Why so much emphasis on the negative aspects of aurorae? More constructive would be to devise ways of harnessing the solar wind. Just consider: no lossy conversion from one form of energy to another; solar wind is 'electricity'.
In the 1950s, SF writer Murray Leinster already had the idea of drawing energy from the ionosphere (for spacecraft 'landing grids').
Scientific American in 1974 had an Amateur Scientist article about electrostatic motors, which are powered by atmospheric electricity. (And how many times in history has a curiosity led on to something with rather more tangible benefits...? (http://en.wikipedia.org/wiki/Aeolipile) http://en.wikipedia.org/wiki/Aeolipile))
And recent experiments with lasers demonstrate that it is possible to open up a channel of ionized air to direct lightning (http://www.newscientist.com/article/mg21328584.200-lightning-directed-by-laser-beams.html http://www.newscientist.com/article/mg21328584.200-lightning...).
All that free electricity above us, wasted on pretty colored lights... ;-)

- diminish 15y agoAurora is like fire; taming it would serve us yes, but it is easy to predict when they will occur, and that seems a problem with continuity of electricity supply.
- fractallyte 15y agoThat's a very apt description of the problem! Technology should be developed to tap the ionosphere, where there's a fairly constant stream of electrons. I think the biggest obstacle in the past was storage: breakthroughs were needed in material science to be able to construct suitable capacitors. But I wonder if anyone's looked at this problem recently...
