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 = 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)
- 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
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 = 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
