Can we harness the energy in lightning?

Paul Anderson  asked the Naked Scientists:
   
Hi Chris and team,

Before  I forget this, I shall mention it.

I just saw your article on lightning.

I have often wondered about whether that energy could be used. Could it be collected by satellites and then discharged at a particular time as they pass over a land based receptor station?
 
Regards

What do you think?

Maybe. I've never really thought of it...

Surely the problem with harnessing lightning energy is being in the right place at the right time...

Predicting a storm isn't too difficult. The satellites have been able to predictn days to come of weather...

how about predicting strikes? How are we on that?

no need to predict.
if you want to attract it.
YOU need charge.
and very big heights to place it.

It's not that hard. If you send up a small rocket that unspools a small wire, the lightning will be happy to use the path to get to ground (although, technically, it's the other way round).

The problem is figuring out a way to store the large amount of energy received in a very short time so that it can be converted into useful work.
There ain'ta no sanity clause, and there ain'ta no centrifugal force ćther.

It could be done but it would cost a ridiculous amount for the small amount of energy captured.
In a way it is captured, Nitrogen in the atmosphere is oxidised that acts as a fertiliser for vegetation.

I'm sure there is some way.
