Ocean Wave The Figure 29 arrangement is more preferable for smaller vessels onaccount of the forces generated in the second. In a second aspect, the invention comprises power generating apparatus compris ing apparatus as aforesaid supported on a support structure with one or more said vanes adapted to be located in a said fluid flow, whereby said vane or vanes can be oscillated by said fluid flow, and wherein said means to harness movement Is coupled to said vane or vanes to convert said movement into useful energy.

The remote end of the rod 29 is pivotally coupled to the circumference of a first wheel 30. A rod 31 is pivotally connected at its ends to the arm 23 and a point on the circumference of a second wheel 32. The two wheels 30, 32 are interconnected by a belt 36 so that the wheels are constrained to be driven in the same direction. Alternatively, the first vane may be adapted to be oscillated by drive means whereby to produce a propulsive effect. The sec- tor surfaces may therefore be toothed, ribbed or otherwise fashioned to enhance driving contact between them. There may be as many sets of vanes/hydrofoils as can possibly be mounted on the A- frame but still under water. These rods are also pivotally coupled to main levers 333-336 symmetrically mounted for pivotal movement about the main bearing axis 380 (Fig 38) on the cross member 337. Therefore, as the pedals are turned the main levers 333-336 oscillate about the main axis 380 in a scissor motion.

In essence it consists of a pair of gears 360 mounted for lateral movement relative to the main axis of the chain 361. This varies the relative lengths of the bights of chain extending between the pedal mechanisms and thereby adjusts the rela- tive phase between them. In all of the prior art approaches to power generation by using the energy in wa ter and/or tidal flow there are difficulties in achieving adequate or even design efficiencies and in ensuring that the equipment does not have to be located in positions where main tenance becomes a serious issue.

The mechanism is similar to that described in Figure 1, so it will not be described in detail here but basically, the Figure 1 mechanism on one side of the wheel is repeated on the opposite side, the mechanism having an additional set of arms to transfer the drive to the second hydrofoil rather than having a separate set of arms or rods coupled directly to the same one wheel.

Since the wheel 30 is 90 de grees out of phase with wheel 32, it will create a cycle which is 90 degrees out of phase with the displacement of the foils, that is to say, a cosine relationship. If a foil moving in the way previously described is placed in a current of water, it will create lift in a direction depending on its orientation. In preferred embodiments, the foil mechanism can be such that the levers operat ing the leading and trailing edges of the foils are slightly out of phase so that, in some posi tions, the foils are at right angles to the direction of flow when they pass through the mid dle of their cycle. The trailing edges of the vanes or hydrofoils are fixed to the ends of these.
