Advanced Propulsion Systems

The probable scenario in which an autonomous drone can travel from London to Victoria in the Seychelles in under an hour, powered solely by renewable energy, is within grasp. No emissions, no refuelling, no compromise. We are exploring the systems that will redefine global mobility, fusing speed, autonomy and sustainability to create entirely new modes of intercontinental transport.


Urban centres and remote regions alike could be linked by hyper-speed aerial vehicles capable of transporting passengers or cargo in minutes rather than hours. These systems would operate far above current aviation altitudes or in near-orbital corridors, drawing power from solar arrays, green hydrogen fuel cells or magnetic propulsion. This is not merely an upgrade of existing transport, it is a conceptual leap beyond the constraints of fuel-based aviation and terrestrial logistics.


Research in solar-electric propulsion, such as demonstrated by NASA’s X-57 Maxwell project (Borer, 2024), has already laid the groundwork for all-electric flight. Hydrogen-based flight systems, like those explored in the HyFlyer programme (ZeroAvia, n.d), show early promise in achieving clean propulsion at regional scales. Meanwhile, advances in magnetic levitation and superconducting systems (Samlib.ru, 2015), as proposed in studies on vacuum tube transport (Zhong et al., 2021), point to entirely new propulsion paradigms that could be adapted to high-altitude, long-range drones.

We are investigating how these emerging propulsion methods can be scaled, miniaturised and integrated into systems that defy conventional limits. From aerodynamics to energy storage, our research targets the physical and computational bottlenecks that must be overcome to realise emission-free, ultra-fast aerial mobility.


Our focus is on the development of high-speed transport systems that operate with zero carbon emissions. This includes drone platforms, autonomous navigation, power-to-weight optimisation, and alternative propulsion. We seek to build a foundation for the next generation of aviation, clean, fast and globally connected.


We are seeking partners who are ready to explore the outer bounds of transport innovation. The path forward is uncertain, but the goal is clear: a world where speed and sustainability coexist. Join us in building a future of flight that leaves no footprint.
