Abstract: An eduction industrial power system is provided. The system includes one or more vertical-axis wind turbine power plants. Wind is accelerated through a multi-floor eductor of the power plant. Each floor of the eductor is configured with a constricted portion designed to increase the air speed through the eductor, such that low speed winds enter the eductor and much higher speed winds exit it. A plurality of rotor-blade assemblies disposed in the constricted portion of each floor of the multi-floor eductor are mounted to, and rotate, a shared vertical-axis rotor shaft to generate electricity, via a generator. The electricity generated can be stored, used or channeled to an electrical grid, as desired.

Abstract: A golf club putting head includes a flexible cylindrical roller body having a striking face defined thereon and thereabout. The roller body has a central bore extending therethrough from end to end thereof and configured to mount the body over an axle on a lower end of a putter shaft such that the body can undergo rotation about and relative to the axle. The striking face on the body is yieldably conformable to the shape of a golf ball upon impacting the ball and is formed by an annular bed of multiple flexible projections formed on and about the body. The putting head also includes a pommel fitted on an outer end of the axle and configured for adjusting the rollability of the roller body on the axle so as to enable a player to hit the ball with an impact that will cause it to roll towards the hole.
