Another use of field loops of this sort (which are under consideration to sail starships in the heat of the solar radiation) may be to actually move the jetstream S or N to change the weather controlled by the upper level flow, this might be achieved from planes near to the stream or with lasers or lasers from the earth, they would heat where the beams reach each other, like a concert laser light show, or in laser surgery (like the Gamma Knife) where two or more beams combine after going through outer tissue without harm to it, then they burn away tissue even to the cellular level, without anesthesia for severe illness and they are out and walking to exercise in hours. The combination of the rays without power reduction till they meet is good to save, perhaps better than the motif of magnetic fields which may spread out in the intervening room.

I saw this watch infomercial, it said it was one second in 100 years, 8 billionths of a second I said WOW! I wasn't used to 20 billionths of a second!
