Why is the photo resolution so bad, even for it’s size?
That sure looks like copper windings around the shaftlike part of the second inset image.
Maybe it’s just a coincidence of color though.
The carbon nanotubes still have to be insulated from each other just like wires, so they used the same lacquer that conventional motors use...............
Now, will it scale up and be reliable and affordable?
Failure to do anything about "depth of field". The focus point can be in only one plane. There are many in that photo, so many that the camera focused somewhere that wasn't any of the three planes of interest.
Photography really isn't "point and click".
How is a “tube” one dimensional?
At least, they defined what CNT is on first usage. Pet peeve of mine when writers don’t do that.

I don’t see anything here about its end-of-life (recyclability and such). Does it burn? Not interested in the functional equivalent of carbon fiber wind turbine blades! Recycling composites is usually a bear.
It looks like they used the tiniest radio-controlled car in the world for the experiment! Asphalt road? For weeble-mobile, that’d be like off-roading on an ancient lava flow!
It looks like they posed three photographs on a counter top. Each photo was taken without regard to "depth of field", then the individual prints were photographed as a group again without such regard.
Looks like someone needs needs to learn how to to "image stacking" with Photoshop.
In the olden days we could focus on the center one, stop down to f32, and use a slow shutter speed.
Looks like a red plastic washer to hold the commutator together.
and that shaft sure looks metallic
No metal car?
Neodymium magnets are 18X stronger than conventional iron magnets, and about 1500X stronger than carbon based magnets.
No, they are not going to have a non metal car. Not so long as neodymium is in the alternator, as it better be. Or in the motors that move the car if it is EV.
HA! I was wondering if anyone else noticed that.
Tiny South Korea discovers something no American researchers have, in spite of academia’s claims that federal funding for the oh so important research they are doing is so necessary. In fact, the priorities of all federal funding for research must be re-examined and many current wasteful grants and their “research” killed.
Koreans don’t have a ‘diversity’ mentality.................
Back in the 80’s worked for a Swiss owned company making precision servo motors ( in America). Reducing weight, better efficiency, and lowering cost were the engineering groups main goals. Things like splining shafts where the laminate stack seated, coming up with lighter insulating materials, and finding the most efficient machining steels ( American made at that time Republic leaded 1040). The good old days when things were being made in America.
