The British-American company ZeroAvia is one of the aviation companies that is investing in the development of fuel cell propulsion systems for aircraft. And following receiving approval from a British official to go ahead with the technology, a short video was released featuring the first test flight of a Dornier 228, a 19-seat aircraft modified to use its new electric motor powered by a hydrogen fuel cell system.

The test’s success, which can be seen in the video below, is another step in the race to develop more sustainable air transport.

The aircraft took off at the company’s research and development facility at Cotswold Airport in the UK and flew overhead for 10 minutes. The test was part of the HyFlyer II project, supported by the Aerospace Technology Institute (ATI), a British government entity, which seeks to create a zero-emission propulsion system for aircraft with a capacity of 9 to 19 passengers.

The twin-engine was adapted to incorporate ZeroAvia’s powertrain, while the 600 kW electric motor was placed only on the left wing to ensure safety. On the right was the Honeywell TPE-331 series engine.

The electric motor, in addition to the fuel cells, was powered by a battery that provided energy at times of maximum power demand, such as during takeoff. In this test configuration, the hydrogen tanks and fuel cells were housed inside the cabin — a configuration that will change for future commercial flights.

The idea is to carry out more tests to ensure the safety and operation of the operation so that this type of flight begins to enter the commercial scale from 2025.

Some people heard a loud noise and saw an unusual sight in the skies over Oklahoma early Friday morning.

Michael Armstrong, KOCO 5 meteorologist, said the fireball flew over Oklahoma around 3:40 a.m. east of Tulsa. However, the fireball was seen in several areas across the state, including metro Oklahoma City.

The fireball exploded in the atmosphere, creating a sonic boom that turned it into a thunderbolt – a large meteor exploding in the atmosphere.

Share some fireball videos with KOCO 5. Jake Byard’s camera on the doorbell caught the fireball from Prague, and Trevor Wynn’s camera viewed it from the Yukon.

Last Wednesday, a journalist shared an excerpt from the book “Four Battlegrounds: Power in the Age of Artificial Intelligence” by Paul Scharre, and those who have played the “Metal Gear Solid” series may feel called out.

In the excerpt shared by Shashank Joshi from The Economistthe author of the book explains in detail how several American Marines managed to deceive a targeting system equipped with artificial intelligence.

Eight Marines had the task of fooling the AI ​​using different non-traditional camouflage methods. Among these valiant soldiers, two Marines hid under a cardboard box.

Does that remind you of something? Yes yes! They used the surefire method Snake used in several of the franchise’s titles. Metal Gear.

“You might hear them laughing all the time. Like Bugs Bunny in a cartoon Looney Tunes, sneaking towards Elmer Fudd in a cardboard box,” the excerpt read. Thanks to this technique, the AI ​​never detected the two hidden Marines. Having been with these soldiers, we would have laughed just as much during this exercise.

Another proof that video games can be used in everyday life. Hats off to his brave Marines!

During the next night, it would be possible to see the aurora borealis, caused by a solar storm less than a week ago at 150 million km from planet Earth.

The phenomenon of the aurora borealis might also become more and more frequent over the next two years, according to Olivier Hernandez, director of the Planétarium Rio Tinto Alcan.
