Not just an EMP that needs to be worried about. A solar coronal mass ejection could cause similar effects. Apparently we are overdue one now. Getting spare parts at the best of times is difficult enough. I wonder if there has been enough thought given to storing spare parts within suitable EMP proof containers outside of the military in Western countries.

I think an North Korean EMP could be deterred by making a statement to the effect that an EMP that is non-negligible over any point of US sovereign territory would result in a specific megetonnage delivery of US nuclear weapons onto North Korean territory within a one hour timeframe. I think the man in charge of North Korea would get the message.

I have often thought about investing in compressed air equipment such as tools, motors and the like and the compressed air being stored and a large reservoir that is continually replenished by either a wind or hydro powered compressor.

I disagree, a solar coronal mass ejection is orders of magnitude less dangerous than a man made EMP.

An EMP induces damaging voltages in very short conductors such as those within any modern appliance or vehicles that contain electronics.
These voltages will kill almost all modern electronics unless specifically hardened or stored in protected facilities.

A solar flare or CME by contrast will have zero effect on small equipment such as vehicles or household equipment.
Dangerous voltages are induced only in very long conductors, miles long at least.

The main victims will be long high voltage grid lines and the equipment connected thereto. DC voltages induced in AC lines can kill transformers, as can simple over voltage.
Any other facilities that use metallic structures miles long are at risk, telephone and telegraph lines, railway lines, and long pipelines for example.
Even very long barbed wire fences could be a risk.

A serious event could interrupt grid service for hours at the absolute minimum, and possibly for YEARS depending on the scale of the damage.

Pipe lines carrying gas or oil could become dangerously hot with sparking or arcing at the ends with risk of fire.
Dangerous voltages and currents would be induced in long railway tracks, killing any electric signalling, and probably starting fires.
Very long wire fences could have enough voltage induced to kill persons or livestock or start fires.
Long distance copper telephone or telegraph routes would be at risk, but most are now fibre optic which is usually immune.

Google the "Carrington event" for details of a previous event, before the days of large electrical grids.
