Heater/cooler windows

Create a window that seperates cold from hot. Make a switch so the user can switch to hot or cold. With this not only can they get fresh air but hot air or cold. The window frame will be the heater or cooler. It will bring all cold air out if the switch is on heat and it will bring in hot air from outside. The same with cooler setting. Let it be solar powered so it is good for the earth but perfect for the user. This is not only a great idea but a futuristic one.
