Industrial Scale Renewable Energy:
A Skeptic’s Scrutiny From The Hinterlands
Mark Haynes
Mark’s talk will be an examination of and a skeptic’s perspective of many of the claims about renewable energy from the rural, environmental, power grid, and “big picture” perspectives.
Mark retired in 2021 as President of Concordia Power, a small consulting firm focused on strategic services in the areas of advanced fission and fusion energy development. Previously in his professional career, he was a Vice President of General Atomics and a Professional Staff Member of the United States Senate Committee on Environment and Public Works. He has a Master's degree in Environmental Science from Miami University in Ohio and a BS in Environmental Science from Morehead State University in Kentucky. Mark and his wife Caroline have a home in Arlington, but spend much of their time working on their forested land in West Virginia, where they have an off-grid solar cabin. As a volunteer, Mark is highly involved in energy development and land conservation issues.

No Blueprint for the Moon:
Navigating the Unknowns of Extraterrestrial Construction
Dr. Caitlin Ahrens
This presentation examines lunar architecture not as science fiction, but as an applied problem in risk management, engineering under uncertainty, and evidence-based design. We will explore what it would actually mean to plan and build structures on the Moon, where our geotechnical data are sparse, environmental hazards are extreme, and many Earth-based design assumptions simply do not hold. We will delve into strategies for site planning in an extreme, unfamiliar environment, where Earth-based assumptions must be rethought. Key challenges discussed include working with limited data, potential hazards from the environment, and the need for adaptable, resilient design solutions in lunar conditions.Dr. Caitlin Ahrens is an assistant research scientist at NASA Goddard Space Flight Center, and the University of Maryland. She is a member of the Diviner Science Team with the Lunar Reconnaissance Orbiter. In collaboration with Artemis, she serves as a technical support scientist to assist in risk assessments of astronaut, rover, and lander activity at the lunar surface. Dr. Ahrens is Principal Investigator on a recent lunar sustainability work funded by the (former) NASA Office of Technology, Policy and Strategy. She also is a member of the American Society of Civil Engineers (ASCE) working on how lunar architectures should be monitored for hazards, including construction, at the lunar surface.

"Everything you wanted to know about coronaviruses but were afraid to ask."
Laura H. Kahn MD, MPH, MPP, author of One Health and the Politics of COVID-19
Using an interdisciplinary One Health approach, Dr. Laura Kahn will draw upon material from her book, One Health and the Politics of Covid-19, to talk about the history, science, research, and politics of coronaviruses. One Health is the concept that human, animal, plant, environmental, and ecosystem health are linked. This is a relatively new term, but an ancient concept recognized by indigenous peoples around the world.
Coronaviruses are zoonotic viruses, meaning that they originate in non-human animals (i.e., bats) and spread to humans. The most well-known coronaviruses are Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and Covid-19. Unlike SARS and MERS, which emerged in 2002 and 2012, respectively, Covid-19 appears unusual in some of its clinical manifestations. The gold standard evidence used to prove the natural origins of the earlier coronavirus epidemics is lacking with Covid-19. The origin of this virus remains controversial.
Coronaviruses were first discovered by veterinarians in the early 1930s. Physicians discovered them in the 1960s while studying “the common cold” but assumed that they were merely nuisance microbes. Medical researchers lost interest in them until the shocking appearance of SARS. Gain-of-function research of pandemic potential pathogens, such as SARS, and the possibility that it might have led to Covid-19, raises concerns about the ethics and risks of this type of research.
Dr. Laura H. Kahn is a physician, policy researcher, educator, and author. For almost 20 years, she was a research scholar in the Program on Science and Global Security at Princeton's School of Public and International Affairs, Princeton University. Her education and training encompass nursing, medicine, public health, and public policy.
A native of California, Dr. Kahn holds a bachelor's degree in nursing from UC Los Angeles, a doctorate in medicine from the Mt. Sinai School of Medicine, a master's degree in public health from Columbia University and a master's degree in public policy from Princeton University. Dr. Kahn is a fellow of the American College of Physicians. In 2007, the New Jersey Chapter of the American College of Physicians awarded her with their highest honor, the Laureate Award. In 2014, the American Association of Public Health Physicians awarded her with a Presidential Award for Meritorious Service, and in 2016, the American Veterinary Epidemiology Society (AVES) awarded her with their highest honor for her work in One Health: the K.F. Meyer-James H. Steele Gold Head Cane Award.

Nate Pedersen on his book
Pseudoscience:
An Amusing History of Crackpot Ideas and Why We Love Them
Pseudoscience is a wild mix of history, pop culture, and good old-fashioned science–that not just entertains, but sheds a little light on why we all love to believe in things we know aren't true.
Nate Pedersen is an award-winning nonfiction writer and anthologist living in southern Minnesota. He is the co-author of Quackery: A Brief History of the Worst Ways to Cure Everything, Patient Zero: A Curious History of the World's Worst Diseases, and his most recent book Pseudoscience: An Amusing History of Crackpot Ideas and Why We Love Them, all from Workman / Hachette.
