Japan's two successful test wireless transmission 500 meters lit LED lights

          Recently, Japan has conducted two successful microwave radio transmission experiments, the outcome is expected for the space solar power generation.

 

Japan Aerospace Exploration Agency (JAXA) 11, said the researchers used a microwave, 1.8 kilowatts of electricity (enough to start the kettle) wirelessly and accurately transferred to a distance of 55 meters of a receiving device.

 

On the 12th, Japan's Mitsubishi Heavy Industries has announced that researchers will be converted into 10 kilowatts of power microwave after delivery, the success of some of these power LED lights lit up on the 500 meters outside the receiving device. This is so far the longest in Japan's domestic success of this experiment, the power of the biggest.

 

Mitsubishi Heavy Industries, said Friday in a statement: "We are confident that this experiment shows that the commercialization of wireless power transmission has become possible."

 

Wireless transmission means transmits the electrical energy without the cable from the power generating means to the reception side technology. The biggest difficulty lies in the technology, how to solve the transmission of radio waves in the dispersion and attenuation problems. For wireless communication, the diffusion wave may be a good thing, but the wireless transmission is the opposite.

 

Mitsubishi Heavy Industries, said the technology will be used for space solar power system (SSPS). The company plans to use the technology in 2030 to 2040, the electricity generating device space obtained by microwave transmission to the ground. It is estimated that, if the diameter of twenty-three kilometers huge solar panels generate electricity in space, will be able to reach a common one million kilowatts of installed capacity of nuclear power generating unit level.

 

In addition, the technology is expected to be utilized in other areas, such as offshore wind power plant to the land transmission, dangerous areas to natural conditions as well as the transmission of wireless charging of electric vehicles and other fields.

 

Scientists said that this "one small step" may be mankind efficient use of clean energy, "a big step." Imagine a scenario: a Space-based solar power still at 3.5 million km altitude from the ground, continue to supply for the city on the ground. This transmission mode clean, safe from harsh weather and the impact of time, it will not happen the traditional nuclear power plant nuclear accident.

 

However, the ultimate realization of this vision is still a long way to go. Japan's JAXA scientists say may have to wait until 2040 or later when. There are many hurdles to overcome, such as the huge power plant into space, how to assemble and maintenance.

 

Space solar power program in the United States in the early 1960s put forward. 2009 Japan's industrial economy SSPS province began funding the project.

 

Mitsubishi Heavy Industries in 2012 and Japan's industrial economy provincial agreement, is responsible for "2012 Solar radio transmission development plan," the research work.
