GE Aerospace tests new hybrid electric engine for future aircraft
GE Aerospace announced a significant milestone in hybrid-electric aviation with the successful ground test of a modified Passport high-bypass turbofan engine capable of extracting, transferring, and reinserting electrical power during operation. Conducted in 2025 at GE’s Peebles Test Operation in Ohio under NASA’s Turbofan Engine Power Extraction Demonstration project, this integrated test demonstrated a full hybrid electric engine system working together in real conditions. Unlike traditional hybrid designs, the engine supplements thrust electrically without relying on onboard batteries, reducing weight and complexity while maintaining flexibility. This breakthrough aims to improve efficiency and durability for next-generation single-aisle commercial aircraft in the U.S. The collaboration with NASA marked the first time electric motors, power electronics, and control systems were integrated inside a working turbofan engine, surpassing technical benchmarks designed to ensure meaningful fuel savings and meet future power demands. Although the hybrid engine still burns jet fuel, electric assistance enhances key operations, requiring new design and safety validation approaches distinct from hybrid car technology.

Ukraine has deployed a world-first hybrid hydrogen-powered drone, a modified version of Skyeton’s Raybird, in an active combat zone for reconnaissance missions. Unlike the standard Raybird, which uses an internal combustion engine (ICE) and can fly for over 28 hours, the hydrogen-electric variant offers a flight endurance of 12 hours (with plans to increase to 20 hours) and features a significantly lower heat signature. This reduced thermal footprint, due to the electric motor generating less heat than an ICE, makes the drone especially suited for stealthy surveillance in hostile environments. The redesigned Raybird incorporates hydrogen cartridges to power electric motors, providing quieter operation, higher operational altitude, and environmental benefits. The drone weighs 51 pounds, has a 15-foot wingspan, and can carry a payload of about 22 pounds, including radar and surveillance sensors. Skyeton spent two years in research and development to address challenges such as climate resilience and hydrogen logistics, resulting in a reliable platform that balances long-duration flight

The article discusses a recent development in the electric vehicle (EV) industry, highlighting Ford's surprising strategic shift that appears to scale back its EV ambitions, which the author views as a setback for EV progress. In contrast, General Motors (GM) released a detailed explainer on how EV drive units work, which the author interprets as a subtle form of trolling aimed at Ford. GM’s article emphasizes their deep expertise in EV technology, positioning electric vehicles as their guiding principle ("North Star") and showcasing their in-house design capabilities for key components like the motor, inverter, and gearset. GM’s explainer compares an EV drive unit to an orchestra, where the inverter acts as the conductor converting battery-stored direct current (DC) into alternating current (AC) to power the motor, which is likened to the musicians producing motion. The motor uses permanent magnets to generate torque through magnetic attraction and repulsion, driving the vehicle’s wheels. The article implies that GM is confident in its EV technology

The hyperloop, a concept for ultra-fast, near-silent travel through low-pressure tubes, traces its origins back to 1799 with George Medhurst's early pneumatic transport ideas. Revived in 2013 by Elon Musk, the hyperloop aims to offer speeds up to 760 mph by using magnetic levitation or air bearings to lift passenger pods inside sealed, low-pressure tubes, drastically reducing air resistance. This technology promises rapid journeys—such as San Francisco to Los Angeles in 35 minutes—while being more energy-efficient and environmentally friendly than traditional transport and air travel, with fewer delays and no airport congestion. Despite early enthusiasm and the formation of startups like Hardt Hyperloop, progress has slowed due to significant engineering challenges. These include integrating vacuum systems, magnetic levitation, emergency protocols, and scalable lane-switching for networkability. According to Hardt Hyperloop co-founder Tim Houter, resolving these issues is critical for moving beyond test tracks to full-scale networks. Public acceptance also remains
