Ride the wave: soliton resonance may enable mechanical energy harvesting

Energy harvesting – creating electrical energy from cars driving over a road, or people walking on a bridge – has long been theorized as a potential source of sustainable electricity. But due to the physical properties of those vibrations, implementing the process has been largely infeasible. Now, Andres Arrieta has proposed using metamaterials as physical frequency converters, potentially bringing us a step closer to harvesting the energy of those vibrations.

The clapping circle "squeak," finally explained

This brick circle on Purdue's campus is called the "clapping circle"... when you stand in the middle of it and clap, you hear an odd squeak. Thanks to the research of professor Stuart Bolton and his acoustics students, now we know why.

Radiative cooling paint

What if paint could cool off a building enough to not need air conditioning? Xiulin Ruan has pioneered radiative cooling paint; instead of absorbing sunlight, it radiates the heat back into space. This actually cools surfaces below ambient temperature, something paint has never done before.

Don Giffels remembers the early days of Herrick Labs

Today, Herrick Labs is the foremost academic HVAC lab in the world. But when it opened in 1958, its focus was on how livestock reacted to refrigeration! Don Giffels (MSME 1959) was one of the first graduate students at Herrick, and shares his reflections.
