 **کانتالوک 1500 سال پرانی آبی گزرگاہیں** کانتالوک آبی گزرگاہیں، جو نازکا تہذیب نے تقریباً پندرہ سو سال قبل پیرو کے بنجر اور خشک صحرا میں تعمیر کیں، آج بھی قابلِ استعمال ہیں اور اپنی مثال آپ ہیں۔ ان آبی گزرگاہوں کا نظام خاص طور پر پانی کی کمی سے متاثرہ علاقوں میں آبپاشی کے لیے تیار کیا گیا تھا۔ ان گزرگاہوں میں سانپ کی مانند بل کھاتے ہوئے سوراخ بنائے گئے ہیں جنہیں "اوکس بو" کہا جاتا ہے۔ ان سوراخوں کی مدد سے ہوا زیرِ زمین نہروں میں داخل ہوتی ہے اور ہوا کے دباؤ سے پانی کو زمین کے اندر موجود قدرتی آبی ذخائر سے کھینچ کر ان علاقوں میں پہنچایا جاتا ہے جہاں پانی کی زیادہ ضرورت ہوتی ہے۔ یہ گزرگاہیں نازکا تہذیب کی انجینئرنگ کا شاہکار ہیں، جو آج تک کام کر رہی ہیں۔ کانتالوک آبی گزرگاہوں کا یہ نظام جدید انجینئرنگ کے لیے بھی ایک معمہ بنا ہوا ہے کیونکہ یہ بغیر کسی جدید آلات یا تکنیک کے تعمیر کیا گیا تھا

  How Flying into the Middle of Hurricanes Began as a Bet Out of approximately 23,000 operational business jets in the world, this Gulfstream-IV business jet is arguably the most important one. You see, this jet plane is not just giving rides to CEO’s and celebrities. Instead it is filled with scientists. The scientists who not only save lives, but also save tens of millions of dollars for the American taxpayers each year. Owned by the National Oceanic and Atmospheric Administration, or NOAA, this jet's primary mission is to fly into hurricanes, as frequently as twice a day, during the Atlantic hurricane season. Hurricanes form over oceans and while satellites can detect and track them, they cannot predict their movement.   But more importantly, satellites cannot determine either the interior barometric pressure or the maximum sustained wind speeds at the surface, meaning that satellites cannot figure out how bad the hurricane actually is! The only way to get this i...

"Unlocking the Future: Emerging Technologies Set to Revolutionize Everyday Life"  "Unlocking the Future: Emerging Technologies Set to Revolutionize Everyday Life" Weapons systems have almost always relied on kinetic energy to destroy their targets. From arrows and bullets  to electromagnetic rail guns that have a muzzle velocity of 9,800 feet per second, military engineers have been designing their weapons to throw one object at very high speeds in order to destroy other objects. However, new and disruptive battlefield technologies like inexpensive drones and hypersonic missiles have shifted the balance and cost-effectiveness of traditional missile defense systems. And this has forced military engineers to investigate an existing, yet misunderstood weapon: Lasers.     Across air, sea, and land, this futuristic weapon is being developed, tested, and even used operationally. Lasers are bein...

  How The Internet Travels Across Oceans Submarine cables, according to the authoritative submarine cable map website, reveal a vast network of 493 active or actively under construction sub-sea internet cables crisscrossing the globe. These cables vary in length, from relatively modest 300-kilometer wires under the Black Sea to the gargantuan 6,600-kilometer Maria cable linking Virginia Beach in the US with Bilbao in northern Spain – a cable equivalent in weight to 24 blue whales. Worldwide, there's now approximately 1.5 million kilometers of undersea data wires, a significant infrastructure investment, typically costing between three and four hundred million dollars per transoceanic cable. These cables are not especially thick, roughly equivalent to the girth of a garden hose, but they are packed with layers of protective thixotropic jelly around the all-important fiber optic core, as well as multiple plastic sheaths and copper wiring to power the system. Despite their relatively ...

  Egypt is Building $5.2bn Artificial River Parallel to the Nile River In Egypt, the government has also been constructing 30 water lifting stations and a mega tertiary wastewater treatment project, Al Hamam plant, to guarantee a sustainable water source. The plant can treat 7.5 million cubic meters of agricultural wastewater per day, which, according to the Water Resources and Irrigation Minister, is the world's largest agricultural drainage project. Its water is enough to cover a large part of the New Delta project. The Watercourse consists of an open canal, while the smaller part is made up of pipes buried in the sand for the treatment and lifting of water.   President Abdel Fatah al-Sisi said the agricultural wastewater, which previously poured down in drains, is collected and triple treated. 'We are talking about 30 water lifting stations, each of which is a great engineering feat as they collect drain water against the natural slope of the land,' al-Sisi said. The...

  The largest gas pipeline mega project in Afghanistan     The largest tapiai natural gas pipeline project in Afghanistan with its implementation Afghanistan will become an economic Corridor between Central and South Asian countries moreover this project is considered the most beneficial project for Afghanistan this project to API is the Turkmenistan Afghanistan Pakistan end IA gas pipeline from Central Asia whose Roots Began in the 1990s after the participation of international oil companies in Kazakhstan and Turkmenistan due to Russia's refusal to use its pipeline Network companies needed an independent route to export oil that avoided Iran and Russia the tap EI project began with the signing of the inaugural memorandum of understanding between Turkmenistan and Pakistan in March 1995.   This project was first started by the brettis company through the promotion of the Argentinian company bredas but the American company unokal along with the Saudi Oil Co...

Egypt Is Building The World's Largest Artificial River In The Desert Imagine you are lost in the hot Western Egyptian desert thirsty and dying then suddenly something green appears on the horizon an oasis the size of a country an oasis that is not supposed to be there because your map from 2023 shows that this area is an arid desert that stretches for 200 kilometers in each direction that is exactly what Egypt is currently building to the southwest of Cairo a river like no other in the world the project is of epic proportions and will be accomplished over several phases the first is scheduled to be completed in 2025 at the most and will turn nearly 6 000 square kilometers of desert into one monstrous gigafarm that encompasses hundreds of kilometers of New Roads residential areas two power stations and the world's biggest wastewater treatment plant and the longest artificial River the second phase will be completed by 2030 at the most and double the size of the reclaimed ...
