The first form of Æther Propulsion used in the late 1800s. Early æthernauts used this system of æther propulsion to venture to Mars and Venus.
The drive works on the principle of charging a mechanical screw type propeller with phenolic energy allowing the propeller to push against the ætheric medium.
The æther propellor was eventually replaced with wedge drives which were faster and more efficient. Even today you can still find ships using this slow yet reliable method of æther propulsion.
