PyroGenesis filed a new patent application regarding nano Silicon:
 
NANO-SILICON PARTICLES/WIRE PRODUCTION BY ARC FURNACE FOR RECHARGEABLE BATTERIES
 
https://patentscope.wipo.int/search/fr/detail.jsf?docId=WO2021068054&_cid=P10-KNIVER-47877-1&fbclid=IwAR0Zs0Ko9sxWM6zWmIQN_IIBdJaju1_AAS_xJ9CGPoLGAR2BpE949Td_CY4
 
A process and an apparatus using pure silicon as raw material with no other pre- processed material for producing nano-Silicon and/or nano-Silicon-carbon coated composite material in the form of particles, nanowires or a combination of both, for use in a high capacity and high energy efficiency manufacturing of anodes for Lithium-ion batteries. The apparatus comprises a reactor including at least one electrode and adapted to provide at least one arc, e.g. a DC transferred arc, for melting and vaporizing silicon provided in the reactor. A quenching system is provided for delivering a gas for quenching, in the reactor, the so-produced silicon vapour so as to form nano particles and/or nano wires. The reactor is under vacuum. The gas can be injected by a vortex and/or via the electrode that is hollow. The electrode is consumable and vertically movable to control an arc voltage and to compensate for electrode erosion.
 
Exciting times!

Long and Strong in PyroGenesis and HPQ Silicon!

Thank you for sharing!  Looks like this would bode well for HPQ.

Great Post... Their patents are ever increasing and solidifying their disruptive technology. But wait, your detractors will attack, redicule, chastise, spite and even curse you for sharing with potential investors. Bear in mind that I, for one am not up to date about PYR and HPQ. So, thank you for your post.
