Abstract
The present invention relates to a method and apparatus for power generation which comprises a first cylinder and a second cylinder, a first float member and a second float member disposed in the first and second cylinders, respectively, and a lever arm pivotably disposed above the cylinders, the ends portions of the lever arm being operatively connected to the respective float members. The lever arm contains weight members and defines a path for guiding the weight members to traverse the lever arm between the end portions. An inlet and outlet is provided for introducing and removing water into and from the first and second cylinders, the water being supplied from a dam whereby when the water is introduced into the first cylinder and simultaneously removed from the second cylinder, the first float member is caused to rise in the first cylinder and the second float member is caused to fall in the second cylinder. This causes the lever arm to pivot about its axis which, in turn, causes to weight members to relocate from one end portion of the lever arm to the other end portion thereof so that the out-put force resulting from the action of the lever arm alternating up and down such as…
