<p>A generator is described including: a support; a rotor; the rotor is coupled to the support by way of a pivot mechanism; the pivot mechanism includes a rotating portion which rotates about a fixed centre of rotation; the pivot mechanism allows translational movement of the rotor with respect to the rotating portion during rotation of the rotor to thereby modify the effective centre of rotation of the rotor; and a control arrangement for controlling the effective centre of rotation of the rotor; the control arrangement being configured to control the centre of rotation to cause the rotor to be rotated under the influence of gravity.</p> |
