In vacuum (outer space), it can be assumed that complete convergence of artificial light energy can be achieved with high-performance concave spherical mirrors. These mirrors are to provide, for example, a constant heat of several million degrees by reflecting and bundling the flash of an atomic explosion. A frozen globule of heavy water (deuterium) approaches two facing mirrors at the focus. The energy released by the nuclear fusion is also reflected by mirrors, and generates the thrust. Field of application: stellar travel.
