I can see it working for glass houses that need to occasionally need a TV (think really rich people with overzealous architects). The cooking problem is situational and not always an issue for every window.
I would instead love E-shades to be a thing instead, I'm still waiting to press a button to make my windows go dark.
I’ve only seen samples for sale, and any sort of large scale installation is “contact us, we might have something.” I’ll just stick with Lutron until suppliers get their act together.
Then you'd have ZERO natural lighting in your house. Far more realistic is using them in lieu of traditional "paintings" though outside of Samsung Frame - most of them have poor viewing angles and are glossy which destroys the illusion.
