The invention describes a better technique for plasma and energy generation with minimum amount of residue and pollution. The new apparatus uses very low cost method for plasma generation to convert any organic material into energy. This apparatus produces small amount of residue and pollution.
More particularly, the present invention relates to a process that uses solar or geothermal energy to remove the moisture from any organic material. The dried organic item is subjected to microwave to generate more energy with minimum gaseous pollution and solid residue. This new method reduces the cost of energy conversion and provides new method for energy conversion.
BACKGROUND OF THE INVENTION: World-over, the most common source of energy is fossil fuel like coal, oil, or gas, which are basically hydrocarbon fuels. The supply of these fuels is limited and they generate unwanted exhaust gases which are harmful to health and create pollution. Fossil fuels are not available everywhere. The fossil fuel such as petroleum, coal and gas contains complex compounds of sulphur and other chemicals, which results in unhealthy emissions.
Natural energy resources like wind energy, solar, geo-thermal etc. has been harnessed to some extent, but they can not be stored. However, it is not convenient to convert these energy sources into other forms of useful energy.
There is a need to devise a cost-effective method for converting and/or generating a useful form or forms of energy from organic material with minimum residue and pollution. 25 Present technology to convert an organic item into another directly useful form of energy needs further improvement to reduce the cost of conversion. 2 G:\Rajeev\400109NZ_AmendedCS_131005.doc INTELLECTUAL PROPERTY OFFICE OF N.Z 1 7 OCT 2005 rece ived In just about every industrial application, waste heat is constantly generated and released into the ambient environment. The amount of this waste energy is huge. The exhaust waste heat is considered as relatively low in temperature and it is difficult to recover this heat for any practical purpose. Significantly, there is no technology available to use this heat for 5 any economical advantage.
Thus, it appears that the prior art processes are deficient in that they mostly use nonrenewable fuel. They do not provide a suitable means of using the organic material or waste heat from industrial activities to generate more energy. 0 10 OBJECT OF THE INVENTION It is an object of the present invention to provide a method and/or apparatus for the cost-effective conversion of any organic materials into a usable form of energy by means of microwaves. The inventive apparatus utilizes solar and geo-thermal energy to reduce the cost of apparatus. The new technique further reduces the pollution, reduces the percentage 15 of solid-residue and reduces the cost of the apparatus. On exposure to microwave, the organic item is converted into plasma with the release of excessive light, heat and pressure.
Special feature within the apparatus reduces the over-all cost of plasma generation and reduces the amount of emissions. It is a significant improvement over known processes. Energy extraction from the plasma is achieved by using a new apparatus of solar-cells around the microwave cavity for the direct conversion of light energy into electrical energy.
DEFINITIONS Plasma may be defined as the fourth state of matter wherein matter is found in an energised, excited and/or ionised form.
Efficiency of plasma generation is measured by the amount of microwave energy required to convert a given amount of an organic material into energised plasma. 3 G:\Rajeev\400109NZ_AmendedCS_131005.doc INTELLECTUAL PROPERTY OFFICE OF NX 1 7 OCT 2005 received Organic Material as applicable to this invention relates to any organic material other than purely hydrocarbons and includes organic matter which is essentially derived from living, biological or waste organic matter.

DISCLOSURE OF THE INVENTION The invention provides an energy conversion system, which is capable of converting an organic item into a useful form of energy. The process uses renewable energy sources like solar energy and geo-thermal energy for converting organic item into a new kind of fuel. This fuel is exposed to microwave using a special device made-up of copper or tungsten, for efficient generation of plasma. The pollution from this energy conversion system is comparatively less harmful and solid residue is almost negligible.
Solar and geo-thermal energy are low temperature energy sources and direct energy conversion is uneconomical. However, the temperature of about 70degC to 1 lOdegC is sufficient to remove the moisture content of most of the organic items. Hence they can be used for the drying of organic items.
Plasma Generation: The main aspect of the invention provides for a method for converting organic material into plasma and usable form of energy by means of microwaves, the method comprising the following steps: (a) Use of solar-drying system or geo-thermal energy system to remove at least 80% to 90% of the moisture content of any organic material.

This plasma results into a chain reaction and the organic material converts into plasma with release of high intensity light and heat energy. At the same time, energy is released due to the creation of the atmosphere of highly energetic ions and electrons. Energy contained within the organic item or fuel is now converted into a usable form of energy selected from thermal, electrical, a high pressure, plasma, ionised air or gas and fusion energy. The exhaust contains negligible carbon soot with minimum gaseous and ash pollution.

Organic material now becomes a kind of fuel, which is renewable because it grows on trees and plants. It is very safe to handle, transport and store, without any danger of inadvertent ignition.
Microwave energy is used as an initiating energy source and the complete process becomes self-sustaining with the extraction of energy from plasma. Cost effective methods have been selected to achieve efficient energy extraction.
Extraction of Energy from Plasma: An additional aspect of the invention provides for the apparatus, wherein plasma generated at step (c) is confined within the glass chamber or heat exchanger used at step (b). The method to extract energy from the generated plasma comprises of: Installation of solar-cells around the glass vessel for direct conversion of the intense glow and light energy of plasma into electricity, Using the heat energy of plasma for external combustion engine like Sterling Engine, wherein a cylinder is heated externally for conversion of heat into mechanical and electrical energy, Plasma Dynamic Conversion (PDC), special electrodes are placed within the confined plasma for direct conversion of the kinetic and chemical energy of plasma into electrical energy, 6 G:\Rajeev\400109NZ_AmendedCS_131005.doc 1) 2) 3) 4) Electro-Hydrodynamic Plasma Conversion, the kinetic energy of energetic ions and electrons within the plasma is harnessed to extract energy. This kinetic energy is available to be converted into a useful form of energy, The energy extracted from plasma is further converted into any other form of useful 5 applications like, heating, mechanical work and electrical operations.
