Title:
METHOD AND APPARATUS OF EXTRACTING ENERGY FROM WATER WAVES TO GENERATE ELECTRIC POWER
Document Type and Number:
WIPO Patent Application WO/2019/064080
Kind Code:
A3
Abstract:
This invention relates to method and apparatus for extracting energy from water waves to generate electric power. The wave energy converter utilizes sea wave oscillations, from a land-based position. It comprises a land-based power take off apparatus (3) that is oscillated by waves conveyed to it by canal or tunnel. The canal has a funnel shaped intake (1) at the coastline, a wave control gate (9) positioned near the intake and a power take off apparatus (3) positioned inland across the canal with a float (8) that works pumping cylinders (7) that pump hydraulic fluid to turn an impulse turbine (5) coupled to an electricity generator to generate electricity. The canal depth is predetermined to float the float, of the power take off apparatus (3), at all tide levels. On the aft side of the float the canal traces a path looped back (4) to the fore side of the float to include extraction of residual wave power.
