as demand for air travel continues to grow and with the United States preparing to host both the 2026 FIFA World Cup and the 2028 Olympics, airports across the country , from Laguardia to Lax, are undergoing multi-million dollar renovations. The $1 billion upgrade of Chicago O'Hare International Airport will mark the first comprehensive redevelopment and expansion of the terminal core in the airport's history.

The master plan will see the expansion of Terminal 5, while Terminal 2 will be completely rebuilt and converted into a global transfer center with two satellite concourses. adding 280,000 square meters of space and 50 additional gates to the airport to minimize disruption, the new concourses will be built first, allowing them to take over Terminal 2 operations when the existing building is demolished, works on the terminal 5 are scheduled to be completed in 2022 and subsequent phases will open in stages until 2028. A joint project between 35 nations. The ITER, formerly known as the International Thermonuclear Experimental Reactor, is currently under construction in France. Once completed, the $20 billion center will allow scientists to recreate the fusion reactions that take place.

Inside the sun that potentially revolutionizes energy production Consisting of three main buildings The product is centered around the tokamak, a magnetic chamber that will contain the plasma created when particles are heated to more than 150 million degrees Celsius and collide to produce energy Fusion construction of the vast building housing the reactor began in 2013, requiring the development of 10 different types of concrete to protect workers from radiation; More than 60 percent of the reactor complex is now complete. Work is now underway on the tokamak within its 337,000-tonne accommodation chamber, the entire complex is due to come into operation in 2025.

in Africa whose works began in 2011 the dam will become the largest hydroelectric plant on the continent, generating about 6.45 gigawatts of energy when it will be completed in 2022, it will have a height of 155 meters and It will extend almost 1,800 meters along the Blue Nile.

The main structure is being formed from more than 10 million tonnes of concrete that will retain 74 cubic kilometers of water when the reservoir is full, while the dam will transform Ethiopia's energy. Production The project has been marred by controversy since its inception 20,000 people were relocated to allow for construction work and many have expressed concern about the project's price tag of US$4.8 billion, which represents approximately six percent of GDP Ethiopia's total and saw funds diverted from other much-needed energy projects: The dam has also reignited an ongoing dispute between Ethiopia and downstream nations Sudan and Egypt, which view the project as an attempt by the Ethiopian government to win regional influence since its first bullet train hit the world stage in 1964.

Japan has been a pioneer in the development of high-speed rail, while competition from Europe and China has seen the title of the world's fastest trains shift towards the West in recent years. The new Chao Shinkansen, with its Maglev cars capable of reaching speeds of 500 kilometers per hour, will allow Japan to recover. title despite the fact that Tokyo and Nagoa are separated by 284 kilometers, the new line will bring the two cities closer to within 40 minutes of each other and will become one of the shortest routes on the shinkansen network. 90 of the route will run underground and under the Japanese Alps, reducing the travel distance of more than 50 kilometers and saving $4.9 billion compared to alternative options.

The new line will open in 2027. Plans are already underway for an extension linking Nagowa to Saka. A $30.5 billion mecca project rising 271 meters above Sydney. emerging barangaroo district the 75-storey one barangaroo, also known as Crown Sydney, will become the city's tallest building designed by Wilkinson Air. The structural form of the tower is based on three twisted petals and will contain a casino, Australia's first six-star hotel and 82 luxury apartments overlooking the famous harbor whose shape ensures that no two rooms are alike. The tower is clad with more of seven thousand unique triangle-shaped panels that give it a crystalline appearance as it rises the complex will offer extreme luxury with a spa, gym, outdoor tennis court, two rooftop infinity pools and a Michelin-star restaurant that will culminate in November 2019 and scheduled to open in 2021, one barangaroo is already making its mark on the city's skyline.
