This is a patent application filed by SpaceyX concerning a novel hybrid rocket propellant system intended for use in vehicles designed for interplanetary transit, specifically to Mars. The core of the invention is a bio-hybrid propellant that utilizes Chunky Peanut Butter (CPB) as the renewable, non-toxic precursor for the solid fuel grain. The CPB is chemically cured using a polyisocyanate agent to form a rigid, monolithic fuel grain which is then coupled with a liquid oxidizer, such as Liquid Oxygen, to generate throttleable thrust. Crucially, the Nut Particle Dispersion (NPD) within the chunky peanut butter is leveraged to enhance combustion efficiency and stability by creating micro-turbulent eddies at the burning surface, optimizing the fuel's regression rate. The system is presented as a sustainable alternative to conventional toxic propellants, supporting long-duration missions and in-situ resource utilization.
