"Imagine a beam of energy that could bring down planes from miles away with nothing but electricity. Imagine an invisible wall of energy protecting a country from invasion, acting as an electric fence that could vaporize enemy soldiers the second they step foot inside. Sounds like something most militaries would love to get their hands on, doesn’t it?
The dream of this kind of “death ray” has inspired weapons developers for decades. But one brilliant inventor, Nikola Tesla, claimed to have actually created one."

"At the end of the tunnel there was a massive stone gate, which was protected by an invisible energetic barrier.
Three members of the first special intervention team tried to touch the door, and immediately died of cardiac arrest.
Any object (rock, plastic, metal or wood) threw at the barrier, immediately turned into fine dust."

"Instead of lightning, Tesla said his new weapon would harness a beam of metal ions hurtling along at 270,000 miles per hour. As for how this beam was possible, Tesla was always coy, citing new laws of physics that “no one has ever dreamed about.” He nevertheless bragged about his work to any reporter who would listen: the “all-penetrating” beam would pack 100 billion watts into just one one-hundred-millionth of a square centimeter."

"He has perfected a method and apparatus, Dr. Tesla said yesterday in an interview at the Hotel New Yorker, which will send concentrated beams of particles through the free air, of such tremendous energy that they will bring down a fleet of 10,000 enemy airplanes at a distance of 250 miles from a defending nation's border and will cause armies of millions to drop dead in their tracks.
“Death-Beam” is Silent.
This “death-beam,” Dr. Tesla said, will operate silently but effectively at distances “as far as a telescope could see an object on the ground and as far as the curvature of the earth would permit it.” It will be invisible and will leave no marks behind it beyond its evidence of destruction."

"According to Tesla, the particle beam weapon, also known as “death ray” or “peace ray”, was a weapon that would be capable of being used against an entire ground infantry or for anti-aircraft purposes. This single weapon would be so powerful that it would be able to destroy anything that is in a radius of 300 to 400 kilometres. This would have proved to be particularly useful in preventing wars, as it would be able to put an end to it before it starts at all."

"In the 1980s, US President Ronald Reagan created the Strategic Defense Initiative – nicknamed “Star Wars” – inspired by the concept of Tesla’s Death Ray and particle beam weaponry. Many believe the US government’s continued interest in Tesla’s theories may explain why some of his papers are still missing to this day (see below)."
