That's a typical PMF disparaging comment on Edencrete.

ROTFL. Dispersing CNT into an admixture can be as simple as using a surfactant (dishwashing liquid) and ultrasound.

Don't forget everyone - the method EDE has to disperse the CNT rated applying for and being granted a patent.

There are numerous patents for dispersion CNT in concrete and vastly more non-patented methods anybody can use. The processes are all relatively basic industrial chemistry. They aren't major breakthroughs. Eg this patent by Northwestern University was lodged in 2008 and has been extended to 2029.

Small companies like to patent things because investors are under the false impression that patents are extremely valuable and prevent others for developing similar technology. The US Patent Office says only about 1 in 10,000 patents are highly valuable. The vast majority are worthless.

Is this sort of comment from PMF unusual? - no - it is typical and is the reason IMHO PMF has blown all residual credibility he might have had.

I've effortlessly torn to shreds every baseless claim the holders have made so far.
