I'm not that impressed. The bar appears to be about 1/2 inch by 1/8 inch by 2 inches. A similar sized steel bar would weigh 1/2 oz. Using properties for 17-4 PH steel (which I'm familiar with, without having to look it up), it would support at least 2000 lbs. in shear, the manner shown in the video. That's 32,000 times its own weight.

Note, though, the manner shown in the video was quite imprecise. I believe when tested properly, the carbon nanotube could support much more than was shown.

I agree with you statements. In particular, your numbers are accurate.

But most people don’t know these things and therefore are easily fooled.

That said, I do believe this tech has potential.
