Free Energy Fountain Of NIKOLA TESLA

On October 13th 1914 Nikola Tesla filed an application for patenting his new fountain that was self regulating as well as overunity device which can be termed as free energy device in today's terms this device could run water like a fountain and could also rotate a shaft which can be used connected to other machines to derive the mechanical motion from it here is the patent for that and picture below as well as the text taken from the book.

To all whom it may concern:
