To build this dam, engineers first drowned a waterfall twice the size of Niagara. You could hear it roaring from 20 miles away. Then they made one of the world's biggest rivers move out of the way, just to clear room for the construction site.It's the Itaipu Dam, on the Paraná River where Brazil meets Paraguay. Work started in 1975, and the first job was the river itself. Crews spent three years carving a 1.2-mile channel through solid bedrock, 500 feet wide and 300 feet deep.They hauled away 50

🇯🇵 Japan is spending $67B to build a high-speed train that floats.The Chuo Shinkansen Maglev line will get you from Tokyo to Osaka faster than a flight will (door-to-door) at up to 375 mph.They have wheels like other trains do, but magnetic levitation lifts them off the track entirely, eliminating friction and noise simultaneously.The ultimate challenge lies in the terrain. Because the route cuts straight through the Japanese Alps, nearly 90% of the line will run deep underground.To make a tra

how do you even achieve this build

The 44-storey 88 Nairobi has been under construction for 10 plus years. I have seen China build a taller building (57 storeys) in 19 days

APPLE JUST GOT HUMILIATED BY AN $8 JACKET BADGEA random Japanese maker saw Apple's $3,499 Vision Pro Persona and decided to build the same thing for the price of a pizza.Same real-time face mirroring. Same natural expressions and blinks.
