We've had a wave of copper thefts in my area. A month ago it was a couple, and
yesterday two women. I doubt they were stealing wire for EVs. Anyway, a fellow
EVer just had the copper wiring stolen off his battery pack! It was a truck with
the batteries exposed in the bed.

Yeah, they definitely steal it to get the scrap price. It's a big problem
everywhere. Luckily some copper thieves are dumb enough to try to remove
copper from high voltage lines. This usually works to stop them from
continuing to steal copper. I have a vehicle that runs on 330v. That would
wake up a copper thief. But, I wonder what can be done to prevent or
discourage this theft? Maybe not much since ICE cars are stolen all of the
time and sent to chop shops.

I am using several intrusion alarm systems in my EV. The Link-10 E-meter
has a low battery alarm circuit that is connected to pin# 7 that can
operated any alarm system. It can even send the alarm signal by the RS-252
to a remote unit. If I forget to turn it off and remove a battery link, it
will make me jump back 10 feet

Then I have a commercial intrusion alarm system made by the same companies
that makes them for buildings. I have this system activating a siren or car
horn or pulsating bright lights and can also send to a remote unit.

Next, I built a 42 control switch on the console which includes all the
control switches plus backup switches to operated any circuit in the EV. Mix
in with these switches are the alarm switches. There is a certain sequence
of operation or the alarm will go off. This system is like a cypher alarm
system which I have built for high security areas.

Also you cannot open the hood and cut the battery cables because 12 volt
accessory circuits are double up. In this type of system, there are control
wires in the same jacket of the power wires. If you cut the wire, the alarm
will go off.

One time I was house setting for some people and this was the first time the
EV was setting outside. All the vehicles that was park on the street was
broken into, except mine. When you look in the passenger compartment there
are may blinking LED's going off and see a sensor unit that looks like a
eyeball looking at you, which scare them away. Some day, I am going to put
in a car video camera that can turn 360 degrees which can keep a eye on any
moving object or person.

There are many options for these types of alarms system. One that I do not
have hook up yet, is a transducer alarm unit, where if a person just touches
the vehicle, a voice will come up with any record message you want. If the
person is still touching or doing something funny, then it will bring up
more alarms systems.

<<<< There was a guy that had one of those where I worked once. It was also
a very crowded parking lot, so just walking to your car, it was likely
that you would touch other cars.
His car would tell you to move away from the car every time you touched it.
It wasn't long before people got in the habit of giving his car a quick
kick to set off the alarm every time it told them to back away from it. >>>>

Would have been better to have a calm female voice say "security
cameras activated".



Think more
Talk less
Become wise

Most of the trolley museums I know of, leave their overhead wire energized
24x7.

During World War II, copper was so scarce that when the Manhattan Project
needed to wire some cyclotrons, they had no recourse to but to obtain SILVER
from the Treasury. Since the Treasury doesn't speak 'tons', they ordered
428,750,000 troy ounces.

BART uses 3rd rail for power, but ground return is via the steel running
rails. The original system used "112 pound per yard" medium freight rail,
far more than adequate for their featherweight cars - however it required
ground feeders to carry ground current. On their extensions, they switched
to 140 pound, the heaviest freight rail made. ONE GUESS why!

I wrote a program to compare the resistivity, density and cost of several
metals, finalizing on cost per resistance.

It looks like in the current markets, a cable with a certain resistance
costs $10 in copper, $1.37 in aluminum and $1.97 in iron. Aluminum is 7
times cheaper.
