Keeping Warm

One of the main energy loss areas in a house - windows. The concept idea is to create a revolving system that will prevent direct contact between inside and outside, so the heat is unable to travel freely. The design should consist of a revolving window with air pockets that lock the air preventing the cooling of the house. Only certain amount of air, which fits in a pocket, should be transferred at a steady rate, so not much heat will be lost. To harvest energy from the outside, the window should serve as a turbine.
