Energy derived from tidal or river flow energy units 17, solar cells 15 and wind driven devices 16, is fed to a control centre 14 and may be used to drive a block 10 up guides 11 to store the energy. Subsequent lowering of the block can be used to release energy. The block may comprise a container which may be filled with rainwater when in its raised position and drained in its lowered position. The block may be raised by drive motors located thereon and driving pinions engaging racks on the slope. The block 10 may be large enough to grow crops, graze livestock, and/or provide a recreation park, tourist attraction and hotel. Another aspect of the invention (Fig. 5) provides an underground structure 20, (such as a nuclear shelter) the structure being encased in puddle clay 26, to seal the structure and prevent water or any other liquid from entering if cracks in the structure should occur. An accommodation chamber 20 is connected to an access shaft 22 via a tunnel 21. <IMAGE> |
