After close to two years since Al's passing, his family has found his
bio-digestion materials, and have given the rights to his intellectual
property to Green-Trust, to carry on Al's work. We are in the process
of scanning and processing the documents, and will be posting them the
Green-Trust website, and as the video tapes become available, they will
be converted to cd/dvd and made available for a donation, the proceeds
going to building Al's digesters at various off-grid communities. See
