No matter: they concurred unanimously in... every point with what had been thought best in Philadelphia.. The commissioners named the city Washington.. They also had to name the ten mile square, mandated by the Constitution, that the the city was in. In 1791 there were already two existing towns in that ten mile square, Georgetown and Alexandria. They chose the name Columbia.. As far as I can ascertain there was no debate about Columbia either.
A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain, pump water, or both. Thus they often were gristmills, windpumps, or both.
A turbine is a device for converting the energy in a moving fluid into mechanical rotating energy. There are big turbines at the bottom of dams that convert the energy from pressure and velocity in water into rotating mechanical energy to drive huge generators.he energy in is the kinetic energy from the wind's velocity and air density that flows into the area swept by the turbine blades. It is not possible to convert all of the wind's kinetic energy into mechanical energy. Some energy must remain in the air leaving the turbine.
