Air pollution?

Sky's turned blue,, possible cause yellow disc emitting light and heat,,😄

Sounds like global warming to me....

Air Pollution to me was the fogs and smogs of London before the smokeless zones were brought in.
I read this in an article a while back. Is it true ?? I hope not 🙉

A 2021 study found that lithium concentration and production from brine can create about 11 tons of carbon dioxide per ton of lithium, while mining lithium from spodumene ore releases about 37 tons of CO2 per ton of lithium produced.12 Feb

It may well be true, but I have not searched for a source.

If it is , then a 100kWh battery (a big battery, good for well over 300 miles of range), which contains about 63kg of lithium will be responsible for 2.3 tonnes of CO2.

1 litre of diesel when burned will produce 2.6kgs of CO2, so burning 884 litres of diesel will also generate 1 tonne of CO2.
At 50mpg, that's enough diesel for just under 10,000 miles.

This does not include the CO2 costs of battery manufacture from the raw lithium, or the CO2 associated with charging the battery. But, it also does not include the CO2 associated with extracting the diesel, refining it and getting it to the pump (640g/l well to tank for diesel).

If you feel like exploring the data in some detail, I can recommend the Polestar Lifecycle assessment report for the Polestar 4. It has real figures on the environmental costs associated with both manufacture and use of the car.
