PCT No. PCT/JP89/00946 Sec. 371 Date Dec. 7, 1990 Sec. 102(e) Date Dec. 7, 1990 PCT Filed Sep. 19, 1989 PCT Pub. No. WO90/03516 PCT Pub. Date Apr. 5, 1990.A tidal power generation apparatus includes a first group of containers fixed in plural piles in a natural sea having a tidal difference in sea level height, which containers are spaced in parallel to one another at fixed intervals, each container of which is opened at a lower side thereof and is capable of holding air therein, a second group of containers fixed in plural piles in tideless water within an artificial dam, which second group of containers are spaced parallel to one another at fixed intervals, each container of which is opened at a lower side thereof and is capable of holding air therein, and air pipes providing communication between respective containers of the first group in the natural sea and respective containers of the second group within the artificial dam. With the apparatus, the energy in a tide is collected in the form of energy in compressed air created by water pressure at high tide. The compressed air is stored within the artificial dam and, at low tide, is transferred to a container situated at a relatively deeper position in the natural sea to obtain compressed air of even larger energy at the next high tide. Repetition of the above steps enables gathering of tidal energy otherwise dispersed over a wide area.
