20120068464 | HYDROELECTRIC IN-PIPE TURBINE BLADES - The special circumstances of working with hydroelectric turbines in pipes require innovations in blade shapes and systems that are presented here. An example is streamlining of the blades greater than that found in traditional hydroelectric turbines. | 03-22-2012 |
20120068470 | MANUFACTURE OF WIND TURBINE ENHANCEMENT SYSTEMS - 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. | 03-22-2012 |
20120192514 | TELECOM TOWER VERTICAL AXIS WIND TURBINES - Attaching wind turbines to towers built for many uses is highly advantageous. The ways of doing that in novel uses and ways are presented. | 08-02-2012 |
20130094939 | IN-PIPE HYDRO TURBINE WITH AIR BUBBLE - An in-pipe turbine with the use of an air bubble in a new and unique configuration with electronic controls can improve the efficiency of in-pipe hydroelectric turbines. | 04-18-2013 |
20130129495 | HYDROELECTRIC TURBINE NOZZLES AND THEIR RELATIONSHIPS - Hydroelectric turbines in confined spaces depend heavily on nozzles and relationships involving nozzles and related turbine components in order to obtain maximal efficiencies for a wide range of flow conditions. | 05-23-2013 |
20130142657 | TWO-BLADED VERTICAL AXIS WIND TURBINES - Two-bladed vertical axis wind turbines (VAWT) have many efficiency advantages over turbines with other numbers of blades. Principles for making them in the ideal fashion are presented for both drag and lift configurations. | 06-06-2013 |
20130207390 | HYDROELECTRIC IN-PIPE TURBINE USES - 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. | 08-15-2013 |
20140167414 | VARIABLE DIAMETER AND ANGLE VERTICAL AXIS TURBINE - 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. | 06-19-2014 |
