Abstract: A wave-powered pneumatic system for producing compressed air to be used for energy storage or power generation, comprising an elongated seawall extending parallel to the shore and at a distance out from the shore, upon which an air-accumulating structure is built. The air-accumulating structure is divided by partitions into a plurality of modules, each consisting of a plurality of stacked air chambers arranged one above the other. Each of the chambers is relatively shallow in the vertical dimension, and each chamber is closed on all sides except the end facing out to sea. A plenum chamber is connected to each of the air chambers by separate ducts having check valves which allow air to flow into the plenum chamber when pressure within the duct exceeds the pressure in the plenum chamber. The plenum chamber is connected to the air storage or power generating means.

Abstract: A vapor generator vaporizes a motive fluid which is used to drive a multivaned rotary expander. The expander is the prime mover for an electric generator which may be an alternator. Exhausted vapor from the expander (or if the expander is not being operated, vapor from the vapor generator) is passed through a heat exchanger where a fluid, e.g. air or water, is heated. This heated fluid is used for space heating. The expander may also be connected to drive the compressor for an air conditioning system. Alternatively, an electric motor may be employed for this purpose.
