Sounds like the same old idea in a new dress. Several years ago two girls went hiking at Great Sand Dunes. When they didn't come back, searchers went looking for them. They found both bodies in the sand, dead from a lightning strike. One of the girls had a camera. When it was downloaded, the last picture was of the other girl, her hair standing up due to static. The strike killed her maybe a second later. I've seen the picture; it's used as part of a lightning-safety program. So, I suppose, we'd better stay away from cameras, too.

Just Dave Posted June 29, 2011 #3 Share Posted June 29, 2011 Aaaaa no, antenna can attract lighting not a storm lol. If you stand in a plain and its raining and you have for example a cellphone, you are most likely to be hit by lighting. See lighting is attracted to higher positioned metal alloy compound. For short lighting always tries to find the quickest way down and metal is its favourite route. If you are in city at ground level there is maybe a 0.000001% that lighting will hit you. If you go on a skyscrapper there is like 75% that you will be hit, if you hold to any metal stuff like antennas or metal instalations that chance rises to maybe 90-95%. The higher you go less safer you are. . Im electrician and i could explain much more easier in my language. So i hope i was in any help :s Link to comment Share on other sites More sharing options...
MID Posted June 29, 2011 #4 Share Posted June 29, 2011 I think someone's concentrating on the danger of using a cell phone in a thunderstorm area when really, any object in your hand which contains metalic parts is a conductor. For that matter, you are yourself a pretty effective conductor without metal in a thunderstorm. Being out in the nearby vicinity of one, being in a field, being under a tree, paints a target on your back. Whip out a cell phone and decide to talk to someone and you've likely increased your already decent changes of taking a strike, if one's around you. Thunderstorms are dangerous fellows. In a house, in a plane (flying away from them--trust me, being in one is not an experience you want to repeat), and inside a car are safe places. Outside, with a cell phone to your ear? Nah. Not me... I don't think anything attracts storms,. But the electricity in them is attracted by some things...conductors. Link to comment Share on other sites More sharing options...

MID Posted June 29, 2011 #6 Share Posted June 29, 2011 Can radiowaves cause a drop in air pressure? No mechanic I know of associated with radio waves can cause drops in atmospehric pressure. Less air in a mass can do that. Link to comment Share on other sites More sharing options...
oly Posted June 29, 2011 Author #7 Share Posted June 29, 2011 "Dr. Vonnegut, the weather physicist, suspected that tornadoes are not driven by air pressure, but instead that they are a form of electrostatic motor. I've recently heard that someone experimented with this idea by directing streams of negative and positive charged wind at each other, and a tiny tornadoe actually did appear. This suggests that a science-fair "tornado chamber" could be built which is based upon high voltage, with no fan needed. Make a plastic "tornado chamber", put thin wires across two of the intake slots, and connect a high-voltage power supply across the wires. One would generate a stream of negative air, and the other would be positive. The streams would attract together and with luck form a vortex in the center of the chamber. Or, if this didn't work, maybe we need one wire down the center of the chamber, and an opposite-polarity wire on each intake slot. Repeat the experiments using dry air and humid air to see whether polarizable gases play any role. To increase the charged-air emission of a thin wire, it helps to position a grounded rod or plate nearby and parallel to the wire. (Thin wires, if connected to high voltage, act as a "sharp edge" and will emit charged air.)" http://amasci.com/freenrg/iontest.html Link to comment Share on other sites More sharing options...
oly Posted June 29, 2011 Author #8 Share Posted June 29, 2011 Same site... "HIGH WIND-CHILL FACTOR: Charged air should attract itself to any grounded metal object (and be discharged as the ions touch its surface.) But objects normally have a "boundary layer" of unmoving air which adheres to their surfaces. This air acts as a thermal insulator. It is stripped away by high winds (above 50MPH generally), and this is the origin of the "wind-chill factor". Even when flowing slowly, ionized air has maximum wind-chill factor, since it dives right down to a conductive surface and penetrates the boundary layer. If a gentle stream of charged air is directed at a red-hot metal object, the stream of air will cool the object as if its velocity were around 50MPH! Charged air causes anomalous cooling of hot objects and anomalous heating of cold objects (but only for conductive objects. (aluminium dust?) Insulators would quickly gain a surface charge and thenceforth REPEL the charged air.)" Link to comment Share on other sites More sharing options...
little_dreamer Posted June 30, 2011 #9 Share Posted June 30, 2011 How would this apply to a lightning rod on a building? Wouldn't that attract it like a radio antenna? Link to comment Share on other sites More sharing options...
