This original Invention was From Nikola Tesla; so credit should be given

A sensation of unbearable, sudden heat seems to come out of nowhere --
this wave, a strong electromagnetic beam, is the latest non-lethal
weapon unveiled by the US military this week.

"You're not gonna see it, you're not gonna hear it, you're not gonna
smell it: you're gonna feel it," explained US Marine Colonel Tracy
Taffola, director the Joint Non-Lethal Weapons Directorate, Marine Corps
Base Quantico, at a demonstration for members of the media.

The effect is so repellant, the immediate instinct is to flee -- and
quickly, as experienced by AFP at the presentation.

Taffola is quick also to point out the "Active Denial System" beam,
while powerful and long-range, some 1000 meters (0.6 miles), is the
military's "safest non-lethal capability" that has been developed over
15 years but never used in the field.

It was deployed briefly in Afghanistan in 2010, but never employed in an
operation.

The death ray or death beam was a theoretical particle beam or
electromagnetic weapon of the 1920s through the 1930s that was invented
independently by Nikola Tesla which he called teleforce. Blue prints for
his invention can be seen today.
