I've been thinking (my DW and kids would suggest that now is a good time to run for cover).

With the potential for EMP damage Impending solar storms , and based upon the effects of EMP, that is known Carringtton Event & Starfish Prime , would the following idea have merit. I am not and don't play one on TV – an Electrical Engineer.

Would my metal sided outbuilding function as a Faraday Cage? It has sheet steel sides and roof. Would I need to bond the roof and sides, the doors (walkthru and vehicle) to the building. Would the rebar and rewire in the floor be enough, would I need to bond this to the walls. What size bonding conductors and how many would be needed? Realistically what current flux would I need to consider in the calculations?

Thoughts? Shared knowledge. As the kids say: “skool me”

Thanks
