It's totally fine if you have a good seasoning on there. The soap thing is largely a myth. I wash mine with soap every time I use it and it's still slick as ever

Maybe need to get induction instead of radiant? Induction is much more efficient.

All space heaters operate at the same efficiency since they convert electricity to heat via resistance. You may have a small one and low electricity rates in your area to see a negligible change. Or maybe other uses went down and masked the increase from the space heater usage.

Thanks for sharing! These are indeed hard to get right and it's nice that you put your "failure" online. Thankfully the consolation prize for croissants that aren't laminated properly is delicious bread rolls, which I can say from experience.

Really exciting development for the climate change mitigation toolkit. Let's hope it's not too challenging or costly to scale up and deploy.

The recovery time, aka first hour rating, should be in the specs for the models to find one that suits your needs. There's more detailed research on them available as well if you're so inclined.

You can, but not as a heat pump so you wouldn't get all the efficiency gains and it will very often end up being more expensive to run than gas tankless in the near term.

I agree lawns are dumb but from an environmental perspective they can be net carbon sinks, which I found surprising. Though they are still bad for other environmental reasons.

Yeah, those are all good points and certainly factor in. There are objective studies about human comfort preferences used for building design. I expect OPs question is a roundabout way to ultimately ask about comfort preferences.

I do 80F during the day and 78F at night in the pacific northwest US. It usually gets cold enough at night that opening windows will cool my house to the low 70s overnight. In the winter I have it set to 68F. I use ceiling fans and appropriate clothing to stay comfortable within those parameters.

I can see how it's strange on the surface, but ultimately the carbon emissions wouldn't be there if the polluting activity was not funded. So to whom would the carbon emissions be attributed otherwise? Just the CEO?

The study's primary metric appears to include both supplier and producer emissions proportional to income and investments. What alternative do you suggest?
