The hunt for the most efficient heat pump in the world

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Where? My $300 U shaped window AC is modern quiet, tidy and efficient, but I was reading about window heat pumps being $2-3k.
My wall mounted split systems were <$1000 AUD each, 3.5kw. Found a sparkie and a fridgie to do the install, set us back around $3000 for two systems installed.
Great units, added some wifi dongles and tied them into my home-assistant for remote / out of home control & scheduling.
Probably the best addition to our home currently, don't know how we lived here using pedestal fans and gas heating.
Search Amazon for "window heat pump".
I cannot comment on quality or efficiency.
Well all conventional air conditioners are strictly heat pumps, but when we say heat pump everyone usually means bi-directional heat pumps - ones that can provide heating as well as cooling. My Amazon results are not that and I was recently reading about them coming to market starting at $2k.
This one is $449 and clearly states several times it can heat with a heat pump.
Maybe it is full of shit. I cannot say.
