A tower ( 1 ) for wind power installations, on which at least one rotor ( 2 ) that can be driven by wind can be rotatably supported, has an especially low mass relative to its load-bearing capacity, stability, and rigidity, if it has a tower portion ( 3 ), tapering toward the top, with a bulging outer wall ( 4 ) that is convex in longitudinal section. |
