Domagoj Nikolić, M. Sc. Independent Researcher, Imotski, Croatia BOSNIAN PYRAMIDS, ANCIENT MINING, WIRELESS TRANSFER OF ENERGY AND TESLA Abstract The purpose of this paper is to point out some often hidden facts about ancient mining in the Balkans and Bosnia in particular, as well as connections between Bosnian Pyramids, contemporary knowledge about electromagnetic phenomena and devices for wireless transfer of energy devised by Nikola Tesla. The goal is to point out the following: 1. Mining in the world is much older than what is widely considered. 2. Mining in the Balkans and Bosnia is very old and goes thousands, probably tens of thousands of years back into the past. 3. There are accounts and evidence that at least some of the old pyramids in the world had complete or partial casing of precious metals. 4. There were sophisticated and technologically advanced reasons for exploitation of minerals in ancient times which were not connected with the production of primitive weaponry, tools, decorative objects, etc. The end purpose was technology of energy channeling. 5. Precious metals at those times, just like today, were used as electromagnetic materials. 6. The design and function of the Teslaʹs Wardenclyffe Tower is essentially analog to the design and function of the Bosnian Pyramids.
