Biogas: how it works

Here is a hint for how the Sanilac Green Squad can dispose of waste on Planet 4-H. Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Comprised primarily of methane and carbon dioxide, biogas originates from biogenic material and is a type of biofuel. It's a product of the anaerobic digestion or fermentation of biodegradable materials such as manure or sewage, and can be used in CHP plants.

Teen Designs Eco-Homes of the Future

4-H Green Squad Teens in Sanilac County are not so different from teens around the world. Meet Digital Open (digitalopen.org) winning teen Ferran Rovira Bosca, of Spain. This 15-year-old created a concept for an "Eco Self-Sustaining House" -- architecture of the future that captures its own renewable energy, and is independent of electrical power companies. Ferran believes that technology can help us come up with new ways of protecing the environment, and designing our homes in new, smarter ways is the area that captures his interest.

Building a hoophouse - part two - with Adam Montri

Michigan State University hoophouse specialist Adam Montri and his wife Dru put up their own passive solar greenhouse at their Ten Hens Farm in Michigan. Part 2 of this three-part series on Sustainable Farmer.com shows the Montris and their friends working on the polycarbonate endwalls and installing the two layers of polyethylene that cover the hoophouse. Dr. John Biernbaum of MSU's Student Organic Farm also offers tips.

Building a Hoophouse - Part One - with Adam Montri

Adam Montri is the hoophouse specialist for Michigan State University. Hoophouses (or high tunnels) are unheated greenhouses that are becoming increasingly popular with home gardeners and farmers eager to extend the growing season. Montri is also building his own hoophouse, and Sustainable Farmer.com asked him for tips, information and advice.
