Abstract: This invention describes a device effective in maximizing the power output of a rotor in a fluid. This turbine uses a rotor (2) similar to HAWT but placed in a vertical position enclosed in a static diffuser with the shape of an inverted wing.

Abstract: People, especially children, need a small amount of illumination to orient themselves and navigate around a darkened room. Children often have trouble calming themselves down at bedtime. Finding the fan and light controls on a ceiling fan is difficult in the dark. Ceiling fan blades and hardware that incorporate phosphorescent materials addresses each of these problems: they provide a night light effect without using electricity.

Thus the air inlet of the fan unit opens in a direction opposite to the second opening communicating with inside of the room. As a result, sounds such as operation noises from the fan unit that are transmitted to outside of the fan unit chiefly through the air inlet can be made to resist being transmitted through the second opening into the room, so that the noises can be reduced.
