The VEHICLE WITH TRAVELING WAVE THRUST MODULE APPARATUSES, METHODS AND SYSTEMS include force or forces applied to an arc-like flexible sheet-like material to create a deformed crenated strip fin with strained-deformations. The strained-deformations take on a sinusoid-like form that express the internal energy state of the flexible sheet-like material after it has been configured into a crenated strip fin. After being incorporated into a mechanism with couplings that prevent the crenated strip fin from returning to its un-strained state, the strained-deformations persist. Actuators may be used to sequentially rotate vertebrae attached to the fins causing the travel of sinusoid-like deformations along the fins. The fin, fin actuator or actuators, power source and central controller may be incorporated into a thrust module. Two thrust modules couple to each other via roll actuators and flexible coupling members may form a vehicle with exceptional maneuverability.

Systems and methods for generating electricity from a fluid turbine are provided. In one aspect, the system employs a Tesla turbine to rotate a drive shaft, the drive shaft providing torque to operate an electrical generator. The incoming fluid flow that operates the Tesla turbine enters a hollow portion of the drive shaft and exists the system as an exhaust flow. The system may operate from standard water supplies provided to a residence or business, thereby reclaiming excess water pressure energy.

A boundary layer turbomachine can include a housing (10) defining an interior space and having an inlet opening and an outlet opening to facilitate movement of a fluid through the housing (10). The boundary layer turbomachine can also include a rotor assembly (20) disposed in the rotor chamber and configured to rotate about an axis of rotation (1). The rotor assembly (20) can have a plurality of disks (21) spaced apart along the axis of rotation (1) to provide gaps (54) between the disks (21). The plurality of disks (21) can also define an interior opening (26) along the axis of rotation (1). The rotor assembly (20) can have a disk carrier (46) disposed at least partially in the interior opening (26) in support of the plurality of disks (21). The disk carrier (46) can have a fluid passageway (47) exposed to two or more of the gaps (54) between the disks (21). The fluid can pass through gaps (54) between the disks (21) and the interior opening (26) as the fluid moves through the housing (10).
