The issue of how the ancients made powerful solar concentrators has plagued theories from Archimedes to the Alchemist, from Asia to the Americas. Here there are no excuses, it is shown explicitly that if a smaller section of a sphere is used, it’s approximation to a perfect parabola increases exponentially. This means that if twenty degrees of a spherical surface is used, it has an accuracy of around one percent, whereas if five degrees are used it is near perfect. The concentration factors can be over two hundred thousand times depending on dish size and focal length chosen. A perfect parabola, in theory will concentrate sunlight infinitely, however perfection is an impossible goal. By using spherical surfaces, the task becomes a little easier once the build methods are understood.
The math that underpins the idea of spherical reflectors is indisputable, but it is only the functional physical objects that most people fully believe. It is also a matter of showing that the ancients had the requisite technology to build the devices in order to convince of their old world roles. Simply put, to make a spherical surface of seven degrees requires only a pendulum and a cutter or grinder. This can be combined with a potter’s wheel to speed up the process and guarantee the surface. See diagram.
With this set up an ancient artisan could make devices so powerful they would vaporize virtually anything at their maximum power. Beneath the maximum, there are points where materials can be melted or just warmed. In the Ancient Solar Premise many of the techniques are demonstrated and then placed in their historical context. This includes the roles played in ancient stonework, fine art, jewelry, weaponry, science and chemistry.
It becomes clear after a few examples that many of the anomalous artifacts from antiquity can only be explained by these devices. This proves to most that these devices were indeed used in many ancient cultures. Probably the most compelling relics are the vitrified stones that are found in locations as diverse as Asia to the Americas. These finishes cannot be created by any other available methods. This evidence raises many other questions about the development and decline of several disciplines and cultures for that matter.
The study of alchemy has been given short shrift by most scientists, the more prosaic recognize the origins of chemistry within the alchemical sects. However, the focus on lead to gold transforms has left most with little doubt that these guys had a poor understanding of chemistry and lacked the tools for the procedures. With these incredibly powerful solar devices on hand, the ancient technologist had the ability not only to create certain materials, but experiment with many more.
A short example in the field of ceramics illustrates the point. It is a widely held view that ceramics evolved with the evolution of the wood kiln and complex firing techniques. Most stones when placed in a fire will not alter their composition in anyway at all, yet this leap in technology was made throughout the ancient world. Jordan contends that it was through the use of these mirrors and sunlight that the first experimental work was carried out. Quite simply it is easy to expose a wide range of natural and man-made materials to temperatures in excess of a thousand degrees using parabolic concentrators.
Jordan’s research followed a similar path, various metals, rocks, gems, bricks and ceramics were simply left in the beam for a few minutes to see what happened. Even kids today appear to be treading the same path with homemade reflective dishes. Surely this is not beyond the scope of an ancient craftsman, who’s conventional methods would involve elaborate kiln set ups and mostly result in failure. The inference is that the development of these fields owed a great deal to the use this exquisite solar technology.
