Automatic Windows

Most homes have programmable thermostats.  You can schedule your heat to work hard during the day and then lay off at night.  It would be great if you could integrate your inside thermostat with an outside thermostat and open close motors on your windows.  That way if the inside temperature were warm and needed to cool off the system would open a window instead of kicking on the A/C.  You could have security risks with open windows so you could set it up so only the back windows open or only second story windows open.  You would also be able to set the system to work when the outside temperature was between 65-75 degrees.  You wouldn't want your temperature to hit 72 in the winter time and then open all the windows in the house to get it back to 70.
