Solar energy is one of the most promising sources of renewable energy, but faces challenges like shading caused by clouds, trees, and buildings. However, photovoltaic balloons emerge as an innovative solution to overcome these obstacles.

Traditional solar panels suffer significant losses in efficiency due to shading. Even a small cloud can reduce energy generation, and on rainy days, production drops drastically.

Cool Earth Solar has developed a revolutionary technology: photovoltaic balloons. These balloons float about 20 km above the ground, where there are no clouds, ensuring continuous and direct exposure to sunlight.

Photovoltaic balloons are kept in the air by cables connected to the ground, which also serve to transmit the energy generated back to the Earth

They use photovoltaic cells to capture sunlight and convert it into electricity. Operating above the clouds, these balloons eliminate shading losses, ensuring maximum efficiency. Sunlight is more intense at 20 km altitude, resulting in energy production five times greater than at ground level.

Each photovoltaic balloon can generate up to 500 watts of energy

The absence of sunlight diffusion through the atmosphere at this altitude significantly increases the yield of solar cells. Currently, the technology is in the experimental phase but already shows great viability. Researchers are working to overcome technical and regulatory challenges, aiming for large-scale commercialization.

Photovoltaic balloons represent a major innovation in the field of solar energy. They not only provide a solution to the shading problem but also enhance energy generation efficiency. With the energy transition underway globally, technologies like this are essential for a more sustainable future.

Certo. E como ficam a circulação de aviões e drones ? Eles vão ter que ficar desviando destes cabos e balões?

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

Engineers had to pour concrete mixed with tons of ice throughout entire nights in the Dubai desert to erect the Burj Khalifa; any carelessness could clog the pipes half a mile high.

The battery that uses the cold night sky to generate electricity: scientists create a device that transforms heat escaping from the Earth into energy, even without sun, wind, or combustion.

James Webb finds a starless world with a rotation of only 2.4 hours, giant clouds of superheated sand, and auroras that heat the atmosphere to over 1,500 °C; a wandering object 20 light-years from Earth challenges even the definition of what a planet is.

Study reveals that El Niño is gaining strength in the Pacific, favoring the soybean crop in the United States in 2026 and increasing the risk of losses in Brazil due to excessive rainfall in the South and drought in the Midwest, a scenario that could affect global prices and agricultural exports.

The atmosphere of Venus is so dense that it managed to reverse the entire rotation of the planet over billions of years, a study published in Nature Astronomy reveals that being on the surface would be like sinking into an ocean of 475 degrees Celsius.

Government announces more than R$ 7 billion in investments in Amazonas on a single Wednesday, the package includes a controversial highway, energy for 75,000 people in communities, new ports, and the largest order in the Brazilian naval industry in a year.
