Earthing things by wiring them to a big pipe that goes underground is usually fine, just make sure it isn't a gas pipe (or runs near one). Fancy circuit breakers on earth that detect leakage and cut off are a recent innovation for much of the UK, and I'm not that old. Our physics teachers thought they were a pain in the butt as everytime someone fouled up in electronics the power would cut to the whole lab. Whether lead piping is a good choice is another question, on the upside lead piping has good resale value, being worth its weight in lead. The only overseas charity fund I'm aware of would be funded by Mr & Mrs Gates, and I think they are mostly interested in health related technology projects in the third world. -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE/DXFmGFXfHI9FVgYRAmWIAKDTdhTjjmkhK+tLxGahWlyK68ALtgCg1rSr CIdu4XaHC4qWcCj/so4rDcM= =o61J -----END PGP SIGNATURE----- -- The Mailing List for the Devon & Cornwall LUG Mail majordomo@xxxxxxxxxxxx with "unsubscribe list" in the message body to unsubscribe.
