But what happens in August when there's too much heat. Do the windows cook everything that's alive inside the house or is there a way to shut em down in the summer so they don't over heat your house. Did you also test them at the end of Febuary when the outside temps are the coldest and you have the least amount of sunlight on average? Good poste though and great idea.
