- Abstract
Year after year, world requirements of energy are increasing and traditional energy sources are draining. In addition, in many cases these forms of obtaining energy are harmful for the environment. Therefore, we should look for renewable energy sources. Regrettably, these usually present two important inconveniences. The first one is the high cost of building the necessary infrastructure and the second the bad efficiency that they present. The idea consists of transmitting energy without using cables. This would be possible if we turned the electric power into microwaves, we transmitted it using communications satellites, and then we turned it again in electricity in the destination point. First, we could obtain energy in different ways. Then, the electrical signal obtained is modulated and sent to a satellite network. Finally, the satellites transport the wave to a destination point where it is demodulated and converted into electrical energy again. This technology could be adapted to the net of Galileo satellites because the electricity could be generated in a point of the planet and be transported to another one thanks to the global coverage of the project. The goal of the project would be to emit energy at a low cost to the remotest places of the world, providing a source of non-polluting universal electricity. The most important aim is the chance to give way of development for the third world. The paper includes four parts. First, there are definitions and a short historical introduction to wireless power transmission and solar power satellite and the election of a frequency bandwidth. Next, it includes ways to improve the electronic parts required as the transmitter and the rectifier antenna. In the third part, there are the results of different computer simulations in Matlab to calculate the satellite network required for the energy transportation. Finally, it includes the results of efficiency studies. The results obtained show than a satellite network is the best way to transport energy between two points and the use of a geostationary satellite to obtain solar energy. The overall dc to dc efficiency obtained is still less than the half of the transmitted power, but developing new technology will improve it. In conclusion, if we incorporated inside the system of Galileo satellites the necessary infrastructure to be able to transmit energy with them, we would obtain a good way to satisfy the demands of electric power for many people and give a chance to the development of the third world. The paper is dedicated to Antonio Rodotà for made Galileo possible.- Abstract document
