Machu Picchu, as well as all series of other historical construction, is for present science a mystery, especially from angle of exploitation. Most different hypothesis try to explain hard to no end these unique impressive buildings, temples and altars. One theory has said that Machu Picchu had been established like inaccessible strategic fortress, after other assumption the town had been the last refuge of members of regnant caste. The other theory has said that it had been the place for observation of orbs, by others there had been enacted ceremonies, rituals, etc. I suppose that the right hypothesis will be able to emerge only from reply to the question why people had exerted so much struggle with supply of large granite blocks across mountains and deep valleys, while other rocks had been there of sufficient number. A transportation of rock had created the utmost rate of work difficulty of the whole construction therefore this activity must not be overridden. By long-term experimentation I have obtained the experience that every rock has its specific code of energy components. Two or more sorts of rocks placed side by side, so that their energy spaces blends, will obtain common, but different code from the previous. For troublesome transportation and different codes can be deduced that some combination of rocks could have had positive effect to human health. I cannot imagine other motivation, which could have provoked such pep for superhuman effort at transportation of ashlars. Even the fact that different sorts of rocks had been transported from large distances also to other meeting-places of people – to Great Pyramid Stonehenge and other historical constructions, thought the rocks had been at place enough, suggests to it. Because these transportations had not been explained till this time, can be only stated that a solving is outside the sphere of known facts. Another obscurity in the area of construction Machu Picchu is a fenced place, whose two walls are in accurate right angle and opposite side is shaped by perfect half-circle, known like Torreon (Tower). And just that perfect semicircle from stonework creates the secret of the whole construction – it cannot be placed among known constructional components. The finding resulting from my research of interaction of mass offers an answer to the secret of Torreon. Resembling semicircles in masonry were inbuilt practically into each sacred building and in architecture are called “Apse”. The cathedral in Chartres has a large apse behind the altar constructed from five small apses. Placing more apses in sacral buildings is not a rare phenomenon. Semicircular masonry is considered only like an architectonic element, however it is easy to prove that it is an energy element, too. Its function is conformable to inside of a bend of watercourse, where happens to concentrating of energy components. The identical energy characters have all vaults and by cyclical constructions is resulting effect heaps considerable. The necessary condition is of course to ensure the sufficient number of energy for their mass. It can be reached by sitting of building to energy components or by construction of towers and dome-shaped vaults. The construction Torreon can be valuated thus that way: the whole section is situated in common energy space of two mountain tips, which has certain energy value. At one place the builders wanted this energy enlarged, which was disposed by rearing of two accumulative walls. The other semicircular wall there creates energy over-voltage. I suppose that resembling function had even the other mysterious object called “Temple of three windows”. The windows were the part of massive wall, built up from imported cyclopean granite blocks. The temple has only three walls: one with windows leading eastward and two walls at the sides. A stone pillar over two meters high is seated on the open western side and two horizontal rocks on its flanks, which closely fit tightly to it, there are placed. The pillar is situated exactly opposite the middle window. The energy components of three stony walls intersected in this case the pillar with contiguous stones and created in its mass needed energy voltage. Area Machu Picchu has even another secret, for which is impossible to find a warrant without further specific research. I suppose that the whole area had the identical function like all sacral constructions from zikkurats, pyramids, cromlechs, mosques and cathedrals to churches of our era – by completion of energy they created creative effect in cellules of their visitors, who listened at the same time to suggestions of their brains. Also this hypothesis, as well as any new information, will invoke questions. But I can propose its verification by reputable scientific procedure. Biophysics has mentioned capacitive merits of cellular membranes, which can be proved by the help of measuring appliances. I suppose that it will be of interest to compare the energy value of cellular membranes near a group of people before they enter in a cathedral and after some few hours stay inside. By the identical method even among animals can be verified the energy value of pyramids, bends of watercourses, “Juryska” houses, hospitals with large death rate, and other energy places. Positive results of measuring would invoke perhaps an interest about construction of new measuring apparatus.
