Among other things, for wind-driven generation of electricity, a main shaft is rotated by a wind-driven rotor. A wheel having a diameter of at least meters is mounted to rotate with the main shaft. An electrical generator is driven by the wheel. A yaw ring defines a plane around which the main shaft and rotor yaw. The wheel intersects the plane of the yaw ring. In some aspects, the wheel, shaft, and electrical generator can be housed in a nacelle. The nacelle can be supported by a structure that includes at least three legs that define a lower tower that is relatively broad at its lower end and rises to a relatively narrow waist, and a nacelle support that is relatively narrow at its lower end where it is attached to the waist and relatively broader at its upper end where it supports the nacelle. |
