The first experimental observation of gaseous Bose-Einstein condensation (BEC) in 1995 created a huge wave of interest throughout the international Atomic Physics community. Unprecedented control of atoms became possible - macroscopic quantum objects could be created in which all atoms within the ensemble existed in the same quantum state. BECs are thus the equivalent of an atomic laser. The microscopic world of quantum mechanics entered a realm that could be viewed on an ordinary video camera. Pioneering work with BECs has already yielded a variety of intriguing phenomena.In this proposal we describe a technique whereby a giant toroidal BEC can be created. The benefits of such a BEC are many-fold. The toroidal geometry of the BEC will enable a detailed novel investigation of persistent currents and Josephson junctions in a dilute Bose gas. Possible developments in the area of super-sensitive gyroscopes exist. By generating large BECs, the ease with which applications such as nano-fabrication can be realised markedly increases. An obvious direction for future study would be the generation of the first continuous atom laser and the geometry of the proposed experiment lends itself to this development.
