I found some very interesting and very recent link: https://hackaday.com/2021/09/30/the-coming-copper-shortage-aluminum-or-carbon-nanotubes-to-the-rescue/ https://hackaday.com/2021/09/30/the-coming-copper-shortage-aluminum-or-carbon-nanotubes-to-the-rescue/ . Now consider this that our BORK was supposedly doing some tests on the subject in 2012 already: http://ih.advfn.com/stock-market/USOTC/bourque-industries-pk-BORK/stock-news/54857565/bourque-and-sichuan-aerospace-partner-to-create-ne http://ih.advfn.com/stock-market/USOTC/bourque-industries-pk-BORK/stock-news/54857565/bourque-and-sichuan-aerospace-partner-to-create-ne . BORK also is holding maybe some relevant patents with priority dates. Price of copper was relativly low but it is changing already and with this new green economy it can change drastically.So there is some chance our BORK can be huge!
