Don your foil hats, and I'll tell you a tale of what my Bride and I did to mitigate CME/EMP ruining our costly electronics.
In the past six months, we installed a PV solar system, and are at this moment on the cusp of getting our wind genny operational -- I'll do a thread
on this once the wind genny is up and running.
So, in the process, there are delicate electronics involved -- charge controllers, inverters, etc. First, there are lightning/surge supressors on
both the DC and AC sides, but how to mitigate CME or an EMP? Remember, here on our sleepy little island, I can't just stroll down and buy
replacement equipment, even if I could afford it.
I had built exterior weatherproof lockers. They are substantial, and went through Hurricane Paloma without gaining a single drop of visible
moisture inside. To comply with NFPA guidelines and regs, I lined the interior of the wooden lockers with hardee board -- which is rated as
"nonflammable". Just before I put down the hardee board, I lined all locker spaces with peel n' seal -- an aluminum-backed rubber. I made
sure that the aluminum was contiguous, especially in the corners, and I lined the interior of the doors to the lockers such that they made positive
contact with the interior aluminum when the doors are closed, which is most of the time.
I can't be postive, without testing that I don't have equipment for doing so, but I believe I've created one 4'X2'X2' and one 4' X 4' X 2'
faraday box. We'll see. I hope to never see a situation that tests it out, but it seemed a good thing to do -- only an additional three hours
plus $70.00 materials -- for a little peace of mind. Of course, an oversized ground is attached. Even for a foilhead like me this was a
Now what can our communities do? They can protect the delicate circuitry of switching stations, transfers, relays, etc. Many of these areas are
metal boxes anyway, requiring possibly only to complete the seal in pentrations into the boxes.
On a larger scale? I think it's a serious threat, but is it a credible enough threat, is the probability such that major urban areas might even
take notice, especially in these belt-tightening times? I don't know. I'd guess that most governments will choose to utilize that time-honored
method of protection of their electronics: Hope for the best.
