2, a turbine 2,10 is housed inside one of the float sections, where it is protected from the elements. Thus the air compression system of each WECWAC can be networked to a single turbine. Indeed, as the number of WECWACs increases, smoothing will occur more and more within the interconnecting pipe work, and storage for smoothing may be less important. Valves are one-way (non-return) valves similar to those normally used In reciprocating compressors, and may be of the plate or poppet type.

1, compressed exhaust air passes through exhaust valves (not shown) in hollow piston 1.2, and then through the hollow piston rod 1.3 and single exhaust pipe 1.6. Evidently, alternate piping arrangements may be used to collect the compressed air. Once air pressure inside the cylinder builds up, the bumpstops will not be frequently used.
As waves build up, air is also compressed in the lower chamber of the cylinder. Once the system has ‘booted’ up, the bumpstops will hardly be used. If variable stroke is not used, delivery pressure from the WECWAC will drop substantially in small seas, making it extremely difficult to generate power efficiently. In so far as is 6 known, these and other prior art systems have not been manufactured or commercialized due to the impracticality of building and operating such devices. The other floating body is a central ‘spar’ located within the float.
In Fig. 1, compressed air is stored inside the hollow float 1.1, but it could instead be supplied to holding tanks located in other suitable locations. The cylinder is double-acting in that air is compressed in the upper chamber on the up-stroke and in the lower chamber on the down-stroke of. Tengo mucho dolor de espalda y estoy embarazada . Ideally, the output from each WECWAC is at a constant pressure, but the compressible nature of air means that this is not required. However, the use of the float as an air receiver is not essential. 1 and 1A. That is, the volume of compressed air (or any suitable gas) will be genially equal for chambers 8 and 9. However, in still water, the cylinder and spar (as designed) drift down as shown in Fig. The opportunity to transmit “raw power” via air means that the electronic components for controlling the process can be housed in a safe and clean environment.
For example, 40 MW can be transmitted via a 1.2 m diameter pipe over 1.5 km with a loss of less than five percent. It is generally known that the conversion efficiency of turbine-generators increases with site. It should be appreciated that the positioning of the cylinder is relatively independent of the stroking movement of the piston which is a direct function of the float, generally in phase with the waves. The relative movement between the apparatus parts is used to drive a PTO system. Therefore a major challenge is to find apparatus that will efficiently convert wave energy into a form that can be efficiently used, e.g., to drive an electric generator. This means that for waves of small amplitude, the maximum swept volume of the upper chamber 1.8 is reduced, allowing air to be compressed fully by the piston.
