Hawaii Wave Energy

The Hawaii Wave Energy PotentialHUG Wave Energy

The HUG Hawaii  Wave Energy is a game changer. It promises to bring electricity created from ocean wave energy to the ocean shores of Hawaii at a very low cost.

Hawaii would seem a natural site for such technology. As any surfer can tell you, it is blessed with powerful waves. The island state also has the nation’s highest electricity costs—largely because of its heavy reliance on oil delivered by sea—and has a legislative mandate to get 100 percent of its energy from renewables by 2045.

The following images are located along the  coast of Hawaii wherever there is a natural small bay. This type of topography reduces the cost of the reservoir.

OCEAN WAVE ENERGY

A slab is a piece of reef that sticks out in deep water or deep water sits behind it. Most slabs break in the same spot.  In the figure below, the HUG slab wave, 1, moves fast and hits a shallow reef, 4, at full speed. It lifts out of nowhere within seconds. HUG Slab waves are heavy reef breaks coming out of deep water and breaking in very shallow water. As a thick lip unloads on a shelf, the water doesn’t have anywhere to go but upwards overtopping into a reservoir with all their open-ocean energy intact. That energy gets focused as the depth suddenly decreases.

HUG Slab Wave

Acceleration = a = g (acceleration of gravity) = 9.8 m3/sec                                                                      (Final Velocity)2 = 2 x a x s

In the summer, the head of water is 1.5 m from water forcing through the automatic gates of the artificial reef:

Final Velocity = 5.42 m/sec for 1.5 m drop (s):

 In the winter, the head of water is 5 m from water washing over the walls of the artificial reef:

Final Velocity = 9.9 m/sec for 5 m drop (s) of the crest to sea level.

       Wave heights during storms may exceed 10 meters (33 feet)
