FIELD OF INVENTION
[0001] The present invention relates to the fields of tidal and wind generation of electrical
power.
[0002] In one form the invention relates to a means of harnessing tidal motion in such a way
as to drive wind turbine/s for generation of electrical power.
[0003] In another particular aspect the present invention enables the adaptation of power so
generated to perform electrolytic production of hydrogen and oxygen from seawater.
[0004] In another particular aspect the present invention enables the production of food from
non-saline water derived as a byproduct of the operation of the invention.
[0005] In another particular aspect of the present invention deuterium and tritium derived from
hydrogen of the invention may be employed in the cold fusion process for energy production.
BACKGROUND ART
[0006] Tidal motion is attractive as a source of power generation by virtue of it’s relative
constancy throughout the world and presents obvious advantages as a sustainable power source
for the future.
[0007] Methods of harnessing tidal power which are currently in use involve:

Turbine applications responsive to tide-induced water motion through a restriction ie. dam wall,
natural constriction of coastline.
Positioning of turbines on the ocean floor in regions of strong tidal flow.
SUMMARY OF INVENTION
0008] Technical Problem: both methods expose the relevant machinery to highly corrosive
marine environments which render necessary increasingly expensive maintenance with the
passage of time. Both constitute a potential threat to shipping, one which is greatly increased in
violent weather conditions. Both constitute a hazard to marine fauna.
[0009] Solution to problem: the following invention avoids all the above by employing current
pipeline technology to connect ocean water to a large capacity cavity beneath the land surface
adjacent to the coastline. The cavity is filled and evacuated twice in each 25 hour tide cycle,
creating powerful air motion to drive an air turbine for electrical generation.
[0010] Advantageous effects: Such an arrangement places all relevant machinery on land, free
of corrosive action and convenient for servicing.
[0011] A turbine/generator of the Kaplan design is preferable to maximize drive from the
airflow at flood – from cavity - and ebb from tower - respectively using a system of piping and
shutters to direct airflow with each tide reversal
[0012] Kaplan design turbines perform most efficiently at low air speeds so are preferred for
the function of this invention.
[0013] The airspeeds produced by this invention do not subject the turbines to damage
consequent on overspeeding.
[0014] The installation is environmentally desirable on aural and visual grounds because it’s
bulk is below surface of both land and sea and turbine noise is channeled upward through the
condenser tower.

[0015] Air speed through the turbines is sinusoidal in response to tidal motion but in contrast
to conventional wind turbine technology generation continues throughout the diurnal cycle.
[0016] Air expelled during the flood phase of operation undergoes adiabatic condensation
following pressure drop on leaving the turbine and the water so produced is non-saline and
collected from the interior surface of the condenser tower for storage at ground level.
[0016] The invention generates electricity and enables embodiments which offer numerous
practical and economic advantages for present and future development.

DESCRIPTION OF EMBODIMENTS
[0018] The invention consists of a cavity constructed beneath the land surface adjacent to and
inland a convenient distance from the coastline, the upper altitude of the cavity being above the
highest peak tide level and lower altitude at the lowest tide level. The dimensions, alignment and
volume of the cavity bear a functional relationship to the tidal range such that it is filled with
seawater from each flood tide and emptied at each ebb. Where the tidal range is greater than ten
metres a vertical cylindrical cavity may be preferred, however many sites having lesser tidal
range may be utilized by constructing the cavity in the form of a large diameter tunnel extending
inland. A preferred format for this latter arrangement may consist of either a single unit or
network. A preferred diameter for the cavities will be 2 – 3.5 metres and these cavities will be
lined to prevent ingress of seawater to the surrounding ground.
[0019] The object of the cavity is to act as a tide-induced lung capable of absorbing from and
expelling to the atmosphere, the maximum volume of air with each tidal cycle.
[0021] A delivery pipeline connecting the lowest point of the cavity structure/s with an
offshore inlet. The preferred diameter of such pipeline being 1-1.5 metres so as to expedite full
function of the cavity assembly.[0022] An Inlet equipped with provision for screening against
large marine life and ocean floor debris is situated offshore at such depth beneath the ocean
surface as to present no threat to marine traffic. The design of this inlet features one or more
sloping screens which allow entry of water while diverting sea life from the screen. An
important consideration with the inlet is that it is located at such depth as to preclude entry of
matter under storm wave action.

[0023] An air turbine/generator situated at ground level above the highest point of the cavity,
with reverse routing of airways to enable operation of the generator on both tidal advance and
retreat.
[0024] A condenser. The air passed through the turbine at each flood exhaust has high
moisture content derived from the cavity, and on exit from the turbine is subject to adiabatic
release in it’s passage through the condenser tower. The interior surface of the condenser tower
incorporates spiral fluting throughout it’s height, the purpose of which is to increase the surface
area for more complete condensation, and channel the condensate to storage at ground level.
The condensate so obtained is non-saline.
[0025] Industrial Applicability: condensate water from the storage may be used for food
production under controlled greenhouse conditions which enable moisture recycling to maximize
production.
[0026] An electrolizer which uses electricity generated to produce hydrogen and oxygen from
the seawater provided that the hypersaline water exiting the process may be readily dispersed in
open ocean.
[0027] Gas storage, hydrogen and oxygen, for shipping to port storage facilities.
[0028] Hydrogen derived from seawater contains one part in 5000 deuterium. Monoatomic
hydrogen may be catalyzed by lithium to produce tritium. This invention provides the raw
materials and site for future energy production by deuterium-tritium fusion.
