Old and busted: Old curtains that actually block out more visible light allowing you to actually darken a room and not worry about urban light pollution
New Hotness: another LCD based solution, this time in an add-on film that needs to be wired up.

Curtains, cheap.

/WiFi enabled digital shade, not so much

But it has an "app"!  That automatically makes it cool and trendy.

I am most curious about the infrared reflection part of the equation.
I also like the glare reduction/translucent part of the product.

I have large, south and west facing windows in my living room.
It would be nice to get the light without the heat. Blinds can do only so much.

so this product would solve the infrared problem winter and summer.

and now I am wondering if I need anything at all, given that the cool factor is gone

dammit, logic, what are you doing to me??!!

I haven't read the article yet... but you make it sound like those LCD windows that work like a calculator display with out the reflective backing and without digits... apply voltage and all the liquid crystals realign to from transparent to opaque.

in which case... yes.. those have been around for years, just not widely implemented... in fact, I can't say I have ever seen one in the wild.
have they stopped trying to sell the whole windows and now are just selling the magic film?

okay... just read the article... and that is exactly what it is.. .and most modern windows and window film block UV as it is... applying the voltage will make no difference in that function.

An app!?! now... are they wifi enabled... or do they use something like the data over mains X-10 like stuff?

I would personally go with one wifi control node then a bunch of little wifi enabled windows...

Fark that.

I want smart paint for my roof, so it reflects/absorbs/radiates as appropriate for the season and the time of day.

I want photovoltic paint.  So my roof is a solar panel.

1m square sheet of this stuff is $250. Curtains are about $40. Hope you have small windows or lots of money.

This is not new. Films like this have been around for many years, and networked home automation systems even longer. I had a window with such a film inside installed a couple of years ago in my kitchen, and it is hooked into my home automation system just like my lights are since it is controlled by a regular light switch. I have an interesting looking house that seems to be on some walking tour so I'd have people walking up to my kitchen window and staring in all too often. Now with the smart window and the security camera I have covering the outside things are set up to make the window go opaque when someone walks up to it.

Yeah, that's neat. But what I really want are windows that also are PV panels.

Where are my solar-power generating windows? I was promised flying cars solar power windows! (dreams updated for new reality)

There are a few companies that make similar films. Glassapps and Prodisplay are the two I can recall off the top of my head from when I was shopping around for my window.

The only place I would ever put those into any design is somewhere that curtains are not practical.  Otherwise, my professional advice is to use curtains.

Curtains? Just nail some sheets over there top of the window.
 
2013-06-08 08:30:51 PM
When there is no electric current applied to the film, the suspended particles are arranged randomly and absorb light.
This makes the glass panel look dark, or opaque


Is it possible to engineer it the opposite way, so that the current produces the opacity? In the event of a  power outage I think I'd want to be able to let more light in from outside, not less.

Sheets? What are you, rich? Ain't you got any tin foil scraps saved up?

We're not *that* futuristic yet for automatic window dimming. We don't deserve it yet.

Well, what if the power goes out while you're in flagrante delicto?

I vaguely remember this sort of thing being demonstrated at a World Expo back in the 1950s or 1960s.  At the time, liquid crystal panels were bulky and expensive so the windows were too heavy and expensive to be practical.

/me wants affordable photovoltaic roof shingles, dammit...

Whoever wrote this article apparently has no idea what the word "opaque" means.  The film doesn't appear to block out any light, it just frosts over.

tape and aluminum foil. Sheets and curtains smell musty when the sun hits them.

Only poor people use cheap curtains.

Do you think anyone cares what they want?  We already gave them sausage on a stick, isn't that enough?

windows that change opacity by one means or another are nothing new, pretty nifty tech really

It's great until your bathroom window controller crashes and goes transparent while you're dropping a grunter.  Or the neighbor kid hacks your daughter's bedroom window.

And this story reminds me of a friend's house from way back.  The bathroom had a clear, wall-to-wall, floor-to-ceiling window that had a wooden "box" grate maybe a foot or so in front of the window on the outside.  Looking from more than about 20' away from the outside, the view was pretty well obscured and, even from the deck, you couldn't see in during the day.  Wasn't an issue until we started playing out on the deck during warm summer nights.  One of the guys was wandering and smoking a cigarette and said, "Oh, shiat!"  Moved a lounge chair to block off part of the deck and said something like, "Let's just stay on this side of the chair after dark."

Some trains in Japan that go near buildings at window height have had these for at least 20 years. They fog em up near the building and then make them transparent again.

Maybe I'm missing something, but how can a system that requires electricity be energy-saving when compared to shades, which require no electricity at all?

Emposter: Maybe I'm missing something, but how can a system that requires electricity be energy-saving when compared to shades, which require no electricity at all?


They only draw power when transparent, and the power draw when they are on is minimal. The one I have uses .65w/sqft. The power savings come from the fact they reflect heat much better than curtains when off.

The home automation aspect helps save power because you set the system to turn off the window when heat and/or luminance is high (which is also possible with curtains, so that is not unique to this technology).
