Flexy Wires Stretch to 14x Their Length

This is misleading. The conductance (mhos end to end) stays constant when the cable is stretched. In a normal material, the end-to-end conductance would decrease (increased resistance) as the material was lengthened and became thinner with stretching.

The reason the resistance is constant is that the carbon sheets making up the cable are "scrunched up". They straighten out when the cable is stretched, so the conductive path is the same. Nothing magic about it.

The use of the terms "Conductance" and "Capacitance" in this article, are confusing.

"This is misleading."That's an understatement!

"...using their wires as capacitors which, when elongated, boost their energy storage capability by 10x" There is definitely something missing here. Perhaps two layers of the stuff...

"lighter-than-air" Yeah, sure! At atomic weight of 12, the spacing of carbon atoms in the matrix would have to be more than 41% of the average spacing of air molecules (molecular weight≈29). Clearly, a one-atom thick sheet of anything is incredibly light, but it is essentially 2-dimensional. How many layers does it take to fill a cubic whatever?

Somehow, this whole article (not necessarily the University where the research was done) has the distinct aroma of B.S. (not meant as disparaging remark against Bevo, just saying). If the wires can be stretched and maintain the over all resistance as before that is good. If there is a capacitance (which I fail to see how), if that increases with stretching, it still cannot overcome conservation of charge, thus if capacitance increases, the ratio of charge to voltage must concomitantly change accordingly, thus either charge must go up, or voltage decrease. Where would any extra charge come from? The ether? Obviously, the voltage must decrease.

"which are built by wrapping lighter-than air, conductive sheets of carbon nanotubes..."

So, the wires should float, too.

That's the ground that's floating... :) -smileys not working!

I would just like a wire (like the one that I just cut short)that could just stretch the extra 3 inches to reach the terminal in the panel that I am wiring.

I did that once and when I went to the other end of the conduit, THE WIRE WAS GONE!

Ah yes, I remember the old Heath Kits. If they said cut a wire 2 1/4", 2 1/8" wouldn't reach!
