This arcticle tells us about lightining and is it possible to use it as the sorse of energy.Lightning is a form of visible electric discharge between rain clouds or between a rain cloud and the Earth.Lightining is so powerful that contains several hundred million volts.And our maximum power for electricity is 220 volts.It is one reason why it is impossable to use lightining as an energy in our everyday life.Lightning is therefore too erratic to be useful as a source of domestic electricity.
In real life, power engineers worry more about diverting lightning away from power equipment,because youn all know how electricity turn off at the period of lightining. Therefore, researchers (mostly funded by electric companies) would like to devise a method to trigger lighting and guide the discharge to harmless spots. Groups in Japan, Russia, and the U.S. are using different laser wavelengths and powers to create conductive paths between the ground and thunderclouds. Most of the work is still laboratory based, but one group in Japan reported successfully triggering two lightning strikes using their laser system. Lightning can be very damaging. The collection systems have to beincredibly robust, which would drive up costs. Lightning is also verydangerous, making it tough on the collection system workers.
As you see it is dangerous to use lightning as the sourse of energy but maybe in future we will use it and maybe save them in the special box.
