Is Carbon Capture Realistic?
Chemical and Petroleum Engineering Department,
University of Pittsburgh
Join University of Pittsburgh professor Chris Wilmer for a discussion of the future of carbon capture technology. This very active area of engineering research explores the development of technologies that can be retrofitted onto fossil fuel-based power plants to reduce greenhouse gas emissions into the atmosphere. Retrofitting thousands of coal power plants across the globe would be a massive undertaking, and researchers need to know how feasible such a project would be.
In his talk, Wilmer will consider this problem from the molecular scale and ask what the most efficient carbon capture membrane would look like, whether it can realistically help mitigate global warming, and how it compares to existing technologies.
Wilmer is an assistant professor in the Chemical and Petroleum Engineering Department at the University of Pittsburgh. His research focuses on the use of large-scale molecular simulations to help find promising materials for energy and environmental applications.

Light Up the Sky with Stars
Lecturer, Author, & Astronomer
How far do you have to travel to see the stars clearly? Join lecturer, author, and astronomer Diane Turnshek as she discusses how light pollution not only prevents us from living under a sky bright with stars, but also negatively impacts human health and the environment. Turnshek will examine how innovative science and technology can reverse this steady creep of sky glow, allowing us to view the same star-filled sky that all past generations did.
Diane Turnshek is a lecturer in the Department of Physics at Carnegie Mellon University and the Department of Physics and Astronomy at the University of Pittsburgh. She has published hard science fiction with a focus on space colonization and first contact. Her love of both astronomy and science fiction led her to crew the Mars Desert Research Station near Bryce Canyon, Utah in 2012, where she turned her attention to dark sky advocacy. Her fight against light pollution has taken many forms, including giving a TEDxPittsburgh talk. Turnshek is also a 2015 Dark Sky Defender award recipient, recognized by the International Dark-Sky Association for her contribution to light pollution mitigation.
