Much easier than trying to get and find dry ice in an emergency.

My favorite use is sparkling grapes. https://sciencenotes.org/how-to-make-fizzy-fruit-with-dry-ic...

Put (food grade) dry ice at the bottom of a bowl, then a clean cloth or towel (for insulation), then grapes. Ideally our a loose fitting cover over the bowl.

As the dry ice sublimates, it passes through the grapes which will capture some of the CO2 and carbonate the grapes.

Very fun, and much less practical, use of dry ice…

I get it all the time for camping trips

I have a 1kW power station with solar charging, which won't fare a whole lot better; it'll run a fridge for maybe 2-3 days if it's sunny outside.

Low-tech solutions win in power outages of more than a day or two.

Power outages typically aren't more than one day, and dry ice is not going to help you for those outages.

I don't have any dry ice suppliers nearby (no the Walmart doesn't stock it), it's not a low-tech solution.

The low tech solution would be a bigger gas canister. 2 gallons a day is not bad at all.

In an apartment building or something I can certain see the use case for dry ice though.

But for those who like protein packed meals in a comfortable environment an additional deep freezer is a great investment.

You can deep freeze extra veggies/fruit if you have a beef with meat.

A dehydrator is another good option for preserving perishables. The shelf life is a bit shorter than most people would think, but properly packed and sealed you can get at least 3 months or so.

A freeze drier will preserve perishables for significantly longer than a dehydrator, but they cost an order of magnitude more. If you have a big garden or something though the three grand outlay might be worth it.

1. The human body can synthesize protein except for a few amino acids. These are called "essential" amino acids because we must get them from food.

2. Protein "quality" refers to the ratio of essential amino acids, specifically how close they are to the ratio of essential amino acids in our bodies. This metric is used to gauge the rate of absorption of proteins, not the overall amount of absorption.

3. Red meat is not ideal protein quality. Whey protein is actually a lot better because it consists of amino acids in ratios that are better for absorption. Also better than red meat is... rice and beans.

But honestly I think you have some kind of vegetarian agenda, and that's causing you to use some pretty tortuous reasoning to reach your desired conclusions.

I also love beef, tuna, shrimp and many other meats.

I like having a variety in my diet and to eat what I prefer.

See how quickly you hate beans and rice if you only have beans and rice.

Navy beans on Instacart are currently $1.14 for 104 grams of protein. https://www.instacart.com/store/items/item_1807377332

Ground beef on Instacart is $5.23 for 76 grams of protein. https://www.instacart.com/store/items/item_1785250798

Beans have 91 grams of protein per dollar compared to ground beef's 14 grams.

And you're comparing price per protein? Wouldn't this thread be based on amount as we're talking about storing it?

Also, see my response about "protein quality". https://news.ycombinator.com/item?id=32417603

But either way I recommend storing and buying both. Definitely not going on a crusade against beans, they're great! (and so is meat)

Another user recommended eggs if you're concerned about protein to price ratio, but it's harder to store efficiently without getting creative.

You could farm your own eggs as I do, but it requires a lot of space (and a love for chickens, they can be a hassle).
