Green-trust is a offgrid non-profit renewable energy and sustainability research center, specializing in green fuels such as biodiesel, ethanol, and biodigested methane.One of our Partners was Al Rutan, commonly known as "the Methane Man", and a long time researcher of Bio-methane and renewable energy. After he died, we dedicated ourselves to making sure his research stayed available. We converted his video tapes to digital, reproduced his articles, and added some spreadsheet forecast tools.
