a result, the less efficient. At the same time, for coils the size of modern laptops, it is possible to transmit a sufficient amount of electricity over a distance of several meters, which allows the laptop to be powered from a stationary power source installed in the room without wires.
