M. Mansouryar’s preprint about a schematic design of a spacewarp machine in PDF format.
A design of a configuration for violation of the averaged null energy condition (ANEC) and consequently other classic energy conditions (CECs), is presented. The methods of producing effective exotic matter (EM) for a traversable wormhole (TW) are discussed. Also, the approaches of less necessity of TWs to EM are considered. The result is, TW and similar structures; i.e., warp drive (WD) and Krasnikov tube are not just theoretical subjects for teaching general relativity (GR) or objects only an advanced civilization would be able to manufacture anymore, but a quite reachable challenge for current technology. Besides, a new compound metric is introduced as a choice for testing in the lab.

As a matter of fact, the motivation caused me to start studying on spacewarps was the attempting to create a propulsion method, comparable to that of UFOs as the books I was reading, when I was a teenager. My model might be able to be considered as a nice explanation for propulsion of UFOs; For instance, I list 5 of them based on some reported cases as I remember:
