This seems like a pretty good idea. 20 feet is much more space than I have to offer but, I could probably figure out a way to contain a tube-in-tube design inside a large diameter pvc pipe (6 ft long or so) capped at both ends and plumbed to create a homemade shell and tube heat exchanger. I'll have to look at the economics of this design. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
