23 Giant Concrete Caissons Now Form the Foundation of Belgium’s Artificial Energy Island

Belgium has completed the foundation structure of the Princess Elisabeth Energy Island, being built about 45 kilometres offshore in the North Sea. All 23 enormous concrete caissons are now installed, forming the protective outer shell of the future island. Each weighs around 22,000 tonnes and is up to 32 metres high.

The next stage is to fill the structure with millions of cubic metres of sand and build the island’s electrical infrastructure. Its initial HVAC system is designed to bring up to 2.1 GW of offshore wind power to Belgium’s mainland, making the island a major hub for the country’s expanding North Sea wind industry.

The project is also being designed with marine biodiversity in mind, including new oyster reefs around the structure. Final completion is planned for 2031. While the original concept included both HVAC and HVDC technology, the HVDC component has been postponed, so the island’s final configuration is still evolving.

Thousands of retired wind turbine blades in the United States are finding a second life inside cement plants instead of simply being discarded.

 

Thousands of retired wind turbine blades in the United States are finding a second life inside cement plants instead of simply being discarded.

A recycling program launched by GE Renewable Energy and Veolia North America in 2020 processes decommissioned turbine blades so their composite material can be reused in cement production. The blades are cut down and shredded at a Veolia facility in Missouri, creating material that can replace part of the sand, clay and other raw ingredients normally used to make cement. Some of the polymer content can also provide energy inside the kiln, reducing the need for conventional fuel. Veolia says more than 90% of a blade’s weight can be put to use through this process. Recent reports say the program has handled more than 7,000 blades since it began, showing how one of wind energy’s most difficult end-of-life materials can be redirected into another major industry.

saudi researchers at king abdullah university develops the technology uses ammonium nitrate dissolved in water to cool down temperature from about 25°c to around 3.6°c in roughly 20 minutes.

 

saudi researchers at king abdullah university of science and technology (kaust) have developed an experimental cooling system called nescod, short for “no electricity and sustainable cooling on demand.” unlike conventional refrigerators and air conditioners, the system does not require a compressor or continuous electricity during its cooling phase.

the technology uses ammonium nitrate dissolved in water. when the salt dissolves, the process absorbs heat from its surroundings, creating a powerful cooling effect. in laboratory testing, the system reportedly lowered the temperature from about 25°c to around 3.6°c in roughly 20 minutes.

what makes the concept especially interesting is that the system can be regenerated using sunlight. solar energy helps remove the water from the salt solution, allowing the ammonium nitrate to be recovered and reused for another cooling cycle. this creates a potentially low-energy approach to cooling that could be useful in hot regions and places where reliable electricity is limited.

however, this is still an experimental technology, not a replacement for household refrigerators or air conditioners today. researchers are exploring how systems like nescod could eventually support food preservation, off-grid cooling, and other applications where electricity is expensive or unavailable. if developed further, the combination of chemistry and solar energy could offer a fascinating new way to stay cool without relying on conventional power-hungry systems.

August 24, 2001. 06:26 UTC. Both engines failed over the Atlantic Ocean. The Airbus A330 had no power. The aircraft was 65 nautical miles from Lajes Air Base in the Azores.

 

August 24, 2001. 06:26 UTC. Both engines failed over the Atlantic Ocean. The Airbus A330 had no power. The aircraft was 65 nautical miles from Lajes Air Base in the Azores.

Captain Robert Piché, 48, had 16,800 flight hours. 796 hours on the Airbus A330. He was an experienced glider pilot. He learned to fly as a teenager in Quebec's Gaspé Peninsula.

First Officer Dirk DeJager, 28, had 4,800 flight hours. 386 hours on the A330.

When engine number 1 flamed out, Piché took control of the powerless aircraft. DeJager calculated descent rate: approximately 2,000 feet per minute. He calculated fuel reserves and altitude. He determined they had 15 to 20 minutes to reach the air base or ditch in the ocean.

Air traffic control guided them toward Lajes. Piché had to execute 360-degree turns to lose altitude and speed while maintaining glide path toward the runway. The aircraft descended through 20,000 feet. Then 10,000 feet.

The runway came into view. But the aircraft was descending faster than optimal. The airspeed was too high.

Piché executed a forward slip maneuver—banking the aircraft while holding the nose level. This increased drag and slowed the descent without changing pitch. It was a precision maneuver in a powerless aircraft with 306 people aboard.

DeJager monitored the descent continuously. His calculations kept them on glide path.

Piché lined up with runway 33. The aircraft touched down at 06:45 UTC. Landing speed: approximately 200 knots.

The glide lasted 19 minutes over 65 nautical miles. The longest glide of a commercial passenger aircraft without engine power.

All 306 people survived. 18 sustained injuries. No fatalities.

Captain Piché's gliding experience. First Officer DeJager's precision calculations. Two pilots. No engines. Perfect execution.

The World's Largest Electric Plane Heart Aerospace's X1Just Flew... And It Cost Just $5 in Electricity for 27 minutes, On August 12, 2026

 

The World's Largest Electric Plane Just Flew... And It Cost Just $5 in Electricity

On August 12, 2026, something remarkable happened in the skies above upstate New York. Heart Aerospace's X1 demonstrator aircraft took off from Plattsburgh International Airport and flew for 27 minutes, reaching an altitude of 1,100 feet, powered entirely by batteries. No jet fuel. No emissions. Just electricity.

And here's the number that stopped everyone in their tracks: the entire flight cost roughly $5 in electricity.

Let that sink in. This isn't a toy drone or a small experimental glider. The X1 has a wingspan of 106 feet, stretches 76 feet from nose to tail, and weighs more than 25,000 pounds at takeoff, making it officially the largest battery-electric aircraft to ever fly. During the test, its all-electric propulsion system delivered more than one megawatt of power, all while taxiing, climbing, maneuvering, and landing under a special FAA airworthiness certificate.

For comparison, a conventional regional jet covering the same 27 minutes would burn through roughly $400 worth of jet fuel. Heart Aerospace timed this milestone against a backdrop of surging fuel prices, which have climbed 63 percent over the past year, and the contrast could not be more striking.

The X1 itself will never carry passengers. It exists purely as a proving ground, a full-scale demonstrator built to validate the technology, aerodynamics, and engineering behind Heart's real commercial product: the ES-30, a 30-seat hybrid-electric regional airliner targeted for service in 2031. Unlike the X1, the ES-30 will pair batteries with a combustion range extender, offering roughly 125 miles on electric power alone and up to 500 miles combined.

The industry is already paying attention. Heart Aerospace has secured a staggering 9.4 billion dollars in customer commitments from major carriers including United Airlines, Air Canada, and JSX, with United alone holding 100 aircraft orders. United's CFO Michael Leskinen called it a major technical achievement, while Air Canada, which has also made a direct equity investment in the company, framed it as one piece of a much larger energy transition for aviation.

Of course, the five dollar figure only tells part of the story. It reflects energy costs alone and does not account for crew pay, landing fees, insurance, or long term battery wear. Still, as a glimpse into what the future of regional air travel could look like, this flight is nothing short of historic.

Japanese designer and engineer Satoshi Nakagawa has developed a technology called Micropower Collection (MPC) that extracts tiny amounts of electricity from natural materials such as soil, compost and water.

 

Japanese designer and engineer Satoshi Nakagawa has developed a technology called Micropower Collection (MPC) that extracts tiny amounts of electricity from natural materials such as soil, compost and water. The approach uses electrodes to collect small electrical currents from materials containing moisture and ions.

His KU-AN experimental facility in Japan demonstrates the concept using around 1,500 soil-based collector cells. The installation can continuously generate enough low-level electricity to illuminate hundreds of LEDs, showing how tiny energy sources can be combined for useful applications.

Nakagawa believes MPC could be useful in off-grid locations and disaster zones, where conventional electricity infrastructure is unavailable. Potential applications include environmental sensors, flood and landslide monitoring, agricultural devices, communication equipment and small lighting systems.

The technology is fundamentally different from conventional power generation because it is designed for micropower rather than large-scale electricity production. Its advantage is continuous energy harvesting that does not depend on sunlight, wind or a particular time of day, according to its developers.

However, engineers have questioned its practicality because the electrical output is far lower than conventional batteries. MPC is therefore better viewed as an emerging energy-harvesting technology for low-power devices rather than a replacement for solar, wind or grid-scale generation.
