The scaled model at nearly 1/100000th of expected size to be built in space, was fashioned from an antique Star Trek model kit, that thankfully with today's technology is easy enough to replicate. We're not talking transporters here, just good cash to a high end reproduction facility which specializes in anything made of plastics.
The drive is best described as a Venturi, a common method of air induction in race car bottoms and carburators. The basic principal is that a large mouth will intake the desired fuel (air/water etc.) and forcibly push the fuel through a much smaller conduit (tube) to create propulsion. For something of this magnitude the intake end of the venturi on the real craft was about the size of a large house, whereas the exhaust end would be as small as possible for absolute maximum speed. In theory at least, the idea had some merit. With luck a scale model with a hole the size of a small coin for the intake end, and a pinhole for the exhaust may be able to convince the brass of the outfit to invest further into the project.
Enterprise (the model) was carefully deposited in the chamber, tied to a fishing line. The AA cell battery charger operated by a vidscreen remote would initiate the rotation of the drive. Yes, in order to fully extrapolate more speed, the drive would also be rotary, not like the early years of Mazda, with a spinning piston of sorts, but the actual chamber would spin. The objective of the battery charge was to begin the rotation with a belt driven motor similar to of all things, a vacuum cleaner. Once the test chamber was sufficiently transformed into a near vacuum by using one to remove most of the air contents, the test could begin. The theory was that once in motion, any matter no matter how infinitessimal would be sent through the venturi and continue its propulsion enough to disengage the battery drive, and quite effectively become a zero emmisions spacecraft.
Now we wait to see if it works.
