If I think about VR, I didn't thought 'i want to stare at a display ' I thought 'i can move around in a world without limits which includes motion, touch, perhaps sex, etc.
What we now have is just gimmicky.
I have a nice reality, there is no relevant upscale at all to use a virtual sub quality experience every day.
And for 3.5k you get plenty of wall color and tools and nice things to make your environment nicer
And yes I do have a projector at home for 10 years. It's easy and was cheap (700$ 10 years ago 720p)
You clearly don't know if this is your only source.
"Below 0° Fahrenheit, heat pumps can still heat your home with more than twice the efficiency of gas heating or standard electric heating (such as electric furnaces and baseboard heaters). They’ve been tested and approved as far north as the Arctic Circle, and are popular options in very cold countries like Finland and Norway."
Finland has over 60% heat pumps.
And heat pumps, just to be clear, work by generating a temp difference. The main problem is the efficiency and that drops also because there is a heating cycle needed for the air intake.
How many models did you actually research yourself?
