Far down you have chains and axles and ropes

Sometimes even solar is about boiling water

Unless the person/entity has a history of bad behavior, which Facebook does

Not a bad look IMHO, but yeah Ferraris tend to be distinct and this isn't really

We use less energy for cooling in the summer than for heating in the winter, and it gets worse because the latter is generally less efficient because that does NOT usually use heat pumps, considering heat pumps are more efficient than just heating with electricity directly (it moves more heat energy than you put in electric energy).

So once you have heat pumps capable of heating installed and ready, to make winter heating more efficient, then it's trivial to flip some valves to let them cool, so what dumbass would then refuse to use them in the summer when it uses less energy?

If you're still concerned about the energy use, then install heat capture tech - because both the energy spent and the energy moved becomes heat on the hot side of the pump, you can just extract that heat and store it in for example water for later use, and now the fraction of energy spent on top what you were already going to use is much smaller still.

And that's assuming you weren't already powering it with solar.

Yes, you can even confirm the published source reproduce this specific apk

Signal can be installed from an apk from their site

They spent years lying about their encryption algorithms too acting like they're more secure than Signal when they never were

RCS on Android defaults to E2E encryption now since some year back, and Signal has been around for a long time now
