Being thus, we have that, throughout one day favorable in the terrestrial surface has a total of 2 available Kwh/m, to the step that in the space has 33,6 Kwh/m. Still it has the fact in consideration of that in the distance referring to the geostationary orbit, the solar illumination it occurs 24 daily hours, what it does not happen in the terrestrial surface. Collection of Energy The collection system consists of a geostationary satellite. According to Birth (2000), geostationary satellites are characterized for keeping a fixed position above of the Line of the Equator. For such, the orbital period of the satellite must coincide with the period of rotation of the Land, 23 h 57 min.
This objective is reached placing the satellite in a circular orbit the 36000 km of altitude on the Line of the Equator. That is, this allows the construction of an only place of reception, with respect to where the satellite always will point. For the energy collection they must be used photoelectric cells. Photoelectric cell is a component that, following the beginning of the diode, the capacity possesss to generate and electricity when reached by electromagnetic waves. Transmission of Energy The transmission must be made by means of electromagnetic waves. The band that possesss minor interaction with the atmosphere is the microwaves, that also are used for communication and in radars.
The microwaves are electromagnetic waves whose length, according to Tipler (et al, 2009), varies enters 1 m (0,3 GHz of frequency) up to 1,0 mm (300 GHz of frequency). One forms efficient of if to get microwaves is with the use of valves magnetron. In a general way, magnetrons, depending on the application the one that if destines, presents efficiencies of up to 80%, Pear tree (et al. 2002). Second Rasp (et al. 2006), the term magnetron was used to assign generating valves of microwaves, whose functioning is based on the electron capture for fields electric and magnetic ortogonais between itself.
