Have a credit card? Own any cassettes or 8-tracks? The mag stripe and ferrite layer on tape are programmable magnets. The only thing that has changed is the remenance of the magnetic substrate. Make a strip oit of REE based magnetic material, magnetize it in a repeating pattern, and you could make a linear motor.
That’s interesting
The motor is powered by internal magnets. Science and Mechanics had an article on it in its Spring 1980 magazine. It was denied a patent because it appeared to be a “perpetual motion machine” but Johnson proposed a different theory on magnetism and finally got a patent #4,151,431.
With printable magnets a machine would be much cheaper and powerful.
Does a magnet ever lose it’s magnetism?
I'm still trying to digest the fact that 100 trillion neutrinos are zipping through my body every second
.
As you know there is only so much energy in a gallon of gasoline. Most of the inefficiencies in an internal combustion engine have nothing to do with carburetion or fuel injection for that matter.
It is a little like the oil burner in my old furnace. If you tune the oil pressure and air mixture for the size of the orifice in the nozzle you can increase the efficiency. But even if all the fuel is burned as completely as possible since my furnace is old, a larger percentage of the heat is still going up the chimney compared to a newer furnace since the heat exchanger technology has been improved quite a bit in the last 40 years.
Very cool. I’m sure they are just printing a magnetic polymer and polarizing it as the layers are created so it’s something pretty basic at heart, but hugely clever to have thought of it in the first place, and lots of patentable applications.
Remind me what day it is tomorrow, I forget.
You DO know I was joking about the mythological 100mpg carb, right?

Here are some of the documents of the patent. Kinda interesting.
So you don’t believe in the zero point field?
The only perpetual thing I know of is a woman nagging her husband with no indication of ever winding down.
There are lots of patents for perpetual motion machines that don’t work.
A patent merely need be novel, not practical/functional/realistic.
Across your open mind
I trace erratic lines
In motion and in time
I fought a battle won
To the surface of the sun
Through fires on and on
I am the little neutrino

Yes permanent magnets lose their strength over time, some types more than others. I have an antique phone magneto that despite being nearly 100 years old seems to work almost as well as it did when new, this is because of it's design. Many magnets come with a “keeper” that you put over the poles that helps preserve their magnetic strength by completing the magnetic circuit. The armature in an antique magneto served this purpose so they last a long time.
I knew but wasn't sure that everyone else did.
[[Perpetual motion machines dont, and cant, exist.]]
Nonsense, I had three of them I just sold at a yardsale last weekend-
That was never denied in the patent.
From what I have read, standard iron magnets decay in less than three days in these devices.
