A rotary propulsion engine system designed to propel a craft. Such a rotary propulsion engine system comprises a power supply, a counterrotating disc assembly including two axially and rotatably connected discs, a drive mechanism to rotate the two counterrotating discs, an axle assembly, at least two reaction masses or armatures, at least two reaction mass driver assemblies, and at least two travel pathways for the reaction masses. Reaction masses are fired into a rotational environment wherein the kinetic energy of the reaction masses is recycled, thereby reducing or eliminating the need for chemical propellant-based propulsion systems, and transporting heavy, finite, and expensive fuels for combustion.

An apparatus for generating electricity from falling material includes a capture wheel arranged to receive a falling material and be rotated thereby. The capture wheel may be mounted on a transportable housing having a generator therein. The housing may be a shipping container and the apparatus may be arranged to fit entirely within the shipping container for transportation. The capture wheel may include a hub comprising a central core encapsulated in a layer of resilient material; a wheel framework extending from the hub, wherein the wheel framework is connected to the resilient layer; and a plurality of bucket sections mounted on the wheel framework and arranged to receive the falling material. The hub may be a tri-layer hub including a central core, a layer of resilient material, and an outer support ring surrounding the layer of resilient material. A method of generating electricity using such an apparatus is also disclosed.

Disclosed are systems for converting rotational momentum into linear propulsion. A propulsion system includes one or more thrust units with masses controllably driven by actuators to generate inertia that thrusts a vehicle with the propulsion system in a desired direction. The propulsion system can be configured to have multiple units, each configured to generate thrust in a desired direction and counteract or neutralize thrust in other directions. The propulsion system can generate thrust via two operational cycles and/or through continuous operation. The propulsion system may comprise two mirroring units, each configured to operate in mirrored synchrony to generate a net thrust in a desired direction and counteract or neutralize thrust in other or undesired directions.
