For the case of a windmill, the fast paced blade can get rid of the space expenses and produce more powerful radiation, which outcomes in the higher density of space charges and makes the next blade produce less powerful radiation. As a outcome, the radiation energy of windmill coronas shows periodic fluctuations. One feature in Figures three and 4 that we don’t perceive is that sources of tower coronas all the time show an elongated form oriented in a fixed direction.
