Solar Energy Transmission

Solar energy can be directly transmitted by the reflection and refraction of sun¡¯s ray in line with the applied optics theory, or indirectly transmitted by converting into other types of energy, instead of by transportation vehicles like coal and oil.

Direct transmission is suitable for short distance with 3 basic methods: altering the direction of sunlight so as to transmit to the end-use spot through reflector or other optic component; through the light guide fiber, sunlight can be transmitted from the incidence side to another side, and the light guide fiber can be curving arbitrarily; guiding the sunlight into the indoor through reflection by employing light guide fiber galvanized by high reflected paints.

Indirect transmission is suitable for variable distance. After converted into thermal energy, solar energy can be transmitted into the indoor through heat pipe. After converted into hydrogen energy or other chemical material carrier, solar energy can be transmitted to the end-use spot by vehicles or pipeline. For space power station, after solar energy being converted into electric energy, it can be transmitted to the ground by microwave or laser.

Transmission of solar energy has associated with many complex technologies, which should be researched seriously so as to better utilize the solar energy.
