Wonder if the 2.5V control range is on top of some higher voltage bias. Also, wonder what the current requirement is to keep the glass heat/light opaque. If it's a straight 2.5V control range and the current is low you could picture active windows and skylights with an embedded photodiode feeding a microcontroller that adjusts the transparency of the glass based on the incoming solar strength. The control could be fed by NiMH or Lithium rechargeables that were trickle charged by a solar cell in the frame with the charger IC also run by the micro so the whole thing was self contained. That would be an inexpensive circuit to proto using an Arduino board for the micro and ADC -- and with a Bluetooth shield you could make it remote contol with an Android app. I'd buy a set for my family room.
