Generating electricity from Tidal Fluctuations

From the smallest home generator, to the largest Fossil-Fuel/Nuclear Power Plant, there is a common goal --produce a Force/Torque to turn the shaft of an electric generator. Shafts are turned either by Steam Turbines, or Gas, LNG, Diesel, etc. engines, collectively referred to as “Prime Movers.” The use of those fuels to power Prime Movers, is the cause for all the growing climatic, pollution, quality of life and economic concerns, for our planet and its inhabitants.

Nature has provided us, through strictly the benign rise/fall of the tides (there is no interest here in the kinetics of currents/wave action), access to two forces of unimaginable magnitude -- available globally. Acting on a floating body (e.g., a barge, ship or constructed platform), a receding tide produces a downward force, up to the full weight of a suspended body. Similarly, a rising tide up to the weight of the body.

The goal then is to harness the two vertical and linear forces of the tides, to drive generators on land, cost and pollution free. Achieving that goal, negates the use of fossil/nuclear fuels for many generators, as well as contributing to the National Grid.

Two simple mechanical machines have been designed and recently patented -- kindly navigate to the Main Menu for their description.

The system installs at the water’s edge. The only component which touches water, is the floating body W. All others are on land, avoiding sea water fouling and maintenance issues.

W and the compound gear train are completely arbitrary and are determined by the generator HP/Torque/KW specifications. Depending on size, W and the DCS may be cloned into a number of smaller, independent systems. A hybrid system can include solar panels atop the platform, avoiding a costly land acquisition.

Potential Applications, Markets, Benefits and Social Implications

-Vertical and Linear Tidal motion is a constant, predictable and inexhaustible source of clean energy, 100% pollution free with no fossil fuel emissions or nuclear waste issues.

-The DCS is modular, modifiable, transportable – extremely small land footprint.

-Impervious to CME or EMP radiation.

-Benign with respect to the environment -- noiseless.

-Boost U.S. steel production, new industry, exporting, construction jobs, engineering, computer tech…

-Small systems provide rapid access to electricity for coastal villages/communities, islands or input to existing electric grids with larger/multiple systems – fraction of cost of conventional plants. Charge electric car batteries cleanly rather than by fossil fuel sources.

-Tidal Energy is cost free in contrast to the cost of producing & transporting fossil/nuclear fuels.

-Floating platforms optionally become revenue generators (fishing, docking, pool, sports, food, fuel etc.) nullifying construction costs.

-Tens of 1000’s of idle vessels using small dockside DCS with common attachment, input to the National Grid continuously –possible elimination or curtailing of some existing plants.

-Military: Opportunity for enormous energy savings, supplying power to remote/desolate Post locations. Supply ship doubles as the floating weight.

-Opportunity to provide Jobs and pathway out of plight of inner cities.

10

-DCS, LCS systems use strictly reliable rise/fall of tides -- no interest in randomness of wave action or currents.

-DCS, LCS systems become “Ambassadors of Good Will” for U.S., bringing electricity to coastal villages, devoid of energy.

Directly Coupled System (DCS)Prototype

Front Rod (connected to floating weight) drives gears on receding tide.Rear rod on rising tide. Both connect to driver gears. Rods suspended over water attached to floating W, all other components are land base, unaffected by salt water fouling.

Simple series of gears step up rpm to generator shaft. Replace with arbitrary set of higher gear ratios to reduce axles and/or increase rpms.

Generator supplies electricity to town/community free, complements of a rise and falling tide.

Impossible to demo a shoreline section here. Simulate with heavy box shown. There are no batteries/electrical sources. The slow linear Rise/Fall of the tide converted to rotational motion at the generator, lighting the community, cost and pollution free.Altering gear ratios for desired rpm and adjusting rods for desired torque, scaling up gives us a full scale DCS.
