Came across this. Any aviation fans? MIT does it again but this time with propellers.
Hope you all enjoy it.

Amid the fierce competition throughout the globe to develop hydrogen mobility technologies to achieve carbon neutrality, a new technology for a 2-liter class hydrogen-fueled engine (a passenger car hydrogen engine) capable of running entirely on hydrogen has been developed for the first time in Korea.
The joint research team led by Principal Researcher Young Choi of the Department of Mobility Power Research of the Korea Institute of Machinery and Materials (KIMM), and Researcher Hong-gil Baek of the Zero-Carbon Engine Research Lab of Hyundai-Kia Motor Company (HMC) developed the “direct injection hydrogen engine” that runs entirely on hydrogen fuels, and demonstrated its world-class excellence through performance evaluation.
The joint research team of KIMM and HMC injected hydrogen directly into the combustion chamber of the engine of HMC’s existing hybrid vehicle, with a pressure of more than 30 bar. By using a turbo charger that improves the performance of the engine, the research team was able to maintain high thermal efficiency in all domains from the ignition of the engine to the upper limit of the engine load, allowing the engine to be stably operated throughout the entire engine operating conditions.
New technology allows hydrogen to be directly injected into the cylinders like an internal combustion engine.
As the world scrambles to transition to green fuels to achieve carbon neutrality, promoting power sources that use hydrogen as a clean fuel is one strategy to further the move. Now, researchers in South Korea have developed a new technology for a passenger car hydrogen engine that promises to make it more viable for mass production.
The powertrain developed by researchers at the Korea Institute of Machinery and Materials (KIMM) and the Zero-Carbon Engine Research Lab of Hyundai-Kia Motor Company (HMC) is a 2-liter direct injection hydrogen engine that runs entirely on hydrogen fuel.
Tesla is still fighting for its North American Charging Standard chargers to become dominant over the Combined Charging System chargers, which are used by most other electric vehicles in the United States. Now, the company is releasing a new product that could help its cause.
The product, called the Tesla Universal Wall Connector, is a new version of the EV company’s home charging Wall Connectors. But unlike the old Tesla Wall Connectors, which are only compatible with NACS (and therefore can only charge Teslas), the Tesla Universal Wall Connector will also be compatible with CCS plugs.
As Electrek pointed out, this is similar to what Tesla has done with its Magic Dock adapters installed at some Supercharger stations, which can charge both Teslas and non-Teslas alike.
The long-promised more affordable Tesla electric car might debut alongside an automated robotaxi.
Tesla is reportedly preparing to build a $25,000 electric car built on the company’s next-generation engineering platform. Axios.
The $25,000 car reportedly has a futuristic design like the long-delayed Cybertruck — the angular pickup truck that Tesla first revealed in 2019. The Cybertruck will supposedly begin production this year, with production-at-scale beginning in 2024.

Robotaxi company Cruise is “just days away” from getting regulatory approval that would pave the way for mass production of its purpose-built driverless vehicle, CEO Kyle Vogt said on Thursday in comments reported by the Detroit Free Press.
General Motors-backed Cruise unveiled the vehicle — called Origin — in early 2020, presenting the kind of driverless car that we all dreamed of when R&D in the sector kicked off years ago; a vehicle without a steering wheel and without pedals. A vehicle with passenger seats only.
Germany-based aviation company H2FLY has successfully completed the world’s first piloted flight of an electric aircraft powered by liquid hydrogen.
The flight lays the foundation for long-range, emissions-free flight with liquid hydrogen.
Removing membranes could shave off as much as 30 percent of battery costs since they are the most expensive components.
Researchers at the University of Cincinnati in the US have developed a new design that could make lithium-ion batteries much cheaper to produce. This can have a profound impact on the large-scale energy storage systems needed to store renewable energy, a press release said.
Lithium-ion batteries, extensively used for power electronic devices, have also found their way into electric vehicles (EVs) thanks to their superior energy density over conventional batteries. These can also be deployed to store renewable energy when production is high, but the demand is low.
A new facility will be able to produce battery capacity to power 130,000 homes on a daily basis using renewable energy.
Zinc halide batteries touted as a low-cost alternative to battery energy storage system (BESS) have received a significant boost in the US after the Department of Energy (DOE) offered a $400 million loan to help scale production and reduce manufacturing costs, a press release said. The offer will cover setting up of four production lines at battery maker Eos’ facility in Turtle Creek, Pennsylvania.
Lithium-ion batteries are a crucial component of our attempts to switch to a greener economy powered by renewable energy. Although the technology is ubiquitous these days and powers everyday devices like smartphones and even electric vehicles (EVs), it is still very expensive.
