Microwave power transmission is a kind of don’t wire transmission technology. This technique is the construction of space solar power Indispensable to plant.
As oil, coal resources on the earth rising increasingly dried up and environmental pollution,
Come at designated satellite stations are built in geostationary orbit, make full use of solar power.
Studies have shown that the sun radiation to the earth’s energy per hour is about 180000 megawatts, equivalent to burning 90
The one million tons of high-quality coal heat. Obviously, the solar energy is inexhaustible, an inexhaustible and pollution-free
The source. Power station 36000 km distance from the ground, can’t send power to the ground wire. Microwave lose Electricity is the process of the solar cells produce direct current (dc) can, with microwave tube into a microwave beam, By the antennas to ground receiving station, and then back into the power went out.
Is microwave wavelength between radio waves and infrared radiation of electromagnetic wave, the current should be extensively Used in the microwave oven, weather radar, navigation and mobile communication. It is different from radio and shortwave, Can smoothly through the ionosphere without reflection. Space is an ideal medium, microwave by transmitting a few Almost no energy loss, through the atmosphere of the loss is only 2%. Scientists calculated, and the same face
Product of solar battery, power generation satellite in space, by the power, is the capacity of the ground More than 10 times, this is due to hit the ground solar radiation is absorbed by earth’s thick atmosphere, reflection and scattering off quite a part of the reason.
Microwave transmission, ground receiving antenna has a very large area, its power density is lower than the safety standard, make full use of solar energy, and will not pollute the environment. Microwave transmission without erection of transmission lines,Can directly provide electricity to air ship and aircraft, can also be used to remote mountains, deserts, and islands Sending. Scientists predict that once completed space power, human beings can get energy, constantly Energy will have a revolutionary change.
