You’d suffocate, so it’s moot.
You know not everyone is just using it for the fridge.
That’s so people can keep their fridges cold. They specifically warn people NOT to use it to cool their apartments.
Probably not? You need more energy for every degree you cool something. So you want to minimize the temperature you have to go under your desired temp.
Unless you get enough economy of scale by making all the dry ice in a central location. But then you have to ship it everywhere. My guess would be not worth it.
You could use solid nitrogen if you want to avoid asphyxiating.
Also, it takes a lot of dry ice to keep a fridge cold. Like, 10lbs/day for a regular fridge.
Even funnier, it will carbonate things in your fridge. Water, milk, even fruit… It’s super fucking annoying to keep a fridge cold with dry ice for more than a day.
Oh, that 10lbs/day assumes you give up on the freezer.
The freezer needs 20+lbs a day. In addition to the fridge’s 10 lbs
Last I read anything about it I think the most efficient way to cool a building is with a combination dehumidifier and more traditional AC unit, ideally using the waste heat from the AC to drive the drying from the dehumidifying stage. Lowering the humidity lowers the thermal mass the AC has to deal with if I understand it correctly.
Pretty sure that’s what big buildings are doing already.
Again, this is a problem with capitalism. Consider my building. 12 apartments in total. it would almost definitely be more efficient to cool them all with one centralized system, but because they want to bill each tenant for electricity individually, we all have our own units.
Same logic goes even bigger than that. It would probably be more efficient to have one central cooling system for all the buildings on the block. But because each landlord has to pay separately, and responsibility is determined by the concept of private property ownership, they can’t do that either.
Only with socialism could the most efficient solution be employed.
The reason these apartment buildings all use per-unit is more complicated than that. They don’t want all the apartments sharing common ducts. That’s a recipe for smells/sounds and issues between residents. It also makes zone-controlling more difficult if you use a normal fully ducted system. Fully ducted systems are designed for offices or single-family homes primarily.
The real efficiency gain is in using swamp coolers. But those are useless if the humidity is high. You could have a hybrid system that uses the swamp as much as it can, and switches to conventional AC when needed, but that would greatly increase the cost and for a small building probably never recoup its energy usage.
But if the whole block/neighborhood teamed up for one such system…
You can, of course, read all about this on Wikipedia.
AC:
Swamp Cooling:
Humidity is a big driver of the perception of it being hot though, so even if a swamp cooler will work there are situations where it’s not ideal. The summer humidity is by far the worst part of living in NC:

We just got an evaporation cooler last week and it’s awesome. Berlin isn’t humid enough to make it a bad choice.

Humidity index?
Percentage of days where the weather feels like that subjective descriptor?
Yeah, it’s kinda bad but it was the first thing I could find. I wish they left off the arbitrary descriptions in favor of some numbers, but basically percentage chance that a given day will have a certain dewpoint, which is a more direct measurement of actual moisture in the air vs humidity which changes with temperature.
I see a lot of radicals on Twitter advocating for abolition of wage labor. How would people who work for organizations that don’t make money (fire departments, public school teachers, any number of 501( c )3 workers) make a living under this system short of outright communism?

Some possible outcomes:
- Everyone becomes a contract worker instead, thus not technically being wage laborers.
- We develop better incentive systems so that these organizations can be run in a way that mirrors the usual for-profit sector, i.e. they get paid in a way that is commensurate to their net social good rather than narrow private good.
- They become cooperatives that effectively distribute government grants to their members. Obviously vulnerable to corruption, but then it’s not like the current system isn’t.
