Experiments With Alternate Currents of High Potential and High Frequency

Author: Nikola Tesla
A lecture delivered by Tesla before the Institution of Electrical Engineers in London. Alternate Current (AC) was in large part created and perfected by Tesla, who proved it to be more effective at transmitting power than Direct Current (DC). To this day, AC powers most things in our homes. Also outlines his work up to that time and allows us into the mind of a genius. The Appendix covers one of Tesla’s most astounding inventions, entitled The Transmission of Electric Energy without Wires.

Prodigal Genius

Author: James J O’Neill
The first full length biography written on the genius inventor, Tesla. The author was a Pulitzer Prize-winner and personal friend of Tesla, who once said the author understood him better than any man alive. Much of this information would not have been known had O’Neill not documented it. The genius of Tesla came from a mind that could see an invention in 3-D, from every angle, within his mind before he built it – perfectly.
Most were electrical, with dozens now used worldwide. Much on his eccentric personality, his competition with Thomas Edison, and how he made his first million before age forty. Money was not important; nor was The Nobel Prize, which he refused to accept. Only the science mattered.

The Coming of the Guardians

Subtitle: An Interpretation of the Flying Saucers as Given from the Other Side of Life
Compiled by Meade Layne
Where do UFOs really come from? Layne holds an inter-dimensional, etheric based theory. Much of his information was corroborated by the scientific work of Trevor James Constable or came directly from intelligence channeled through Mark Probert, the greatest psychic medium of his time. Layne was scientific in his approach until hearing Probert’s incredible messages, which independently verifies his research.
Covers propulsion systems, vibrational frequencies, and the sudden appearance of these craft more clearly than any scientifically based book could ever do.

The Flying Saucers are Real

Author: Donald Keyhoe
Was the first indepth, authoritative look at the flying saucer phenomenon and is considered to this day to be one of the best books on the subject ever written.
Extremely well researched with facts that were documented, containing none of the disinformation and hype that has crept into the field over time. The author was a retired Marine Corps Major who became an aviation writer, and was therefore perfect for the job of researching and writing this book.
Using his own knowledge and information from friends in the military, he came to the conclusion that UFOs originate from outer space and the U.S. military was engaged in a cover-up.
Includes documented cases with credible witnesses. Much is shown on how and why secrecy was enforced.

Extraterrestrial Entities and Technology Recovery and Disposal

Author: The Majestic 12 Group
Considered by many to be a Top Secret government document written by and for a secret U.S. group, MJ-12, in 1954, which was later leaked to the public. Contains detailed guidelines for military personnel to follow in the event of encountering and/or recovering extraterrestrial beings or crashed objects.
There have been heated debates about its authenticity over the years and evidence has been presented on both sides of the argument. Due to its shadowy origins, we may never know with certainty if this is a genuine document or an elaborate hoax. Worth reading and investigating for oneself.
