HJB,
Lucky guy that you got to take the class!
If you have the ability to compress the audio files into MP3's, I'd be very interested to hear them.
Sorry about the dead links. Somehow the blog program replaced parts of the URL with 'elipses' ( ... ). I went back and re-inserted the whole URL and tested it to verify that it worked, and also put in the Google search terms I used and also put THAT search URL into the page, and tested it to assure that it worked.
I also located a PDF that had a list of European Union standards if anyone wants to carry the standards reasearch further:

> One generalization was for X feet of borehole, a horizontal trench

> did they mean feet of borehole or feet of pipe in borehole
> (ie 2X: down & up)).
In this area (Portland, Oregon) the rule of thumb is 200 feet of borehole for one Ton of AC (12,000 BTU) or for horizontal trench w/ slinky, 100 ft of trench and 300 feet of slinky per Ton.
I ditto Daox, I'd really like to see the pictures also.
