the thing I mostly noticed from ??? what did they call it - Tesla day or something - only a short while back -
was the Lithium upgrades ------------- impressive
I remember what must be now a few years back - when Musk was building or planning his giga factory - he said that they just didn't know what they would be building in 5 years time - that Lithium might be gone by then - but, the factory would be able to be converted to whatever the new kid on the block was
well, that's a long time back in history now really - and, Lithium ??? well, it probably looks like it's got a more cemented place in the near future than it had back those few years - it's really kicked on quite well
