Flushing the toilet stirred up a good idea in four young women from Walla Walla High School. They recognized that families use hundreds of gallons of water per day, a real problem in places faced with water shortages. To ease that, Karen Maldonado, Edlyn Carvajal, Sandra Escobedo de la Cruz, and Ruth Garcia developed a trapping system using an inexpensive charcoal filter to recycle wastewater back to the toilet tank.
The Walla Walla teens took their plan to the Alaska Airlines Imagine Tomorrow competition, an annual problem-solving challenge at Washington State University that encourages high school students to propose and present ideas … » More …
Traveling to the stars is one thing. Living there is another.
Washington State University is tackling challenges that could enable future astronauts to survive indefinitely on Mars and other extraterrestrial locations.
At the Voiland College of Engineering and Architecture, for example, a team of students designed a domed habitat that could be built robotically from Martian or Lunar soil with a special 3D printer. Dubbed the WazzuDOME, it was selected by NASA as a finalist in a design competition last year and earned the team a trip to the world’s largest science fair, the annual Maker Faire, in New York City.

Rahul Panat, an engineering professor at Washington State University’s Voiland College, and his colleagues Professor Indranath Dutta and graduate student Yeasir Arafat, recently demonstrated a significant advance in flexible electronics by showing that the metal indium, deposited as a thin film on a polymer substrate, can be stretched to twice its length without breaking—“a quantum improvement,” Panat says, over current methods.

A new touchstone for virtual reality
On its own, the gleaming silver skeletal hand looks like a disembodied limb from The Terminator. Strap it on a human and it becomes a glove to grasp things within virtual, computer-generated worlds.
Hakan Gurocak, the mechanical engineering professor at Washington State University Vancouver who designed the glove with his former graduate student Randy Bullion, says the haptic interface can be used in conjunction with virtual reality headsets and position sensors to add a new sense of touch to the experience of being in a digital environment.

Being put to the test at the ground zero of climate change
There’s the day the polar bear mangled the meteorological instruments. Or when a massive storm smashed two humidity sensors. Days of howling winds, extremely limited visibility, and weather so cold that power cords snapped like twigs.
For Von P. Walden, a professor in Washington State University’s Department of Civil and Environmental Engineering, the most exciting day as part of the Norwegian Young Sea ICE Cruise (N-ICE2015) team was last May when the thin layer of Arctic sea ice on which the researchers were working started breaking up.

Keeping a watchful eye in remote environments with aerial drones
Stealing through the shadowed plantation, an orangutan stops to feed on the tender shoots of a palm sapling. An instant later, she crumples from a rifle shot, her baby crying out in fear. The infant is eventually rescued and spirited away to a rehabilitation center for release back into the wild.
“At one time there were 2,500 of these orphans in Borneo,” says Chuck Pezeshki, a professor of mechanical and materials engineering at Washington State University. “It’s an enormous tragedy and the apes are now on the endangered list.”
Pezeshki says the native rainforest … » More …
Wearable electronics are leaving the lab and hitting the runway
From smart phones to FitBits, mobile electronics have been woven into the very fabric of our lives. But things are about to get a lot more literal as e-devices begin to be incorporated into the clothing we wear.
Imagine a “smart” shirt or other item of clothing that can monitor your biometrics and ping your doctor when something is out of the ordinary. Or, to manage diabetes, we’ll use a contact lens or pair of glasses to monitor blood glucose levels—and leave behind forever the expensive and annoying finger prick test kit. But wearable … » More …
Early science fiction authors tossed around the idea of mining the asteroids near Earth decades ago. Asimov, Heinlein, Pournelle, and other sci-fi luminaries wrote the concept into their stories of robots and space-bound pioneers since the 1940s. As with many of those authors’ ideas, we’re on the edge of fiction becoming reality.
Companies such as Redmond-based Planetary Resources plan to send robot harvesters up to the asteroids, likely within a decade, to extract water and rare minerals. CEO Chris Lewicki told me they are already in the prospecting phase, sending satellites to probe for likely mining candidates. The conference room where we met has … » More …
A jar of foul-smelling clay sits on the cluttered workbench. “I’d better not open it,” says environmental engineer Richard Watts. He grabs a smaller jar filled with liquid the color of a dirty mud puddle. “These are soil and groundwater samples from an industrial waste site in North Carolina.”
The repugnant samples arrived in comparatively pristine Pullman to be analyzed by Watts, who then advises the best ways to remedy the mess. In a twist, one of those methods involves the use of sugar.
Watts, a pioneer in oxidizing systems for the detoxification of polluted soil and groundwater and a professor of civil and environmental … » More …
