Vertical-axis aeolian rotary optical reflector or radiator - has two surfaces in mirror-image relationship fixed to or removable from axis in spherical bearings

摘要

Two equally thin-walled rotor surfaces (1, 1a) carry reflectors (3) held (6, 6a) in recesses (4) with rounded edges (5). Horizontal covers (7, 7a) are shaped to match the rotor surfaces. The pressure of air currents sets the assembly into rotation about a vertical axis (9) of small dia. topped with a small ball (10) and set in bearings (8, 8a) in the cover (7, 7a). The axis (9) may drive an electric generator enabling a light beam to be radiated from the rotor. USE/ADVANTAGE - For safety of pedestrians, cyclists, motorists and sailors, attention from all directions is attracted by the optical effect of the rotation.
