Startup Launches Ecological System Supported by CNRS and Challenges Traditional Air Conditioning with Unprecedented Electricity Savings

An innovation created in 2020 by the French startup Caeli Energi promises to transform the way people cool environments.
The equipment, developed with the support of the French National Centre for Scientific Research (CNRS), consumes five times less energy and offers four times more thermal efficiency than conventional units.
Moreover, the proposal arises amidst rising temperatures and the search for cleaner, more economical, and sustainable solutions for thermal comfort.

Energy Efficiency and Reduced Environmental Impact

Since its founding, Caeli Energi has been working to solve two major problems of modern air conditioning: high electricity consumption and environmental impact.
To this end, the company invested in research between 2021 and 2024, focusing on energy efficiency and sustainability.
The result was a high-performance and low environmental impact system capable of maintaining a stable temperature with minimal energy expenditure.

According to the startup, tests conducted in March 2025 confirmed significant reductions in energy bills and constant thermal comfort. Thus, the product becomes especially attractive for hot climate countries, such as Brazil, where electricity consumption rises during the summer.

Innovative Design and Superior Performance

The model features an oval shape and a height of 2.5 meters, which deviates from the standard of conventional air conditioners. Still, the futuristic design and superior efficiency attract the attention of engineers and consumers.

Additionally, the system was designed to combine elegance, performance, and sustainability, the company stated to the newspaper Le Monde in August 2025. The price ranges from € 2,500 to € 3,000, equivalent to R$ 13,500 to R$ 16,000.

Despite the high cost, Caeli Energi assures that the investment pays off over time. This is because the low electricity consumption generates continuous savings. With this, consumers reduce spending and help lower polluting emissions.

Global Trend of Sustainable Solutions

The global climate crisis, exacerbated since 2022, drives the development of sustainable technologies. In this context, the system from Caeli Energi stands out as a relevant advancement. The support from CNRS reinforces the scientific credibility of the project and the importance of investing in solutions that combine efficiency and environmental responsibility.

According to CNRS, the main objective of the partnership is to reconcile thermal comfort and environmental sustainability. Therefore, the startup believes that its technology can mark a new era in global air conditioning, where efficiency and environmental awareness go hand in hand.

International Expansion and Promising Future

Caeli Energi plans to expand production by 2026, prioritizing hot climate markets such as Brazil, India, and Australia. According to European experts, the equipment has the potential to replace traditional air conditioning and reduce global energy consumption.

Thus, the French technology proves that it is possible to unite savings, innovation, and sustainability in a single product. In addition, the company aims for continuous growth and the consolidation of France as a reference in green air conditioning.

International Expansion and Promising Future

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Great Atlantic Sargassum Belt has ceased to be a climatic phenomenon and has become a biological system that feeds on itself, with 8,000 kilometers in length, 37 million tons of algae, and scientists confirm that it is now permanent.

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.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

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 James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

Air bubbles from 3 million years ago extracted from Antarctic ice reveal that the current level of CO₂ has already surpassed that of the ancient, warm world, when the sea was up to 20 meters higher and there were no factories or cars burning fuel.

Brazil went to China to seek money and technology to reinvent TV and bring the internet to places where fiber does not reach. The mission negotiated with the BRICS Bank led by Dilma and paved the way for a Chinese rival of Starlink to connect the Amazon.

About 150 workers are driving, one by one, 4,585 BYD electric cars off a 220-meter ship at the Port of Itajaí. The 48-hour mega-operation is the largest shipment from the Chinese automaker in Santa Catarina this year.

Iceland is going to lower a drill five kilometers to reach rock at 400 degrees and try to extract clean energy on a scale that a common well cannot achieve.
