Handful of gas plants paid £4m to generate electricity at half- and full-time in World Cup game

A handful of Great Britain’s gas power plants were paid almost £4m to generate electricity for just a few hours on Tuesday evening as millions of sweltering viewers turned to air conditioning, electric fans and icy drinks during England’s second World Cup game.

The heatwave has caused electricity prices across Europe to surge this week amid higher demand for cooling and a string of power plant outages due to the record high temperatures.

Researchers at the Massachusetts Institute of Technology (MIT) have developed an ultra-efficient computer chip that could help tiny robots and lightweight devices create detailed 3D maps of their surroundings while using very little energy. The new chip could allow small drones to fly through narrow spaces, such as air-conditioning ducts or industrial pipelines, to inspect […]

For our weary eyeballs, strained and tired from long periods locked onto screens, rest and relaxation can do wonders. But a man in Scotland came up with an eye-popping plan to try to pamper his pooped peepers.

Ophthalmologists discovered it when the man, who was in his 20s, appeared at an eye treatment center in Edinburgh. He told them he had noticed increasing floaters and flashing lights in his right eye over the previous six days. According to a BMJ Case Report, the man said he hadn't had any eye or head injuries before the vision problems began, and that his family didn't have a history of eye disorders that might explain them. Besides having mild near-sightedness and needing glasses, he usually didn't have any problems with his eyes, he said.

When the doctors—Niamh O’Connell ‍‍and Ashraf Khan—took a close look, they were surprised to find that both of his eyes were in terrible shape. In his right eye, he had multiple retinal tears, widespread retinal bruising, and a condition called retinal dialysis—a retinal break at a junction in the front of the eye—that is usually seen after a significant eye injury. In his left eye, he had more widespread bruising and six full-thickness rips in his retina.

Electric Vertical Take-Off and Landing (eVTOL) pioneer Archer Aviation has confirmed that it is on track to perform Team USA transport duty during the 2028 Summer Olympics in Los Angeles, California, aboard its Midnight aircraft.

In an email to The Debrief, a company spokesperson said Archer was selected as the Official Air Taxi Provider of the LA28 Olympic Games and Team USA, marking a historic first in the quest for commercial eVTOL operations before the end of the decade.

“Through this exclusive partnership, the two will look to integrate Archer’s Midnight eVTOL aircraft across theLA28 Games in a variety of ways, such as transporting VIPs, fans, and stakeholders, while electrifying vertiport take-off-and-landing hubs for key venues and providing support for emergency services and security,” a company spokesperson explained.

Archer CEO Announces ‘Progress’ Including Upcoming Midnight eVTOL Test Flight in 8 US Cities

Archer Aviation founder and CEO Adam Goldstein recently shared more specific updates about the company’s road to the Olympics and eventually government approval, noting that “we made tremendous progress towards beginning operations in the US later this year, with record FAA certification progress and our most expansive flight testing to date.”

Goldstein also highlighted the company’s recent winning applications to begin pre-certification test flights of Midnight in 8 US states later this year, including New York, Florida, and Texas. According to the CEO, those test flights are part of the eVTOL Integration Pilot Program (eIPP), “which was unlocked through the White House’s Executive Order in June last year.”

“Archer expects Midnight operations in American cities to begin this year as part of the White House’s eIPP and in preparation to serve as the Official Air Taxi Provider of the LA28 Olympic Games, in coordination with the DOT and FAA,” the CEO explained, adding that the two benchmarks “pave the way for Archer to showcase its air taxi technology in parallel with its continued work toward FAA Type Certification for Midnight.”

Six Independently Operating Engines Produce Over 1,500 Horsepower, Last 10,000 Flight Cycles

When asked about the technical aspects that have put Midnight on course to become the first commercial eVTOL air taxi provider in the U.S., the company spokesperson first noted that their aircraft are “designed and manufactured” domestically, which can shorten development timelines and improve quality control. This includes focusing the team’s research and development on what the company termed “differentiating technologies,” including the pioneering aircraft’s unique powertrain.

“Our world-class in-house team, coming with experience from Apple, Tesla, SpaceX and beyond, contribute to our efficient and certifiable electric propulsion design,” the company told The Debrief.

Some of the differentiating technologies the team said set it apart from the competition include rapid charging, long-lasting battery packs “and the capability of >1500 horsepower.” They also note that Midnight’s high-performance battery cells, patented high-voltage architecture, and gearbox are designed to operate reliably for roughly 10,000 “flight cycles” before the vehicle’s battery pack needs replacement.

“We are optimized for electric flight,” the company told The Debrief.

Due to the potential risks in premiering a new vehicle platform, with Archer Aviation telling The Debrief that “eVTOL aircraft are the first new category of aviation in more than 60 years,” the company said Midnight is built as a ‘fly-by-wire’ system, reducing the number of mechanical components that can fail. The company also said that each of Midnight’s engines operates independently “allowing for high levels of redundancy and safety.”

Although the current version of the Midnight eVTOL aircraft is flown by a human pilot, the company told The Debrief that it is “continuing to build the technology stack” required for its longer-term goal of a fully autonomous eVTOL aircraft.

Company Anticipating Final FAA Approval “in the Near Future”

With the 2028 Summer Olympics just two years away, the company said it has transitioned out of a successful Phase 3 of the FAA’s 4-phase Type Certification process, an industry first, and has “already been advancing its work in Phase 4 for some time now.”

“This is where Midnight’s compliance with FAA airworthiness requirements will be demonstrated through formal testing and analysis,” the company told The Debrief.

In his address to shareholders, Goldstein said the company’s flight test program “continued to expand this quarter.” The CEO said this expansion includes piloted VTOL and CTOL flights across its expanded fleet of test aircraft “occurring nearly every day, often multiple times a day.”

To expedite the testing phases leading up to the 2028 Olympics, the company recently took over operations of Hawthorne Airport in Los Angeles County. Goldstein said the move will help Archer develop the local airstrip “into the airport of the future.”

“Located near LAX and several major LA sports and entertainment venues, Hawthorne Airport is expected to anchor Archer’s planned LA air taxi operations while also serving as an innovation hub for next-generation aviation technologies,” the CEO explained.

When asked how soon the company expects to fulfill the FAA’s Phase 4 requirements and gain full certification, the spokesperson told The Debrief that Archer is in the final stages of the process, “and is anticipating approval in the near future.” However, the company also added that their focus is on building a safe, high-performance aircraft, and that once they can demonstrate the safety and versatility of Midnight, “it is the FAA’s job to certify it.”
