Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

I mean it seems the more complex solution in deployment for sure, but its design could still have use in low heat industrial uses (sub 250°C, e.g. food prep, textile, sanitation etc.) where it is used heat -> heat rather than heat -> electricity -> heat. Maybe these replace thermal collectors eventually.
But that is not the point of this meme at all, just my thoughts.
IDK, heat pumps are basically multiplying the electricity they use.
Only with small temperature differences, the higher the difference the lower the COP.
You need a giant asterisk there. That "small temperature difference" is -40° to 120°F
I really don't get where those temperatures come from? I was referring to something like this. The higher the temperature difference between cold and warm side, to worse the COP gets. If you wanted to go from ambient to 200°C, the COP would drop lower than 1 and you'd be better off using an electric boiler.
