2. List of satellite map images with missing or unclear data

   en.wikipedia.org/wiki/List_of_satellite_map...

   Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as an amusement park, a beach, and parking lots) from its satellite ...

   Floor burnisher is the term for a high speed floor buffer that rotates its pad at over 1000 RPM. Closely resembling a large upright, wide-based vacuum cleaner with handlebar controls and requiring two-handed steering by beginners, a floor buffer uses one or more variable-speed circular rotary brushes to dislodge dirt and dust from and apply a ...

   The extremely dry soil conditions would have required hundreds of feet of rods to be driven into the earth to create a low impedance ground to protect the buildings from lightning strikes. In 1942, Herbert G. Ufer was a consultant working for the U.S. Army. Ufer was given the task of finding a lower cost and more practical alternative to ...

   "T" — Earth connection is by a local direct connection to earth (Latin: terra), usually via a ground rod. "N" — the earth connection is supplied by the electricity supply network, either separately to the neutral conductor (TN-S), combined with the neutral conductor (TN-C), or both (TN-C-S). These are discussed below.

7. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   For antennas near a half-wavelength high (180 electrical degrees [b]) the antenna has a voltage maximum near its base, which results in strong electric fields in the earth above the ground wires near the mast where the displacement current enters the ground. To reduce this loss these antennas often use a conductive copper ground screen under ...
