Fresh look on wind power generation Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski [3749]-25/06/2017, {149}-( 1 4)- 0 8. 07 .2017 Abstract   It is a new kind of a wind power generator. Its energy effectiveness can be close to 100%, while it has very simple design, and its electricity is about 0.3 USA cents per kWh, because a lion share of the said cost is a share of a geared electric generator. It works in open sea in principle, while global wind kinetic power is about 20.0 milliard kW. The power generation unit is a small pilotless boat with a flat sail. Four small floats placed symmetrically at a distance from the boat, are serving to compensate a torque force of the wind on the sail. A relatively small water wheel with three blades in a form of window leaf each (WWWL) is fixed underwater to the boat moved by the sail. At any moment only one window leaf is closed by the fron...

New kind of a wind power plant (WPP) Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski [3749]-25/06/2017, {149}-(13)-07.07.2017     Abstract   It is a new kind of a WPP invented by me. It is most energy effective than any other WPP     and has very simple design, and its electricity is about 0.3 USA cents per kWh!!! It works in open sea in principle, while global wind kinetic power is about 20.0 milliard kW. The power generation unit is a small pilotless boat with a big sail of canvas or plastic foil, and four small floats placed symmetrically at a distance from the said sail are serving to compensate a torque force of the wind on the sail, and a WTWB (water turbine with window leaf’ blades) fixed underwater to the boat, it produces electricity. A system of such boats is a wind power plant. For example, the sail of 20 meter width and 10 meter height serves to har...
