Okay I understand you cant answer this question but it still baffles me how you can run the QRR 24hrs a day. Its impossible to add and remove material to a vat under vacuum. But maybe you can shed some light on these two questionsÂ
1. How large is the feed stock I would think you would have to crush it fairly fine as not to damage the vat?
2. I work alot with gold and silver and to get the impurities out of them you heat them up to a molten state and skim off the impurities. How do you do that under vacuum or is there a temperature where the tourches vapourize everything except silicon?
Not expecting an answer but I just like figuring these things out
