Where horizontal axis wind turbines (HAWT) or propeller wind turbines are often touted as having the better efficiencies (32-38%), most are generating electricity for utility supplied power. All utility or centrally generated electricity is subject to transmission losses do to resistance in transmission lines and other necessary equipment. This makes locally generated electricity more efficient, more reliable and more secure. Built environment safe vertical axis wind turbines (VAWT) offer greater efficiencies and reliability than utility wind farms while offering increased reliability.
Importantly, most Built Environment Wind Turbines (BEWT) are vertical axis wind turbines (VAWT).
New support for urban wind farms and ag-wind arrays, it's in the science New technology and verification of data from studies involving VAWT arrays are offering new opportunities for communities, urban and rural. Star Sailor is at the forefront of new performance adaptive biomimetic VAWT technology. Our patented VAWT products are built environment safe and tested in hurricane winds, icing weather and in urban wildlife habitats along with our animals and families we have observed the reliability of our US produced wind energy systems.
Whittlesey et al observed that utility type wind farms comprised of horizontal axis wind turbines (HAWT) actually experience reduced efficiency in close proximity to other HAWT towers. Research on vertical axis wind turbines (VAWT) suggest that closely spaced VAWT's experience increases in an individual turbine’s power when placed in close proximity as in an array and yield much higher power outputs for a given area of land or installed space. Whittlesey et al also reported on a potential flow model of inter-VAWT interactions to investigate the effect of changes in VAWT spatial arrangement on the array performance coefficient, which compares the expected average power coefficient of turbines in an array. Star Sailor's stacked turbine towers control vortices internally increasing performance of the wind turbines which were first observed in wind tunnel testing for Star Sailor by Dr. James Delaurier of the University of Toronto. Other efficiencies are being currently evaluated.

Local power advantage: Security, resilience an sustainability
Star Sailor Energy is leading in innovation in critical areas of local microgrid and direct DC charging increasing electric vehicle accessibility. The eV has been called the electric grid's moving target. As new infrastructure design is nearly underway, the value of local energy generation is gaining support in the business sector. As a leader in local energy technologies, Star Sailor Energy and its subsidiaries have focused on products to reduce dependence on grid centered electricity and improve energy security.
Ag-wind by Ag people
Star Sailor's founder, Pamela Menges, knows the challenges of farming and the resilience of remote communities. The Ag community has always led in self-sufficiency. New wind technologies like Star Sailor T-Com™ Series and the AGCom Tower (below) offer solutions for IoT, remote sensing, security and power operations. These multipurpose uninterruptible power supply (UPS) platforms were designed and tested to provide rugged, reliable and low-maintenance power. Star Sailor's partners include ranchers and remote locations in the desert Southwest and Mountain states. Please contact us with your requirements. We are here to assist
 Star Sailor's on-going commitment to scientific and engineering excellence has produced new tower configurations creating efficient, cost effective local power.
Star Sailor's 36-kW towers (above) in development and planned for demonstration in 2022. The VAWT AgCom Towers support electrical generation, power pumps and support mechanical power for irrigation and water treatment in a multifunctional package designed by Ag-people for Ag-people.
Data from studies completed at the
California Institute of Technology have reported that installation of vertical axis wind turbines (VAWT) in an array, such as US produced Star Sailor VAWT built environment safe technology, can provide higher-energy density than the more familiar horizontal axis wind turbines (HAWT) or propeller towers. The study completed by CalTech's Robert W Whittlesey, Sebastian Liska and John Dabiri was published in 2010 in
Bioinspiration & Biomimetics.
