Robot dog with a machine gun
Hmm…wondering if attacking with a pile of rare earth magnets would be effective.
Where Two Bullets Killed Millions
Rare Earth is one of the best series on YouTube right now and it gets criminally-little notice.

How To Crack An Electronic Safe With A Magnet And A Sock
To be fair, that is a Hugh Jass rare-earth (neodymium) magnet, that costs $40 more than the safe (quick search example- $173 vs. safe $134), and not likely that a casual thief would have it on hand. Good for a locksmith to invest in though.
I would like to see them test progressively smaller magnets, to see what the smallest is that would still do the trick.
Elon Musk introduces the TESLA ENERGY POWERWALL
I have solar now, so I'll answer.
Today, if you want battery power at home for storage of solar, wind, even micro hydro generated power, you have one real choice....lead acid batteries.
Pros (compared to lead acid)-At best, lead acids are large, unsightly, need an enclosure, need a charger, have a 1000 cycle life span, need maintenance, can't be frozen or allowed to get too hot, use acid, are expensive to dispose of, and are more expensive than this (better?) technology by almost a factor of 4. I recently replaced my battery bank of just over 1KWH for around $1200-$1400, while he's advertising 10KWH for $3500!
Cons-likely lots of 'rare earth minerals' needed, which cause massive pollution where they're refined (China), unknown rate of failure/fire, other unknown problems, and anti-renewable energy people's heads exploding trying to come up with new reasons that renewable energy sucks.
So how does this differ for home use to whats available now? pros and cons...anyone?
Power Japan Plus - Dual Carbon Battery
Tell an engineer that you want a battery that’s powerful, safe, reliable, and cheap, and he’ll probably respond, “Powerful, safe, reliable, cheap: pick any two.”
It's "dual carbon" because both anode and diode are carbon. It is still a lithium ion battery, but it is much cheaper because most lithium ion batteries today use rare earth metals that are hard to mine, very expensive and difficult to recycle/dispose of.
So this battery might be cheaper and safer, but jury's still out on powerful and reliable.
But didn't the video say the 'electrolyte' was still made of lithium ions? Maybe I missed something?
I want it to be a real, cheap, stable, eco-friendly, powerful battery, but I have to wait to see it for sale and in action first.

World's First Electric Generator
After I saw this, I bought some rare earth magnets online and went down to home depot and picked up a simple copper pipe and have the same little fun experiment. Want I want to do is to get a circular track, and it with a ball magnet inside and let it slowly roll around and generate a bunch of heat just by the magnet falling.
Nine great uses for magnets in the home and shop.
Magnet Pro Tip #134
If you leave the house and forget to bring those notes that are on the fridge back home, just swallow a handful of very strong rare earth magnets and stick the notes to your abdomen with other magnets! Haha, you'll never forget those "must remember notes" again.
But wait! Feel like you need to have your kid's fingerpaintings handy, use more magnets to stick those to you as well! The possibilitie are endless!

Remember when magnets were simply used to hold shit to the front of the fridge????
Ahh...the good old days.
The Umbrella Man
@spoco
the "official" government theory on what happened is also a conspiracy theory.
and there are always political underpinnings on where blame is placed, and how.
I mean, it's a wonderful theory that a guy in the remote stretches of Afghanistan trained and coordinated a bunch of Saudis conducting an URBAN airport operation. he must have had terrific cel service at the batcave.
it's a dumb theory, but still a theory.
and i'm quite sure invading Afghanistan had nothing to do with the largest amount of untapped rare earth minerals anywhere in the world. what a lucky coincidence!
and given that a modern empire needs to have 2 essential things to maintain it's empire - energy and technology, there is absolutely NO WAY we are in Afghanistan for anything but killing that dude, women's rights, feeding the orphans, and keeping us snuggly safe and secure.

rare earth.
I knew they has some sort of exploitable resource,but didn't know what. Usually its Oil,but that is nearly as good: some neccessity for keeping industry going and profits up.If America wants to be the New Rome and spread Pax Americana across the world,then they should follow the Roman idea through and kick back some of those spoils of war back to the homeland where all the cannon fodder comes from. Who will buy all this crap we import from China if noone has jobs? Greed will be their downfall,that and an embaressing short sightedness that hopefully won't doom the rest of us along with them.

Here's my translation of "environmental protection":
"Piss off, America! We're not some third world country that you can bully into handing over all its resources for a pittance."
What, but they even got Canada to do that ⇩... The bully wants what he wants
