"These structures, so minuscule they cannot be seen, are stronger than diamonds."

Strength measured how? Diamonds can shatter and break, it's only hard to scratch them. Metals won't shatter so easily, but they may be scratched.

>>>"The pulsing nanotubes reflect light waves like a car reflects the sound waves from a police radar gun. As the radar gun measures a car's speed by the frequency of the sound waves it reflects,"<<<

This author has SONAR and RADAR confused, RADAR would be RF Energy transmitted and reflected back to the Transmitter and the resultant round trip time would be used to determine distance this distance measured numerous times from which a closing speed can be calculated (Relative Speed to the Transmitter), with Sonar you can perform a very similar calculation but the medium that the sound is traveling in must be identified measured and taken into consideration since the properties of sound are affected by things such as density, temperature, pressure and the properties of the sound that is transmitted itself (frequency, amplitude etc)

Sonar would make a very inefficient instrument to measure an automobiles speed.

I was discussing this with my grandchildren last evening. They loved it as a bedtime story........
