Uhh, if your basement frequently gets below 0 °C, you have far bigger problems than the freezer. This should normally not happen unless you're living somewhere in the Arctic.

I have a dedicated garage with basement that is detached from home. I still have to see what temp there is in winter.

Unless you're in deep Canada, any basement should always be deep enough stay above the frost line: https://en.wikipedia.org/wiki/Frost_line

It may be OK after the smoke clears. Rookies who have never used a real charcoal BBQ don't know when the coals are ready and start cooking too soon. You cook when it seems like it's too late the coals are ash but that's the time to do it.

So when the coals are pure white, that's when to start cooking?

White & glowing. You're trying to drive off all the black bits.

Maker of the video here. For a moment, I though this was about my video and article, but reading the comments, it's more about everyone sharing their stories. Few of the comments reflect having read the article. Fair enough, sometimes it just takes a link to give theme for a discussion.

I am a fan of your site and appreciate your thoughtful writing, but I found that I could not get very far through this article on mobile (and I usually read HN on mobile, not desktop). The problem is the layout. The font is small, and if you zoom in, it does not wrap.

I have noticed this is the past, it's not the first time that one of your articles has been linked on Hacker News. And I always thought it was strange, because you appear to use very minimal CSS styling, that word-wrapping would not work properly "out of the box".

Looking at this page now (on my laptop) I see that everything is inside of a fixed width (1150px) table, so that explains it.

Have you thought about changing your pages to use a more mobile-friendly setup, like a flexbox layout?

I imagine now that you have hundreds of pages and years of content under your belt (quite an impressive site!) it might be difficult to make such a change on all of your content!

The solution for this is to buy a generator. Hand started 1 kW ones go for ~130€ these days (https://toom.de/p/inverter-strom-generator-sg-1200/1501059), plus enough cable from to . That's enough for 24/7 running the fridge and any other important appliances (think a TV/radio and a cellphone charger to have access to some form of information/communication).

Don't even need to keep a jerrycan around and risk the fuel go stale if you know how to siphon fuel from your car in an emergency (for a widespread outage, it is not guaranteed that gas stations are operational). Only requirement is to check oil level and start them up and run for at least half an hour once a quarter (you might get away with half a year).

PSA: Do not, never ever, even dream about putting that generator indoors unless you have a certified chimney sweep (or whatever your regional equivalent is) certify the safety of the exhaust system. And even if you do (or have any other sort of fuel furnace in the house), get at least a CO warner at the most bottom place of your house!

Hi. Actualexperience here... it depends on the ambient temperature and how much stuff is in said freezer. So heres a data point: Freezer: normal upper level refrigerator freezer chock full of frozen fish caught on holiday in Alaska. Place, Time: Houston, TX, Late Summer, Hurricane Igor just hit and knocked our power out for 14 days. Findings: We kept the freezer shut and at about 4-5 days the fish was noticeably thaw…

PSA: I've worked disaster relief/reconstruction in Houston, New Orleans, and a few other places. If you come across a fridge with the doors taped shut DO NOT OPEN IT. If you come home after power was lost for more than a day or so, TAPE THE DOORS OF YOUR FRIDGE SHUT AND DO NOT OPEN IT. It's not worth it. You will never make the fridge use-able again. If you have to leave ahead of a disaster, consider emptying your fr…

> If you come home after power was lost for more than a day or so, TAPE THE DOORS OF YOUR FRIDGE SHUT AND DO NOT OPEN IT. It's not worth it. You will never make the fridge use-able again.

I don't quite understand what you're saying here - that after 24 hours, things will be defrosted and rotted enough that the fridge/freezer will stink forever? That it should be taped closed and the whole thing disposed of after the event? Or are you saying only if you open it, it'll never be useable again? I have experienced a number of multi-day power outages, and have never had to tape a fridge shut and not use it again, so I disagree pretty strongly with that advice.

Absolutely agree with preemptively emptying fridges/freezers and leaving doors propped open.

This is why you will see freezers lining the street for trash collection after a major power outage during a hurricane. Freezers are not super-expensive, and you can usually get them covered by insurance or disaster relief, so it's easier to just duct tape the entire fish coffin and be done with it.

You missed the perhaps most important datapoint: how often and many times did you open the freezer? Side loaded freezer and fridges are extremely inefficient because all the cold air is let out when you open the door.

This is also why it's important to FILL the freezer as much as possible if you know you might lose power. We lost power for 4 days, but I packed in every water bottle I could find before hand, and everything remained frozen for the entire period. Literally almost no space left for air. We also did not open it, of course.

Plastic bags of water are even better because they leave no spaces between them.

I used gas for 20 years, then induction for 10. Induction wins everywhere (reproducibility of heat, speed to heat, ease of cleaning...) The only thing I miss a tiny bit from gas is the ability to tilt a pan to have oil gather in a puddle to deep fry something small. Other than that everytime I use gas I long for induction.

Induction sucks at making you have reasonable utility bills though.

I don't know. I pay I do not remember paying much less before induction, but I do not remember.

This is not a big issue for me, though

How hot was it when this happened? Were you there to manage the situation or did you have to leave?

If you have to leave in a hurry and are not able to empty your fridge, and it is hot, and you are not able to return for a few days, then yes, your fridge will probably never be usable again.

If your fridge is in a cool basement, then yea, you probably just have some food spoilage.

I keep a bag of ice cubes in the freezer for this purpose. If it’s a single cube the freezer went out.

It's a good trick, although there's a caveat: it only works with freezers that aren't self-defrosting.

If freezers self-defrost by lowering the internal temperature, won't that spoil the food inside by lowering and raising the temp multiple times?
