from Nikola Tesla
to Sava Kosanovic
New York, N.Y.
March 1, 1941

I thank Dr. Macek and you for the happy news.  It is important that you know the following: eight years I developed a new title using 50 of my patents of which one third are not applied.  In the system there are no electrons.  Energy goes into the same direction without any distribution and the same on all sides of distance.  It contains neutrons.  The air is equal to a diameter of hydrogen.  It can destroy the largest ships afloat.  There is unlimited distance of travel.  The same is for airplanes.

One will need nine stations: for Serbia; three for Croatia and two for Slovenia and everyone needs 200 KW which can defend our dear homeland against any type of attack.

The contents of one bomb can be exploded in the air.  I add that in the station one must have a small generator or battery of 30 volts for activation.

Express my deepest respect to Dr. Macek and accept the warmest greetings and thanks.

Your uncle, Nikola Tesla

As though I am poor with words. I still didn't explain it enough what would be necessary to increase up to twelve stations: eight in Croatia, each of the same construction like at Wardenclyffe and only 20 meters high - a ball five meters in diameter - the station would be using diesel oil for energy with mechanical action - my air turbines, steam powered, electrically or other manners of transforming into alternating electrical current with sixty billion volts pressure without danger. I am waiting for Governor Subasic to select one station on top of Mt. Lovcen. There will not be any light, electrical energy will deliver particles through space with the speed of 118,837,370,000 centimeters per second. This is 394,579 the speed of light. As I said about airplanes it can be used for tanks, trucks, automobiles and various machines in factories, with hydroelectrical wheels and unlimited other machines. The particles can be larger than that of the diameter of an Hydrogen atom with metals of all kinds of materials and sent to all distances and good results in war and bring about peace. Particles are practical with neutrons, because, they are 3,723 times [heavier] lighter than electricity or electrons that cannot penetrate space for great distances. In my attempts with an effective 20 million volts, electrons carried 40 times more electricity than normally and penetrated two meters in depth and terrible damage in a moment each. I have to finish because that I give you a fresh view.

Warm Greetings, I remain your uncle, Nikola
