The concept was made by Greg Beck, a dude from Ohio, as some sort of a "hey, wouldn't it be nice if..." thing. Or maybe as part of his showreel as a product designer.
Sadly, his website[0] is down, but you can find a version without images in the archive[1].
The domain name is still registered though. You could write him an email and ask what happened. ;)

Just because something is in an After Effects mockup doesn't mean it's practical to engineer.
I suspect the heater grid might be tricky or expensive, though.
