> nowadays very few people have a house with a basement like that anymore It depends on where you live, and the type of ground underneath you. Where I live, everyone has a basement.

They're probably referring to an unfinished basement vs. a finished one.

An unfinished basement is still adequate for storing a freezer. Unless by "unfinished" you mean one without walls or a floor.

They are more efficient in keeping the food frozen. But they are less efficient in getting the food out of it. This is how you find 5 year old products at in the bottom of the freezer when you finally clean it up.

That's an organization problem, not a freezer problem. In my field, we go vertical on the horizontal freezer: https://lh3.googleusercontent.com/proxy/j3SL_cL0MF9c3ASG-LfR...

Unfortunately, the link doesn't work - and I was looking forward to seeing how you organize a horizontal freezer vertically because I have the 'black hole' problem...

I meant the opposite. I do indeed have a (very) unfinished basement that gets a bit wet with a freezer. Many people won't want a freezer in their downstairs living room. At least that's how I took the comment.

There is a good trick to use if you leave on vacation (or for monitoring breast milk for those new parents). You can freeze a cup of water, and throw a coin on top. If your freezer melts at any point, the coin will be at the bottom, not the top of the water glass when it refreezes.

Ice floats. Even if the most of the ice in the cup has melted, but there was a little bit of it left, the coin will stay on top. From my personal experience: while we were away on vacation, there was a power outrage for 24_ hours. Coin was on top, but all ice cream and frozen packaged food was ruined. Not sure about big chunks of beef.

I left the comment partially to see if anyone countered it.

I wonder if the better solution would be to tip it on a 45 degree angle. If it melts, it will now be flat with gravity. No coin required

I was just looking at getting a NG generator installed for my parents on the east coast, after watching these recent storms come through. I'd dawdled on this for years, because it was just infrequent enough. Anyway, I also looked at battery backup systems (Tesla, Enphase, etc). Unfortunately, it seems they haven't reached cost competitiveness with the plain old gas generator yet. Not a lot of power density (time), an…

An inverter that runs off the 12V battery in your car is very cheap. Get one, and an extension cord, and you have an emergency power source to cool down your freezer every few days.

Years ago, I installed a Tripp Lite inverter/charger along with two 120AH deep cycle marine batteries - all sitting on top of my fridge. I calculated that I can get a few days of power. Also have another 1500w inverter for emergencies. And I always ensure vehicles are complete full before any large storms. Losing all your cold food is expensive!

My basement is 80% finished, but the freezer lives in the unfinished part. But "unfinished" is relative, I still have concrete floors and walls with insulation on the walls, just no sheetrock and bare rafters on the ceiling.

> 27 hours in a garage and not a basement

thats not a quote...

Well, it's a paraphrase:

> If it were in a hot garage at 30° C, the food would thaw in about 3/4 of the time.

How do you safely handle dry ice? I'm legitimately asking, I know retailers sell it with big warning labels but I wouldn't know how to transport it, move it, and similar.

Other people are giving good advice, but you should also know that it isn't that dangerous. People have died from the fumes, but only when they have a lot of dry ice in an enclosed area (e.g. a car). It can cause explosions, but that's mostly from people going out of their way to build bombs. It can cause burns, but not instantly and the pain will warn you before you get seriously injured. Don't be particularly afrai…

If it were really dangerous, you wouldn't be able to buy scads of it at a grocery store.

Also, whole burying fish may be logically obvious in this case, it is almost never the correct move in any other situation. Actions that defy common sense can be really difficult to commit, particularly in times when the stakes seem high. What if they buried it, the world was ending, and they somehow needed all that food? It's an easier call to make here than it was there.

Can you imagine that conversation with your neighbors? "Tom, why are you burying fish in your yard? Don't you have better things to be doing like evacuating or collecting fire wood right now?"

"Nah, if I don't do this, my fridge might smell terrible in a week."

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.

Well, you're not driving off the "black bits". There's still plenty of "black bits" (unburned carbon and high-carbon compounds) in the interior. It's just that 1. you really really want to wait until the lighter fluid is burned off and 2. the whole surface hasn't started burning until the whole surface has started generating white ash. In the case of charcoal with igniter integrated in the outer layer ("match light" charcoal), I would guess you want to burn off that outer igniter layer.

As a young boy scout of 12 or so, I ate some pork that my patrol and I had cooked over charcoal before all of the lighter fluid had burned off. It tasted like lighter fluid smells. We never made that mistake again.

Pro tip from 12 year-old me: styrofoam cooler lids make great fans to speed the progression of the reaction.

Pro tip 2 from 12 year-old me: don't get the lid too close to the charcoal, or it will melt. Also, wet wool finger mittens can cook and become brittle far from a wet wood fire, because the fire gets very hot when you blow on it to keep it from going out and very cool when you go to check the temperature near your mittens.
