To provide a power generation apparatus easily generating electric power without environmental load, with very simple facility and device and at low cost, and basically, regardless of locational conditions.

A plurality of floating devices having blades are flown utilizing wind power. The floating devices are linked with generators installed on a ground side through wires. Along with vertical motions of the floating devices, rotation shafts of the generators are forced into rotation through the wires, so that the electric power is generated. Therefore, the generating set can easily generate the electric power without environmental load, with very simple equipment and device at low cost, and basically, regardless of locational conditions.
