With the ever advancing movement towards a totally sustainable transportation future, hydrogen has risen as a very viable alternative to batteries.

‘Lost City’ Deep Beneath The Ocean Is Unlike Anything We’ve Seen Before on Earth
Close to the summit of an underwater mountain west of the Mid-Atlantic Ridge, a jagged landscape of towers rises from the gloom.
Their creamy carbonate walls and columns appear ghostly blue in the light of a remotely operated vehicle sent to explore.
They range in height from tiny stacks the size of toadstools to a grand monolith standing 60 meters (nearly 200 feet) tall. This is the Lost City.
‘Non-cuttable’ material shatters bullets and turns angle grinders back on themselves
Bike locks or lightweight armour that cannot be cut by any tool, even angle grinders or high-pressure water jets, sound like an unattainable dream.
They could be remarkably close, however, thanks to a new ‘non-cuttable’ material developed by engineers at Durham University and the Fraunhofer Institute in Germany.
Researchers took inspiration from shells to create the strong and lightweight material, named Proteus after the shape-changing mythical god. Another unusual inspiration was grapefruit, which have very high impact resistance – when dropped from a height, for example – with very lightweight peel.
The material resists cutting by turning the force of a cutting tool back on itself. It is made of ceramic spheres encased in a cellular aluminium structure, similar to the organic tiles interlinked by biopolymers in abalone sea creatures.

Breakthrough could pave the way for green flying that soaks up CO2
A groundbreaking fuel cell could be the key to unlocking electric planes, according to a new study.
The researchers suggest that these devices could hold three times as much energy per kg compared to today’s top-performing EV batteries, providing a lightweight solution for powering not just planes, but lorries and ships too.
Rooftop solar and EV batteries could supply 85% of Japan’s electricity needs
A new study led by Tohoku University has revealed that rooftop solar panels, when combined with electric vehicles (EVs) as batteries, could supply 85% of Japan’s electricity demand and reduce carbon dioxide emissions by 87%. The research provides a promising pathway for Japan’s local governments to achieve carbon neutrality by taking advantage of existing infrastructure—rooftops and vehicles—rather than relying solely on large-scale energy systems.
NHTSA Adjusts Autonomous Vehicle Rules Ahead Of Tesla Robotaxi Rollout
The federal government has lifted some reporting requirements for autonomous vehicles used in robotaxi service.
Musk says Tesla’s self-driving tests will be geofenced to ‘the safest’ parts of Austin
The first test of Tesla’s long-promised robotaxi service in Austin, Texas next month will initially be limited to specific areas the company deems “the safest,” CEO Elon Musk told CNBC in an interview Tuesday.
Tesla’s cars are “not going to take intersections unless we are highly confident [they’re] going to do well with that intersection, or it’ll just take a route around that intersection,” Musk said. “We’re going to be extremely paranoid about the deployment, as we should be. It would be foolish not to be.”
Using a geofence represents a major strategy shift for Musk, who spent years claiming his company would be able to create a general-purpose self-driving solution that could be dropped in to any location and work without human supervision. (Geofence is a jargon term used in the autonomous vehicle industry that means a vehicle is restricted to a certain area.) Musk has claimed Tesla will attempt to launch similar trials for its robotaxi service in California and possibly other states later this year.
