George has been an Amateur Radio operator since 2013 when he passed the Technician Exam at the 2013 Dayton Hamvention. In 2016, he successfully tested for Extra. His interests include software-defined radio, digital modes, and fixing analog audio gear.
He graduated from the University of Missouri-Rolla (now MST) with a Bachelor’s in Electrical Engineering and has been asking the right questions, breaking stuff, and causing trouble since 1984. He has done work for Monsanto, Pfizer, Aventis Pharma, the Immigration and Naturalization Service, Baxter Healthcare, Amtrak, and Sachs Electric.
Currently, George works at Enterprise Rent-A-Car as a Senior Software Engineer. He works in the Rental Billing department and is responsible for systems that send rental invoices worldwide.
George’s presentation will offer a clear, technical view of today’s battery technologies—how they work, why they fail, and what actually matters beneath the marketing gloss. We’ll walk through chemistries, performance trade-offs, safety considerations, and real-world behavior that make battery science far more interesting than its reputation suggests. Expect a technical discussion, a few gentle myth‑deflations, and just enough humor to keep the electrons moving.
The meeting is on July 24th @ 7PM. General meeting info and location can be found at the following link: https://slsrc.org/general-meeting-info/
