Preferably, hub extends in generally a horizontal direction so that the belt's straight sections are substantially horizontal. Sails extend from the belt loop so that fluid movement (wind or water) pushes the sails and causes the belt to move and thus cause the pulley to rotate. The pulley is connected to the electric generator to provide electricity. Preferably, the sails are extendable when traveling with the wind and collapsible when traveling into the wind. Also preferably, the hub assembly is capable of rotating about a substantially vertical axis and tilting about a horizontal axis.
