anneliese rated 3 months ago- From the page: "At the top of South Baldy Peak in New Mexico during two passing thunderstorms, the researchers used laser pulses to create plasma filaments that could conduct electricity akin to Benjamin Franklin's silk kite string. No air-to-ground lightning was triggered because the filaments were too short-lived, but the laser pulses generated discharges in the thunderclouds themselves." There's a lot of research going on at South Baldy. I can see that peak from my home, it's quite beautiful.

- please explain the benefits of wasting R&D on this. Its no doubt really interesting, but thats like saying "YAY WE FIGURED OUT HOW TO CREATE TORNADOS!" Why would you do that?

- A team of European scientists has triggered electrical activity in thunderclouds for the first time - deliberately. They did it by aiming high-power pulses of laser light into a thunderstorm. Next, they say, could be man-made lightning. Pulsed lasers represent a potentially very powerful technology for triggering lightning because they can form a large number of plasma filaments - ionized channels of molecules in the air that act like conducting wires extending into the thundercloud. This is such a simple concept that the idea of using lasers to trigger lightning strikes was first suggested more than 30 years ago. But scientists have not been able to accomplish this to date because previous lasers have not been powerful enough to generate long plasma channels. The current generation of more powerful lasers, like the one developed by Kasparian's team, may change that.
