Our first fully-integrated vehicle.
This non-flying prototype acted as a ‘dynamic iron bird’ to validate all major aircraft subsystems in a real-world environment.
The development and testing of Mk 0 epitomize our core tenets of hardware richness and rapid real-world testing.

We’re on a journey to advance and democratize artificial intelligence through open source and open science.
China has taken significant steps toward developing high-speed transportation after testing a maglev train in a vacuum tube.
China’s groundbreaking maglev train, capable of reaching speeds up to 1,000 km/h, and its potential impact on global transportation and the environment.
In a bold move towards sustainability in the automotive industry, Alpine has introduced its new V6 hydrogen engine. The engine is a groundbreaking development that merges high-performance engineering with eco-friendly technology. This innovative engine represents a significant leap for the French automotive brand, showcasing its commitment to advancing hydrogen as a viable fuel alternative in the world of motorsport and beyond.
While Japanese automobile company Toyota continues to be leading the hydrogen revolution, other automobile companies are following closely behind. While some have placed all their bets on electric vehicles being the future of sustainable engines, others are looking at ways to continue producing the internal combustion engine. The answer may be found in hydrogen technology whereby traditional internal combustion engines can be adapted to support the alternative fuel source.
Alpine previously introduced a hydrogen powered car in 2022. Now, the newer model is twice as powerful as the last. The car features a 3.5-litre, twin-turbo V6 engine. It produces a power output of 740bhp, and can reach up to 9,000rpm with 770 Nm of torque. The two hydrogen engines are located in the sidepods and behind the cockpit. The model has been in the works for two years and is a testament to Alpine’s continued dedication towards sustainability.
Tesla added more market value Thursday than the combined valuations of top U.S. competitors Ford and General Motors.
Researchers at McGill University have made a significant advance in the development of all-solid-state lithium batteries, which are being pursued as the next step in electric vehicle (EV) battery technology.
By addressing a long-standing issue with battery performance, this innovation could pave the way for safer, longer-lasting EVs. The findings are published in the journal Cell Reports Physical Science.
The challenge lies in the resistance that occurs where the ceramic electrolyte meets the electrodes. This makes the battery less efficient and reduces how much energy it can deliver. The research team has discovered that creating a porous ceramic membrane, instead of the traditional dense plate, and filling it with a small amount of polymer can resolve this issue.
The Airwolf hoverbike is designed to soar with speed, efficiency, and agility. Using individually tilting ducted fan propulsion technology.
But when something out of the ordinary happens, the situation can quickly get scary, because most updates are only delivered by audio announcements. A Deaf traveller may miss their train because it was moved to a different platform, or watch as their station whizzes by because the train isn’t stopping there today. They may also remain on a train carriage in an emergency after everyone else has evacuated, and have to be rescued by station staff.
Every single one of these examples has been drawn from the real life experiences of Deaf people in Sydney. But my colleagues and I are working with Sydney Trains and members of the Australian Deaf community to develop an advanced, artificial intelligence (AI)-powered signing avatar which can automatically translate audio announcements into Auslan.
Just as we mimicked birds and fish to model cars and planes, we may gain inspiration for deep dive vehicles.

The bottom of the ocean is cold, dark, and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At the deepest point, the pressure of 36,200 feet of seawater is greater than the weight of an elephant on every square inch of your body. Yet Earth’s deepest places are home to life uniquely suited to these challenging conditions. Scientists have studied how the bodies of some large animals, such as anglerfish and blobfish, have adapted to withstand the pressure. But far less is known about how cells and molecules stand up to the squeezing, crushing weight of thousands of feet of seawater.
