Abstract: One of the barriers to greater adoption of small turbines is their aerodynamic interference with each other, and hence the need to separate them. Certain types of vertical axis turbines, the drag types, can actually enhance each other's performance when placed close to each other under the right conditions.

Abstract: The location of in-pipe turbines within a piping system and their relationships to other devices in the piping system is dependent on several factors for the ideal operation of these turbines, whether from the nozzle shooting liquid into air, or providing a stable pressure to the turbine and the generator. Several solutions to this issue are presented.

Abstract: A wind turbine, particularly vertical axis, whose diameter is extensible and retractable, either from the length of the arms or the angle of the blades, or both, has advantages in operating in low wind speed regimes and surviving in high wind speed, regimes. The current application describes how to construct such a turbine, particularly the control mechanisms and the optimal aerodynamic configurations of the blades.

Abstract: An in-pipe turbine has uses in energy storage and circulation. Specific applications are in storage systems working by elevation, smart grid systems, pressure release, and heating/cooling systems. Storage and release of electrical energy are important parts of an electrical grid. A system for storage using particulates is presented. On a higher level, a water system can interact with an electrical grid in order to use and provide electricity and convey water in a more efficient manner. The connection of a smart water and smart electrical grid, which may include the use of an in-pipe hydroelectric turbine, is presented.

Abstract: Aspects of the manufacturing of Flow Deflection Devices (FDDs) for wind turbines are presented as a system that requires adjustments in order to improve power output and adjust for changes in different conditions yet provides stability of shape.

Abstract: The use of a shroud surrounding turbine blades to enhance the energy output creates a distribution of wind speeds in the plane of the blades. A unique class of such shrouds previously patented by the author creates zones of higher velocity near the tips. In order to take advantage of this new distribution of velocity, new principles of propeller design are required. One of the designs involves increasing the P/D ratio and the PHI in the outer portion of the blades. This solution works for liquids and gases.
