Sourcetainable Jetty Joule
Operates by a “slapping” mechanism that utilizes inbound wave strikes against a primary hexagonal diaphragm, which creates a pressure difference across the (lead) primary diaphragm and (lag) secondary diaphragm. When the sea wave intersects the Jetty Joule, the force of the sea wave compresses the hexagonal diaphragm and forces the internal fluid to the opposing diaphragm. This hydraulic fluid is routed through a turbine before entering the opposing diaphragm and in that process generating electricity. Wave slap will occur for a few seconds and then, when pressure is released, fluid will find equilibrium thus recharging primary diaphragm for another wave slap. The diaphragms are imbedded in approximately 60K lbs. of precast concrete, which is held in place by 16” diameter pilings in eight to twelve feet of water. The Jetty Joule could also act as a type of erosion control or possibly jetty defenders.
