Electric Fields, Son.
Dave Jones and Chris Gammell discuss a Veritasium video explaining that electromagnetic energy flows outside wires in the fields, analyzing the transient response of a circuit with half-light-second wires using capacitance and transmission line theory. They then review a Wendover Productions video on grid infrastructure, discussing high-voltage DC transmission, pumped hydro storage, and smart EV charging. Finally, Gammell announces he has joined a startup founded by Jonathan Berry to build an IoT platform using Zephyr RTOS, while Jones discusses the scaling of Linus Tech Tips and career dynamics for older hardware engineers.
