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.
Windmills produce electricity by electromagnetic induction, the process in which the movement of magnets in a magnetic field generates electricity.
