William You are better off talking to an electrical power engineer for an answer than me. I can not explain why `small areas' would suffer from power brown-outs. The only thing I can think of is sporadic equipment failure, surging or equipment close to failure. Typically if some equipment was built with parts near to their rated tolerance it works fine until something unexpected happens. The equipment fails and everyhting is restarted, no fault is found. This happens regularly in my job working with computers. Faults often require an exact set of circumstances to be triggered. There is an effect called Electro-Magnetic Pulse caused when an Nuclear Warhead Explodes. This totally destroys all electronic equipment within several tens of miles of where the bomb went off. Not too mention the large bang and flash of light A-bombs give off as well. Very strong magnetic fields can affect electrical currents. But it has to be stronger than that naturally created by a high voltage cable anyway. What happens is that a moving magnetic field creates an electrical filed and vice versa. If a strong varying magnetic field is created near a power line it can induce a current interfering with the one in the cable. You would need the sort of magnet that powers a linear accelerator requiring several generating stations to affect a large area or a high voltage power line though. As to your cars breaking down I have no idea. Pure coincidence I suppose. I can not explain that scientifically. Before invoking paranormal explanations for something it is better to see if there is a normal explanation or whether people are seeing patterns that do not exist. Even scientists are prone to making this mistake. This is why all research is independently reviewed before acceptance.. This is one of the prime tenets of science, test it then try and disprove it. It is also important that someone else can verify you. It is not good enough in science that an explanation simply fits the facts- it must be testable, predict new findings and can be falsified. This is another prime tenet - falsifiability. Basically if my theory is correct then this should not happen. Is this then obeserved or not. If you have a hypothesis that UFO's are causing these happenings how can you test it. For starters has anyone else seen anything odd. Are `strange lights' in the sky seen everytime there is a power cut. Has there been a spate of cars breaking down for no reason.Does your car always have a flat battery after a power cut Do other explanations exist that fit the facts better. Basically it is necessary to think of a test that fits your idea and do it. If the test repeats the findings every time you know you are on to something. If not the idea is flawed and you have to go back to step one and try again. This is the grist of Science, most of it is failure and repeating experiments to make sure they work as expected. I am trying not to sound pedantic, dismissive and superior here. It is important to think about what is happening, question the reasoning and present a theory that stands up to testing. I would reccomend reading Carl Sagans' The Demon Haunted World. It's a good treatise on the scientific method and how science works. ----Admin message:------ I'd endorse that. I recommend every visitor to the MSN to track down this book in their library. It's a easy and humorous book, but the message is serious - In the modern world, NOT caring or trying to understand science and technology is dangerous for your health, income and well-being and leaves you vulnerable to all kinds of baloney! - Max Sang ------------------------
