Salmon Generator USPTO Patent 6,741,000 Copyright January 2011Ronald A. Newcomb (619) 501-1800
Old hydroelectric generators chop the water as it passes. 4% of the fish are chopped in each pass. 60% are disoriented and do not immediately resume migration. Predatory fish and scavenger fish wait at the bottom of the dam for chopped and disoriented fish to prey on. Old Technology Kaplan: Francis:
RBDD Screws This is one of two 35 foot water screws installed and tested at RBDD. Note the motor at the top of the screw which drives it. These screws were used as Archimedes designed, to lift water.
Project Salmon Run Newcomb’s generator is fish-friendly, killing less that 1% of the fish passing. Newcomb’s generator is a straight flow through system. Fish can pass either direction when conditions are right for the species.
Benefits Flow Through Design Reduced Maintenance Higher Efficiency Safe Fish Passage Will meet EPA & NMF requirements for the river habitat. Can be retrofitted into any hydro electric dams and fitted to small dams.
Small Dam Benefits Creates energy where none is now created Creates Bi-directional Fish Passage Allows communities to make use of very old structures that currently waste all energy stored behind each dam Restores fish passage and river flows.
The Generator A New, More Efficient Design for Hydroelectric Energy Production. Scalable to Any Size of Generator or Pump. Highly Efficient Motor/generator.
Hydro-Power Transformation 1 This image is from the DOE and shows one of many Hydroelectric generator configurations used today. Note the main components: Generator, shaft, and screw type propeller. Note also the required change in water direction. Newton’s laws tell us this change in direction causes energy to be wasted. Pay attention to the top, for the moment, let me show you one..
Hydro-Transformation Sidebar 1 Parker Dam Unit 1 Core Test Parker Dam, Lower Colorado River Basin, Lake Havasu Core Loop Test of Unit #1 November 2007
Hydro-Transformation Sidebar 2 We have all seen images of generators, let’s look inside. In this image, look to the top and bottom, Unit #1 is disassembled (top) and the armature is barely visible (bottom), let me show you what they look like...
Hydro-Transformation Sidebar 3 Generator Armature, this is upright so the primary turbine shaft extends well below the floor. Let’s look from underneath...
Hydro-Transformation Sidebar 4 “Ah, that’s why the 3D drawings look this way,” says you.
Hydro-Transformation Sidebar 5 Parker Dam Core Test: This is where the armature fits, note the platform used so we can stand in the generator during to core loop test (high power is run through those visible cables to test the stator (red). What do I mean “we?” you ask...
Hydro-Transformation Sidebar 6 “We” us, me! That’s the core during the test. What is below is what kills the some of the fish that pass through...
Hydro-Transformation Sidebar 7 Wicket Gates, in this case, above the Kaplan Generator blade, this is where the water flows into the turbine. In a Francis Generator, it would flow out here between the turbine and the gates the fish are chopped. In a Kaplan, it is below this where the blade either cuts them by direct force of the high speed blade, like a blender blade, ir traps them between the blade and the wall of the generator...Let’s continue with the thought experiment.
Review: Tranformation Now you understand what this illustrates, let me overlay it with a drawing I can manipulate, one I created with engineering software...
Hydro-Power Transformation 2 Here I have overlaid the previous image with a 3d drawing to simplify the illustration. Note the same basic components are in place. The generator, the shaft, the blade. I will evolve this picture.
Hydro-Power Transformation 3 This is the same image annotated to list the components.
Hydro-Power Transformation 4 Here we have replaced the screw type ‘propeller’ style truncated screw with a longer single auger type screw blade which gives more power because it has more surface area for the water to push against.
Hydro-Power Transformation 5 Now I have placed an outer cylinder around the screw. It is now a classical Archimedes screw. This is true devolution since exactly the opposite is how we arrived at the propeller.
Hydro-Power Transformation 6 Now we have Removed the shaft and placed the screw directly into the generator.
Hydro-Power Transformation 7 Lastly, we alter the angle of the screw and generator.
Different Configurations Many different configurations of the screw can be designed to increase the efficiency. Both radial fields (as you have just seen), and more efficient axial fields can be designed. While you conserve energy by not changing the general direction of the water during its passage (Ref: Newton’s Laws), the actual direction of flow is relatively irrelevant.
Proprietary Designs Patented Use of the Archimedes Screw. Patent 6,741,000 Driven by water pressure. May be used as a highly efficient pump. Proprietary motor/generator. New motor, high efficiency design. Higher weight-to-power ratio than other designs.
Pump Diagram Shows a screw with five modules (no magnets). Stackable to achieve desired results. Modules can be replaced. Unit can be scaled to any size pump/generator How does this solve the Salmon problem?
Solution to Dam Problems Upper Generator Passes Warm Oxygenated Water Lower Generator Passes Sediment and Cold Water Fish Can Migrate Up and Down Stream
Solution to Dam ProblemsConstant efficiency over the entire operating range means excess water can now be used to generate more power. Therefore, less water is wasted.
General Market Potential Adaptable to many water pump usages and reduces energy usage. Increases generator output with a more efficient design and more efficient use of water directionality, thus reducing energy loss per Newton. Adaptable to any size dam. Deep water currents such as the Gulf Stream become profitable. Any water down flow can be used including small water wheel dams.
