Nice additional benefit!
Spending 3.6 million now on an element that' "may or may not work"?
I'm pretty certain it already works and this additional spending implies the QRR will work (pour silicon continuously under vacuum).
Why else would you spend that 3.6 million dollars now if you don't even know if the QRR will definitively work ?
Pyro does need the cash infusion. HPQ not really rolling in it yet.
