At present, the use of solar power on the ground, by the cloudy, rainy, day and night changes, the refraction of sunlight in the atmosphere, reflection, absorption, energy loss and other effects. In order to change these environmental conditions, make full use of the sun’s heat, thus, a new and bold design of a cosmic epoch-making power has been brought up in 1968, Americans Peter. Glaser proposed the idea of satellite solar power station, that the earth

Use of outer space solar power, then power microwave and laser will be transmitted to the receiving device on Earth, then the received microwave or laser energy into electrical energy for human use. Later, there was another demonstration of experts in various fields, and gradually formed a set of transmission from generation to program.

The first is power. Scientists, the use of modern space technology, in low Earth orbit satellite assembly a large power generation, and the use of on propulsion, the satellite sent to the geostationary orbit, which is 3.58 million km above the Earth’s equatorial position. This generation satellites orbiting the Earth to just 24 hours a week, from the ground point of view, it seems to hang in the air as fixed.

Installation of satellite solar huge collection of converters, in fact, like the super football covered with solar cells. This huge display area of solar cells are about 100 square kilometers, can send 10 million kilowatts of electricity, equivalent to 10 1 million kilowatts of nuclear power generating capacity. The satellite ideapad Y430 battery is a huge man-made objects, weight of 10 tons!

Satellite solar power station to issue such a strong power, must be sent to Earth to be effective. How to power back to earth? Scientists have developed a wireless transmission, using microwave technology. Microwave is a relatively short wavelength of electromagnetic waves. Microwave transmission frequency used in the same household microwave frequency is 2450 MHz. Such changes in the microwave to 2.45 billion times per second. AC wavelength is 6000 km, while the use of microwave transmission wavelength is very short, only 12 cm. Satellite solar power to issue, after conversion into a microwave, from 1 km in diameter fired Earth great dish. Microwave radio to that emitted light beam like a flashlight. Reach the earth, this thick, “Display” (microwave beam) will cover an area of 43 square kilometers, 7.4 kilometers in diameter.

7.4 km in diameter on the ground a huge antenna to receive radio from space to the microwave energy into electrical energy, you can send home the wire.

However, these satellites is only ideal in a miniature Aspire 5050 battery model of satellite solar power stations, their power is only one thousandth to one ten thousandth of the ideal value. To the construction of one million kilowatts to 10 million kilowatts of large satellite solar power station, needs of billions, even hundreds of billion dollars investment, which for any country is a heavy burden, need to work together in the world Geguo, the joint development of energy. It is expected that electricity sent from the universe.
