Mechanical engineering student Sam Walker and his solar trailer.
As a mechanical engineering student committed to energy efficiency, Sam Walker designed and built a solar trailer with two other OSU engineering students.

When Sam Walker wanted to build a solar trailer for his senior design project, his professors balked. Most projects were either industry sponsored or based on faculty research, not on the design whims of a student.

But Walker stuck with his vision to build a mobile station that could supply power using solar energy — and luckily so. After writing a formal proposal and raising thousands of dollars, his professors agreed to let him design, build, and present the trailer at the annual Engineering Expo. Continue reading

Home Biogas CooktopAs people increasingly seek sustainable energy solutions, they may come across the product offerings of a small startup company in Eugene, Ore., called HESTIA Home Biogas, makers of anaerobic digesters for home use. When they do, HESTIA wants to be ready with a biogas cooktop.

“They want to be able to run off just that raw biogas coming straight out of the digester,” said Lucas Stangel, a graduating senior in the School of Mechanical, Industrial, and Manufacturing Engineering. Continue reading

To the untrained eye, the Puralytics “lily pad” looks like nothing more than a flat piece of mesh, approximately one foot in diameter, passively floating Nano Lilypadon the water. But its appearance belies its power. So dubbed because of how it mimics the water plant by that name, a nanotech lily pad uses the sun to activate five photochemical processes that break down or remove organics, coliforms, and metals from storm water.

The emerging technology used to create the pads is patterned after Puralytics’ award-winning nanotechnology for drinking water purification. The process actually destroys contaminants, so it eliminates the problem of disposing of most toxic substances left over from traditional filtering methods. Continue reading

Sea salt productionEVOO, a cooking school in Cannon Beach, Ore., wants to produce gourmet sea salt from the Pacific Ocean, so they enlisted the help of three senior chemical engineering students — Austin Danielson, Cameron Oden, and Paul Robideau — to develop a sustainable technology to achieve their goal. Besides producing salt products that can be variously flavored, the team wants to create a potable water byproduct that can be used to irrigate a community garden and provide a water source for animals.

StereovisionWhen humans view the world with two healthy eyes, we see in stereovision, which gives us depth perception and allows us to avoid running into the things around us. Scientists have long since implemented stereovision in computer systems for various applications, but until recently it wasn’t practical to implement such a system in real time because of the large amount of computational power it required.
