"A Machine to End War" by Nikola Tesla
Nikola Tesla, has been called the father of radio, television, power transmission, the induction motor, and the robot, and the discoverer of the cosmic ray.
in this article Tesla descibes a method for obtaining free energy and force fields, consequently eradicating all wars... high ideals indeed.
He does not disappoint with the rest of this article, which ranges from nutrition to religion. he does briefly touch on eugenics which is a false science i cannot agree with (being a hippy i see value in everyone and everything!), however the rest of this article is enlightening and you can't help wondering at the possibilities it embraces.
