Thomas Edison, closely following the alternative physics work of Albert Einstein and Max Planck, which convinced him that there was an entire reality unseen by the human eye. This led to the last and least known of all Edison's inventions, the spirit phone. His former associate, now bitter rival, Nikola Tesla,was also developing at the same time a similar mysterious device. Edison vs. Tesla examines the quest of these rivals to talk to the dead, and reveals:

• • Edison's little-known near-death experience formed his theory that animate life forms don't die, butrather change the nature of their composition. It is this foundational belief that drove him to proceed withthe spirit phone.
  • Tesla monitored Edison's paranormal work, with both men racing to create a device that picked upthe frequencies of discarnate spirits, what today is called EVP (Electronic Voice Phenomenon).
  • Both men were way ahead of their time, delving into artificial intelligence and robotics.

Although mystery and lore surround the details of the last decade of Edison's life, many skeptics havedenied the existence of the mysterious spirit phone. The authors have researched both Edison's andTesla's journals, as well as contemporary articles and interviews with the inventors, to confirm that testswere actually done with this device. They also have the full cooperation of the Charles Edison fund,affording them access to rare photos and graphics to support their text. Edison vs. Tesla sheds light onthis weird invention and demonstrates the rivalry that drove both men to new discoveries.
