HUG Slab Wave

Slab Wave Potential



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)

Spur Dikes & Rock Vanes

Spur Dikes increase Kinetic Energy

Malawi Kinetic Energy HUGConstructed rocky shoals are used to divert water away from the bank and build a concentrated faster flow.  Spur dikes or rock vanes are used to narrow a widened channel of rapids in order to increase the velocity of the flow. Rock and stone walls are less costly than concrete walls.

Why increase the Velocity of the Flow?

Let’s look outside the box.

Is there a better way to increase the velocity of the flow and thereby reduce the size of the system by a factor of eight?
The HUG adds over three times the increase of velocity created from its Vortex. The turbine’s power is proportional to the cube of its average velocity. Thus, a doubling of the average speed of the flow results in an eight-fold increase in its power, which results in the lowest cost: $0.01/kWh.
The resulting kinetic energy (KE) would be increased by a power of three: v³ to 6³/2³or 27 times. The 4 knot (2 m/sec) current becomes 6 m/sec in the HUG and the KE increases from 50 kW to 1350 kW for 20,000 homes instead of 500 homes.
{KE (Kinetic Energy) = .5 x Area x v³ x .35 (efficiency)}
The HUG can be configured in arrays of much larger capacity – potentially hundreds of megawatts.

Here is a big bonus.

HUG Energy System

A floating HUG  Helical Turbine System will capture the kinetic energy from the current. No dam required.  It wouldn’t bother the fish.


The Pump HUG uses the physics of the vortex to create a spiraling motion to accelerate the flow of fluid  in order to generate electricity between two to four times because of the vortex inside.  The resulting kinetic energy is increased to the power of three, so the real increase is 2³ to 4³ or 8x to 64x compared to any kinetic system placed in the flow without the advantage of the VORTEX.

 Kinetic hydro power is dam-less hydro power that is converted from energy found in the flowing water currents of oceans, tides, rivers and man-made channels or conduits. Free Flow systems are turnkey renewable energy solutions that employ underwater turbines to generate electricity from the natural water currents. The systems do not require dams, impoundments or major civil works. They operate automatically, fully underwater and invisible from shore.
