One direction to take this would be in the way of lightning propagation. Using super conductive fluid expelled from the exhaust of a 2 foot rocket in the proper conditions, say Florida, and you could induce a strike in a very controlled, accurate way. Launch it off a tower like done in this experiment, and you could potentially develop ground infrastructure to establish a "lightning farm" for harvesting power.
Clearly there are many problems as to how to capture energy, but this does solve some solutions. Check out their website. They have a lot of Amazing photographs taken of this working.
What do you people think?
Time to invent the world's most capable conductive material?
If you could create a massive dish, like Arecibo in Puerto Rico, of some super durable heat resistant material. It might create an irresistibly attractive single multiplied positive streamer to attract your induced lightning strike. Hopefully its unified positive attraction strength would overwhelm the forces of the misaligned flux lines which are due to the misshapen cloud undersides, and the tendency for the air (particulate matter) to force the strike in awkward directions.
Still the massive storage problem and millions O others sigh...
