Cost to Build a Solar Silicon Plant - Quote form articlehttps://investorintel.com/cleantech-intel/hpq-silicon-resources-inc-orders-plasma-pilot-plant-for-silicon-metal/ In this article I quote this: "A new traditional 16 K TPY Solar Grade Si and/or Polysilicon plant requires investments between US$ 900M & US$ 1B but HPQ stated that Capex of a 10K Mt per year of solar grade Silicon and/or Polysilicon is roughly US$ 50 M, which is five percent (5 %) of the cost of current solar grade Silicon and Polysilicon industry Capex." So the cost for a solar silicon plant with PureVap tech is likely less than $100m for the comparable plant (Siemens) that costs $1b? I thought before it was $200m but this number is just outstanding! This technology they own now is - so valuable. Look at the current market cap - crazy.
