I think it would be neat if they used this to make a generator.
Such as in controled cobditions clouds can form inside rooms. Through a chim process would it not be possible to creat a lightning storm inside the room? So that you are creating power over a large area via lightning. If this is possible you could also use thermodynamics to power something else, or even provide heat for the whole area being powered.
It was just a side thought I had today, and I think it would be really cool, and could if possible replace some power sources.
