PYR/HPQ have produced silicon nanopowders at laboratory scale, but they need to build the nanoPureVap to produce enough powder to send to potential customers.
But fortunately, the nanoPureVap is under construction, or rather, being modified and PYR said in its latest release that it will speed up the process in HPQ silicon powder because it is NOT fast enough for them.
Don't forget, it's PYR that builds the PureVap for HPQ but it's HPQ that holds all the patents on the nano silicon powder. And PYR owns, I believe, 10% of HPQ's revenues.
