See wireless charging mobile phones, cars, to check the wireless charging technology, feel not very understand, there is no god can explain it in popular, thank you. Can this technology be advanced into wireless power transmission technology, feel wireless power transmission technology is very promising to say, if it can achieve large-scale power transmission, is it possible to lay a large number of solar panels in outer space (24 hours of direct sunlight think excited), and then use electromagnetic waves to send electricity back to the Earth? There would hardly be an energy crisis, but that hasn't happened yet. I want to know is it not feasible in principle or for technical reasons? What is the energy efficiency of wireless charging?
Can develop, now the rapid development of society science and technology is the primary industry
