DESTROY THE WORLD WITH A LONG PIECE OF WIRE (c)1997 William J. Beaty So raindrops form by collision rather than condensation, with larger cloud droplets touching and "eating" small ones in their paths. But I also hear that without the electrical attraction providec by sky/ground e-fields, droplets will bounce off each other rather than melding together. Cloud droplets will grow a little, but won't make the jump to raindrops. Rain cannot exist without the earth's vertical e-field. But rain within thunderstorms acts to sort the dense cloud droplets from the warm air, which allows it to rise violently, and so is a major cause of thunderstorm vertical circulation. So to some extent, rain drives thunderstorms, and if raindrops didn't form, the updrafts would be eliminated or greatly reduced. Thunderstorms pump charge between earth and ionosphere and keep the sky/ground potential maintained. But the thunderstorm charge-pump is thought to rely on the pre-existing vertical e-field between earth and the ionosphere, analogous to a shunt-wound generator whose output powers its own field coil. Stop the generator, lose the self-maintaining bootstrap effect, and it doesn't reappear when the generator is restarted. So, if the earth/ionosphere potential were removed, it would interfere with thunderstorm charge flow, and the potential would not build up again quickly. Also, it would interfere with droplet accretion, and rain would halt worldwide. Suppression of rain might act to suppress the physical operation of thunderstorms while suppression of sky/ground voltage would suppress their electrical action. My question: if one were to entirely short out the earth/ionosphere potential, how long would it take for things to right themselves? For example if I build a really big UV laser, aim it upwards, and trigger an earth/ionosphere lightning strike, will I suppress all rainfall and wreck the worldwide environment for weeks? Decades? Permanently? Is this something that could be estimated, or will I have to try it and see? Since a laser is a big project, a simple piece of wire would be preferable. How about a 50-mile long carbon fiber strand with a ceramic heatshield at its tip? If the spool was kicked out of the Shuttle, allowed to unreel, then reentered tip-first, it should induce a nice big lightning bolt and discharge the sky/ground capacitor plates. Zap, instant worldwide desert. ((((((((((((((((((((( ( ( ( ( (O) ) ) ) ) ))))))))))))))))))))) William J.
