Cost to Produce CNTs, page-200

A pretty good summary IMO.

I have never said that CNT admixture doesn't work. I've said that CNT admixture is a generic product and Edencrete is really just a brand. Other CNT reinforced concretes have very similar performance levels to Edencrete when they use the same amount of CNT.

IMO CNT reinforced concrete is at least 10-20 years away from mainstream use. The CNT supply needs to increase by a factor of at least 100 (to 200,000 tonnes pa) and many years of field testing will be needed before engineers start using CNT concrete for critical structures.

To put things into perspective steel reinforced concrete was invented in the 1850s. The first multi-story concrete buildings were constructed around 50 years later in the early 20th century. It took until the 1970s (120 years) until concrete became the preferred method for constructing bridges and high rise buildings.

IMO EDE is just another one of the many interlinked speculative penny stocks controlled by the Solomon Brothers. I'd be interested in knowing the overall success rate of these businesses but I suspect it is extremely low.
