The Direct Fusion Drive (DFD) is a nuclear fusion rocket engine based on the Princeton Field-Reversed Configuration (PFRC) machine about the size of a minivan. The DFD can generate propulsion by allowing energy to escape as a plasma plume. The concept of DFD allows deep space missions to fly directly to destination rather than having to use complex gravity assists from other planets. This seminar will discuss the physics & capabilities of DFD for space power & propulsion.
