    There is no such thing as a truly “safe and stable” battery chemistry.

    Is it even possible to have energy storage of any kind that is truly safe and stable? Some are better than others, of course.

        Large flywheels are well known to be terrifying mechanical monsters, despite just being a spinning disc

        A couple decades ago I worked at a place that did power generation turbine controls.

        One thing I worked on was a redundant sync check for connecting turbines to the grid. A turbine has to be brought up to speed, about 3600rpm in the US, before being connected to the grid. The sine wave coming out of the generator needs to match the sine wave on the grid.

        If they are mismatched when the huge breaker closes, it’s not a shock or fire hazard, it’s an explosion hazard.

        Dams are scary too, I just hope people are able to decommission them slowly when the time comes. Otherwise the deluge is going to suck.

      On a small scale yeah. The sun heats rocks and they’re able to store heat for up to an hour or so. Cats can attest to that.

      Same with large bodies of water; the ocean, lakes, pools, etc.

        I guess in my head I was implying that it was energy humans store for other humans to use at grid scale. When I said "of any kind” I guess that’s not what I meant, lol.

        So in my line of thinking, you’re right about e.g. using the sun to heat a rock. But if we use the sun to heat something for electricity generation, or we heat some medium for energy storage, I bet that will be pretty potent.

        Besides, past the small scale into the smallEST scale, it’s all just energy anyway, man. 😎
