Just over a year ago many highly doubted Pyrogenesis when it was trading below $1sp. Seems very similar with HPQ Silicon in same fashion now. This is new hydrogen power applications causing skeptism but I'm more than happy to wait the next few months on 3rd party validation.
I'm extremely bullish still just like I was when many laughed at me early Pyrogenesis days.
PUREVAP NANO NSiR is going to be also spectacular 67% increased production rate recently now with fumed silica yet another multi billion dollar business line.
Also 2N+ purity is more than enough for EV batteries via NSiR. Fumed Silica market is massive...much bigger than most realize.
As Bernard stated, all sorts of claims at lab scale but commercializing at low cost has not been achieved by anyone to date to make it viable. Bernard also recently stated they are 5 years ahead of anyone IF they had a Pyrogenesis which they do not.
Purevap NSiR reactor to produce @ $10-20/kg graphite pricing for the EV battery market but could very well get a premium as the capacity, density etc is significantly increased. No one to date can achieve this price pt.
Plus Purevap QRR reactor gives an obscene advantage as cheap quartz feedstock can be transformed into 2-4N silicon in one step....this alone puts us leaps and bounds ahead of anyone trying. QRR is gunning for low boron 4-5N purity Si which would be mind boggling incredible to do this in 1 step from cheap quartz feedstock.
Plus don't forget other applications like silicon nano-powders medicinal delivery etc. could go for way higher prices. Those sub 100nm could really have lot of high value $$$ applications.
Pyrogenesis tech and engineering has already proven they can scale. PYR CEO stated numerous times they are highly confident they will scale Purevap :)
