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. 😎
