Some FUD posters claiming HPQ hasn't done anything in last 7 years...don't let them try to steal your shares. ...very brief points to note and bashers hate being re posted:
 

SET TO DISRUPT SILICON MANUFACTURING

How significant is this development to the global silicon manufacturing market?  CEO Tourillon stated:

“With the PUREVAP TM GEN3 QRR pilot plant functional, HPQ is ready to disrupt Silicon manufacturing, an industry that still relies on a traditional process developed in 1899 to make silicon.”

SILICON PRICES SKY ROCKETING

And $HPQ timing couldn’t be better as the price for 1 metric ton of Silicon, as of the end of 2021, reached US $10,000 compared to just US $2,500 a year ago

Beyond lab scale - Pilot Plant proof of scalability

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.

NSiR Production Rate

I'm extremely bullish 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.

Fumed Silica

Also 2N+ purity is more than enough for EV batteries via NSiR. Fumed Silica market is massive...much bigger than most realize.

Price point production

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.

QRR Purity in 1 step

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 :)

Purevap Nano NSiR reactor is really in the right space at the right time. Pyrogenesis tech and engineering is seriously over the top. As Bernard stated his goal is not to be a supplier BUT THE SUPPLIER of silicon nano-powders and nanowires
