Tesla also figured out that there is a frequency that al life resonates on, the pulse of the earth, 7.83 Hz, that is caused by the Schuman Cavity in the ionosphere. He realized that you can manipulate this frequency by sending charged particles into the ionosphere and alter, not only the weather, but you can alter the mental state of entire populations. 10.8 Hz causes riotous behavior...6.6 Hz causes depression. Tesla was worried this information would fall into the wrong hands...and it did. In Alaska there is a project called HAARP run by the US governmnet..."ELF waves produced from HAARP, when targeted on selected areas, can weather-engineer and create mood changes affecting millions of people". Tesla's discoveries yet again being used to manipulate humanity instead of help it.
