One of the myriad issues with hydrogen as a clean energy source is infrastructure, as it’s very expensive to move around and store an extremely explosive gas. Toyota and its subsidiary Woven Planet believe they may have a solution with a new portable hydrogen cartridge prototype. The idea is that they can be filled up at a dedicated facility, transported where needed, then returned when you receive your next shipment.

The cartridges would be relatively small at 16 inches long, 7 inches in diameter and about 11 pounds in weight. Toyota calls them “portable, affordable, and convenient energy that makes it possible to bring hydrogen to where people live, work, and play without the use of pipes… [and] swappable for easy replacement and quick charging.”

They could be useful for “mobility [i.e. hydrogen cars], household applications, and many future possibilities we have yet to imagine,” Toyota said. It didn’t mention any specific uses, but it said that “one hydrogen cartridge is assumed to generate enough electricity to operate a typical household microwave for approximately 3–4 hours.”

DeLorean released images and information on its upcoming 2024 electric car.

DeLorean is unapologetically human. A New Energy mobility brand.

We have a clear vision of our future, knowing it does not represent today. The DMC-12 was never meant to be a static interpretation of the brand, the brand would constantly evolve. Our icons are reimagined. DMC is and always was in constant evolution. An Icon is validated over time but to constantly reimagine mobility allows new icons to come into existence.

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a stretchable and waterproof €˜fabric €™ that turns energy generated from body movements into electrical energy.

A crucial component in the fabric is a polymer that, when pressed or squeezed, converts mechanical stress into electrical energy. It is also made with stretchable spandex as a base layer and integrated with a rubber-like material to keep it strong, flexible, and waterproof.

Its called the Omega 1 and it is a rotary engine with no seals, barely any moving parts, and almost no losses in the combustion cycle. With a traditional internal combustion engine you lose stacks of energy through heat and friction, well with this new engine by Astron Aerospace. They aim to eliminate nearly all the losses associated with internal combustion.

Space, the final frontier. The starship Enterprise pursues its mission to explore the galaxy, when all communication channels are suddenly cut off by an impenetrable nebula. In many episodes of the iconic TV series, the valiant crew must “tech the tech” and “science the science” within just 45 minutes of airtime in order to facilitate their escape from this or a similar predicament before the end credits roll. Despite spending a significantly longer time in their laboratories, a team of scientists from the University of Rostock has succeeded in developing an entirely new approach for the design of artificial materials that can transmit light signals without any distortions by means of precisely tuned flows of energy. They have published their results in Science Advances.

“When light spreads in an inhomogeneous medium, it undergoes scattering. This effect quickly transforms a compact, directed beam into a diffuse glow, and is familiar to all of us from summer clouds and autumn fog alike,” Professor Alexander Szameit of the Institute for Physics at the University of Rostock describes the starting point of his team’s considerations. Notably, it is the microscopic density distribution of a material that dictates the specifics of scattering. Szameit continues, “The fundamental idea of induced transparency is to take advantage of a much lesser-known optical property to clear a path for the beam, so to speak.”

This second property, known in the field of photonics under the arcane title of non-Hermiticity, describes the flow of energy, or, more precisely, the amplification and attenuation of light. Intuitively, the associated effects may seem undesirable—particularly the fading of a light beam due to absorption would seem highly counterproductive to the task of improving signal transmission. Nevertheless, non-Hermitian effects have become a key aspect of modern optics, and an entire field of research strives to harness the sophisticated interplay of losses and amplification for advanced functionalities.

Power-hungry, fossil-fuel dependent Japan has successfully tested a system that could provide a constant, steady form of renewable energy, regardless of the wind or the sun.

For more than a decade, Japanese heavy machinery maker IHI Corp. has been developing a subsea turbine that harnesses the energy in deep ocean currents and converts it into a steady and reliable source of electricity. The giant machine resembles an airplane, with two counter-rotating turbine fans in place of jets, and a central ‘fuselage’ housing a buoyancy adjustment system. Called Kairyu, the 330-ton prototype is designed to be anchored to the sea floor at a depth of 30–50 meters (100−160 feet).

Tested in one of the world’s strongest ocean currents, a prototype generator could herald the start of a new stream of renewable energy.
