A long time ago, there was some (theoretical at least) effort to see whether UV lasers could be used to create an ionized channel over a long distance. Hi Guys, One has to wonder about the consequence of double jeopardy standing beneath that antenna (HAARP experiment) or holding the laser. Think insurance covers this? Supply shop foreman (perplexed): "Another laser? What happened to the last one?" Tech (smoke curling up from clothes): "ummmm, burned out real quick-like. Could you hurry? They say more rain is on the way!" 73's Richard Clark, KB7QHC Well, I could easily imagine a laser protected within a large conductive lightning rod. All you need is a 1/" hole in an otherwise well-shielded structure. Maybe a bit larger to allow for pointing, or you could put some optics safely outside the rod. Regarding the RF excitation, I assumed that a single-point source would be dumb, because the best ionization path would be right back to YOU. But an array of exciters, electronically steered to create a sufficient power density at a focal point, is a lot smarter. Again, I don't know if the technique would work, but an electronically steered (more like focusing) array would be one way to do it. One poster said that the ionized channel might blow away in the wind. Maybe a quick system could "paint" an ionization channel fast enough. Maybe a system could detect and take advantage of leaders, to create a shorter path. Ed wb6wsn |
