Kinetic Energy is viewed as an in-situ resource. An Impulse Engine (formerly named a Recycler, or a CataMitt Recycler) is a large device that extracts kinetic energy from an arriving spacecraft, converts it into electricity via regenerative braking, and immediately applies that electricity to launch a partner spacecraft. This enables space hardware to shift from being primarily expendable to being primarily reusable in nature. While it has constraints, it also has a significant potential to reduce the cost of round trip space travel between select destinations, such as a Molniya orbit, geosynchronous orbit, and the Moon.
