Abstract: A cooling system which comprises a cooling fluid to cool a body or object, and at least a cold transmission surface in direct or indirect contact with said body or object. It is characterized in that it comprises at least a device for collecting and storing frigories that can receive a preset quantity of cooling fluid from an external charging device, store said frigories and transmit them at a preset velocity and temperature to said cold transmission surface. It is obtained a system in which it is not necessary to use a cryogenic deposit forming part of it, so that the security is enhanced and the cost is reduced.

Abstract: Device (1) for cooling a body, which comprises a garment (2) in contact with said body, a coolant for cooling said garment (2) and means of storing said coolant, said garment (2) including a layer of conductive fabric with a thermal conductivity suitable for transmitting by contact the heat to said coolant stored in said storage means and is characterised in that said coolant is a cryogenic fluid and in that said cryogenic fluid is liquid nitrogen (4). The device possesses high coolant power, since it permits the use of coolant substances at very low temperature, adapts easily to the body on which it is applied and is very safe.

Abstract: Includes at least one floating body (1), and is characterised in that includes a device (2) fitted inside said body (1) for transforming the movement of the floating body (1) into pneumatic or hydraulic energy and means for transmitting the energy to dry land or to a fixed structure. An energy-generation system is obtained thereby with a manufacturing time and cost lower than the systems currently known. Moreover, the fact that the transforming device (2) is fitted inside the floating body (1) means that it is protected against corrosion caused by the water, against sharp movements caused by marine currents and against other possible outside agents which might harm or damage any of the components which make up the device.
