Good post, further to that one thing it does not take into account is recycling. As an example...only I think the recycling industry is just getting started. Every 20 year plus/minus.....the pv panel industry will recycle due to new efficiencies for their panels. LiO for car batteries...another example. Peak oil was to supposed to happen next year. So I like the visual capitalist a lot just a few factors missing. As for probe..I hope they are assaying for all metals on east limb. News this week.? Doubtful as they are doing a dog and pony show. If they strike on east limb Dave is mart enough to drill 5 to 6 more quick proximity holes and get started on a second resource if it exists. Good luck Time and Tide....wait for no man. Captain time. Till next week.
