I never heard of these things besides arfcom. Are these really expensive coffee cups so the coffee stays warm for 8 hours if you nurse one cup that long?

IME, they actually keep coffee too hot for too long. For some, that's a good thing, but they do work well.
They're ubiquitous now. You can find them advertised on TV, knockoffs at Target and other places. They're nothing but a variation on the old vacuum sealed 'thermos' like my Nissan that's 30 years old.
The good news is is that they fit in a cup holder!
I brewed up a half gallon of iced tea Saturday and put it in my $15 ChinaMart OT 64oz. vacuum bottle and traveled across to Naples, FL and by the time we got back 7 hours later, it was still chilled.
For not a lot of cash, the Ozark Trails versions are a pretty good value, IMO.
