Replying to: stevedebi (Jan 15, 2009 1:28 pm) You think lightning that has just jumped across a cloud to ground (or VV) 5000 ft gap will see any problem with the wheel to ground gap....??   The car's metal roof and "shell" is a much better conductor than is your body.....   And a farraday shield is used to block, "divert", or suppress electromagnetic waves and maybe some level of electrostatic coupling. No affect on lightning one way or another insofar as I know. Replies to this message: stevedebi (Jan 21, 2009 3:38 pm)

"   Lightning will probably follow a different course to ground if offered one that goes to the ground (like a tree) as opposed to one that is insulated by rubber.   I didn't make the claims about a farraday shield, that was a previous post.

We looked into this issue two years ago when the utility company was relocating the poles closer to the house. It is true that the correlation with cancer is weak, if it exists at all. That does not mean it won't or will happen; it only means that there are probably so many other variables that contribute that EMF is the least of our worries. Your chances of being killed in a car accident while worrying about EMF exposure are probably much greater. And don't forget about what you eat and exposure to a multitude of natural and synthetic carcinogens through various sources. And that gasoline that you put in the tank? Chock full of known or suspected carcinogens.   The EMF link appears to be related to long-term continuous exposure (bedrooms near power lines). Unless you spend all day in your car, it would be hard to duplicate.   And on the question of shielding. are the cables from the battery located outside the cabin or inside? If outside, the body will provide all the shielding that you need.

Lightning has enough voltage to jump from the car body to the ground over wet tires which may be somewhat conductive. The metal of the car body will conduct the electricity on the outside or the metal car, not allowing it inside. That is how a Farraday shield works.  It does not matter where the battery cables are inside the car. The current flows from positive and returns to the negative. It has equal and oppossite current.    A for power lines near your house, you are not in a Farraday shield unless you live in a metal building, such as a quanset hut.  Tall buildings with steel girders are also safe in lightning storms, because they are a Farraday shield
