In one of the iterations of my idea, I thought of using solar energy to compress air and keep it stored in an underground tank. But it felt more hazardous and prone to failing. I'll explore the link in the other reply to your comment and reconsider it. Thanks.

Thanks for mentioning the terms that I should look for. I never had the opportunity to study these and having these as pointers helps a lot.

Thank you for your reply. It has given me the factors to consider and the terms to look for. I'm going to cross verify the values you have quoted and if it is indeed as bleak, I'll just temper my expectations.

But I'm not giving up on it totally yet. What I'm still not sure is how geothermal cooling can provide more heat exchange as compared to the system I'm proposing. At most geothermal systems also only have a few tens on meters of piping underground.

I have been considering newer construction materials and the trouble is that most of the material available online is either research papers or companies selling it: both of which only talk good things about it.

I liked one such tech and intend to seek and meet people who are living in houses made using it. That should definitely assuage my doubts.

I can't thank you enough for taking the time to write all of this. I have come across most of these concepts and have been considering them with respect to the options I have.

I'm trying to design the house considering the natural air flow and sun angles. There is a garden with trees on one side of my plot and I intend to make use of it while also planning for other sides. Currently I'm making house plans on my own and discussing with some people I know. This is helping me understand what we want/need, or not, in our home. At some point I'll definitely take it up to the professionals. There used to be a community of floorplaners and home builders on Reddit but it was not much active.

Stone is the cheapest construction material in my area but it practically converts the house into a furnace unless the walls are very wide. I plan to avoid it at all costs. On my radar is a technology called EPS (Extended PolyStyrene) Core panels which are nothing but high density PolyStyrene with a galvanized steel mesh in it. It is supposed to be load bearing and good enough to build the roofs along with walls. It has been used in some countries at various levels of success though not in this exact form (with wire mesh). It is supposed to be highly non conductive in terms of heat and so good for maintaining inside temperatures with minimal cooling. Most of the material available online are either research papers or companies selling it, both of which only have the incentive to talk good things about it. I intend to go and meet people who have actually built using this technique and take their feedback before I commit to it.

As regards this pet idea of mine, I think the consensus in this discussion is that it will not cause much difference. But since it does not involve much effort/investment, I'm going to try it anyway.

Another cooling technology that has my attention is desiccant based cooling. That too has some research papers and a nice set of videos by Tech Ingredients (https://www.youtube.com/watch?v=5zW9_ztTiw8). It looks more daunting and more suited for humid regions/months.

I keep dreaming about a setup with evaporative coolers for dry spells and desiccant based thing for humid ones, assisted with this pet tech of mine.

I hope I'll have the courage to implement these ideas finally.

Thanks again.

As regards your point on the budget, i don't think that two car radiators, some insulated tube and a small water pump will cost much, more so if I can run the pump off a small solar panel in the day time.

All said and done, if there is nothing in theory that advises me against trying this, i would like to give it a shot and document it so that someone else might learn from it.

Thanks again!

Thanks, hoping that your back of the napkin math is in the correct ballpark, 10-20% lowering of cooling bills sounds very lucrative to me.

And I owe a clarification after reading your analysis since I'm not hoping to achieve any geothermal gains by heat transfer between water tank and ground. I'm assuming that the water will heat up as it cools the room down. But since fresh water is supplied periodically and this fresh water is relatively cool, it will keep the cooling cycle running. I will try to build the tank in shade and isolated from direct heat of the sun as far as possible.

I think it is different from swamp coolers since swamp coolers constantly add moisture to the air in the room which is okay for arid conditions but does not work as the air increasingly becomes saturated with moisture. We use swamp coolers when we can in the initial part of the summers. But they become useless once the rains arrive and the air turns humid.

In the contraption I'm suggesting, does not expose water to the air inside the room. It will work purely on heat exchange principle.

Plus one to ViMusic. High quality music with a beautiful interface and customisable buffer for music you heard previously. What's there not to like?

Does Immich support deduplication of images? I have a large set of old scanned photos that I put on photoprism that has deduplication listed as one of its features. It puts photos in its own database.

Also, how is the face recognition of Immich when compared to others like photoprism?

You'll probably also need a speaker to connect to the monitor to make it sound good. Long ago, I set it up on a 23" full HD monitor back when even 32" TVs were not full HD.

I met all of you cool guys here. Witness me!

Kevlar fibers are also used commonly in rocket/satellite manufacturing.
