Heat pumps harvest ambient heat in outdoor air and move it indoors separate from ever needing to combust fuel or power heating coils.
Some of the changes in motorcar technology are impressive. They have engines that turn off whenever your motorcar is idle, and then they start back up the minute you let go of the break. They’re meant to aid in gas mileage, especially on mid sized cars prefer crossovers which aren’t as inherently efficient as sedans. I have driven these cars a handful of times when I needed to rent a car while I was in my travels, but I’m not much of a fan. I don’t prefer the delay between the moment you hit the gas and the point at which the engine starts and the wheels start to turn. When you’re used to immediate acceleration, it can be a tiny bit of an annoyance. I’d much rather have a hybrid car with an engine that can run absolutely on electricity with gas as a backup fuel source. These are easily the cheapest cars to drive on the road, assuming you live in an part with charging stations for electric cars near your home and task. As excited as I am about these advances in motorcar technology, right now I’m fascinated more by modern Heating and Air Conditioning components prefer my low temperature heat pump. Heat pumps harvest ambient heat in outdoor air and move it indoors separate from ever needing to combust fuel or power heating coils. Since there is always potential energy in outdoor air as long as you don’t reach absolute zero, you can easily move that energy indoors by reversing the refrigeration cycle on a familiar cooling system. Imagine having the boiling condenser equipment indoors while running an evaporator coil in ambient air while I was in a cold snap. The coolant coming indoors will be boiling and you can heat your house with the warmth coming off the boiling compressor.
