( 3D Printing of Polymer-Bonded Rare-Earth Magnets With a Variable Magnetic Compound Fraction for a Predefined Stray Field | Scientific Reports )

( Just a moment... )

Like I said. Still in its infancy. Not inspiring at all.

The immediate problem is the batteries. Not the magnets.

When someone develops a more powerful battery that's a quarter the size of current batteries. Maybe then the tree huggers will have a valid argument.

Until then EV's are simply a fad. Nothing more.

Even then, actually charging them in a safe and timely manner remains a silent frontier of technical stagnation.
 
If the European Union aren't mining the materials themselves, then their getting them from somewhere else! How do you thing the US was able to obtain Titanium for the SR-71, when the US didn't produce it, and the Soviets were the only source to the metal…

Not by printing...
The YF 12 A program predates 3D printing by a significant span of time

Finally you understand what everyone was saying. You have to have those elements to use them. We are not able to create them. NOW think it through...these are RARE earth elements... Think...how many vehicles just in the US...how many batteries using the RARE earth elements?? Millions of tons of the hard to find stuff. If we could mine the asteroid belt...no boost from there... we may find some of these elements. We aren't even able to really get to the moon with equipment to look for them. Now...think about it...gold is fairly rare on earth...the elements we need in really large quantities are more rare than gold. We'll figure out plenty of ways to use the elements... if we can find them

They've been saying that since after Apollo 17 in 1972, and 50 years later we're as a Space Faring Nation are no closer to mining the asteroid belt and/or the Moon as we were when it was first proposed in 1972…

A diesel-electric locomotive (GE AC4400CW) can move 1 ton of freight 500 miles per gallon of fuel. Rubber tired vehicles have much more "resistance" but the principle is on the right track to a viable solution. Joe
 
If I've understood anything about EVs, the rare earths go in the motors. The batteries don't contain anything that exotic. The rare earths might make the motors more efficient, but I sincerely doubt any improvement will make up for the present limits on battery capacity and charge rate.

Some cobalt is used in the batteries. That aside, you're mostly right.
These threads always render down to the same two things.
The batteries shortfalls.
And the inadequate means to charge them.
Both are deal breakers in an otherwise marvelous concept.
 
Just an anecdote I heard last night. A friend in Md has a very liberal sister who has a Nissan Leaf. She visited him on the Eastern Shore. Lives near (gag)DC. Had the. car on 110 charge all afternoon. 30 miles from his place the car got so low in charge due to a head wind..she turned around and went back to his place...barely made it. Car charged 13 hours. Next day she had to visit a charging station just to have enough battery to get home. He asked how she likes her electric car now. She was not amused.There is no way you could have a car like that here in Wyoming. Funny part...told her next time she comes bring a gas powered car...it's only about 90 miles at the most

I'm expecting that at some point in the future all these free charging stations are going to start charging for the service. Wonder what that's going to cost?

Some You tubers have posted pricing @40 cents a KWH
Our Utility company came out with new energy bylines to follow this summer. It shows green, yellow, orange, and red days. Not allowed to charge vehicles before 10 pm on orange and red days. Like always they didn't explain if you could use public chargers like Tesla on those days? The city is starting to invest in electric buses, does that mean if its a red day, bus service won't run that day?

Of course. They're planning ahead by calling them charging stations...They'll charge you for going there, and you'll be stationary for hours.

I think to make EVs realistic they are going to have to have battery exchanges, like we now have gas stations, where you pull in your vehicle, they pull the battery out and put a fully charged one in. And you drive on. There would be lots of little challenges with eliminating old batteries and passing off defective ones, but certainly not insurmountable. It would be something like propane gas exchanges.

Why can't a 2,000 lb car go 500 miles on a gal. of fuel? If rubber tires have 5 times the "resistance" it would still be 100 miles per gal. Just wondering. Larry
