3. Preamble to the description:

Complete Specification:

Summary:

In the summary of invention, each important salient feature is explained as follows:

1. Piezoelectric substances made up of nano quartz materials, lead titanium zirconate etc. Are arranged in array to construct device called piezoelectric accumulator as per inventors previous indian patent application number 2789/che/2010 dated 24/09/2010, c.b.r no 8434.

2. The electicitty generated from the waves of ocean hitting the above piezo electric accumulated connected, piezo electric panels is used as low cost power geneartion source.

3. The electricity generated in the above systems is used to provide cryogenic temperature surface alumina panels placed on the shore of ocean while connected to thermo electric chips made up of bismuth and antimony materials. As per the indian patent filed 2800/che/2010 dated 24/09/2010, C.B.R number 8438.

4. The subzero temperature surfaces placed like solar panels which can collect thermally condensed water vapours are arranged on the shore of ocean or any other humid atmosphere which are having sufficient rh percenatges.

5. The panels will have water accumulated systems on the bottom of slanted surfaces.

6. The above system can provide water not only from sea water, but from any wherever relative humidity is adequate enough to harness water from the water vapour surrounded.

4. Description

In this proposed method sea water is used as resource to produce desalinated potable water to meet ever increasing water needs. There are some kind of semi conductor chips which can achieve sub zero temperatures when little amount of electricity is supplied. This electricity is also produced by laying piezo electric accumulators on the seashore on stable surfaces. As sea waves continuously hits the piezo electric surface, they act as abundant environment friendly power resources to produce desalinated water also abundantly.

Background of invention

Desalination refer to any of several processes that remove some amount of salt and other minerals from saline water. More generally, desalination may also refer to the removal of salts and minerals, as in soil desalination, which also happens to be a major issue for agricultural production.

Salt water is desalinated to produce fresh water suitable for human consumption orirrigation. One potential byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources.

Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available and rapid overdraw and depletion of reserves is a critical problem worldwide.

6. Brief description of drawing:

• The vaccume chamber coated with salinity resistant polymer is half filled with salt water

• When the vacuum is created, the surface pressure on the salt water decreases drastically resulting in fall in the boiling temperature below atmospheric temperature.

• The water starts boiling the water vapour moves into condensation chamber coated with alumina dopped with ZR02

• Where there are peltiers which decrease temperature causing vapours to condensate

7. Claims

1. It is used to produce drinking water from sea.

2. It is used for industrial utility water requirements , irrigation requirments and other utility requirements.

3. This technique can also be used wherever rh % is more as a water maker machine from atmosphere.

4. Can Be used for recycling of affluent, sewerage and other type of disposed water where power cost can be controlled with some other means of power generation.

5. This System can be used for solvent recovery in industries.
