Taking the current fad for heat pumps one step further, is there a reason we couldn't have other appliances hooked into circuits of cold/hot/return pipes carrying a refrigerant or coolant throughout the house? For example, your refrigerator or water heater would be just a passive heat exchanger with a thermostat to open and close a valve when necessary.

In the case of a refrigerator, this would mean that in summer, the heat gets pumped to the water heater or directly outdoors, rather than getting pumped into your kitchen by the refrigerator and then pumped outdoors by the A/C. And in winter, the waste heat gets pumped into your HVAC to heat the whole house and not just the kitchen.

In the case of the water heater, this would mean that in summer, you're scavenging heat into your water that would be dumped outdoors by a traditional A/C. In winter, you'd be sucking heat in from the outdoors and from your fridge, and only having to run a heating element to make up the difference when necessary.

Diagrams to illustrate are mine. Yes I know the heat exchangers would be counter-current, but I tried to draw them as simply as possible.

Can anyone this piece of I came across today? It's a bulb suspended in a cylinder, with a serpentine tube connecting the bulb to an orifice in the side of the cylinder. The bulb also has an orifice at its tip, and the cylinder is open at both ends.

Every day @users posts some reports similar to this one - here are some annotations to help you understand why they have the shape they do.

Hey @dragfyre, for some reason, I only see a small subset of @bahai's and @bahai_wiki's posts from my account, but many more (I presume all of them) when I visit the page directly in a browser. The problem seems to have started around 4 March 2020. Do you have any idea what might be happening here?
