Abstract: A man-made floating island includes platform units above the water with vertical members extending downwardly therefrom on which movable floats are mounted which move in response to wave action. Motion of the floats operates air compressors and the resulting compressed air is either converted to transmissible energy or stored in reservoirs for future use. Wave amplifiers may be disposed beneath the movable floats.

Abstract: Repair of pot holes in public roads, streets and highways is facilitated and improved by the use of a simple holding device which is firmly anchored in place in the pot hole before filling the hole with conventional road patching material which then permanently unites with the holding device.
