Chapter Review: Edison vs. Westinghouse: An Epic Struggle for Power

This chapter is reviewed from Miracles and Massacres: True and Untold Stories of the Making of America by Glenn Beck with Kevin Balfe and Hannah Beck, Threshold Editions, New York, 2013.
The struggle between alternating current and direct current was significant in our country, and determined how the power grid in the United States would go.  Nikola Tesla actually worked for Thomas Edison, and had developed things for him using alternating current.  However Edison was totally committed to direct current, so in the end Tesla left and joined George Westinghouse.  Alternating current had some advantages over direct current.  It could be transported over longer distances without losing as much power.  This made it so the lines used less copper in transmission.  At the time the price of copper was over inflated, which was a hindrance to Edison.
However Edison had developed citywide systems based on direct current.  He wasn't going to give up the power grid without a fight.  He tried to paint alternating current as being dangerous.  It was the spark of Edison which used alternating current for the electric chair.  He contended that many people would die if the grid went to alternating current.  He publicly proclaimed the use of the electric chair.  However when it was used it wasn't quite as effective as believed, as it took several attempts to kill the condemned.  Westinghouse had his opening.  The pinnacle was being able to light the World's Fair Columbian Exposition in New York.  After successfully bidding on this, at a price half that of Edison.  From there Westinghouse won the Niagara Falls contract, using Tesla's advances.
In the end, Edison would lose control of his power company, and would focus on film and mining adventures.  His company became General Electric.  Westinghouse would eventually also lose ownership of his company to bankers, but he continued in other interests as well and controlled many patents.

Movie Review: Benjamin Franklin: Scienist and Inventor

Benjamin Franklin: Scienist and Inventor, Nest Hero Classics, Living History Productions Inc.
This is Ben Franklin a the inventor, who worked with electricity.  There was much we didn't know about electricity.  Study of electricity started as a way to do some tricks.  But Franklin was sure there was something useful that wold result form his studies.  His big realization came when he determined that lightning was electricity.  There were many fires as a result of lightning. 
However there must be opposition to every bit of progress.  Those who felt that lightning was God's way of giving out punishment thought such an idea was heresy.  Franklin, after realizing the link, next became determined that he could control the electricity to prevent house fires.  However he still needed proof to back up his theory.  This is where we see Franklin with the kite, trying to prove there was electricity in the lightning.  His son helped him.
His test was a success.  The result was the lightning rod.  This allowed tall buildings to be relatively safe as the lightning would strike the rod, and the electricity would be channeled away form the home or building and into the ground.
