I am interested in constructing a bunker, and trying to learn as much as possible. Very insightful thoughts and ideas in previous threads from Bunkerbob, North & Allen Idaho. Does anyone know what additional measures are necessary to shield against an EMP devise or CME solar flares? It will be important to protect electronics, batteries or communication devices. How does one protect a home solar system from a CME? These scenarios seem more likely in the near future than many other possible events or threats. Thanks, any type of information is appreciated.
