Building a better treadle pump—one step at a time

The first thing Jeff Evans, a recent graduate in entrepreneurship, did when he started his senior project was to locate Malawi on a map.

He and engineering students Travis Meyer, Kyle Kraemer, and Dan Good have since learned a lot about this African country, third poorest in the world, and developed a treadle pump they hope will make a positive difference for people there. They traveled to Malawi in March to test their product. Working with Peter Wyeth, associate scientist in International Programs, Trent Bunderson, associate director of International Programs, and faculty advisors Denny Davis and Jerman Rose, the team was part of a unique … » More …

Leveling the playing field

In softball, success or failure happens when the ball meets the bat. The faster a batted ball travels, the greater the likelihood of a batter’s success. Softball bat manufacturers are using technology to create bats that hit the ball harder than ever-but not everyone is pleased with the results.

Recent advances in softball bat performance raised concerns with the Amateur Softball Association (ASA) that softball bats generating high batted ball speeds were giving individuals an unfair advantage in competition and creating safety problems, says Lloyd Smith, an associate professor in the School of Mechanical and Materials Engineering at Washington State University.

Since 2000, the ASA, … » More …

Bose and Asay are named to National Academy of Engineering

Anjan Bose and James R. Asay have been named members of the National Academy of Engineering (NAE), the most prestigious honor in the engineering field. Bose is dean of the College of Engineering and Architecture at Washington State University and distinguished professor in power engineering. Asay is research professor and associate director of WSU’s  Institute for Shock Physics.

Election to the NAE comes from peers within the academy, based on nominees’ outstanding contributions to their field. Founded in 1964, the NAE serves with the National Academy of Sciences as an advisory board for the federal government through the National Research Council. Out of approximately 10 … » More …

Tiny Motors

The Palouse Piezoelectric Power (P3) engine is three millimeters wide, three millimeters long, and 100 microns thick, making it the world’s smallest engine. Just over 6,447 engines placed side by side would cover a page of this magazine, and each engine would be no thicker than the page on which it rested. The Washington State University researchers who created it believe the P3 has the potential to one day replace the batteries that power electric devices.

To operate, the P3 needs only an external heat source, such as   a burning fuel, the sun, a wood stove, waste heat from electronics, or even body heat. The … » More …

Solid footing

Ah, for the safety and comfort of computer modeling in a cozy office.

Instead, Thanos Papanicolaou, assistant professor in the Department of Civil and Environmental Engineering at Washington State University, found himself in a small boat in the churning waters of the Tacoma Narrows during a “peak tidal event” taking water velocity measurements, soundings, and underwater pictures of the bottom of the channel.

“I was a little nervous,” he admits, recalling his guide’s efforts to avoid vortices in the current.

Papanicolaou and graduate student Kyle Strom have been working to determine exactly how much of a scour hole tides make around the pilings that hold … » More …

Spray-cooling

Military adopts ISR technology in aircraft, ground vehicles

For reliability, advanced electronics need to be maintained at a stable temperature. This isn’t always possible in extreme military conditions. Isothermal Systems Research (ISR) has found one solution that’s winning awards and military contracts: spray-cooling.

Mechanical engineer Don Tilton developed the technology for a self-enclosed spray-cooling chassis about the size of a small microwave oven. A chemical liquid inside is sprayed onto electronics, dissipating heat on circuit boards and processors through evaporation, keeping the electronics at a stable, uniform temperature. In June 2003, the Defense Department gave ISR a Value Engineering Achievement Award in Washington, … » More …
