Austrian Electrical Engineer and Inventor Georg Wasserfaller visited Underground Labyirnth Ravne in Visoko on November 6, 2014. He owns a patent for the pyramid with exclusive application in medical and healing purposes.
Engineer Wasserfaller exercised a series of measurements during his visit to the prehistocial tunnels in the Bosnian Valley of Pyramids. He measured the record concentration of negative ions (anions) in the Healing Chamber in the range of 57,500 to 69,000 anions per cubic centimeter. This is so far the second highest measured value in the tunnels. For example, the concentration of negative ions on the top of Mount Igman in the pine forest is less than 5000, and in our homes only about a hundred.
Medical science recognizes the healing properties of high concentrations of negative ions that increase the level of oxygen in the blood, cleanse the atmosphere of dust and kill viruses and bacteria.
Presence of positive ions (cations) was much smaller. This was the reason that the engineer Wasserfaller finds remarkable healing powers inside Underground Labyrinth Ravne.
At the location of Mega-ceramic block K-2 he found three water flow beneath the K-2, and the location of the mega-ceramic block K-5 is located above seven underground watercourses. Impressed by what he saw, he decided to come and spend a week next month precise measurements.
In his view, different concentrations of negative ions in certain parts of the tunnel have benefits for different parts of the human body. He wants to specify and mark which tunnel section is good to cure certain health problems.
