Abstract: An energy generation system includes an inner tower, an outer tower and a plurality of wind turbines. The outer shell defines a wind or fluid amplifying surface. The plurality of wind turbines is carried by the outer shell and disposed relative to the wind amplifying surface to harness wind deflected by the wind amplifying surface.

Abstract: A method for securely mounting an elongated, insulating strip in an elongated metal profile section, the strip having opposed longitudinal edges and the profile section having an elongated groove with a slightly open mouth. The method comprises placing one edge of the strip into the elongated groove in the profile section, the strip extending out of the groove and the groove loosely holding the strip and then partly closing the mouth of the groove, simultaneously along the entire length of the groove, onto the strip to securely retain the strip to the profile section. An apparatus for use in forming a thermal break between a pair of profile sections, each profile section having an elongate groove along its length, and an insulating strip loosely held in the grooves and extending between the sections. The apparatus is a press having a bed to support a first die; the first die holding the first and a second profile sections in place, slightly spaced apart, parallel to each other, and with the grooves facing.

Abstract: A workpiece moving machine comprising: an elongate frame with an endless belt mounted on the frame and extending between the ends of the frame. A plurality of trolleys are slidably mounted on the frame for movement along the frame. Each trolley has a clamp for selectively holding a workpiece to the trolley. A first clutch on each trolley selectively connects the trolley to one run of the belt to move the trolley along the frame in one direction and a second clutch on each trolley selectively connects the trolley to the other run of the belt to move the trolley along the frame in the opposite direction. A brake on each trolley selectively brakes the trolley to the frame to prevent its movement along the frame.

Abstract: A method for use in making profile pieces. The method has the steps of feeding a profile into a work station, clamping the profile in the work station, and cutting it into a profile piece and a profile remainder. The profile piece is repositioned in the work station for further work by operably connecting it to the profile remainder while both the profile piece and the profile remainder are clamped, and moving the profile remainder. The invention also covers a machine for carrying out the method.
