Cost to Produce CNTs, page-178

I've got all the botherer's on ignore but saw the reference to ultrasound.

There has been a lot of research into CNT's and concrete over the years and in order to produce test samples a method to disperse the CNT's had to be devised. Ultrasound was one method. The testing showed what could be achieved if CNT's could be dispersed in concrete in a non lab environment and cost effective way.

Maybe there are some here that think we will see ultrasound machines at infrastructure sights throughout the world. Can I ask how many machines would be required to disperse CNT's in a 1km stretch of highway? 20, 30, 40, 50.....? How many machines would a precast concrete manufacturer require to precast 100 beams a day? Could you remove the ultrasonics at 12 hours, 24 hours, 36 hours? That's a lot of ultrasound machines. What does your research show?

To offer ultrasound as a solution and a threat is just stupid and immature.
