A carbon fiber having a terminal glucose oxidizing microanode and an O2 reducing microcathode is propelled at the water-O2 interface. The electron current in the fiber is accompanied by a flux of hydrated protons that is so fast at the solution-air interface, where the viscous drag is small, that the fiber's velocity is 1 cm s-1.

This record presents a propulsion framework (“Impossible Drive”) based on a one-dimensional cavity boundary reduction. The model enforces conservation through photon closure inside the cavity and graviton exhaust as the external reaction partner. It is part of the Big Mama series of white papers, which develop the theoretical and engineering principles

To produce supersonic laser propulsion, a new technique based on the interaction of a laser-ablated jet with supersonic gas flow in a nozzle is proposed. It is shown that such parameters of the jet, such as gas-plasma pressure and temperature in the ablation region as well as the mass consumption rate of the ablated solid propellant, are characteristic

Propulsion Systems PNN (Non-Newtonian Propulsion)
Journal of Physics & Optics Sciences, 2023As the facts incontrovertibly demonstrate, rocket astronautics has been unable to place permanent outposts on the Moon since the time of Apollo 11 or more than half a century ago. I don't know if you realize that today with Project Artemis NASA is trying to redo what it did over 50 years ago!

Few aeronautical engineers would disagree that the development of new propulsive systems has been the main influence responsible for the achievement of supersonic flight. This is not the same thing as claiming that sustained flight at these speeds, over fairly long ranges and with reasonable economy, would ever be possible without correspondingly large
