<p>Apparatus for providing motive power comprises first and second communicating columns (10, 14) of liquid, the liquid in the second column being substantially the same as in the first column but containing a finely divided material to increase its specific gravity relative to the liquid in the first column, means (28) for maintaining the finely divided material in suspension in the second column, whereby liquid height in the respective columns is different, so that liquid from the first column overflows into the second column, means for converting energy from resultant movement of liquid into motive power and means (26) for returning the liquid to the first column.</p> |
