There is nothing really special about radiation itself in Hawking radiation. Is is just photons like other forms of electromagnetic radiation. It is only unique in the way it is produced at the event horizon of a black hole. It arises from the steady conversion of quantum vacuum fluctuations into pairs of particles, one of which escaping at infinity while the other is trapped inside the black hole horizon.

This lower temperature system would "stay cool longer" because it is colder.

No, it will not. It will absorb environmental heat faster due the higher temperature differential to ambient. The larger temperature difference between the ice-water mixture and the ambient temperature will cause the mixture to absorb heat faster, thus speeding up the warming process.

It can be confidently incorrect. It does appear to get slowly better. I asked it last week what some good stating words would be for WORDLE. It gave me about 5 paragraphs describing Scrabble including letter scores and bonus squares but no list of starting words. I just now asked it the same thing and it gave a shorter description of WORDLE that was correct but then provided a list of words that ranged from 3 to 8 letters long.

The adoption hesitation you have will not affect people that have places to charge now. The credit combined with the realization that gas can hit $7 a gallon or even more at any time will certainly have meaningful impact. People will go looking for EV's and even if the model does not get the rebate, other models will have their prices lowered in response to it.

There is new research that shows wearing a mask outside during cold may protect the wearer from respiratory viruses since very cold air reduces the effectiveness of the nasal passages immune protection significantly.
