The invention relations to hydroelectric power industry and can be used for capturing the energy stored within atmospheric moisture at any locations worldwide. The device comprises a tail race (1), a head race (2), a water conduit (3), a turbogenerator (4), meshed, woven or filmed surfaces (5), an airship (6), and fastening cables (7). The airship (6) raises the surfaces (5) to the altitude above the dew point corresponding to the given atmospheric conditions (usually, 2-3 km). There, are supercooled atmospheric moisture starts to condense (accumulate) actively on the surfaces (5). A drainage system provided on the surfaces (5) takes this water to a small reservoir (head race 2), from which the water, under a head caused by the entire altitude level difference, passes along the water conduit (3) into the tail race (1) on the ground, thereby producing electrical power in the turbogenerator (4).

||14386493||AALTO UNIVERSITY FOUNDATION||Olof Calonius|
An adaptive hydraulic pressure generator is provided for systems in which the mechanical force producing energy varies significantly, especially for wave energy systems. The pressure generator includes at least two fluid chambers with a piston surface/displacement surface arranged to reciprocate with the fluid chamber, whereby the piston surface/displacement surface acts on the fluid in the chamber by means of the said mutual reciprocating movement. The pressure generator is equipped with a control system which is arranged to connect the chambers to each other and/or to different pressure ducts in such a way that the effective area of the piston/displacement surfaces changes in accordance with the changes in the driving force exerted on the piston/displacement surfaces and/or the body forming the fluid chamber in such a way that the pressure produced by the pressure generator in the fluid supplied to the application exceeds the threshold pressure.

Perpetual movement device for a circumference with an endless chain energy generator. The invention relates to the different alternative of endless chains together with its gear, housing, toothing and in the form of a hook retractable into the circumference and/or a crown. It is made up of a roller link, bead, bucket, magnet chain together with its toothing or housing. Comprising a "male" tooth in the form of a retractable hook, sliding in a "female" sheath, both provided with a pin gripping a spring. Such that at each roller, a bead bears on the rounded hook at each tooth; thus, it retracts into its sheath. This tooth is equipped with a sealing pad, an adjustable screw that positions the tooth by gravitational and centrifugal force. This chain can be meshed at the outside of the circumference by 2 pinions, i.e. an engaging pinion at 12:00 and disengaging pinion at 6:00, fastened on a moving plate; the 2 pinions of same are oriented across from one another, forming a rotational angle ≈ 45°. One pinion guides the chain, while the other pinion grips it abutting and thus orients the chain. Magnet or "flat" magnet chains are fastened to the links or fasteners and/or equipped with a metal plate with a magnetic reaction in contact with the magnetisation circumference. The circumference or crown can receive two chains, one of which is completely floating; the device bathes in a fluid bath; a central pinion prevents the two chain strands from coming into contact and driving.
