there was a question posted on the IML that i was interested in and when i
asked i got no reply... maybe no one saw it, oh well. anyway here it is,
someone ask about Scott Buwalda's 200 SX and his glass the stuff that goes
from clear to opaque (and the other way) when you apply voltage.... i was
wondering (a) what this is called , and , (b) where i can possibly still
get some... this is some interesting stuff i'm trying to find it now, lol..

You might try on alt.sci.physics or one of those. It was probably some other
technology adapted to car audio that they might be able to help you with it.

I've seen it used in architectural applications. There's a bar in
Manhattan's soho that was famous for its toilet doors (really).

In any case, poke around on the web and you'll eventually find it.
It's quite pricey and I doubt you can get it in anything but a flat
pane.

As a student of architecture, one of my design projects had me doing some
research on different solar control technologies with glass. What you and
the original poster are referring to is called electrochromic glass.
There are a few different ways to go about it, some more electrically
efficient than others, but that really is of interest to architects and not
audiophiles. Here's a simple link that'll get anyone interested in the
subject's feet wet:

Hope this helps!

Well, there are different types in development... one of them needs a
constant voltage applied in order to keep the tint in effect, whereas
another
is an actual state change in the crystals that does not require a constant
voltage. IIRC, the latter requires more voltage in order to do the change,
but doesn't need constant power, while the other draws a small amount
continuously.

And next thing you know is that there's going to be kids bumping around
with windows tinting and untinting because they can't keep their voltage
up and stable with a poorly designed power system in their vehicles.

YEP!!! you'd be surpised how many hood rats pull up in there honda's and
toyota's at my shop and they think they actually did a good job on the
system becuase there headlights are dimming when the bass hits......

NEWS FLASH: THAT WAL-MART AMP AND CAP AINT DOING ****E!

true... plus you could pre-tint these windows so they are legal tint when
you're driving.

hehe... it would be a good way to secure the car a little more. Untinted
when driving and black tint when not driving, means people can't look in
ya
car and think "ooo, i might steal that stereo"... they might think twice
and
decide it's not worth breaking in if nothing good is gonna be in there

Just like KITT in Knight Rider! lol. I think they do make auto versions
of it, but you're right, it ain't gonna be cheap.

I wonder if this could be done... i'm tipping electrochromic glass isn't
cheap. And can you get tempered glass versions of it?

i wish i knew of a place in the US! lol

hehe... yeah!

anyone know a place in Australia that sells it? i had a look on the net
but
the links all seem to point to australian sites that explain it rather
than
sell it.

The links on that page provided earlier in this thread mentioned it for
auto use, but most of the links were broken.
