Alpha Impulsion: This French Startup Wants to Burn Its Own Rocket as Fuel [e6blDhxIuj6]
Alpha Impulsion is developing one of the most unusual propulsion concepts in the space industry, an autophage (or “self-eating”) rocket engine that consumes its own structure as fuel. In this video, I break down how the technology works, examine their Grenat launcher and Opal in-space thruster, and analyse their strategy of starting with a space tug before building a full orbital rocket. We also look at the challenges of scaling autophage propulsion and whether this approach could succeed in an extremely competitive launch market. ------- Love learning about space startups?
