Besides peak oil, we may also have peak platinum. The global production rate is currently 130 tons, most of which is used for jewelry, medicines, and to supply the losses of catalytic convertors.
Our current yearly uses are as follows
230 tons total
with the following breakdown
35.5 tons for medicines and related manufacturing equipment
78 tons for jewelry and investments
113 tons for car catalytic convertors (enough to make approximately 37.7 million cars), assuming 3 grams/catalytic convertor
Remainder 3.5 to other resources
The 35.5 number is very inflexible and the 78 will probably increase, if you do the math, that means 1 person per approximately one thousand is buying one platinum ring (11 grams) per year or one person per 2500 is buying a platinum coin.
My concern is that with regular cars we do not have enough meet the Clean Air Acts in the respective countries and it would be very disappointing for the countries to ease the regulations due to a platinum shortage
Another compelling reason to switch to EVs
