 The South Africa Wave Energy Potential

HUG Wave Energy

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

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

HUG Wave Energy Now enter a new use which is more profitable: the creation of electricity. Now it makes sense to spend over $25 million on the project because of a very lucrative return on investments: 19%/year in first year to 105%/year thereafter.

Waterfalls that Empty into an Ocean

OCEAN WATERFALLS

65 MW is a Huge Potential!

THE POWER OF GRAVITATION

The power of ocean waterfalls is possible because the water is traveling at 26 mph at the foot of waterfall:

Jeongbang Waterfall in South Korea:  23 m (75 ft) high: 

Six Helical Turbines at three levels: 18 HUG Turbines

(Final Velocity= 2 x a x s (distance)

Acceleration = a = g (acceleration of gravity)= 9.8 m/sec

Final Velocity = 12.5 m/s for 8 m distance (s)

  1. Initial Power of First Set of Turbine installed at 8 m level

KE = ½ x  A x V ³ x efficiency (A = area swept; Velocity)

                     at One Third of the crest of a waterfall

 One Third Power of the Helical Turbine

    = ½ x 3.26 m² x (12.5 m/s)³ x .35 = 1,100 kW/turbine x 6 =6.6 MW

Final Velocity = 17 m/s for 15 m distance (s)

2.  Power of Second Set of Turbine installed at 15 m level

                     at Two Third of the crest of a waterfall

Two Third Power of the next set of 6 Helical Turbines

    = ½ x 3.26 m² x (17 m/s)³ x .35 = 2,800 kW/turbine x 6 =16.8MW

3.  Final Power of Third Set of Turbine installed at 23 m level

                     at the  Bottom of the crest of a waterfall

Full Power of the last set of 6 Helical Turbines

    = ½ x 3.26 m² x (23 m/s)³ x .35 = 6900 kW/turbine x 6 =41 MW

Total Power of 18 HUG Turbines: 65 MW without the Vortex

160 MW is a Greater Potential!

THE POWER OF THE VORTEX

The HUG Funnel Prototype

The Velocity in the flume of the HUG is four times faster
The Velocity in the flume of the HUG is FOUR TIMES faster.

 In additon, a whirlpool pathway of the HUG creates a vortex.

The Velocity in the flume of the HUG is four times faster than placing the turbine directly in the path of the waterfall.

At three levels of HUG at 8 m, 15 m and 23 m, the velocity of the flow is interrupted by the HUG helical turbine. 

(Final Velocity= 2 x a x s (distance)

Acceleration = a = g (acceleration of gravity)= 9.8 m/sec

Final Velocity = 25 m/s for 8 m distance (s)

Initial Power of First Set of Turbine installed at 8 m level

Kinetic Energy = ½ x  A x V ³ x efficiency (A = area swept; Velocity)

 at One Third of the crest of a waterfall

 One Third Power of the Helical Turbine

    = ½ x 3.26 m² x (25 m/s)³ x .35 = 8,900 kW/turbine x 6 =53.5 MW

This power repeats itself at three levels: 53.5 MW x 3 = 160 MW
