A couple of years ago someone stole my home's copper downspout.

And just about every power pole's grounding wire is long gone in this area.
Sounds like it is time for a few security cameras, which have come way down in cost these days if you do your own installation.

Recovering copper from discarded equipment collides with the amounts they want to profit, otherwise won't move a finger...

The fact that electricity somehow became the savior of mankind really baffles the heck out of me.
The fact that computers somehow became the savior of mankind really baffles the heck out of me.

The fact that smart phones somehow became the enhancer of mankind laziness baffles the heck out of me.

The fact that artificial intelligence somehow will become the diarrhea of mankind really baffles the heck out of me.

Ha ha, thanks for the laugh with that last one, even though it is true! :)

Money makes the world go around; politics makes it stop.

Last week I was in my local Lowes (Home Improvement Store. The copper wire is no longer just out in the aisle. Now it's protected by bars under lock & key. The same is true of Home Depot stores. Glad years ago I had a good stock of AWG 12/3 and AWG 10/4 because those 250 foot rolls aren't cheap today. I have seen houses stripped of not just copper wire literally ripped from walls but copper plumbing as well.

There is a cure for copper theft, keep it energized.

Hi Ron,

Oh wow, I have not looked for wire in Home Depot in a long time now maybe I'll check that out in our local store. I've been getting lumber for various woodworking projects.

When I was quite young, we had a neighbor who would gather copper wire and burn the insulation off in a 50 gallon steel barrel. Smelled up the whole neighborhood.
I knew another guy that went with a friend and stole copper wire from near the train tracks, not sure what it was for but there was a LOT of it there, but they got caught one night :)

Copper plumbing must be a godsend for those guys. One piece is fairly heavy. I used two long pieces for an antenna one time long ago. I already had it though for actual plumbing repairs. The 1/2 inch size makes a really good antenna and does not suffer as much from skin effect as a copper rod would.

Wow, we had the same neighbor. :) Really my friends grandfather was burning off wire insulation.

Thinking back many churches had copper downspouts for the gutters. Even churches are fair game for stealing copper apparently.

Wow, I feel really sorry for those with copper tile roof shingles :)
No wonder we do not see them around much anymore (ha ha).

It must have been a really good idea to use copper for roof shingles back then, until they started to disappear. It might turn green, but I bet it would last a long time if they would stay put.

The big challenge with the mandated electric vehicles will be the power to recharge them. HOW will it get thru the legacy grid to all those charging stations delivering all of those ten minute charges at once??? How doe you deliver 120 kilowatt hours in ten minutes at each of ten charging stations?? With a charging station only having one 1000 amp 480/3 phase power drop? THAT is the part that I can't figure out.
Perhaps an atomic battery will be the answer. Just a "small" atomic battery device for every charging station. ( I am just being nasty with that.)

Hi,

I've been asking that question for as long as EV's have been around (almost).
The 'said' solution is to upgrade the local infrastructure, but that's not enough. It has to be an upgrade for the entire grid. Not only that, will there be enough energy available even after that is done.
I do not see anyone jumping to upgrade the grid either.

Take California for example. They already have big problems supplying energy to all the homes and businesses. I could imagine what the situation would be if everyone had an EV and no gas engine cars.

Maybe some people think that electricity comes from out of nowhere.

If only it was possible to make small cars without 700 horsepower motors capable of driving through cinderblock walls. Or, crazy thought, locate housing closer to work/school/shopping so people don't have to drive everywhere.

If they would sell in large numbers it would have a large market share. People don't want them for various reasons, like making older people feel even older.

Larger cars that you can step right in and most importantly, get out from are a driving necessity detail that I think most modern, young designers give little attention to.

Companies have tried and failed over generations of auto production.
