Recently, Casimir Space, a US startup, has announced the development of a chip that seems to produce a small amount of continuous, net Zero Point Energy (ZPE). This may be the first time that ZPE has been quantified. Although replication of this feat by other laboratories has not yet been reported, a useful exercise is to investigate the potential application of ZPE to interstellar travel. Here, ZPE is assumed to pump a large laser or laser array as the propulsion system of an interstellar generation ship. Apparently, such an approach as the primary propulsion system yields performance equivalent to that of fusion rockets or Sun-diving photon sails on voyages to the nearest extra-solar stars. But the ZPE laser, if it is feasible, can serve as a second acceleration stage and, if used continuously, can shorten voyage duration to more distant stars. This technology may allow the ultimate development of space habitats within the Oort Cloud, far from any source of radiant stellar energy.<\/p>\n<p class=\"p2\"><b>Keywords: <\/b>Zero-Point Energy (ZPE).
