Abstract: Oar, ancient propulsive mean is known many hundreds years ago and is not exchanged until now. Here is offered a new paddle device—a paddle aqua-glider able to exchange oars partially and it is able to expand applicability of manual paddle means much far. The paddle aqua-glider combines ability to glide forward with ability to rise up and to function as a paddle when backward force (such a cord tension) applied to it.

Abstract: The wave powered (WP) propulsion systems developed in great amount for boats are not in use because of small effectiveness caused by rocking process reducing propellor stroke relatively water. Submarines and special quasi-dipped watercrafts deprived of this disadvantage. Their bodies keeps stable the propellors mounted on conning towers or special props owing to the body's great mass. This factor multiplies the WP propellor effectiveness meeting Navy and Merchant fleet requirements.

Abstract: The new gyroscopic device (gyro-dipole) has two gyroscopes with equal angular momentum (gyro-twins) set in a common case with precession axis's disposed parallel and engaged via gears allowing gyro-twins to precess synchronical but contrary.

Abstract: A helicopter can't moor to a wall or land on slope surface. Maneuvering a helicopter changes angle positions and loses targets. Its screw closes operating space above. Here is given the design of a flying and soaring device (rotopter) free from these problems. It uses side circulating wings whose quasi-horizontal paths of circulation provide necessary thrust for hovering, lifting and flying.

Abstract: Method of cyclic anchoring itinerant (CAI) propulsion uses a phenomenon of anchored float horizontal motion as wave rises.

Abstract: The invention accesses an inexhaustible energy source of the ocean to produce ship propulsion and to generate electrical energy.

Abstract: To access the inexhaustible energy source like seas and oceans we need to learn how to convert its wave motion to the customized power for our ships, for our existing littoral settlements and our future ocean settlements. Here is an attempt to develop method of the conversion the wave energy to power with floating means based on a gyroscope strong capability to resist against the outer force moment trying to tilt it to any side. The gyroscope is used as the fulcrum torque dynamic supporting instead traditional static base used in the issued devices. Alternate force moment created by the waves and transmitted to the gyroscope (via the floating body and the wave energy converter) inducts alternative gyro precession so as the gyroscope axis hesitates about mean position. This is important because it allows the gyroscope to keep dynamic fulcrum torque in unlimited time.

Abstract: For any directed sea waves the rocking propelled ship can reach high speeds if it utilizes an sea waves energy by means of1. A rocking propulsor, which is a couple of hydrofoils kept elastic cross by pivots on the extreme points of streamline narrow keel-rocker, extended far out off long sizes of the ship and thus wags hydrofoils vertically with a speed and an amplitude being sufficient for its proper work;2. A "pendulum design" of a rocking propelled ship, described by a light wide body with weight, concentrated in a middle lowest ship's part and having a vertical keel with a heavy bob. This design provides the highest efficiency of an energy transmission from waves to ship rocking.In case of need to increase ship's speed some more its rocker should be rigged by an on-board oscillator, which is a central heavy flywheel, which is alternately twisted up to speed by a serve motor in both directions on cross axle in time (resonance) of ship rocking.
