A mechanical rectifier (100, 200, 300, 400, 500) efficiently rectifies or converts alternative clockwise and counterclockwise rotation of a main handle (180) or other active driving element (660) into unidirectional rotation of a main shaft (102, 202, 302, 402, 502, 602). This mechanical rectifier is useful in manual tools such as a "non-waste screwdriver", which eliminates the wasted hand motion inherent in all ordinary hand tools, and in energy-saving devices such as a wave-powered electrical generator. The basic mechanical rectifier includes a shaft, two driving elements (120, 124, 220, 224, 320, 324, 420, 424, 520, 524, 624), and a reversing mechanism (108, 208, 308, 408, 508) coupling the two driving elements so that they can only rotate in opposite directions.
