You are intentionally missing the point. The pedantic definition of family is a strawman, in this case.

Sorry it came across that way. I was hoping to point out that there are shades of truth to what you say. Probably lower class people have a lot more latent trauma passed through generations.

Sure, I agree with that. Trauma can definitely be generational.

Also, the OP pretty much says they are not in Ukraine in a comment: > I think Probably the war will end because Russia and America are busy in Ukraine

Yeah I don’t think it’s common knowledge in the west that our governments are doing the color revolution dance in Sudan.

> Yeah I don’t think it’s common knowledge in the west that our governments are doing the color revolution dance in Sudan.

But Wagner (a Russian PMC) is arming the RSF which are the ones trying to overthrow the current government.

So I fail to see how your assertion holds any water.

> things that wouldn't fly in million years in my current home in Canada, were perfectly viable solutions in warzone. You’d be surprised! I’m near Ottawa and in the past year I’ve been without power for 8 days, 5 days, and a handful of other times. I’m on well water and our septic system requires a pump. When the power is out we have no water, sewer or heat. The cell tower nearby only has about 1-2 hours of reserve p…

It doesn't solve the "if no power, no internet" issue completely, but have you looked at getting Starlink? Seems perfect for your situation, assuming you have a generator or batteries. You can get the roaming version and not activate it if you already have good internet and then only activate it during a month in which you lose power.

Can you reactivate Starlink without other outside communication?

I mean, so what? If one of my ancestors fought in a war defending their/my country's freedom, I don't get to claim credit for what they did. I am privileged that those ancestors made the sacrifice they did and don't have to fight in a war myself.

I believe there’s more nuance here. If both of my grandfathers fought in WWII and neither of yours did, my parents are likely to have picked up a lot of latent trauma that yours did not. I believe the lower classes in this country are less “privileged” for their freedom , on average. Of course, the more time passes, the smaller this effect.

Interestingly, trauma and chronic stress gets passed through genes too.

Steel is bad as an electrical conductor as its much higher than copper internal resistance would waste a lot of power. I don't know if the military still use wired field telephones, but in case they do, the field phone wire is excellent. It won't sustain lots of current, but if you're OK with a few amps, then that cable is sturdy, water and oil resistant and it has both copper and steel core, the former working as go…

Around 2014 or so, we (light infantry) had field telephones on the books, but we only used them once for a field exercise to practice assuming all modern tech was down.

We used field phones all the time when I was in light infantry (82nd Airborne). Pretty much any time we were in a fixed position out would come the commo wire so as to not give our position away.

They even went as far as having us string wire out to our ambush sites when we were on the Iraqi border during the first gulf war and reel it back up when we came in. Zero radio signals out there because they didn’t want them to know that a whole division plus French armor was there.

Modern tech is good and all unless you have some dumb Joe that keeps erasing the codes out of the radio by turning on the truck without putting it on standby or something…never quite figured that one out.

Daily reminder that online, someone well-off lying in bed with a nice bowl of soup can be talking with someone homeless in a third-world country with no chance of improvement whatsoever. Hopefully the OP in SE is not the latter and it's just a temporary situation, especially if they're in Ukraine and Ukraine wins.

They could also be talking with a voluntary soldier who is fighting for an invading military. Lots of ifs and buts to consider.

It's not privilege, millions of people have died defending the right to not be invaded by an asshole neighbor. Don't forget the price people have paid. Some places seem to be less interested in that, because they want to invade their neighbor, and we should be aggressively hostile to that very concept, and anyone who espouses the belief.

Unless you or your family were the ones that fought, it is privilege. Privilege isn’t a “bad word,” either - it’s okay to have privilege. But acknowledging it’s existence goes a long way toward building humility and understanding the situation of others who don’t have it.

These debates over privilege get complicated because everyone is privileged on some facet of their existence.

Fly to Brazil, take a cab around Central Sao Paulo. Your understanding of the world is warped by the safety and availability of goods. It's incredible when you get in places where the state doesn't function at let's say 50% of what we get in the first world. It's one hell of a learning experience.

I was recently in northern Vietnam. You could spend an hour having a simple conversation via Google Translate. Made me realize there are still big chunks of the world where you can't take basic literacy for granted in 2023, even of people in their 30s.

Google Translate is really, really, really bad for Vietnamese, so they were probably having trouble understanding the mutilated Vietnamese it was spitting out, more than anything.

I assume you didn't mean to imply that "basic literacy" == "knowing English", but your post does somewhat come across that way.

Sure. And it’s not a competition. Acknowledging the ways in which we are privileged is all I’m suggesting we do.

Living in a warzone affords very little privilege, but likely not none.

> Can you connect them in series instead of parallel, giving you a high voltage and low current?

You can probably do this for a little while, but your total current through the circuit is limited to the photocurrent generated by the lowest performing cell. Otherwise you'd get a charge buildup.

(sorry, I don't have a quora account)

Not sure how you'd handle high voltage DC with most things though, it's only slightly better than using high voltage AC with a commercial inverter.

Generally the current ratings on those wires is given in terms of temperature rise over ambient. The current rating for a wire that is allowed to rise 60C is much more than one only allowed to rise 30C.

As it gets hotter the resistance goes up and the system becomes less efficient, but it's not usually a sharp break. It will get hot, so you'll need to keep an eye on it. That's not so bad to do manually, just be conservative.

If we're talking days, I think you should just use trial and error. Use the inverter to up the voltage, add loads slowly and keep an eye on the voltage on the load side (if it drops a lot you're drawing too much current) and keep an eye on the wire for hot spots (honestly wish I could suggest a way to do this without hazard of touching it, I don't know if you have a thermal camera).
