    You think the toxic (deadly) lithium thermal runaways that can’t be stopped are somehow better? No. They are worse and a deadly underground carpark disaster waiting to happen.

    Yup, all those trains waiting to explode in carparks. Nor are we developing better batteries that don’t have these problems. Nope, just leaving things exactly as they are.

    Not enough lithium in the world to supply the global suv market . . .

    Even if lithium was our only battery option, this is just plain wrong. People misunderstand what “reserve” means in mining. It’s not the amount of something that’s available to be mined. It’s the amount that is available profitably under current economic conditions. Both better technology and other shifts in the market mean more reserves “magically” open up.

    Oceanic lithium mining may already been commercially viable, and the amount of lithium we can get from that is basically unlimited. On the lab side, there’s a promising string-based evaporation method, which would substantially reduce costs and environmental footprint–exactly the sort of tech that makes more reserves open up. It still needs to be demonstrated at scale, but the strings involved don’t use any exotic materials or have any difficult production.

      I wish they gave a $ per KG estimate in your link about harvesting with strings. The methods detailed in this Journal article gives estimates of $2-5 per KG which is like a 5 to 12x return at current prices.

      I wonder if you could couple that string method with desalination plants? Take the brine output, extract the lithium with the string method before releasing back into the ocean. Two birds one stone sorta deal. I also wonder if the string method is as technically easy to implement and separate the end products, and it’s just a lot of labor if this will end up economically benefitting countries with extremely low wages. If so, that could be ecologically very bad, especially if it’s possible to do with salt water brine. (As it could incentivize people to pump ocean water inland to make brine pools for harvesting).

      The fact you couldn’t put the recent derailments and toxic unstoppable fires together shows clear ideological bias.

      “Developing” cool so 5 years? 10 years? For these super safe “in-development batteries”. Neat. More clear ideology borderline fantasy.

      “Reserve” Hahahaha More fantasy. Demand has never been higher but don’t worry. “Reserve” will save us all…

      “Other technology” “Profitability “ hahaha good god how much of a fantasy are you selling.
