VAPOR EVAPORATION SUPPRESSION UNIT, VAPOR EVAPORATION SUPPRESSION APPARATUS, AND ARTIFICIAL FLOATING ISLAND
As a measure against the source of enormous energy of abnormal weather, the present invention suppresses vapor dispersion into the air due to excessive evaporation at the sea near the equator to mitigate disasters due to abnormal weather, to normalize atmospheric circulation, and also to make it possible to utilize the vapor by retaining water. Provided are: vapor evaporation suppression units 100 that are installed offshore and that suppress vapor evaporation from the sea surface; and a vapor evaporation suppression apparatus 200 that is formed by linking together the vapor evaporation suppression units 100. Each of the vapor evaporation suppression units 100 is formed from: a housing 10 that has four or three side surfaces and a top surface and in which a bottom surface is open; and a plurality of floats 7, 8, 9 that are attached to the housing 10. The interior of the housing 10 has a structure: that is divided into two layers, namely, an upper layer and a lower layer, by means of a guide surface, which is inclined so as to slope down toward one of the side surfaces; that allows vapor evaporated from the sea surface below the housing to be introduced into the interior of the housing; and that has a water retaining part capable of retaining, in a portion of the upper layer positioned at a lower section of the guide surface, water resulting from condensation of the vapor.
A water vapor suppression material may include grains obtained by (1) granulating a natural glue of plant origin, for being distributed over a water surface to suppress the evaporation of water vapor, or (2) forming a mixture of a natural glue of plant origin and a plant-based powder into a granular shape, for being distributed over a water surface to suppress the evaporation of water vapor.

Provided is a floating oceanic debris collection device capable of automatically collecting debris, suitable for use on the sea, and usable for a long period of time without the need for maintenance. A floating oceanic debris collection device 100 is a floating oceanic debris collection device having a substantially circular shape in plan view and installed on the sea to collect debris G floating on the sea surface S. The floating oceanic debris collection device 100 comprises a circular base 1 divided into a debris storage unit 3 on the inner peripheral side and a debris collection unit 2 on the outer peripheral side. The debris collection unit 2 comprises a blade 30 and an arm 20. The debris storage unit 3 comprises an inner peripheral float 50 and an outlet 60. The inner peripheral float 50 has an inlet 52 formed penetrating through a peripheral surface 50. The outlet 60 is formed penetrating through the top surface of the base 1. As the blade 30 on the debris collection unit 2 is blown by the sea wind, the entire base 1 rotates, and the debris G floating on the sea surface S is swept inward by the arm 20. Then, the debris G is introduced into the interior through the inlet 52 formed in the debris storage unit 3, so that the debris G can be removed through the outlet 60.

Provided is a device for recovering polluted air, with which it is possible to easily recover polluted air over a wide area and render the area harmless. This device comprises an air collection unit 10A, a main control unit 20, an emission unit 30, and a suction-side air pipe 40 and a delivery-side air pipe 50. The air collection unit 10A has a cover body 11A having an opening on the lower side thereof and a filter member 12 attached to the inside of the cover body 11A. The main control unit 20 has a pump 21 capable of drawing gas by suction and delivering same. The emission unit 30 has an air storage pipe 31 to be installed undersea and a plurality of exhaust nozzles 32 provided to the air storage pipe 31. The suction-side air pipe 40 connects the air collection unit 10 and the main control unit 20. The delivery-side air pipe 50 connects the main control unit 20 and the emission unit 30 so as to allow gas to move therebetween. The gas, being polluted air PA, is drawn by suction from the air collection unit 10A by the pump 21 and is delivered to the emission unit 30, and then is discharged from the exhaust nozzles 32 of the air storage pipe 31.
Provided are: a light concentrating unit that is capable of efficiently concentrating a large amount of sunlight; a light concentrating device that comprises said light concentrating unit; and an illumination device that is combined with said light concentrating device and radiates concentrated sunlight. This light concentrating unit comprises a plurality of lenses, namely, a main lens (11) that is a centrally disposed convex lens having a circular shape in a plan view, and an auxiliary lens (12) that is a convex lens having a non-circular shape in a plan view and disposed around the main lens. Sunlight incident to the incident surfaces of the lenses (11, 12) is converged upon a focal point (F) of the main lens.
Provided are: a water vapor suppression material that is capable of resolving root causes of meteorological disasters by covering ocean surface so as to allow moderate generation of water vapor while suppressing excessive generation of water vapor, and that has a low impact on the environment; and a production method therefor. By dispersing, over a wide area of water surface so as to cover the surface of a body of water, this water vapor suppression material produced by drying granules obtained by granulating a plant-derived natural glue or a mixture of powder of a plant material and a plant-derived natural glue, excessive evaporation of water vapor is suppressed while maintaining water vapor evaporation at an adequate level. Meanwhile, because only plant-derived raw materials are used, it is possible for those materials to be returned to the environment in the water.
