Definitions

  • the present invention relates to a method for production of energy from a stream of water, in which a rotational body rotates or turns and drives a generator for production of said energy, as given in claim 1.
  • the invention also relates to an apparatus for production of energy.
  • the invention also relates to applications as described in claim 6.
  • the aim of the present patent application is to be able to use a new source of production of renewable, electric energy.
  • the ocean regions of the world represent enormous amounts of energy.
  • To use existing tidal and ocean currents for production of electricity is well known, by placing waterwheels, water turbines and the like, directly into a tidal stream that is pulsing back and forth, and in many different ways.
  • the present invention has a completely different starting point.
  • the present invention aims to utilise the power potential in the tidal wave that is transmitted around the globe in a way which has not been proposed previously: When the tidal wave meets land formation, permanent time disturbances in the tidal wave and/or permanent changes in the tidal pattern arise.
  • Such permanent changes in the vertical movement pattern of the body of water can be used for generation of power by a technically constructed horizontal connection through the land mass between the water bodies.
  • Paddle wheels driven by the tide have a shorter history.
  • the oldest version is an indirect use of the tidal water.
  • a dyke with a lock gate is established in the tidal zone.
  • the lock gate is automatically shut when the tide turns.
  • the stored water is released through a duct and this drives the paddle wheel.
  • the oldest find of such tide mills was made at Strangford Lough in Northern Ireland and dated to 787 AD.
  • the first paddle wheel driven directly by natural tidal streams was built in Bergen, Norway in 1599.
  • a paddle wheel and a mill were constructed on a bulwark. Walls led the tidal water into the water duct that drove the paddle wheel.
  • the principle was so sensational that the Danish-Norwegian king Christians IV, travelled from Copenhagen to Bergen the same year to study the installation.
  • the aim of the present invention is to use paddle wheels in a water duct for the operation of electricity generators. With the present invention, this ancient principle is put in a completely new and epoch making connection.
  • Modem tidal power stations also build further on the principles from the two historical main types that are described above:
  • the present invention has nothing in common with the two above mentioned systems. Instead, one aims to create new, artificial, tidal streams in water ducts inside tunnels or tunnels/pipes. These artificial streams of water can be calculated and controlled, they can be used in their entire length and, for example, be maintained on dry land inside a rocky ground.
  • JP2000018146 is based on tidal water being led into a low-lying sea and then back out again, and particularly both at the Mexican east coast and at the Mexican west coast. It is possibly also suggested to connect a low-lying sea in South Mexico to both the Pacific Ocean and the Gulf of Mexico. Water from the high tide in the Pacific Ocean can then be stored there and be released at low tide in the Gulf of Mexico.
  • the British publication GB-2298004 is based on a concrete location in the Orkneys, the Churchill Barrier, an artificial barrier built as a defence installation. There are different tidal patterns on each side of the barrier. It is a wish to utilise this by setting up a turbine.
  • the patent also mentions other artificial barriers in the area where this can be set up. It is also mentioned that this can be set up with a natural, narrow isthmus. It is possible to generate electric energy by the use of the patent GB2298004 at these locations. In reality, this installation utilises only an obstructed tidal stream of water.
  • the barrier ought to have a sufficient length to induce a time delay in the levelling out of said water levels as the tidal water falls and rises. It is indicated that a length of 1 kilometre is preferred.
  • US-2003/0192308 has consequently a completely different phenomenological and theoretical basis that one aims to utilise with the present patent application.
  • the present invention can be used in all places where natural conditions de facto create either permanent time differences in the same tidal rhythm, where natural conditions create permanent different tidal patterns or where natural conditions create both permanent time differences in the tidal cycles and permanent different tidal patterns. Economic considerations will decide if the patent shall be applied in one location or not.
  • the present invention is a.
  • the method according to the invention is characterised in that through a channel connection arranged between a landmass that defines a divide between two ocean areas with different tidal water cycles, a stream of water is provided as a consequence of the different ocean levels between the two ocean areas and leads to a phase displacement in the tidal water cycles of the ocean areas, and said rotational body is placed in the stream of water to provide said energy, as
  • the apparatus according to the invention is characterised by the features that are given in the subsequent apparatus claim 6.
  • a channel or pipe is arranged with a number of electricity generating turbines through a land mass.
  • the tidal water difference that exists between two ocean areas that are separated by a landmass is used for the production of electric energy in that a rotational body is made to be driven by a stream of water that is set up in a connection between the ocean areas, for the operation of an electricity generator.
  • a rotational body is made to be driven by a stream of water that is set up in a connection between the ocean areas, for the operation of an electricity generator.
  • geographical and topographical conditions lead to ocean areas with different tidal water patterns and thus different ocean levels lying close to each other as the crow flies, but are separated from each other by landmasses.
  • Such permanent changes in the vertical movement patterns of the water masses can be utilised for generation of power by a technically constructed horizontal connection through the landmass between the water masses.
  • FIG 1A shows a first embodiment of the present invention where a permanent time displacement exists in the tidal water cycles between two ocean areas and which one wishes to utilise according to the invention and this tidal water cycle is illustrated in the Figures 3 and 4A-4B.
  • Figure 1B shows an outline of a fjord system where analogic tidal water differences that can be explored arise between two locations.
  • Figure 2 shows a second preferred embodiment of the invention where a permanently different tidal water pattern exists between two ocean areas, as a constant different amplitude exists, as is shown in the figures 5 and 6.
  • the figures 7 and 8 show a situation where the landmasses create both a permanent time displacement of the tidal water cycle and a permanent different tidal water amplitude.

  • FIG 1A shows two ocean areas A and B that are separated by a landmass which forms a natural barrier S.
  • Said landmass can also, for example, comprise a subsea extended rock ridge that extends upwards towards the ocean surface without breaking the surface and will normally form a time displacement in the tidal water difference.
  • the ocean level differences can be characterised by:
  • the landmasses S of the barrier and/or topography of the ocean bed lead to a permanent time displacement in the tidal cycle between the ocean areas A and B.
  • the ocean bed is incidentally shown by the reference K.
  • the landmass as mentioned above, also comprises a subsea rock ridge that extends up towards the ocean surface without breaking the surface - there will also be formed a time displacement of the tidal water cycle and, as a rule, also changes in the tidal pattern. With all such locations a natural tidal stream will appear. As an additional effect of the present invention, all natural tidal streams can also be used for the generation of electric energy.
  • the artificial tidal stream With the application of the invention at different locations the artificial tidal stream will, in reality, be a draining of the natural tidal stream. That is, the volume of water which flows through the artificial tidal stream drains the through-flow of the natural tidal stream with a corresponding volume of water.
