wireless electricity: scientists send energy 55 meters away through air - wireless electric toothbrush

Japanese scientists at Japan's Aerospace Exploration AgencyJAXA)
1 success with microwave delivery.
A spokesman for the agency said 8 KW of the electricity reached a precise target of 55 metres outside the air.
"This is the first time someone has used a subtle directional control device to send a high output of nearly 2 KW of power to small targets via microwave, AFP quoted him on Thursday.
Although the electric kettle has only enough energy and the distance is not large, it seems to be a huge leap forward in the development of new energy.
The successful experiment could pave the way for collecting inexhaustible solar energy in space and transferring it to Earth, researchers said.
The International Space Station and other satellites have been able to collect solar energy and use it for maintenance work.
The main benefit of solar power generation in space, not on Earth, is that no matter what the weather conditions are, and no matter what time of day, energy can be permanently obtained.
JAXA has been working on space solar system projects for many years (SSPS)
Imagine a space
Solar power plants that generate energy by collecting sunlight on the stationary orbit of the Earth.
"SSPS consists of a space
Collect sunlight, convert it into a microwave or laser beam, and transmit it to a power generation/transmission facility on the ground;
There is a power receiving facility on the ground, "said chief researcher Yasuyuki Fukumuro.

Fukumuro said that researchers have now moved from the research phase to the technical demonstration phase.
"There are many technical challenges that need to be addressed before SSPS is implemented," he said . ".
"When microwave transmits power, a major technical challenge is how to control the direction and transmit it accurately from the still orbit to the receiving station on the ground.
He added: "The SSPS project saw that microwaves were transmitted from a height of 36,000 to a flat surface with a diameter of 3 km, which was" like a needle-piercing ".
Agence France-Presse quoted a spokesman for JAXA as saying that the practical application of this technology may take decades.
He predicts that the SSPS project will be launched by 2040.
The doctor introduced the idea of powering the Earth from space.
Peter Glazer was patented in 1968 and in 1973.
The project, supported by NASA and the Department of Energy, was thought to be too costly and shut down in 1980.
