Mercedes Tests Solar Paint That Transforms Light Into Energy And Can Extend The Range Of Electric Cars By Up To 40 Km Per Day

Mercedes-Benz is betting on a new technology to improve the range of electric cars. This is “solar paint,” an ultra-thin photovoltaic layer that can transform sunlight into electric energy. The proposal is to use this innovation as a complementary charging source for the vehicles.

The technology is still in testing phases, but it is already drawing attention. The application took place in Beijing, China, where initial analysis demonstrated that the solar paint can add up to 40 extra kilometers per day to the range of a car when exposed to sunlight under ideal conditions.

According to data from Mercedes-Benz, this can represent over 14,000 extra kilometers per year. The energy generated by the paint is stored directly in the vehicle’s batteries, increasing the time of use between charges.

High Energy Efficiency

The most important aspect of this new solution is its efficiency. The photovoltaic layer can capture up to 94% of sunlight.

This high conversion rate is impressive and highlights the technology compared to other similar attempts in the past.

The solar paint is applied over the traditional paint of the cars without altering the appearance or available colors.

The aesthetics are maintained. This means consumers will not have to give up style for greater energy efficiency.

Mercedes-Benz has made it clear that this technology does not replace conventional charging. It serves as an additional source of clean energy.

Therefore, it remains necessary to charge electric cars at regular stations. However, with solar paint, the range can be extended in a practical and sustainable way.

Focus on Sustainability

In addition to solar paint, the German company is developing other sustainable solutions. One of them is a more durable brake system.

According to the automaker, the new model will be corrosion-resistant and will require less maintenance. This can reduce costs for the owner and decrease waste production over the vehicle’s lifespan.

These initiatives demonstrate Mercedes-Benz’s commitment to innovation and the pursuit of eco-friendly alternatives.

The expectation is that these technologies will help the automotive sector move toward a more sustainable future.

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.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

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.

Researchers are excavating in Morocco the world’s oldest ankylosaur, dating back 165 million years, with nearly 1-meter long spines protruding from its neck.

Russia is sailing all 8 nuclear icebreakers of its fleet simultaneously for the first time in history, as the Arctic freezes two weeks earlier than expected.

Few know, but India has a 36 km wall that surrounds a fort in the mountains and is considered the second largest in the world, behind the Great Wall of China.

Hyundai Creta 2029 appears in new spy shots with a completely revamped design, a more modern digital interior, a larger multimedia center, a more comfortable passenger seat, and electrification finally on the radar.

Former CIA analyst warns that China has already surpassed the US in missiles, electronic warfare, cyber, and military production, transforming the Pacific into a zone without safe spaces while Washington clings to its submarine advantage.
