The real question I would like answered by ZEN is what happened to the testing with Larisplast.  The last NR (dated May 25,2017) said they were stariting testing 5-10 tons of concrete with 5kg of ZEN high purity graphite.

What happened?  Did it work ramping up higher volume?  Did it not work?  Did the testing of the concrete come back different than the first tests?  Did it work better than anticipated?  Or not?  Have they moved on to something else?  8 months and not a word.  Same with the testing Ballard has done.

This is what irks me most about AE and ZEN.  The complete lack of any follow up to these tests and NR's.
