Dear David,<BR> <BR>This does not exactly answer your question in the units you are looking for, but colleague at the University of Wisconsin-Oshkosh had Cladaphora analyzed as a biofuel and found it to have a fuel value better than pine, but a bit less than oak. I can probably get the exact numbers. He is interested in the health of the Great Lakes, where Cladophora is greening over the typically oligotrophic waters, and was looking for options to get it cleaned up. This seems to support the DOE claim rather than refute it given its 'weed' status and growth rate. Growing an oak tree to harvest takes a good deal longer than a few warm summer months.<BR> <BR>Arlene Haffa<BR><BR>----- Original Message -----<BR>From: photosyn-request@oat.bio.indiana.edu<BR>Date: Sunday, March 23, 2008 10:04 am<BR>Subject: Photosyn Digest, Vol 27, Issue 1<BR>To: photosyn@magpie.bio.indiana.edu<BR><BR>> Send Photosyn mailing list submissions to<BR>> photosyn@net.bio.net<BR>> <BR>> To subscribe or unsubscribe via the World Wide Web, visit<BR>> http://www.bio.net/biomail/listinfo/photosyn<BR>> or, via email, send a message with subject or body 'help' to<BR>> photosyn-request@net.bio.net<BR>> <BR>> You can reach the person managing the list at<BR>> photosyn-owner@net.bio.net<BR>> <BR>> When replying, please edit your Subject line so it is more specific<BR>> than "Re: Contents of Photosyn digest..."<BR>> <BR>> <BR>> Today's Topics:<BR>> <BR>> 1.
