Big fan of gravity well storage, it seems simple and elegant. https://energyskeptic.com/2019/gravity-energy-storage/ https://energyskeptic.com/2019/gravity-ener

  That website is full of deranged ramblings which are largely disconnected from reality. Case in point: > MY NOTE: well whoop-dee-doo. China generates 16.2 trillion terawatt-hours (TWh) a day. That’s 64 billion times more than all of the open-cast mines can provide. Better start digging more holes! 16.2 trillion terawatt hours a day is ~4 million times the total global insolation or 35 billion times total global energy usage. This is more wrong than asserting that a single man on a bicycle generator could produce our entire primary energy worldwide.

    Thank you for letting me know! Did a bit of checking and deleting this from my bookmarks!

      I find it's a useful barometer of what crazy disinformation is going to be spread next because it has been SEO'd so well. It also often covers interesting topics, and many of the stories are actually about something important or useful. Additionally many of the things it 'debunks' are actually terrible ideas, and some of the arguments it uses are valid. For gravity storage the costs and inefficiencies are a bit prohibitive for the use case of an unsubsidized high capacity (more than 1 day) option, and it's not really competitive with batteries for less (and is highly power limited).
