Sometimes the smallest things can make big differences. The sway of a bridge or building caused by wind is barely perceptible for most people, for instance, but Ryan Harne sees a major potential source of energy in what few others even notice. An assistant professor in Ohio State’s department of mechanical and aerospace engineering, Harne has studied vibration-energy harvesting for several years. His research examines how the movements of large structures, like skyscrapers and bridges, could translate into usable energy. “If a bridge weakens steadily over time due to swaying, nowadays it’s quite common to go ahead and either retrofit
Throughout the state of Iowa, something interesting has been happening with farms over the past few years — they’re disappearing in the hundreds. According to the U.S. Department of Agriculture, the number of farms fell by 500 in 2014 to a total of 88,000.

Miscanthus is a tall-standing perennial grass that’s grown in stature — both literally and figuratively — on Iowa’s campus.
Students at Big Ten universities aren’t waiting until they get out into the “real world” to make a difference. Find out how they’re working together to create positive, meaningful change in this BTN LiveBIG series: the Student Section. Imagine you rip open the envelopes of all your monthly energy bills — gas, HVAC, hot water and electricity — and they all say “Amount Due: $0.” Sounds impossible? It could be a reality soon, thanks to recent energy-efficiency advances in home construction. And a group of several bright young engineering, architecture and design students at the University of Minnesota is leading the
