This is why a lot of the high power transmission lines now use direct current rather than alternating current. There was just too much induction loss.
Our power company in B.C. is cheap, they don't want to spend the money to change. And besides which, if there's a ground fault, the resulting explosion would be about the same as a somewhat large bomb going of. 500 kV x 100 kA is an awful lot of wattage, or jouleage, or whatever. Most of the power lines go 'over hill, over dale' or over farm land; farmers tend to get jest a wee bit excited if a large hole appeared in their cow pastures. Cows are covered by insurance, large holes aren't. Cattle insurance can be obtained through Moootual Insurance. -----Original Message----- From: Robert Derman [mailto:[EMAIL PROTECTED] Sent: 2008/05/27 11:14 To: [email protected] Subject: Re: [social] I am not receiving anything from this list Ian Lynch wrote: > On Mon, 2008-05-26 at 13:15 -0700, Pat McBride wrote: > >> Actually, the earth's magnetic field is generated by, among other things, >> the rotation of the plasma at the earth's core.
