The aircraft – which is currently under construction – will use hydrogen fuel cells to power electric motors, with the only emission being “water vapour at manageable temperatures”.

Zeroavia said that “The deal sets a solid timeline for the launch of the first zero emission commercial passenger flights between the UK and the Netherlands, and potentially the first international commercial operation in the world”.

The partnership will see Zeroavia and Royal Schiphol Group collaborating on “testing and demonstrating hydrogen supply chain refuelling operations and integration with airport operations”, as well as “ensuring the pathway for commercially adopting hydrogen-electric aviation, including establishing the right regulatory framework and understanding industry and public appetite for zero emissions flight powered by hydrogen”.

In December 2020 British Airways announced a partnership with Zeroavia to explore “the transformational possibilities of moving from fossil fuels to zero-emission hydrogen to power the airline’s future fleet”.

Oliver Schwab, Project Manager Porsche Mobil 1 Supercup said :

“The Supercup is the first international racing series to use renewable fuels. Given that our races are held as part of the FIA Formula 1 World Championship, we’re very much in the eye of the media, the public and other manufacturers involved in motor racing. As a pioneer in the use of synthetic fuel in Porsche race cars, the Porsche Mobil 1 Supercup takes on an important communication function for the significance of eFuels at Porsche.”

And what about productions cars ?

Following their world premieres in Los Angeles, the Porsche 718 Cayman GT4 RS and its Clubsport variant have caused a stir at the GP Ice Race in Zell am See. Beyond the spectacular drives on ice and snow, their fuel also garnered some attention: they were powered by renewable petrol.

The GT4 RS models were powered by synthetic fuels, which can make an important contribution to lowering carbon emissions in the transport sector. In this case, the fuel was a renewable petrol based on an advanced biofuel made of food waste products. The fuel had previously demonstrated its suitability for use in high-performance Porsche engines in the Porsche Mobil 1 Supercup, where it was used in all the teams’ 911 GT3 Cup cars for every race of the 2021 season.

The halo is a driver crash-protection system used in open-wheel racing series, which consists of a curved bar placed above the driver's head to protect it. the halo is so strong that it is capable of withstanding a load of 125 kiloNewtons of vertical force, or a London tourist bus (12 tons).

The halo is a recent innovation from 2018 wich saved around 10 driver's life in differents motorsport categories. The most "famous" crash in wich the halo saved a life is on the next document.

The physicist who works for the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) designed the rocket which will use magnetic fields to shoot plasma particles - electrically charged gas - into the vacuum of space.

According to Newton's second and third laws of motion, the conservation of momentum would mean the rocket was propelled forwards - and at speeds 10 times faster than comparable devices.

"During its operation, this tokamak produces magnetic bubbles called plasmoids that move at around 20 kilometres per second, which seemed to me a lot like thrust," Dr Ebrahimi added.

Data is collected from cars during races and training sessions, with the average car equipped with more than 300 sensors and transmitting around 3 GB of telemetry data per race.

Over the past year, CFD has been used to evolve F1 in line with fan expectations. Using fan feedback, F1 realized that spectators wanted to see closer wheel-to-wheel racing. However, the aerodynamic “wake models” widely used until recently were not conducive to this type of racing, because they created strong turbulence in the wake of vehicles.

Thus, a collaborative project between F1, the FIA ​​and AWS was born, in order to determine the modifications to be made to the aerodynamics of the vehicles to offer closer races during the 2022-2023 season.

For example, Ferrari’s powerhouse, the SF90 uses a twin-part rear wing as an application of the drag reduction system. On the other hand, cars like the Ford Mustang, BMW M5, and even older Chevy Cruze sedans leverage similar F1 technology. 

In these cars, active grille shutters engage at specific speeds to minimise drag and enhance fuel efficiency at higher velocities, while the shutters open again to improve engine cooling when the speed decreases.

That ridge-lined inner surface of the wheel is the hub—just a very large, hollow hub. It’s anchored to the bike’s frame, while the rest of the wheel rotates around it. And the ridges are actually radiator fins. Their job is to dissipate heat from the engine. Because the wheel is the engine.

How it is done ?

The heart of it is two concentric bands of magnets with a bearing in between, so one band can rotate around the other. The inner band is fixed to the hub and consists of electromagnets. The outer band is ordinary magnets. Pulses of power to the electromagnets create push and pull between the two bands and make the wheel spin

Advantages ?

Having the engine in the wheel means two key things. First, the entire body of the bike can be given over to a battery pack. This gives the thing a range of up to 375 km (233 miles) for the top-end TS Ultra model.

Second, there’s no transmission: no shafts, gears, belt, or chain transferring rotational movement from engine to wheel. With fewer moving parts, Verge says, the bike is both more reliable and more powerful, because less energy is lost to friction.
