Good advice always has its exceptions. But in general you should never use a work device for personal use because it’s very easy for that information to be either compromised and/or used against you.
My personal guidance is “if you don’t own the device, pretend the owner is looking over your shoulder” it’s incredibly easy for them to install keyloggers and trackers remotely and silently.
Isn’t there a black mirror episode about someone experiencing a terrible fate because of a malfunctioning brain implant that just got FDA approval?
Well there is plenty of reason to not do it, but I’m assuming you’ve thought about what tampering with your water supply means (and that car radiators are not food safe, and could contain lead or other nasty metals). I think it goes without saying you’re also running the risk of leaks, a high water bill, and mornings without water if your system has issues.
I’d also like to cover my ass a little and do the typical engineer thing and remind you that an idealized number like this is never realized. You will have to account for losses due to inadvertent and incomplete heat transfer. But you may also get a higher reduction due to the ground heat exhange, which I am still too lazy to work out. ¯\_(ツ)_/¯
All of that said, I really hope you succeed at getting cheaper cooling and have fun doing it. There are houses which use water piped through concrete flooring to regulate temperature, so you’re not very far in uncharted territory. Doing big projects like this are also a really good way to learn a lot very quickly.
I also still highly recommend getting a quote for a reputable geothermal cooling system. If nothing else but to brag about how much you saved by DIYing
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
It may depend on the store. My local publix trains it’s employees like Chick-fil-A does, and they probably would be offended if you didn’t let them help you.
The baggers at my local food lion (if there is a single one in the store) are offended that they have to help you at all (probably because they’re expecting you to be the fifth person today to come back in the store demanding a refund for the one cracked egg in their dozen)
You answered it for me. This is exactly what I was thinking.
You are right, I overlooked units when making sure I wasn’t off base.
I’m nearly certain that camper is way over that car’s tow capacity. If so this is dangerous and stupid. Drivers like this, who endanger everyone else even near the road for their inability to use common sense, should be banned from society.
Edit: I did fact check myself before spouting off, but I made the common error of not checking units. The golf towing capacity I looked up was shown in kg, but the weight of typical campers was shown in pounds. I withdraw my slap judgement.
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
What does MKBHD have to do with this? He’s just a tech reviewer who kinda fits between tech normie and tech conservative
This guy proves that being smart is not a prerequisite for being rich.
A good, comfortable, dust mask. And wear it when you’re making fine dust (mainly sanding)
A good dust remover would be a nice addition also.
The first time I think it lasted 24 hours (April fool’s day)
The second time (last time) it lasted for three days I think.
We can agree on what the words mean individually, but an NFT is not just some physical item which is unique. NFTs are unique and are only possible to transfer if you have the private key. So saying that your credit card number is an NFT because it’s a token which is non-fungible is missing the point, and being intentionally obtuse.
I’m kinda done with this, we are not going to get any further in this discussion.
It sounds like you don’t know what an NFT is. A credit card isn’t a NFT because there is no private key, it’s only a public token that you hope is securely stored everywhere you put it in. You could put your credit card info on a sketchy website and they could use that exact same information for a purchase with no interaction on your part.
Same exact story with your driver’s license. And the car in Monopoly? What the fuck dude, they’re mass produced identical pieces of metal.
Maybe that’s why you think it’s so great, because you have no idea what is and isn’t an NFT.
And if you have the wrong people, you can max min the experience.
I have yet to see what technical brilliance he has beyond the ability to spend the interest gained on his billions of dollars.
You’re being proven right. You will get downvoted for these statements because a majority are just not factual.
The easiest to explain is NFTs are worthless. They have no legal validity for ownership. The largest portion of the NFT market is buying pictures, pictures which are hosted externally and can be taken down without respect to the NFT contract.
So in the majority use-case you neither have the picture stored, nor have exclusive legal ownership. So you’re buying access to a very fancy, very energy intensive, url link.
That’s not even getting into the politically charged arguments. The whole reason we have child labor laws, minimum wage, and OSHA requirements is because raw, unchecked capitalism was terrible for 99% of people.
It definitely is not for everyone, but if it is for you, it will be one of your favorite games.
If you do decide to play it, look up a tutorial series on YouTube. Mike Aben is my favorite one.
