Engineering & Technology for a Sustainable World

Houses of Straw ... 7
When author David Bainbridge attended his first straw-bale-building workshop in 1989, he thought building with bales would take at least 20 years to catch on. "I never anticipated how quickly it would spread around the world," he says. "The advantages of straw bales are now well understood in the building trades. And where grain is grown, bales can be cost competitive with conventional construction."

The Compaction Problem ... 9
The "show me" state - a Missouri nickname made popular by native skeptic President Harry Truman – is the proving ground for a soil strength profile sensor. It shows measurements of soil strength at five depths in the soil profile, shows penetration resistance, and thereby enables generation of a soil strength map, which in turn shows compaction differences. Need convincing? Read on as Ken Sudduth shows off the Missouri-made SSPS.

Environmental Technology ... 11
Like a Cinderella story, the new Valley View plant is turning "necessary-expense" waste management into an attractive, moneymaking operation. The plant operates without treatment lagoons, eliminates the land application of nutrients, and captures greenhouse gases and converts them to clean-burning fuel, says Dave Townsend. For Crystal Peak and hog producers, it's a dream come true.

Teaching Safety ... 13
Agricultural safety is taught not caught. But Gary Roberson concentrates on upgrades that “catch on” in bio and ag engineering and technology programs reaching classroom as well as distance education students and more.
