…Dew is like our Earth,
so solid but also so fragile.
We all are responsible that this morning miracle should never be transformed into an acidic, hazardous liquid so that dew remains a symbol of purity and innocence …

Russian engineer, Friedrich Zibold. In Féodosia, in Crimea, during the summer 1900, while leveling its forest district, Zibold discovered large conical stone heaps, of volume approximately 600 m^3 volume.
In the majority of cases, remnants of clay pipes
surrounded these tumuli. Zibold concluded, as will be shown later, wrongly; but which gave rise to an astonishing construction, that these stone heaps were dew condensers. He decided that the tumuli were used to feed with of drinking water the antique Feodosia.
To verify his assumption, F. Zibold built a condenser functioning on principles that he thought identical to those of the old condensers. For this experiment, Zibold choosed a place at the top of Tepe-Oba, close to Feodosia, at 288 m elevation. He built a stone condenser, in form of a cup, 1,15 m depth and 20 m diameter. The cup was filled with sea pebbles from 10 to 40 cm in diameter, arranged in the form of truncated cone 6 m height and 8 m diameter at the top. The condenser began to be operated in 1912, and gave till 360 liters of water per day. The experiments had to cease in 1915 because of leaks in the base. Partially dismounted, it was completely abandoned. Today, there remains only one gigantic cut 20 meters in diameter.
quote from Marq De Villiers:
…”But for me, a small and largely forgotten example of technological inventiveness, and one of the most beguiling, is the work of the Russian Feodor Zibold in the early 1900s.
  Zibold was a “natural scientist,” as they were then called, a philosopher of nature, a man consumed with a childlike curiosity about how things really worked. There were people like him all over Europe a hundred years ago, men of independent means and independent minds, all imbued with the kind of sunny optimism that goes with exploring where none other had been before. Charles Darwin is the most famous exemplar of this agreeable species. Zibold came later, but he was operating on the fringes of Europe, in the last tottering days of czarist Russia, and could be forgiven his dilatoriness. And, unlike Darwin, he was often spectacularly wrong, which only adds to his charm.
  One day late in 1906, when he was taking the waters in the Crimea, he came across a local legend that the ancient Greeks, who had built an important provincial capital at Theodosia (now Feodosia, Ukraine), had mastered the morning dew: they had become so proficient at collecting and dispensing it that they had supplied the whole city with its fresh water, using neither well nor brook.
  Zibold was captivated by this notion and determined to recover the secret. Once he started to look around, the evidence was everywhere. Lying about on the ground were stony tumuli, undoubtedly remnants of ancient dew collectors, and surrounding them were clay pipes, which had clearly been used for conducting the water to storage cisterns. Filled with enthusiasm and energy, he bullied the local agricultural community into helping him build his own massive dew collector, a stone reservoir 20 meters across, in its center a pyramid of stones and pebbles 6 meters tall. Halfway through construction he ran out of money, and it wasn’t until 1912 that the marvel was finished. And, indeed, it worked: a yield of 350 liters per day was reported, not exactly city-slaking news, and not much water per ton of rock, but something.
