NOVELTY - The floating chamber includes a solar battery which generates electricity, and a steam separator which condenses the steam and forms water. Using the electric power generated, electrolysis is performed and water is split into oxygen and hydrogen. A hydrogen storage unit stores the liquefied hydrogen.    DETAILED DESCRIPTION - Globular solar floating chamber (Sa) with diameter of 200 m, disc floating chamber (M) with a diameter of 200 km, another disc floating chamber (L) with a diameter of 2000 km are made to float in air by injecting gas lighter than air inside. Helium is enclosed in the principal portion of airtight space within the outer wall. A direction information unit detects direction of solar light and measures the time. A position controller controls the position of the energy station based on detected information by direction information unit. The floating chamber is controlled such that it is in the position where it can receive maximum solar light. The outer wall is made strong with resin reinforcement and carbon fibers such as carbon fiber reinforced plastics. A pillar is provided passing through the center of the floating chamber. The axis of the pillar is maintained vertically by providing an elevation unit to inside of pillar. The distance between the lower surface of floating chamber and upper surface is set to H. The top diameter is set to D. The floating chamber is thus made such that H is less than D. A drive unit includes motor which rotates the rotor wings arranged below the floating chamber and sends it into space. A habitation space is provided in which a human being can reside. Artificial soil is prepared such that plants can grow. The water and solar energy available is used for supply of plants and human beings. Water sprinkler is provided to sprinkle water on the artificial soil.    INDEPENDENT CLAIMS are also included for: (i) Solar power construction method that involves arranging different types of power chambers such as small disc type, large disc type etc in space as floating chambers. The small circle board is installed as a nuclear structure in air and the globular chamber as a material handling missile. The material handling missile reciprocates to carry out the conveyance of the terrestrial material or the nuclear structure to build a large disc type energy station. (ii) Hydrogen handling method involves conveying hydrogen stored in hydrogen storage unit by hydrogen conveyance missile. The globular chamber floating in the air is made to contact hydrogen conveyance missile. The hydrogen storage unit is mounted on the globular chamber. The hydrogen conveyance missile is landed at the required ground after appropriate time. Hauled hydrogen is sent to the hydrogen storage plant.    USE -   For generation of hydrogen in space.    ADVANTAGE -   Electric power is generated at cheap cost using the floating chamber. Using the electric power liquefied hydrogen is obtained by electrolysis of water.    DESCRIPTION OF DRAWING - The figure shows the solar power generating system. (Sa) Globular solar floating chamber; (M,L) Disc floating chamber.
