photographs of plants at various times of the year, as well as a number of other topics and re-
sources listed in appendix 1 and 2. You should also consider stockpiling guns and ammunition
(see chapter 10 ) for self-defense and hunting purposes. Even if you do not have any desire (or
training) to ever use a rifle or handgun, in the least you may use them for trade and barter, as
well as lend them to others in your survival network (or extended family), who may be better
trained and qualified to use them for communal protection and for hunting game.
Protection of Electronic Devices from EMP and Solar Storms
A detailed discussion of the technological strategies for protecting electronic devices from
EMP and solar super storms is beyond the scope of this topic, but I will give you a few general
guidelines. Detailed technical instructions are offered in the Department of the Army Technical
Manual TM 5-690, “ Grounding and Bonding in Command, Control, Communications, Com-
puter, Intelligence, Surveillance, and Reconnaissance (C4ISR) Facilities ,” which may be
downloaded for free on the Internet (see bibliography for details).
• Severe solar storms are likely to be devastating to the grid, and subsequently life and
society in general, but not harmful to your personal electronics, computers, automo-
biles, etc., provided you have adequate surge protection on your lines.
• EMP-simulation tests indicated that most electronic devices that are self-contained
and not operating at the time, wired to an antenna, or connected to significant lengths
of wires will be unharmed by EMPs or solar storms. Complex digital microelectron-
ics, such as personal computers, are quite sensitive to EMPs.
• Significant lengths of wires, such as network cables, grid connections, telephone
lines, and possibly even local wires that connect your renewable-energy-system com-
ponents to each other, may experience induced currents of high voltage and high am-
perage that are potentially damaging to solid-state circuits and microelectronics.
• Wires entering the building should be lightning protected with suitable ground-path
circuits.
• You can protect sensitive electronics (anything with integrated circuits, logic boards,
and microelectronics) with homemade “Faraday cages.” A Faraday cage is simply a
continuous metal enclosure that surrounds a device. Do not pierce your Faraday cage
with any power cords or antennas, or those items will bring induced currents into
your device, potentially ruining it. Your Faraday cage must be insulated from elec-
trical contact with the device it is meant to protect. Any fully enclosed metal box will
act as a Faraday cage, or you can make a simple Faraday cage by first insulating your
