Ravana -an epic TV series in Sri Lanka Depicting origin of Sinhala people
Posted on June 25th, 2019

Sri Lanka

Raavana, the ancient Lankan monarch who is known to have excelled in technology, aviation, medicine, state craft and music. Ravana is considered to be a descendant of Yakka clan in ancient Sri Lanka and the ancient dynasty of  Sinhala people in Sri Lanka .
Name “Yakka” believed to be derived from the Sinhala word yakada (Iron) since this ancient civilisation has historically mastered the technology of Iron smelting  and producing steel for weaponry and household items.

Every Sri Lankan should watch this television epic which was produced successfully after a complete review of the historical evidences.

BEFORE the development of the blast furnace, iron smelting was achieved by ore reduction at temperatures below the melting point of the metal, forming an agglomerated ‘bloom’ of low-carbon iron and slag. The forced-draught (bellows-operated) shaft furnace known from archaeological studies is usually regarded as the pinnacle of this early smelting technology1–3. Examples of natural-draught furnaces, in which gas buoyancy in a shaft of sufficient height induces a draught adequate to drive the smelting process4, are also known, but are generally regarded as disappointingly inefficient by comparison5. Here I report the discovery and excavation at Samanalawewa, Sri Lanka, of a previously unknown furnace type. The furnaces are all situated on the western margins of hills and ridges, where they are exposed to the strong monsoon winds. Field trials using replica furnaces confirm that this furnace type uses a wind-based air-supply principle that is distinct from either forced or natural draught, and show also that it is capable of producing high-carbon steel. This technology sustained a major industry in this area during the first millennium AD, and may have contributed to South Asia’s early pre-eminence in steel production. https://www.nature.com/articles/379060a0

Ancient Smelter Used Wind To Make High-Grade Steel

SWORDS of super-hard Damascus steel helped Islamic armies sweep west to the doorstep of Christian Europe and fight the Crusaders to a standstill nearly a thousand years ago. While researchers have long known where the steel for these weapons came from, they weren’t sure of all the techniques used in making it.

Now evidence unearthed in Sri Lanka has shed new light on this early manufacturing process – and overturned some long-held assumptions. In particular, the findings indicate that the ancient metalworkers used unique furnaces that harnessed the mighty monsoon winds to produce high-quality steel on an industrial scale. Until now, experts have assumed that the steel would need to be refined through several steps. They had dismissed such wind-driven technology as impractical.

Moreover, these unique devices produced in one step steel that took competing technologies several steps to refine, according to archaeologist Gill Juleff, who made the discoveries and successfully tested full-scale reconstructions. The furnaces formed the basis for an iron and steel industry on the island that reached its zenith during the first millennium AD.

    Those techniques used to make high grade steel and marvelous irrigation systems have been in the blood. perhaps those ideas mus have been in our systems when we decided to have the steel mill in Athurugiriya where they found some iron ore. I too worked in that mill during its construction as vacation trainee under Russians. I know one such trainee assembles a whole overhead crane that carry a heavy load of 50 or 60 tons and he ended up being a prof of our uni.

    Where have all those talented people gone?. As, Hon. Patali says most of them are in Melbourne. The universities have been ruined by JVP and politicized professors and lecturers. So, no worthwhile teaching goes on in them. The most suitable person to be the local rep of a tech company is a person who has the least knowledge about its activities. I asked a friend of mine by an email, why he decided to become a farmer after retiring while his contemporary with same qualifications in the US today is a billionaire in Apple, he only copied to someone with a email address “[email protected] and said we must discuss, but he never did. I found that the email belonged to some NGO. This explains what happened to us: a conspiracy to keep us away from technological advancement; a strategy adopted by our adversaries to send us down the pallang (precipice).
