LIGHT SHIELDING DEVICE AND LIGHT SHIELDING METHOD
First Claim
1. A light shielding device, comprising:
- a shielding member configured to shield a spectrum of sunlight at a predetermined altitude so as to change weather,the predetermined altitude being a high altitude no lower than 100 m above the ground, and the shielding member having a function of reflecting and radiating a part or all of sunlight to itself toward a cosmic space; and
a buoyant force imparting unit configured to impart buoyant force to the shielding member, the buoyant force being imparted in a direction opposite of an own weight of the shielding member,the buoyant force imparting unitincluding a plurality of buoyant members provided for the light shielding device in a distributed manner and each filled with gas lighter than air, andbeing configured to maintain the shielding member and an object that is engaged with the shielding member in a floating state in which the shielding member and the object are in a non-contact state with a surface of the ground, whereina part or all of the buoyant members constitute a main body of the light shielding device.

Abstract
Provided is a large scale light shielding device and a light shielding method for controlling weather. A light shielding device 1 includes a shielding member 11 that shields a part or all of spectrums of sunlight, a buoyant force imparting unit 13 having buoyant members 41, and a drive mechanism 15. The shielding member 11 includes, in order to shield the part or all of the spectrums of the sunlight, a light shielding unit 35 and a light transmitting unit 37. The drive mechanism 15 includes a driving unit 21 that settles or changes a position of the light shielding device 1, and a controlling unit 25 for the driving unit 21. Buoyant force is produced by the buoyant members 41, and imparted to the light shielding device 1 in a direction opposite of gravity due to an own weight of the main body. A magnitude of the buoyant force produced by the buoyant members 11 depends on a magnitude of gravity acting on the gas that is pushed aside by the buoyant members 11, and it is possible to cause the light shielding device 1 to float.

13. A light shielding method using, in order to change weather, a light shielding device having a shielding member configured to shield a spectrum of sunlight and a buoyant force imparting unit configured to impart buoyant force to the shielding member to put the shielding member into a floating state,
the shielding member being configured by a film material, the floating state being a situation in which the shielding member and an object that is engaged with the shielding member are in a non-contact state with a surface of the ground, the buoyant force imparting unit including a plurality of buoyant members each filled with gas lighter than air, the plurality of buoyant members being provided in a distributed manner, and constituting a part or all of a main body of the light shielding device, and including gas adjusting unit configured to individually adjust an amount of the gas lighter than the air, the method comprising a step of imparting the buoyant force to the shielding member while balancing between the buoyant force of the plurality of the buoyant members provided in the distributed manner and own weight due to gravity of the main body of the light shielding device at corresponding portions by individually adjusting the amount of the gas lighter than the air filled in each buoyant member with the gas adjusting unit.
