modern day ice cream churn?
I bet these guys never heard of a swamp cooler either
I made a ghetto 5gal bucket evap cooler and dumped
Salt on the ice long long ago
Why bother? If it works, once it’s mass produced, it’ll become the new evil…
ethylene carbonate:toxic and hazardous:

converts to ethylene glycol if consumed, which is EXTREMELY toxic to kidneys even in very small amounts ...
“Though technically, the salt does not melt the ice, its dark color attracts heat, allowing the ice below it to melt, which than allows the salt to mix with the water. And it does not refreeze because the salt dramatically lowers the freezing point of the water.”
Maybe someone can help me. So I can bite that ice can only lower the freezing point of liquid water and not already frozen water, but how does salt have a “dark color” that is so dark, it attracts heat, over the whiteness of ice and snow? I see salt as white to clear, so what is going on?
sodium iodide (NaI) salt
ethylene carbonate
Isn’t this this similar premise for a DC battery that is using the difference in chemical potential and then returning it with electro-mechanical energy?
bkmk
So, then...
...my next fridge will work half as well as the last one (which worked half as well as that preceding it)?

I’m a big fan of hydrofluorocarbons.
They’ve made my life better in so many ways.
Hopefully I’ve stockpiled enough to last the balance of my life.

Environmetally friendly? Perhaps. But it still uses electricity which will be increasingly in short supply as more coal plants get shut down. Under the currenr regime, this tech is a non-starter.
Lawrence Berkely National Laboratory salt comes from San Fraqncisco where everything is covered with dark filth.
What’s wrong with ammonia cycle? Be kinda nice to be able to run your fridge from a propane tank or direct solar when the AC power goes off.
This technology is just around the corner .... how far is the corner?
How does cost compare? Put it on the market without government subsidies ans see how it goes.
They’re using propane/butane now. Works great as a refrigerant and the chance of it causing an explosion/fire is next to nothing, due to the small quantities and fact that leaks are very rare.
So no need for anything ‘new’, unless fossil fuel use in refrigerators will also be outlawed, even in a closed system - and don’t laugh.
Eh, Einstein thought of one first (I think Bose might’ve contributed) ?
And Electrolux is holding the patent, last I heard.
