CLAIM OF PRIORITY 
       [0001]    This application does not claim priority to any patent or patent application. 
       FIELD OF THE EMBODIMENTS 
       [0002]    The invention and its embodiments relate to a system and method for preserving food by exposing the food to ozone. 
       BACKGROUND OF THE EMBODIMENTS 
       [0003]    Almost 90 percent of the global population consumes food products derived from agriculture. Improving the productivity profitability and sustainability of small holder farming is the main pathway out of poverty and the impetus for the innovation and invention described in the present application. The consequences of food waste that is food that spoils before it gets to market or on its way to the marketplace for consumers to purchase has ecological, economics and humanitarian implications. Crops, such as fruits and vegetables that spoil prior to consumption wastes water, leads to soil erosion and useless deforestation. Food waste means that monies spent on hiring workers to harvest, on fertilizers and on-pesticides is also wasted. In addition the social problems caused by food waste ultimately leads to hunger which can lead to whole regions and continents being malnourished and cognitive impairment which in many cases leads to social unrest. The need to keep crops and already produces food fresh for human consumption, post-harvest is the problem this invention solves. 
         [0004]    The average smallholder farmer face large losses of food due to spoilage at stage getting numbers. The FAO states that almost 45 percent of fruits and vegetables in developing countries never reach the consumers market tables or mouths. The smallholder farmer and their direct reseller, the market vendor lack the adequate protection for their produce from the harsh climate pests and diseases present in high moisture or humid climates. The present invention, marketed as a Wakati device solves the issue facing these farmers and vendors. 
         [0005]    The invention comprises wireless climate chamber device for storing fruits and vegetables such that any vegetables or fruits inside the device when stored at an optimal temperature and amount of time stay fresh longer thereby increasing profitability and portability in the supply chain. The invention may be used on the crop field, via transport from field to market vendor, via transport from market vendors to consumer home or even by the consumer at their home. Each step of the supply chain is assisted and each benefits from the problems the invention solves. The present invention, providers a chamber where the climate in which fruit and vegetables are stored is altered in order to increase shelf life and reduce post-harvest loss. The device requires a fraction of the energy and materials necessary for traditional cooling systems such as the portable refrigerator and freezer and as found in the prior art. 
         [0006]    For example the present invention is a marked improvement over the use of evaporation coolers. Such coolers use 350 to 700 liters of water for 100 kg of crops while the present invention uses 2 liters for 100 kg of crops. Such large amounts of water are unobtainable in large regions of Africa where water is scarce.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0052]    The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. 
         [0053]    Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto. 
         [0054]    The device creates a closed environment that is sterile and by adding an anti-fungal product the fruits and vegetables protect the crops from water loss, bruises and fungi. The device only uses two liters of water a week and is self-sufficient by utilizing a 3 watt solar panel. In another embodiment the device may be larger or small, use more or less water and be powered by a larger or smaller wattage solar panel depending on the needs of the farmer, market vendor or consumer. 
         [0055]    The unique cell structure of fruits and vegetable allows such crops to withstand high temperatures as long as they have a high turgor presage provided by the continuous flow of sap from the plant to keep the crop dehydrated. When a crop is harvested and removed from its root the link to their sap is lost and the dehydration clock begins to tick. A vegetable or fruit cell that is dehydrated ruptures easily and quickly causing vacuole fluid, an acid to form. This acid liquid contains enzymes which causes irreversible cell damage and decomposes the crop from the inside out. As such the dehydrated fruit or vegetable bruises easily. Bruising causes ethylene gas to be produced which attracts insects and fungi. If the fruit or vegetable is stored in an environment that mimics that can preserve the stability of their firm cell structure, the crops remain fresh and unbruised for a longer period of time. Buying time is what the present invention does. The present invention allows the crops cell structure to remain intact and prevents dehydration by creating a saturated humidity inside the device so that the crop doesn&#39;t lose water which is the primary effect of harvested dehydrated crop. The present invention not only protects the crops cells structure by creating high humidity but also destroys fungi and prevents further contamination of rotting crops by creating ozone. Ozone is created by a corona discharge, which is generated by multiplying the voltage from the solar panel so that no additional inputs it fungicides are needed. 
         [0056]    Ozone also for the elimination of ethylene production which is the ripening hormone of fruits and vegetables. Without ethylene and in the presence of high temperatures, crops do not bruise easily and rotting is slowed down. The ozone created by the present invention oxidizes ethylene into carbon dioxide and water, which prevents the rotting process. Any ozone produced by the present invention is below any dangerous level to human beings or animals. 
         [0057]    The present invention creates an environment where the hardness and weight loss of the crop is retained. Hardness is a good indicator for the transport suitability a crop may have while a crops weight loss is directly linked with how sellable a crop is. The less weight a particular vegetable or fruit undergoes or the more hard a fruit or vegetable is directly indicative to its freshness, ripeness and consumer consumptions. Depending on the particular fruit or vegetable, the present inventions allows for the weight loss of the fruit or vegetable to be dramatically decreased. 
         [0058]    The present invention operates by creating air ions. Air ions are short lived, lasting only minutes before they lose their charge. Their life-time is reduced by contacting walls or surfaces, or by interactions with pollutants or humidity in the air. Negative air ions (NAI) reduce airborne mold and bacterial contaminants. The growth of cultured bacteria is retarded and the viability of bacteria and fungal spores in aerosols is reduced by exposure to NAI in concentrations ranging from 5×10 4  to 5×10 6  ions/cm 3 . A combination of ozone (O 3 ) with NAI is reported to be more effective than either of them alone, in suppressing microbial growth and decay of fresh produce. When cultures of  Erwinia  caratovora were exposed to 10 6  NAI/cm 3  and/or 50 ppb O 3  at 10° C. for 6 hours, viability of O 3  treated bacteria was 70%, whereas viability of those treated with O 3  and NAI was only 4%. The synergistic effect of NAI with O 3  could explain the variable effectiveness of O 3  in reducing decay of stored produce. In two separate studies, the lesion growth rates of  Botrytis cinerea  and  Sclerotinia sclerotiorum  on fresh carrots was reduced by 12% and 16%, respectively, when held in 1 ppm O 3  without NAI. However, in a similar trial where carrots were held in 0.1-0.5 ppm O 3  in combination with 2×10 4  to 7×10 4  NAI/cm 3 , growth rates of  B. cinerea  and  S. sclerotiorum  were reduced by 69% and 57%, respectively. The apparent synergism of NAI with O 3  could provide an effective method to reduce postharvest decay of fresh produce. 
         [0059]    The present invention allows for the addition of various natural product such as essential oils or the odorless hydrogen peroxide to be added to the device in order to eliminate/reduce the amount of fungicides the crop may grow. In a preferred embodiment of the present invention 5 hours of sunlight a day is needed to provide the energy to run the device. The present invention is lightweight and weighs about 5 kg or roughly 11 pounds. The present invention is collapsible and requires minimal set up and installation. 
         [0060]    In a preferred embodiment, the present invention is capable of optimizing the properties of the inner chamber for various crops. This embodiment allows a user to adjust the humidity, ozone level, and ionization level of the present invention. These levels can be correlated to optimally store a particular crop or crops. In various embodiments, this functionality is achieved by a fan to control the humidity. Further, preferred embodiments will provide for the ozone generator to be at full power, half power, or simply be off. Additionally, other embodiments will have the ability to selectively turn off the ionization caused by the present invention. 
         [0061]    In another preferred embodiment, the present invention is capable of entering a sterilization mode where the ozone generator is left of full power for a predetermined period of time. This setting is intended to be used when the present invention is not filled with produce. Further, some embodiments of the present invention are capable of merely generating ionizing air, so that a walk-in embodiment of the present invention may be used. It should be noted that in various embodiments, the present invention may take a wide variety of sizes.
