Liquid crystals need current and complex polarization to work, and I really want to keep the window simple in design. I guess I never really thought about how hard the liquid choice would be, but this is actually turning into quite a challenge. So to once again add onto the long list of characteristics this liquid must have, no it can not freeze in the winter.
For those who feel like reading and want to hear my whole story:
I guess Ill go ahead and divulge my entire pipe dream idea for an easily marketable "smart" window. Im currently working as a residential appraiser while still attending college, and I noticed that in many homes it would be really nice to have a window that you could change the opacity to, without hampering some of the great views. In theory it would be an adjustable window tint that could block light like a blind, but still be easy to see through. I started thinking that LCD technology applied to an entire window would be perfect, as Ive seen the technology used perfectly in welders masks. In my search for information on how to do this I found that one company already makes glass containing liquid crystals and has dubbed the windows "privacy" glass because of its ability to go from completly clear to a frosty white non see through look. Well, this wasnt the use I was looking for in my application, so I continued looking. This is when I came accross the electrochromic "smart" windows, and found that this nearly finished technology worked exactly how I invisioned and even more by actually using a tinting film that can be manipulated by electricity. However, its now almost 6 months after the companys have rolled the electrochromic windows out to consumers and only a handful of companys can actually afford to use it. The technology is currently too expensive and complicated to implement, and therefore I see a need for simplification. I believe that a simple dark liquid solution sandwiched between an already existing two pane window structure may be the realistic solution that the mass market needs. This would only require a simple handcrank, at the cheapest end of the structure, in order to work. Now I realize that acutally marketing an idea and getting it out there is usually nothing but a pipe dream, but I figure I might at least see if this one is possible. So what do you guys think?
