The biggest battleground in the robotaxi race may be winning public trust.


Autonomous vehicles are already clocking up millions of miles on public roads, but they face an uphill battle to convince people to climb in to enjoy the ride.

A few weeks ago, I took a tour of San Francisco in one of Waymo’s self-driving cars. As we drove around the city, one thing that struck me was how comfortable people had become with not seeing a driver. Not only were there multiple driverless vehicles on any given street at any given time, but tourists no longer had their mouths agape as one drove by. The technology has become a familiar sight.

Inside the vehicle itself, there were signs of how Waymo is trying to inspire a similar feeling among their passengers. The all-electric car offers a warm welcome to passengers by name and plays music as they climb inside. A screen positioned in front of the rear seats offers those along for the ride the option of seeing a follow-along map of the route, as well as settings for temperature and music. Another screen beside the steering wheel shows images of what’s around the vehicle. As we drive, I can see people sitting inside buses alongside us, dogs crossing the street ahead and children skipping along the sidewalk.

Team develops simulation algorithms for safer, greener, and more aerodynamic aircraft.


Ice buildup on aircraft wings and fuselage occurs when atmospheric conditions conducive to ice formation are encountered during flight, presenting a critical area of focus for their research endeavors.

Ice accumulation on an aircraft during flight poses a significant risk, potentially impairing its performance and, in severe cases, leading to catastrophic consequences.

Fernández’s laboratory is dedicated to the development of algorithms and software tools aimed at comprehensively understanding these processes and leveraging this knowledge to enhance future aircraft designs, thereby mitigating potential negative outcomes.

The rebirth of commercial supersonic flight has kind of, sort of come to pass as Dawn Aerospace announces that its 16-ft (4.8-m) autonomous Mk-II Aurora rocket-powered aircraft broke the sound barrier with a speed of Mach 1.1 on November 12, 2024.

Ever since the Anglo-French Concorde retired in 2003, civil supersonic flight has been something of a lost art. In recent years, a number of startups have been working on various projects to create a new generation of supersonic transports that are quieter, greener, more efficient, and cost effective to operate.

Now, one supersonic aircraft has actually taken flight, albeit in the form of an uncrewed experimental craft with a wingspan of 13 ft (4 m) and a dry weight of 880 lb (200 kg). In the skies over New Zealand’s Glentanner Aerodrome near the base of Aoraki/Mount Cook, the Mk-II Aurora hit Mach 1.1 while climbing to an altitude of 82,500 ft (25,150 m).

Spanning 18 kilometers, the new Fehmarn Belt fixed link between Germany and Denmark will be the world’s longest and deepest underwater tunnel, combining road and rail.

Once completed, the tunnel promises to reduce travel time, strengthen ties between Scandinavia and Central Europe, form a greener traffic lane, and boost train transport. The ten billion euro price tag, therefore, promises to be worth it and has the stamp of approval from the European Commission’s Ten-T Programme.

The underwater fixed link tunnel will consist of two two-lane highways divided by a service passage and two separate railways.
