What is the science behind bathroom doors like this?

>> No.9563546

I looks like a polarizing filter sanwiched between some glass panels, when you turn the lock it shifts the panel which makes the glass opaque

LCD

When the lock is engaged, a current is run through the glass. Which causes elements within the panels to change their alignment.

So if there is a power outage, what keeps them opaque?
I imagine that indoors it would be less of an issue, as there is less natural light around, but depending where it is utilized what would stop you becoming visible as you are taking a shit (obviously it being in the reverse, current flowing to keep it transparent, cut and it goes opaque).

it's really dumb as people don't know this will happen so will not use them

if it is LCD, you just need the front and back polarizing film to be the same angle
it would make opaque the "default" state, and only let light through when powered

>people are dumb and assume they'll have no privacy as they shit
I think it would be more the state of the bathroom being visible as the person leaves.
People are dicks. They'll make a mess when given half a chance.

Indecent exposure laws generally require some form of intent, accidental exposure isn't prosecuted

Both can be. One's mechanical (less likely) the other electronic (like an LCD calculator display).

Your failed attempt in court to excuse your exhibitionism as accidental does not mean accidental exposure is prosecuted.

Dispersed liquid crystals.

Molecules float in a disarrayed manner hence you can see through it. Apply a voltage and all the molecules align forming crystalline domains which refract light, hence white opaque. If you lost power you would slowly lose order and would become clear again.

I worked on analogs of this in gradschool. High tech green buildings like to use it but it's hilariously wasteful interns of power.

You are allowed to be as naked in your own home as you want.
Technically the people looking at you in a public restroom are "peeping toms" and CAN be prosecuted.
