PS: This guy is the source for a LOT of bad ideas about Tesla:
   [1]https://en.wikipedia.org/wiki/David_Hatcher_Childress

   He wrote something he called "The Autobiography of Nicolai
   Tesla" *and* listed Tesla as author... and himself. The man is
   ALSO a fan of Von Daniken, author of the Ancient Astronauts
   books.

   I read Von Daniken when I was 11/12 yrs old and ate it up.
   Believed for about two years. By the time I was 14, I knew it
   was bullshit. THEN 10 years later, X-Files comes out with the
   same shit in it.

   Fun stuff, but taking it seriously? No.   Another common source
   attributed to Tesla was written by:
   THOMAS COMMERFORD MARTIN
   Editor The Electrical Engineer; Past-President American
   Institute Electrical Engineers 1894 who wrote "THE INVENTIONS
   RESEARCHES AND WRITINGS
   OF
   NIKOLA TESLA"

   Also shows Tesla as author online. I really wish automated
   software would attribute things properly. Books ABOUT A PERSON,
   whether authorized or not, ARE NOT WRITTEN BY THEM.

   Ugh.
