Can lightning be captured and controlled to produce steam?

Answer 1

There is a way to coax lightening to strike a given location, but the problem with controlling it is that the storm which is producing it is moving. One good strike does pack a wallop, but to convert water into a usefull amount of steam would take many strikes hitting a target over a period of time. Hence the problem with the moving storm.

Answer 2

Lightning is nothing more than really big static electricity. Man made lightning doesn't even come close to what nature produces.
Once a discharge of lightning occurs it has to recharge to do it again.

There are ways to make lightning strike where you want it to. I won't say here though, someone would try it and die.

Answer 3

Not practicable. The amount of energy in a lightning strike isn't that much, and it's too erratic to be any use.
