How can we tap the energy in lighting stroke for a meaningful purpose.

So far, lightning has not been used for power generation. Lightning does fix nitrogen which falls on the earth thus fertilizing the fields.

I googled and found that site:

Halfbakery: Lightning power generator

There are some arguments, namely;

To transfer that energy into movement it usually must be converted to magnetism. This involves channeling the strike through coils that will convert this energy into magnetic energy, these coils must be robust enough to survive the sever mechanical impulse and extreme strain on the insulation . The inertia of turning a flywheel over such a short duration will be huge.

This is a job for capacitors, big munty capacitors.

If a bassin of water would be charged by lightning, the electricity could elektrolyse it. If you were to light a spark it would return back to water only giving an explosion of power, which could drive a generator.
