RE:The lengths some will go to produce "green" Silicon NP... Thanks Sabbathlife,
Very good video and a good proof that we (HPQ) are on the right track. Obviously the researchers at University of Liege in Belgium are sharing mind expansion information and research.

I applaud these researchers for their work as this will significantly help the industry out but as advanced as they are they will still be second to us. The only few things they fall short on are;
-Relying on decommissioned PV material which is also not the greenest material to begin with, but good for them to recycle and find value.
-They end up taking a very pure Photovoltaic Silicon and lowering the grade down to 99% Si through a bunch of chemical processes and then ball milling the low grade recycled Si into irregular shaped micron powders.
But my goodness there is a lot of gems in this video for investors such as Micron sized low grade Si powders selling for 300-700€/kg (98-99% Si >100 nanometers).
It also gives you a really good idea of how many steps and, not to dismiss the incredible PYR Engineers complexity, the simplicity of PUREVAP QRR &NSiR, and the Capex it reduces for SiNP w/ carbon coating production.
Oh and crazy how many markets they want to attack with their recycled SiNP's; material for health, material for energy, material for recycling, ceramic 3d printing, powder for food, mining and metals material... congratulations to them for recycling PV material, hopefully their chemical process on stripping materials down to a recycled silicon are environmentally friendly... but most of all thank you for this gem and reaffirming the superiority of HPQ PUREVAP high grade, high quality, high value, resource abundant tailor-made Silicon.
Ouu. I almost forgot that the battery data for SiC anode near the end of the video sure looks pretty good... I'm sure PYR engineers will like to see that if they haven't already and eager to pump that Silicon cocktail out NSiR, if they haven't already haha...
