The "
rabbit" that PYR's CEO is talking about is probaly this one, taken from the Sept. 17 press release:
HPQ and Apollon Solar Extend Agreement to Work on Porous Silicon for Batteries and Expand Collaboration to Include Hydrogen Production The addition of manufacturing hydrogen by hydrolysis to our collaboration opens up a new and unique business opportunity that could represent a second multibillion-dollar addressable market for the PUREVAPTM Nano Silicon (Si) Reactor (“NSiR”) nanopowders.” APOLLON PROCESS: MAKING POROUS SILICON MANUFACTURING ECONOMICALLY VIABLE
Porous silicon is a Silicon (Si) structure in which Nanopores have been formed by electrochemical etching. Addressable markets for porous silicon are substantial, but existing electrochemical etching processes require very pure Silicon (Si) feed stock (9N to 11N), making porous Silicon cost prohibitive.
To make affordable porous Silicon, Apollon developed and obtained a worldwide patent for an electrochemical etching process that can use (2N to 4N) Silicon (Si) to make porous Silicon wafers.
AIMING TO SEND POROUS SILICON NANOPOWDER SAMPLES TO END USERS BY DECEMBER 2020
Mindful of HPQ's competitive advantage, the ability of PUREVAPTM QRR to produce 2N to 4N Silicon (Si) at the lowest cost in the industry, HPQ and Apollon are busy manufacturing samples of porous Si nanopowders of different sizes (2 nm to 1 µm) with porous structure sizes of either Microporous (<5nm), Mesoporous (5nm – 50nm) and Macroporous (>50nm). The aim being to send samples, to end users’ specifications, by December 2020. The extension of the agreement continues HPQ’s North American exclusivity over the use of Apollon's patented process to manufacture Porous Silicon until at least December 31, 2020.
