An airport in the Netherlands has started operating the world’s first fully electric TaxiBot, which is designed to tow passenger aircraft from the gate to the runway while keeping their engines switched off.

Amsterdam Airport Schiphol, also known as Schiphol Airport, unveiled the system in May 2026, together with easyJet, Airbus, ground-handling company Menzies Aviation, and supplier Smart Airport Systems.

The electric TaxiBot is now transporting Airbus A320 aircraft to the Polderbaan Runway. This is the airport’s longest and newest runway, measuring 2.36 miles (3.8 kilometers). It is also the most distant runway and the one with the longest taxi times.

“By deploying the TaxiBot, we’re taking another practical step towards reduced emissions and noise on the apron,” Esmé Valk, Royal Schiphol Group people and transformation chief, revealed. This is how we’re creating a healthier and cleaner workplace, and an ever more sustainable and modern airport that is ready for the future.”

How TaxiBot works

The TaxiBot is a specialized tow vehicle that connects to an aircraft’s nose wheel and transports it across the airport at speeds of up to 23 knots (about 26 miles per hour, or 42 kilometers per hour). It can reduce fuel use by up to 65 percent before takeoff, while lowering emissions and noise.

In contrast to conventional airport tugs, the electric TaxiBot is controlled directly by the pilot from the cockpit. Meanwhile, aircraft engines remain off during the journey from the gate to the runway. They are once again started shortly before departure.

Once the aircraft reaches the runway, the TaxiBot disconnects. An operator drives the vehicle back to the terminal area to assist the next flight. “With TaxiBot, we are taking a tangible step towards making our operations at Schiphol more efficient,” William Vet, easyJet’s director for the Netherlands and Scandinavia, pointed out.

Schiphol selected the Polderbaan Runway for the rollout because it’s the runway with the longest taxi time. This can reduce fuel consumption by up to 65 percent. At the same time, lower fuel use also cuts carbon dioxide (CO2), nitrogen oxides (NOx), and (ultra)fine particle emissions.

Cleaner airport operations

Still, the aircraft tug does far more than just slash emissions. Reduced engine use means cleaner air for the employees working on the apron and lower exposure to pollutants generated by aircraft during ground operations. It additionally reduces noise levels and creates a more comfortable working environment around aircraft stands and service areas.

The electric TaxiBot joins two hybrid TaxiBots that have been towing KLM Boeing 737 aircraft to the same runway since 2022. It is being deployed on four of the Airbus A320neo aircraft, allowing engine-off taxiing to the runway.

“This immediately leads to lower fuel consumption, emissions, and ground noise,” Vet concluded in a press release. “This is only possible thanks to the commitment of our partners, and in particular the Menzies Aviation team, who play a crucial role in our ground operations.”

Schiphol currently runs the world’s only electric TaxiBot. The airport expects three additional electric units to arrive later this year. The expansion will allow the technology to support more aircraft types. Schiphol is also working with KLM Cityhopper and industry partners to certify the system for Embraer aircraft, while Transavia plans to participate with its Boeing 737 fleet.

China has officially started construction on a massive new ship lock system at the Three Gorges Dam, the world’s largest hydropower dam, which is set to nearly double cargo capacity along the Yangtze River.

Valued at USD 11.4 billion (CNY 77.2 billion), the project is considered the biggest infrastructure investment on the world’s third-longest river in decades. It includes the construction of a new five-stage ship lock system, often described as a “water staircase” or “water elevator.”

It will allow larger vessels to pass through the Three Gorges Dam more efficiently. The groundbreaking ceremony took place on Monday, June 8. The construction effort will take a total of 112 months, or about 9.3 years.

“The project will significantly improve efficiency for the implementation of the Yangtze River Economic Belt development strategy and support domestic economic circulation,” Liu Weiping, Three Gorges Group president and dam and future locks operator, said.

Expanding Yangtze capacity

The system will have a 22,000-foot-long (6,680-meter) two-way lock channel with five consecutive stages. It will moreover allow 11,000-US-ton (10,000-tonne) class vessels to pass through the dam more quickly and efficiently than before.

According to the South China Morning Post (SCMP), the initiative will also include wider approach channels upstream and downstream, along with new navigation facilities. Once completed, the novel facilities will raise annual cargo capacity at the Three Gorges Dam to 370 million US tons (336 million tonnes). That is nearly twice its current capacity.

The expansion is set to reduce transportation costs and boost logistics efficiency across the Yangtze River Economic Belt, the backbone of the nation’s economy. It generates more than 40 percent of the country’s total economic output. Spanning 11 provinces and municipalities, the river corridor supports almost 50 percent of the nation’s population.

“The old Three Gorges locks and ship lift have become a chokepoint,” Ministry of Transport representatives pointed out. “Even the boldest planning [decades ago] failed to anticipate the huge rise in passengers and cargo flows along the Yangtze today.”

Modernizing river transport infrastructure

The project has been included in the nation’s 15th Five-Year Plan (2026-2030). It forms part of a broader strategy to strengthen domestic transportation networks and support economic growth.

The Yangtze River has become increasingly important for manufacturers moving raw materials, industrial components, and finished goods between China’s coastal regions and inland provinces. However, rising river cruise traffic has placed extra strain on the existing navigation infrastructure.

Cargo volume passing through the existing locks first exceeded their 110 million-US-ton (100 million-tonne) design capacity in 2011. By 2025, annual throughput at the dam had climbed to 191 million US tons (173 million tonnes).

The new project represents the largest infrastructure effort on the Yangtze River in decades. It surpasses the scale of any major work undertaken since the Three Gorges Dam began operating in 2003.

Officials said the expansion has become necessary as growing shipping demand continues to strain the existing facilities. The development aims to strengthen the Yangtze River’s role as a crucial transport route.

China has successfully tested a huge airborne electromagnetic detection system that could locate hidden nuclear submarines operating deep beneath the ocean surface.

The technology, called Airborne Transient Electromagnetic (Atem) detection, is reportedly made up of a helicopter towing a giant array of coils. The coils emit strong electromagnetic signals into the ground or water.

It is mainly intended to map underground and underwater structures for civilian applications, such as mineral exploration, groundwater mapping, and geological surveys. Previous studies, however, suggest the same approach could have great military potential.

Led by Fu Jingcheng, PhD, an associate professor at Beihang University and the Chinese Academy of Sciences’ Institute of Geology and Geophysics, the research team carried out a seven-minute helicopter test. During the trial, onboard sensors confirmed that the coil array could maintain the near-level stability required for precision detection.

A new detection tool

The South China Morning Post (SCMP) pointed out that the detection system is a towering structure that consists of three giant dodecagonal (12-sided) coils. Each of them measures roughly 82 feet (25 meters) across. These coils serve as the transmitter, compensation unit, and receiver.

They are suspended under a helicopter using a network of cables. The technology sends a powerful pulse of electricity through the transmitter coil. This generates a brief electromagnetic field.

Once the pulse ends, conductive materials below the surface produce secondary electromagnetic signals that are captured by the receiver coil. By analyzing how these signals decay, scientists can identify buried or submerged objects and also estimate their depth and composition.

However, maintaining stability during flight is one of the greatest limitations of airborne electromagnetic systems. Large suspended coil arrays can tilt and swing due to wind, helicopter rotor wash, and aircraft maneuvers. These movements can affect the accuracy of the collected data. Even moderate helicopter acceleration caused the massive structure to pitch by more than 20 degrees.

Overcoming the challenges

To overcome these issues, Jingcheng and his team developed a computer model that calculated the ideal cable lengths and tensions throughout the system. They then identified a flight configuration that kept the coils level during surveys.

What’s more, the researchers also attached a flexible aerodynamic film to the rear portion of the main transmitter coil. This film works as a passive stabilizer. It can suppress violent oscillations by exerting a restoring force.

A seven-minute flight confirmed the design’s ability to maintain the near-level orientation required for precision measurements. The trial also showed that rapid acceleration and sharp turns can cause the suspended load to swing violently, placing heavy strain on the cable.

The researchers noted that the detection system performs best when flown slowly and smoothly. Pilots should reduce speed before a turn, make the turn gradually, and only speed up afterward.

A 2012 study by researchers from Chang’an University and Shandong University proposed combining Atem systems with synthetic aperture imaging techniques to detect submerged submarines. Simulation experiments reportedly succeeded in identifying a scaled submarine model submerged in salt water.

The study has been published in the journal Acta Aeronautica et Astronautica Sinica on April 25.
