Orbital Sea is driven by a passion for physics and hands-on experimentation. Operating primarily in aerospace and military sectors, we conduct rigorous research, including private and confidential projects, to develop advanced technologies. At the same time, we are committed to bridging the gap between theory and experiment by openly sharing classic and novel physics experiments with the public.

By combining cutting-edge, sensitive research with transparent educational content, Orbital Sea aims to inspire and educate curious minds while pushing the boundaries of practical science and technology.

Orbital Conveyor Belt (OCB)

OCB is a concept for moving mass through space without using propellant. It works by coordinating satellites that pass payloads between each other through carefully timed momentum exchanges. Using electric motors, solar sails, and precise orbital mechanics, this network of satellites acts like a conveyor belt in orbit, moving cargo precisely along natural orbital paths. The system grows stronger as more satellites join, forming a web of paths defined by the natural motion of orbiting bodies. By working with the physics of curved paths and Newton’s third law, the Orbital Conveyor Belt offers a new way to move cargo in space without fuel.

Gyroscopic Gun (GG)

GG explores a new class of projectile launchers based on the sling effect: converting angular momentum into linear momentum through controlled rotational acceleration. Inspired by ancient slings and modern rotational sports like the hammer throw, the GG uses continuous torque applied over multiple rotations to build up projectile speed far beyond what linear acceleration methods can achieve in the same space. Using electric motors for precise control, this system offers scalable, silent, and highly efficient propulsion without combustion. The gyroscopic stabilization inherent in the rotating mechanism adds natural aiming stability, making it suitable for advanced aerospace and defense applications. By harnessing these physics principles, the Gyroscopic Gun promises a fresh approach to propulsion and projectile acceleration that combines precision, energy efficiency, and sustainability.

Sling Propulsion Transit Network (SPTN)

SPTN is a new approach to surface-to-surface transport using a network of mechanical sling launchers paired with autonomous vehicles. Instead of relying on onboard propellant, these vehicles gain and transfer kinetic energy by being launched and caught at each node in the network, creating an energy efficient, reusable system. The sling-based launchers impart velocity through controlled rotational acceleration, allowing payloads to travel predictable paths across planetary surfaces or between stations with minimal mechanical stress. Designed for environments ranging from Earth’s remote regions to airless bodies like the Moon or Mars, the system requires little continuous infrastructure and scales easily as new nodes are added. By recycling momentum and using electric power, the Sling Propulsion Transit Network offers a sustainable and modular transport solution suited for future exploration and logistics.

Vortex Sigil (VS)

VS develops advanced silent propulsion systems designed specifically for submersible crafts.

Wilter Franceschi is an independent researcher dedicated to exploring fundamental principles of physics through the lens of Anglemetric Theory, a framework emphasizing the central role of rotational dynamics and angular relationships in nature. From his teenage years, Wilter has pursued astronomy and physics through self-study, striving to connect mathematics with the history and foundations of physical laws. He values experimentation above theory, inspired by Richard Feynman’s principle: “It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.” Wilter’s professional background includes service as a Military Technology Technician in the Brazilian Navy, working extensively with advanced systems such as radars, gyroscopes, AIS, and GPS. In parallel, he has developed software across the full stack—from low-level systems programming to high-level web applications and e-commerce platforms. His multidisciplinary experience informs his innovative approach to propulsion and motion, blending practical engineering with theoretical insights.
