Ocean water pressure energy generation system

Abstract

A rigid cylinder structure is vertically positioned at sea bottom,so that the top of the cylinder's surface is at a depth of 300 meters below sea surface. This surface constitutes the upper face of a piston which moves within the cylinder,when it is exposed periodically by way of a shiftable opening & closing valve,which is located at the top of the cylinder,it intervenes,then exposes the piston at regular intervals to sea water pressure of 30 atm. Being basically a Pascal Hydrolic system,this pressure is transmitted through a pipe to a larger area piston,but in addition to the Pascal system, the multiplied pressure is in turn is used to pressurize a gas above it & compresses it to {fraction (1/9)} of it's initial volume. The result of compression is a 14 fold temperature increase-adiabatic. The high pressure & high temnperature as is then contained in a closed cycle second upper volume,which has just the exact dimensions for the gas which is compressed to {fraction (1/9)} of its initial volume. Here,the temperature & pressure is maintained constant as a result of a special valve & repeated compressions which supply additional pressure,which at each compression peak,lets pressure input in,but does not let a pressure loss when large piston makes its downward,hence decompression motion. Also within this volume is the spiraling pipe which attains thermal equilibrium within this space which contains the working gas. And the working gas,which has no condensation throughout the repeated cycles turns the turbines. Having no condensation & on the contrary being very strongly insulated,system eliminates the loss of internal energy. The minor loss of internal energy is more than compensated with each compression. Compressing a gas repeatedly every 40 minutes,to a fraction of it's initial volume & thereby to increase the temperature of the gas without any burning process & hence without any exhaust-greenhouse gas emission problems & without the need for very complicated & expensive equipment, system utilizes a natural and abundantly available,non-variable Renewable source;the Sea Water Pressure as the input force to the system. Which is converted repeatedly to a multiplied mechanic force to obtain pressure. These main features are what the system-invention presents as what is new in the art.

I claim: The system wherein the improvement comprises of utilizing the continous & Renewable-Costless natural Sea Water Pressure at certain depth to compress a gas to increase it's pressure, it has following methods and technical properties to derive following results from this objective:  
     
         1 . A method in which a gas could be compressed repeatedly to {fraction (1/9)} of it's initial volume within an enclosed space,as a result of mechanic piston,turning water pressure to mechanic-kinetic,in a Pascal hydrolic system. Input force exerted being the sea water pressure turned into mechanic motions of piston. Repeated every 30 to 45 minutes;has to be correlated to cycle completion time. 
 System is based on the following laws of physics: a. The non-compressibility of fluids.same with the Pascal Hydrolic,but in addition to Pascal,invention utilizes, b. The compressibility of gases of low density,high compressibility. Utilizing the continously vailable sea water pressure at 300 meters depth,as regularly repeated input pressure,the system would compress a closed cycle gas. This gas would reach thermal equilibrium with working gas.    
     
     
         2 . Since,a. The planet is covered 71% with water & b. Because system does not need an external sea water thermal gradient input,as in OTEC,& also c. Production of system would not require heavy investment,return on investment could be attained in a short time. System structure is such that,it can achieve economies of scale in production & be efficient at operation, because system can be applicable world wide,(planet is covered 71% with seas.) d. Furthermore,how the design is,can account for 80% of production costs.  
     
     
         3 . The method of  claim 1 ,including the step of introducing said moving pressure to the hydrolic press means to multiply the initial force applied. Said system is to multiply the input pressure of 30 atm/square inch at the small area piston,to at least 60 atm/square inch pressure,to be effective on the large area piston,which would compress the gas above it,to {fraction (1/9)} of it's initial volume.  
     
     
         4 . The method of  claim 3 ,which would include closed cycle low density,highly compressible gas, to be compressed to said fraction of it's initial volume,& obtained pressure is then placed into a pressure chamber.with a circulation loop for pressure control. Upper compression chamber ( 16   b ) is designed to keep said fraction of gas at high pressure & to serve the purpose to increase & keep a temperature of 650 C average. Because this limited time adiabatic temperature increase is of mechanic origin that can be repeated frequently,the lower compression volume would continuously provide pressure (similar to an air pump),input into the upper compression chamber,compensating the small energy loss/cycle.by at least 100%. Keeping Isochoric condition in upper volume  16   b.  Gas within the closed cycle pipes  20 ,would attain thermal equilibrium with pressurized gas in volume  16   b. Because a gas with large specific heat capacity would be used.the decline in temperature,when thermal equilibrium is reached. ( 700 C,)would only be about 25 C. Providing a superheated working gas of about 675 C.with about 270 atm working gas. Final energy conversion is mechanic to electric.  
     
     
         5 . The method of  claim 4 ,in which said gas would reach a maximum pressure.this said chamber would include at least one special one way high pressure resistant valve for directing pressurized gas from compression volume  16   a  into  16   b. but not vice versa located between volumes  16   a.   16   b.    
     
     
         6 . The method of  claim 5 ,which would include a set of pressure detectors & regulators.  
     
     
         7 . The method of  claim 1  which would involve a sequential order,that is,at that time when the valve below the compression chamber would close.large area piston would move back to it's initial position,to get ready for the next thrust-compression and also consequently,to avoid the compressed gas within compression chamber ( 16   b, ) to expand back to it's initial volume of pre-compression. As a result.at the other side,small area input piston would move back up.  
     
     
         8 . The method of  claim 3 ,in which compressions would be repeated periodically. Along with valve separation during piston downward motions & by good insulation.gas in  16   b  would be maintained at an optimal high temperature within a range of 550 to 650 Celsius. Which is to reach thermal equilibrium with a closed cycle working gas,to increase the pressure of the same to 270-300 atm. Internal energy loss of system is avoided as system has no condensation process.  
     
     
         9 . The method of  claim 8 ,in which temperature average of 650 Celsius would be achieved.to keep only the upper volume at Isochoric condition.( 16   b. ) The condition within compression space  16   a, would be adiabatic/cycle,but which can be repeated frequently to supply  16   b.  (Every 45 mins.)  
     
     
         10 . The method of  claim 9 ,which as a result of thermal equilibrium at 675 C,is to obtain a working gas at about 270 atm pressure,for turbines that are to be compatible to said pressure.  
     
     
         11 . The method of  claim 7 ,in which said system of water discharge.re-positions the small area piston repeatedly. (Sea water pressure input side & same side of sea water discharge.)  
     
     
         12 . The method of  claim 1 ,and because entire system structure is such that: a) No burning of fossil fuel is involved or no explosive burning occurs in the process.b) No heat pollution occurs, c) No chemical pollution into the sea occurs,system fullfills a high quality environment protection objective,as a System of Renewable Energy.  
     
     
         13 . The method of  claim 1 , where the Pascal based system is within water & also utilizes water pressure as input force.system is not subject to Gravity constraints since Pascal hydrolic is not subject to Torricelli's theorem of speed of efflux,as the hydrolic oil is in an enclosed system. Furthermore,since the discharge water quantity at the pressure input side is a small quantity & relative pressure conditions between sea surface & discharge volume is favorable to move said quantity with minor pumping,water to be discharged periodically would also not be a Gravity constraint. Furthermore,the thermal equilibrium & working gases do not constitute a Gravity problem.due to low density.
