Could the bubble of Earth under the plastic around a Wofati be viewed as a passive climate battery?

Yesterday I watched a video about  (building an almost tropical geothermal climate battery Greenhouse)
They go into some detail describing how a climate battery works versus geothermal.

I kept thinking about it..

In the video I don't think that the earth part of the climate battery is in any way separated from the soil around and under the greenhouse. Air is forced via fan into the tubes that go through the battery down below the greenhouse. It is used to provide some cooling during the summer time, but more importantly it is used to keep the greenhouse above freezing during cold weather. It uses an active system, Motors and Technology to move the temperature transfer medium (air) through the tubes to give up heat or collect Heat. It is 'active' .

The Wofati has a water resistant layer over the soil closest to the structure. As well as possibly some slight insulation in the form of protective carpet or other material guarding the waterproofing layer. But that dry soil is still connected to the soil below it.
I thought that I read something about the temperatures in the first wofati (Allerton Abby?) Fluctuating in the first couple of years but then gradually evening out, possibly because the soil Behind the Walls finally 'charged' enough to reach a sort of equilibrium?

I wasn't sure where to ask this question, but when I did a search, this forum had a bunch of mentions. So I figured that asking a bunch of people that are building structures that use these processes would be a good place to start.

If there is another Forum that this should be moved to, please let me know.
Thank you everyone in advance, my brain sometimes chews on stuff and won't give up and I really am curious about the answer to this.

Love this!

I once got a whole box full of expired coffee packets from a gas station down the road. It was a pain to open them all and keep the garbage from blowing away, but I simply used it as a soil amendment in the fall on my garden and sprinkled it around without bothering to add it to my compost pile.

There is a difference between unused coffee grounds and used coffee grounds as far as the PH goes... I just can't recall which is which right now. Anyone else know?

Thank you. This is a container that was opened ( seal broken) and then forgotten in a cabinet. I would guess that since coffee is acidic, unused coffee probably leeches acidic pH?

I've also heard that slugs and snails don't like coffee grounds and will not crawl (slide?) over it if they can avoid doing so. I have tried to create rings of coffee grounds around sensitive plants but, to be honest, I've not noticed much of an effect.

A final thought is that it may be good for disguising plants for whom the pests discover by smell. Carrot root fly, for example, is famous for smelling out the carrots that it lays its larvae in and people often use a guild of aromatic plants, such as marigolds or garlic, alongside the carrots to discourage the fly. I wonder if coffee grounds in close proximity to carrots would help too?

Ooo! Sounds like it could be used as a top dressing? Even if it doesn't help, it probably won't hurt.

Thankyou.

Unused coffee, I'm pretty sure I can compost it without a problem? Is there a better use for it? Like, could it repel Garden pests or something?

A couple of days ago I was offered an opened can of coffee that had been left in the back of a cabinet for several years. I'm not a big coffee drinker, so I don't know how long coffee is good after it is opened but certainly it can't be good if it's several years old? Probably pre-covid? I took the can knowing that used coffee grounds are popular in compost, so I'm pretty sure that it would be fine.
But I got to thinking about it, and realized that there might be better uses for stale coffee.

It is the "Chock Full O Nuts" brand, if that makes any difference.

That sounds very inexpensive.  How long have you owned it, and how is it zoned?

Loveland? I'm in Cincy!

Holy cow! I was noodling around on the site and saw this topic, I started to read.

So yeah, I am bumping this thread, because as I started to read it I thought it was a new thread that had been started because of the devastation from Milton and the previous hurricane a few weeks earlier.

Then I noticed the dates on the replies. Yeah. This could have been posted yesterday.

Is it still this bad? (Wincing)

I'm standing in the thrift store and had an idea pop up while I was in the back corner staring at all of the random high chairs wheelchairs strollers Etc.

I am staring at those hinged pet fences. And it occurred to me that those might work really well for a composting bin. Especially for winter storage of fall leaves. Any idea why this would not work?
I can easily see how to make a two or three spots composting station.
I'm looking at a zip tied bundle of six panels for $15. They are some sort of plastic, probably HDPE but I can't tell for certain.

I already have a pet fence that I have lining the driver's side of my driveway to help protect the edges of the car door from the rock wall. At the time I had not realized what it was I thought it might have been some kind of toddler fencing.
