Will they make beer goggles out of this?

But can they withstand a mostly peaceful protestor throwing a 5 pound brick at it?

So! Windows will be translucent during the day when we want to see out of them and transparent at night when we don’t necessarily want to see out of them. To me that seems a bit goofy.

So, it gets hot, you can not see out of it. Thus reducing the desire to go outside on a sunny day and when it is cold and miserable out there you will see it clearly.

Did Catbert design this window?

They have it backwards.

We need glasses that are transparent when we are looking at someone hot.

And blurry when we are looking at someone not.

[Bob434]

can it be called a window when you can’t see through it?

Any automotive use will suck in summertime. Or will you swap out windshields like you swap out winter tires?

I can see home builders using these windows as panels, such as a horizontal transom at the top of the window where the sun's rays are strong, but leaving the bottom half or two-thirds as conventional double- or triple-glazed insulated windows. They could also be side panels the height of the opening on either side of a clear-glass sash window.

They would be more useful in settings where looking outside is distracting, such as office settings.

I got some gray window tinting film and applied it to my most exposed windows in rarely-used rooms, like the office room and the spare bedroom. It is a peel-and-stick product. Works well to keep the price down, but it's not particularly pretty. But it's behind blinds, so no problem. You can still see through it from the inside, but it also tends to obscurre the view of people looking towards our window.

This is a workman, not me:

I have an idea ... make it generate electricity at the same time

Glass window panes have always been liquid.

Glass is a super cooled liquid.
