I’ll preface with my qualifications, so if a more qualified person comes along you can disregard me. I’m an engineer who has taken a few thermodynamics courses and has worked as an engineer for a hvac manufacturing plant. I’ve never done anything strictly related to geothermal, but I’ve read a decent bit about it (and watched Technology Connections’ video on the subject, it’s a good entry point)
You may want to call up a company who does geothermal cooling and see what options you have, they’ve gotten pretty creative on how to bury the cooling lines. (See the video mentioned before)
Going the route of just sticking a large water tank underground probably won’t do a ton. I expect that you will have a poor surface to volume ratio, which means poor heat transfer, which means you’ll saturate your thermal mass fairly quickly. What this may allow you to do is run your HVAC system during the night/morning when it’s much more efficient, and ‘charge’ your thermal mass for the hottest part of the day.
Assuming you use 300kg of water in a day, and you can get a 10°C delta, my very rough back of the napkin math says you’re only going to have about 3 kWh of cooling from just the cold water, which is a decent bit, but it’s not a ton. Best case scenario you cut your cooling needs by around 10-20%.
I’m too lazy to do the math of the heat exhange with the ground, but my bet would be you’re better off spending any money you have set aside for this on better insulation techniques and/or a proper geothermal cooling system.
I do like your creative idea though
You don’t matter to the world. You may matter to the small group of people who know you, but odds are you’re insignificant
There could just be no connection at all. Like how there’s a positive correlation between shark attacks and box office sales for Nick Cage movies. There might be some relation between them, but more likely there is no link and it’s just random noise that happens to line up particularly well.
The reason why you might see it used as an end statement is because there is no data or clear logical link between the subjects which were correlated. It’s basically saying “unless you have some reason to believe they’re linked, you should probably assume they’re not”
Perfect control over memory.
So able to remember anything with high detail, but also able to forget the cringey stuff from middle school
What does MKBHD have to do with this? He’s just a tech reviewer who kinda fits between tech normie and tech conservative
