Salar de Uyuni: Getting to Know the Largest Salt Desert in the World in Detail

During the rainy season (December to April), the Salar de Uyuni transforms. It becomes “the largest mirror in the world”. A thin layer of water covers the salt flat, creating an almost perfect reflective surface. The sky, clouds, and stars are duplicated with impressive clarity.

The science behind it is fascinating. The rainwater accumulates on the impermeable salt crust. For the perfect reflection, a calm day with no wind is required. The extraordinary flatness of the Salar is equally crucial. March and April are noted as months with the highest likelihood of witnessing the effect. Experiencing this spectacle involves an element of luck, making it even more special.

Wonders of the Salar de Uyuni and Surroundings

Exploring the Salar de Uyuni and its surroundings reveals surreal landscapes:

Train Cemetery: In the vicinity of the city of Uyuni, dozens of abandoned steam locomotives from the 19th and 20th centuries create a melancholic and photogenic sight.

Sol de Mañana Geysers: A geothermal field at 4,850 meters above sea level, with fumaroles, bubbling mud, and a strong sulfur smell.

Colored Lagoons: The Laguna Colorada (red) and Laguna Verde (emerald) are famous for their vibrant hues, due to minerals and algae, and for hosting flamingos.

Salt Hotels: A unique experience is staying overnight in hotels built almost entirely with salt blocks extracted from the Salar.

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

Elon Musk’s internet comes to mobile: Starlink technology connects smartphones without an antenna via satellite, works even without carrier signal, already costs just US$10 extra in the US, and could arrive in Brazil as an included benefit.

While Brazil has been discussing bullet trains for 16 years, China delivers 5 new high-speed lines in 2026, surpasses 50,000 km of HSR, and moves 1 billion passengers in a single year.

With a wingspan of 152 meters, 76 tires, and a capacity to carry 1,270 tons, the Boeing Pelican was the giant “flying ship” that promised to cross oceans close to the water on an invisible air cushion beneath its wings.

While countries spend billions to draw water from the sea, a Nobel-winning scientist creates a container-sized machine that extracts up to 1,000 liters per day from dry air and uses ultrasound to release water in minutes, even in the middle of the desert.

Belgium will sink 23 giant concrete caissons, each weighing 22,000 tons, in the North Sea to build the world’s first artificial energy island 45 km off the coast, forming offshore electrical walls.

A 33-year-old Paranaense practically built a two-story, 200-square-meter house by himself, without ever having had experience in civil construction, engineering, or architecture.

Unclaimed funds will enter a new phase this Tuesday: banks must send funds to the government, while R$ 10.5 billion in idle funds could help finance Desenrola 2.0 and ensure debt renegotiation within the financial system.

How much is spent on a 100 m² foundation becomes a warning for those planning to build, using concrete, steel, and wood.

Scientists make worrying discovery: New study reveals that airborne microplastics can worsen global warming on a scale comparable to that of 200 coal power plants spread across the planet.

Egypt will reveal a 4,500-year-old secret by opening a sealed secret chamber inside the Great Pyramid and promises to unveil a mystery that intrigues the world.
