(anonhq.com) Most great inventions fundamentally change the society in which they exist. Since the people at the top of the social structure have more to gain by reinforcing the status quo, they suppress revolutionary technologies favorable to the world but dangerous to their existence.

Engineering genius Nikola Tesla was no exception. Here are some of those technologies, 'they' don't want you to know about Nikola Tesla. (Video below as well!)

Death Ray

Nikola Tesla claimed to have invented a "death beam" which he called Teleforce in the 1930s. The device was capable of generating an intense targeted beam of energy "that could be used to dispose of enemy warplanes, foreign armies, or anything else you'd rather didn't exist".

The so-called "death ray" was never constructed because he believed it would become too easy for counties to destroy each other. Tesla proposed that a nation could "destroy anything approaching within 200 miles… [and] will provide a wall of power" in order to "make any country, large or small, impregnable against armies, airplanes, and other means for attack". He said that efforts had been made to steal the invention. His room had been entered and his papers had been scrutinized, but the thieves, or spies, left empty-handed.

Tesla's Oscillator

In 1898, Tesla claimed he had built and deployed a small oscillating device that, when attached to his office and operating, nearly shook down the building and everything around it. In other words, the device could allegedly simulate earthquakes. Realizing the potential terrors such a device could create, "Tesla said he took a hammer to the oscillator to disable it, instructing his employees to claim ignorance to the cause of the tremors if asked". Some theorists believe the government continues to use Tesla's research in places like the HAARP facility in Alaska.

Free Electricity System

With funding from JP Morgan, Tesla designed and built Wardenclyffe Tower, a gigantic wireless transmission station, in New York in 1901-1902. Morgan thought the Wardenclyffe Tower could provide wireless communication across the world. However, Tesla had other plans.

Tesla intended to transmit messages, telephony and even facsimile images across the Atlantic to England and to ships at sea based on his theories of using the Earth to conduct the signals. If the project worked, anyone could have electricity by simply sticking a rode into the ground. Unfortunately, free electricity is not profitable. And this system could be incredibly dangerous for the global elite because it could profoundly change the energy industry. Imagine how different the world would be if society didn't need oil and coal to function? Could the great world powers maintain control? Morgan refused to fund the changes. The project was abandoned in 1906 and never became operational.
