EAU CLAIRE — Dr. Kim Pierson, professor of physics at the University of Wisconsin-Eau Claire, will discuss a new, more efficient hybrid braking system at 7 p.m. March 8 in the conference room of Tower Hall on the university's upper campus.

Pierson will present "Harvesting electrical energy — a new braking system" as a part of Trash Talks, a lecture hosted by Housing and Residence Life's office of sustainability. Pierson will educate students, staff and the public about sustainability issues, emphasizing regenerative braking technology and research into a more efficient system.

"Regenerative breaking systems use an electric generator to slow the vehicle and store the electrical energy in a battery so that it can be reused," Pierson said. "A patent was just issued to a company to use a new electrical energy storage system called a super capacitor. The company claims the small SUV they are using could get 150 mpg."

Pierson, who holds a doctorate in physics from the University of Delaware, has been teaching physics at UW-Eau Claire since 1992. His current research includes renewable energy projects involving harvesting electrical energy from low-voltage sources, and projects interfacing sensors with computers to reduce energy consumption in buildings.

The Trash Talks lecture is free and open to the public.

Housing and Residence Life hosts Trash Talks lectures on sustainability issues from 7-8 p.m. the second Thursday of each month. The last Trash Talks presentation for the spring semester will be April 12. It will feature Dr. Matt Myer of the philosophy and religious studies faculty, who will discuss the ethics of using bottled versus tap water.
