Oxidation-proof copper could replace gold, meaning cheaper chips, says prof

Re: Will this be any use in practice

I just read that there is about 0.1g of gold in a CPU chip and I expect they have more than most. So at $62 million per tonne, that works out to about $6.20. If the copper was absolutely zero cost, your stick would come down to about 377 pounds. Might make more difference on cheaper things but they probably have less gold in them too
