At a Minnesota dairy, Holsteins are in the energy business: Renewed interest in manure/biogas digesters:  "Each Holstein on Dennis Haubenschild's dairy farm chomps down 90 pounds of feed, yields eight gallons of milk, and produces 220 pounds of manure (including the shredded newspaper bedding) - daily. It's a pretty standard operation in the dairy industry. But his 750 cows are also in another business with a different product line: Every one of the half-ton beasts generates 4 kilowatt hours of electricity a day... One drawback with cow-to-electricity systems, says Mr. Nelson, is that they operate efficiently only on farms with 400 or more cows. That's six or seven times the average size of a Minnesota dairy herd. "We'd like to see design and engineering that would make these systems feasible on smaller farms," he says."   7:51:41 PM  permalink
