Jeeniouss!

So, heat pumps are more than 100% efficient, in that they move more heat than the energy needed to run them. Therefore, the neighbour should also install this system, creating a closed system that keeps both houses warm at better than 100% efficiency. I think this might solve all our energy needs, and global warming in one go. Tsk, to think the so called scientists have been trying to get fusion working when this solution is already practical.

Fantastic! The actual perpetual motion machine has finally been found. And all this time, I thought it would need magnets, which are also magical. But I guess all those motors in the heat pumps use magnets too.

I can’t wait for the Technology Connections video on this one.

This was one of the best parts of apartment living

mine sucked, hot as fuck in summer and the air conditioner was so loud you couldnt hear a regular conversation

Ground floor apartment here. Winter is hell, the storage area in the basement below us is unheated, so the apartment feels like Siberia. Summer is glorious though, nice and cool even in the middle of the most brutal heatwave.

Except for when the people below you are ancient and run the heater in the SUMMER..

25 degrees C is the perfect bedroom temperature at 2 am, isn't it?

[–] Smokeydope@lemmy.world 3 points 13 hours ago

I prefer 293.15 K for sleeping but to each their own.

Same. We live between two floors. Heat rarely is put on, because stove, fridge and dishwasher are enough to supplement what the sandwiched apartments floors already provide

We live between two floors.

I saw this in Being John Malkovich but didn't realize it was a thing in real life. So, like, you live on the 9 1/2 floor or something?

Yea for real. I live on the middle-ish levels (10-17th floors) and never use the heat. Winter time, my apartment gets heat from the lower areas and sun is hitting my windows from sun rise to sun down, so I actually have to turn on the A/C in the winter cause it’ll get to 75-78. Summer time, the sun is higher up in the sky so it doesn’t shine directly into the apartment so the A/C gets a break.

That all said, fucking Spring and Fall are a bitch cause the sun is shining directly into my eyes, so I gotta shift around during the day and I gotta adjust the A/C like every hour, cause I’m too hot or too cold

Yes I have heard of blinds. This is a rental and they installed one of those pulley system blinds (white shades) so I’d either have to ask them to swap them for darker ones (they won’t do that) or install my own blinds and pay for it out of pocket. Any more suggestions?

[–] ayyy@sh.itjust.works 2 points 8 hours ago

For a rental? Heavy curtains but those make the room dark.
