Abstract
ABSTRACT
The development of surface water wave power, as a source of energy, has made little progress in the last fifty years, due mainly to the high cost of converting intermittent energy into a more sustainable form. Two serious "prior art" projects, the British and the Japanese are examined in the "Disclosure".
A model of a SURFACE WAVE DRIVEN GENERATOR is proposed which uses economical small scale and presently developed technology. Its distinguishable features from other inventions may be summarized as follows:
- the concept of this machine implicitly challenges the notion that large industrial hydroelectric type of installations offer the ideal model for a successful development of wave energy. Instead, this is better achieved by smaller installations, which are capable of meeting the household needs of poor populations living off the coastlines of third world countries blessed with abundant, albeit unutilized wave energy.
- this invention makes full use of two devices [flywheel, compressed air]
capable of storing energy in order to correct the intermittent nature of wave power. In this respect, the most efficient energy storage device, the flywheel, plays the predominant role.
- the performance and efficiency of the compressed air process are increased through a scientifically controlled solar exposure of the walls of the compressed air container.
- operational costs are substantially reduced if the sensitive and vulnerable parts of the wave driven machine are stationed ashore where they are easily accessible for repairs and surveillance.

Claims (4)
1. A system or linkage of small scale and presently developed technology capable of converting surface water wave energy into electricity and which comprises an air compressor unit, a compressed air reservoir or chamber and a power unit composed of a flywheel and an electric generator, each unit interacting and working together.
2. An air compressor unit comprising a concrete base resting on the sea floor on which stands a group of heavy rubber bellows connected by rods to an elongated rectangular float moving freely and vertically along two guiding poles implanted at the distal ends of the concrete base and responding to the vertical motions of sea waves, thus compressing air in a reservoir located ashore and to which the air compressor is connected by flexible hoses.
3. An air reservoir which in addition to storing energy in the form of compressed air, is made to increase its air mass pressure through the solar exposure of its walls by orientation and available chemical or optical means.
4. A power unit comprising a heavy flywheel and an electric generator driven by a stream of compressed air directed against the bladings of a rotative impeller which conterbalances and smooths out the intermittent wave pulses, causing the flywheel and the generator to spin at an equable speed, thus doing away with the traditionnal coupling up of a generator with storage batteries.
