  • Mexico & Agaves: Moving from Tequila to Ethanol - With a history that stretches well back into pre-Columbian times, certain varieties of the Agave family are beginning to capture the attention of investors and researchers interested in indigenous plants and trees in countries around the world that are not used to produce food and have attributes that make them prospective sources of ethanol. (Renewable Energy World; August 7, 2008)
  • Ethanol from Garbage and Old Tires - Tubes packed with bundles of white fibers are the core of a bioreactor, which is the heart of a new technology that Coskata claims combine thermochemical and biological approaches to make ethanol out of wood chips, household garbage, grass, and old tires--indeed, just about any organic material. (MIT Technology Review; March/April 2008)
  • Methanol -- Ethanol's Sister Product - Ethanol can be an even more effective energy alternative to petroleum if the unused portion of the crop are used to create methanol. (PESWiki; Feb. 26, 2006)
  • Tectane: H20 Injector and Aquahol - H2O Injector is an inexpensive add-on device for car engines which reduces emissions and increases mileage up to 40%, and can allow cars to run on 75-octane gasoline or ethanol fuels. Aquahol is the separate injection of 80% ethanol and 20% water, which is the cleanest-burning fuel. Drawbacks?
  • Switchgrass shows promise for ethanol production - A large-scale trial of switchgrass suggests that prairie grasses grown using only moderate amounts of fertilizer on marginal land can produce significant amounts of ethanol, making the crop a more viable plant source of biofuel than previously thought. (PhysOrg; Jan. 7, 2008) (CBS News) (Slashdot)
  • Cannabis Hemp as a Global Warming Solution - Proponents argue that easily grown and robust Cannabis Hemp is one of the best if not the very best plants overall for fuel, building supplies, medicine, fiber, food, paper, and substitute for wood. Some go so far as to argue that it could be the best solution to global warming.
  • Biofuel nanotech process intensification - NanoDynamics' ND Fusion rotating tube reactor provides for faster, higher, more efficient ethanol yields by boosting fermentation without damaging fragile yeast cells and generates higher purity ethanol with lower energy and capital cost. It has the ability to economically convert sugarcane process streams to ethanol. (Biopact; Feb. 27, 2007)
  • Zeolite Membrane for Ethanol Dehydration - Mitsui Engineering will use a zeolite membrane in dehydration systems for bioethanol plants, to remove water from the ethanol produced. Only water passes through the membrane, thereby helping to reduce process fuel consumption by around 10% compared to other methods. (Green Car Congress; Jul. 11, 2007)
