Abstract: A system (100) for generating electricity comprising—at least one structure (1) defining an upper support surface (11) and a lower support surface (12); —a plurality of cranes (2, 2a, 2b, 2c, 2d, 2e) adapted to move a plurality of bodies (3) from the upper support surface (11) to the lower support surface (12), and vice versa; wherein each crane (2, 2a, 2b, 2c, 2d, 2e) is provided with—gripping means (21) adapted to grasp a body (3) of said plurality of bodies (3); —and a device (4) connected to the gripping means (21), adapted to transform into electricity the kinetic energy of a body (3) grasped by the gripping means (21), which moves, in particular substantially vertically, under the effect of gravity towards the lower support surface (12).
Abstract: A building system for buildings comprising at least two stories, provided with: —a plurality of first portals (3, 3?) adapted to be arranged along at least two mutually parallel vertical planes and to be fixed to a base (2); —first connecting beams (15) for connecting a first portal (3?) and the next first portal (3) arranged along a same vertical plane of said at least two vertical planes; first floor panels (17) adapted to transversely connect together both the first portals (3, 3?) arranged along the at least two vertical planes, and the first connecting beams (15) arranged along the at least two vertical planes; —a plurality of second portals (40, 40?) adapted to be arranged along said at least two vertical planes, each on top of a respective first portal (3, 3?); wherein each first portal (3, 3?) and each second portal (40, 40?) are monolithic and substantially consist of at least two pillars (4) parallel to each other and of a beam (5, 5?), arranged transversely on top of the pillars (4), each pillar (4
