MIT has come up with a new idea that tracts where you are standing and blows cool air onto you; this idea is called "Cloud Cast".  Cloud Cast is made up of a collection of aluminum rods that are attached to the sealing; the cool air comes out of the rods. There is also a detector that targets where people are standing and slowly lets out the air. The cloud cast is not an ordinary air-conditioning system, it is energy saving and much faster. The inventors are saying it may take years for it to be approved and get into peoples houses.
