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

HUG Competition

To be the First Mover in Tidal Power

Innovation is usually geared toward improving efficiency or effectiveness. Efficiency innovations decrease the cost to market. For this reason, investors are not so much interested in the “new” aspect of innovation, as they are in the “improved” part.  HUG Tidal power is more than improved: it is an entirely new good.

What must be done to create new products, enhance market penetration, lock in customers and lower operational costs?

Often the risk and the costs associated with achieving competitive advantage is formidable

Developing new and unique products that are not easily duplicated by competitors: one provides more value to the customer, which in turn creates brand loyalty because having one’s name associated with a new product (much like snowmobiles have been called “SkiDoos”  for years).  One simply becomes the “go to” company as Wal-Mart did.

Enter the HUG!

None of the Present Technology use the Power of the Vortex, like the HUG.

  1. The Dam has inherent disadvantages:
  • The large size includes concrete construction involving high construction costs.
  • Each dam plant is very expensive because a custom-designed, one-off project.
  • Fish-passage facilities need to be provided to help fish bypass the power station.
  1. Investment in helical turbines has increased to US$257 million (Korea) in 2007. Kordi of Korea had planned its pilot turbines in ocean currents at Uldolmok. Korea have very strong currents up to 6.5 m/s.  They have designed 24 jackets (16m by 16m) along 3 lanes. The difference is that the helical turbines are not placed in a vortex of a pathway like a HUG. See Figure 1.
  1. Ireland’s OpenHydro has spent $2.2 million on their propeller system in the Bay of Fundy to date. This company has not really reported any news about their new invention, since they installed it several years ago. The total device weighs 360 tons, which is a large burden. The power density is 2.6 kW/m2. See Figure 2.   The HUG Power Density is an unbelievable 73.5 kW/m2.
  1. France’s Alstom Hydro Canada Inc. , having licensed Clean Current’s technology, planned to demonstrate its tidal turbine, which is in the form of a propeller. See Figure 3.  [Consortium Members: Emerson Electric Co.; Clean Current Power Systems Inc.;  Alstom Hydro France]
  1.  Verdant Power (SDTC support) is currently installing six Gorlov turbines in New York City’s East River. Each turbine will have a blade diameter of 16 feet and is rated at between 25–30 kW. Again, these turbines are simply placed in the path of a tidal flow.  The Power output at 2.5 m/s is only 168kW/turbine. The  power density is only 2.8 kW/m2.  [Consortium:  Consortium Members:Mohawk Council of Akwesasne;  St. Lawrence College of Applied Arts and Technology;  St. Lawrence River Institute of Environmental  Sciences; Ontario Power Authority; Niagara Region Ventures Fund]  See Figure 4.
  1. United Kingdom’s Atlantis Operation (Canada) (SDTC support): 1 MW AR1000 propeller turbine which is immense and very heavy in size. [Consortium: Lockheed Martin Canada (LMC);Irving Shipbuilding] See Figure 5.
  1. Canada’s Clean Current Power Systems Inc.(SDTC support): propeller turbine 65kW needs a 5.5 meter depth and an unlikely stated speed of the river of 3.0 to 3.5 m/sec., unlike the 1 meter depth of the HUG with a more likely river speed of 2 m/s. [Consortium:  EnCana Corp.;  New Energy Corporation Inc.; Tidal Power Generation] See Figure 6.
  1. Canada’s New Energy Corporation Inc.(SDTC support): using superior four helical blades producing a small 5kW and much larger 25 kW system designed for high velocity of 3 m/s. Again this system relies entirely on the affluent flow of the current…unlike the HUG, which uses a system to increase this to a laminar flow thereby creating a zero friction boundary layer along the inside lining of the HUG.  [Consortium: Nova Scotia Power Inc.] See Figure 7.
  1. R.E.R (SDTC support)is installed at the Lachine Rapids near Montreal. Unfortunately, their system has to be built as big as the Kordi system in Korea: 2.3 kW/ m2. The maintenance on such a large structure will be a huge expense. [Consortium: ABB Inc. (Canada); Agence de l’efficacité énergétique du Québec]  BANKRUPT! See Figure 8.
  1. The prototype of a VLH system, developed with a French partner by Turbines Novatech-Lowatt Inc. in Beloeil, Quebec. Once connected to the network, the first VLH turbine has been submitted to exhaustive commissioning tests. (Area = 15.9 m2) The weakness of this system is the low velocity (2 m/s. The maintenance on such a large structure will be a huge expense. See Figure 9.
  1. The most advanced companies from a commercialization standpoint are two European companies: Marine Current Turbines of the UK (cost unknown) and Hammerfest Strøm of Norway(Investment to date: $13.4 million). Both of these companies use a propeller style turbine, which have received significant support from their respective federal governments. In contrast, the HUG has negative pressure or a suction action at its entrance. Also, a propeller style turbine, which is used by the competitors, has a lower efficiency of 20% compared to the helical turbine’s 35% efficiency.  See Figure 10.
