The paragraphs seem fine to me, they are separated in easily consumable chunks so you don’t get lost (at least on computer). I also like your structure, very straight forward. If I had to point something out, it appears to me that the disclaimer and intro provide the same gist but differently worded.

I assume Toes is asking for a TL:DR or summary in bullet point format. I’m not sure if I agree that this review is long enough to warrant a TL:DR, nor would profit much from from being made more concise, but those are just my two cents.

EDIT: While I don’t necessarily agree with Toes on article anatomy, most of us here should be grownups. Differences in opinions are to be expected, so let’s be civil and not downvote or throw jabs without reason. How about people make a comment instead, or just upvote the comment they agree with if it’s already there? I find that this results in a much more enriching experience.


Right, my bad. I thought you were explaining turbines in relation to the post, which would indeed have one attempt to run sand through it if not used with either liquid or steam.

I also wrote turbine and generator separately, as, as you stated, turbines and generators are not the same. I, in turn, hope I didn’t give the impression that they were.

I fully agree about the system as a whole better being described as a battery, which usually includes generators of some sort to convert the stored energy back into electricity.

And yes, this is a rather precarious article, which also is why I wrote the half-question half-joke about unnecessary conversion steps using turbines.


And that’s my confusion, why use a turbine (connected to a lift) to turn the heavy weight into a flow of steam or liquid, presumably to convert this flow to electricity using another turbine with a generator connected to it, instead of simply converting the heavy weight to electricity using a lift (or corkscrew) to turn the generator?

This is, of course, assuming that a turbine only is a turbine when it is driven by steam or liquid.

I guess the publishers of the article either got the definition wrong, or there’s a less used definition of turbine which I am not aware of.


But isn’t the definition of a turbine “a type of machine through which liquid or gas flows and turns a special wheel with blades in order to produce power” with the “power” (aka. rotational energy) going to a generator?

Where does the liquid or gas come from? Isn’t this battery supposed to lift heavy, solid objects?

It doesn’t outright state that it uses solid weights, but their illustration looks more like they’d use a lift with sand or weights, and not a turbine with liquid or steam:

Very interesting, and good to hear.

Though, I’m not sure why they would drive a turbine to drive a generator, instead of just driving the generator directly. Their illustration doesn’t show any turbines either.


They didn’t even use pictures of the cases, they just write about gardening with a picture of proper gardening tools.


I have no clue why you had to include an image, but it appears you broke rule 6 in doing so.

I haven’t owned many tablets so far, but can’t you get some tablets with SIM-slots? What would prevent one from just using such a tablet as a phone?
