Abstract: The invention relates to a method for constructing buildings having a reticular structure and to a building constructed using said method. The method comprises the steps of: erecting a set of columns (1, 2, 3, 4) that form the vertical supporting structure, on foundations or piles; arranging, in a lower zone of the structure (100), a heap (5) with fully constructed floor modules (6) inside the space defined by the columns (1, 2, 3, 4) and in the same vertical order as the definitive order planned for each of the floor modules of the structure (100) forming the building; raising the floor modules (6) by means of elevators, to place same in their definitive positions at corresponding heights; and joining the floor modules (6) to the columns (1, 2, 3, 4) by means of screwing, welding, riveting or an equivalent system.

Abstract: The invention relates to a system for the production of hydrogen from sea water. Said system comprises a ship (1) provided with sails (2) for capturing wind in order to move the ship, at least one turbine (3) which is disposed underneath the ship in order to remain submerged in the water and which is made to rotate by the action of the water flowing via same when the ship (1) moves in relation to the water, an electric generator (4) adapted to convert the rotation of the turbines (3) into electrical energy, a system (5) for generating hydrogen from the electrical energy generated, and hydrogen storage means (6). The sails (2) have a profile that can be configured between a folded non-operative position and an unfolded operative position, wherein they determine the profile of the rail and therefore the aerodynamic surface for contacting with the wind.
