Abstract: A shovel lifting/throwing device for removing material from a surface requiring little effort by the user to lift and throw the material, the shovel having a blade and a handle wherein there is a lifting/throwing device, comprised of a lifting arm pivotally fastened to the middle section of the handle running down generally parallel the handle to the under side of the shovel blade in the vicinity of the surface, a hand grip located above the lifting arm moves up the handle as the user begins to lift the load, it being connected by a cable to a mechanism, actuating the mechanism that engages the lifting arm, pivoting the lifting arm out and away from the under side of the blade into contact with the surface and lifting the blade off the surface, greatly reducing the effort required by the user to lift and throw the load.

Abstract: A hybrid ocean thermal energy conversion (OTEC) system, including an energy generation sub-system for receiving warm sea water, evaporating a working fluid at a natural depth of the received warm sea water to produce a working vapor, and generating energy from the working vapor and a pumping sub-system for pushing cold sea water up to a natural depth of the received warm sea water and condensing the working vapor with the cold sea water.
