A PROCESS OF PREPARATION OF A VEGETATIVE VOLTAIC CELL

Abstract

According to this invention there is provided a vegetative voltalc cell. The vegetative voltaic cell of the present invention comprises of a slurry made up of the leaves of the plant as an electrolyte. The vegetative voltalc cell comprises of an insulated water proof container having plurality of chambers with electrolyte stored therein, a plurality of electrodes disposed in the said electrolytes, said electrodes being positioned in each chamber through a lid of the container. A plurality of such cells are connected either in series or in parallel and the final output terminal passes through the outer surface or the lid. The slurry of the leaves is produced by using the leaves of any plant. The mature fresh leaves are ground with distilled water to make a slurry of 500 ml. Juicy fresh plant leaves or leaves of succulent plants with proper preservatives such as borax, Na-benzoate etc. give better results. The slurry is then poured into the chamber. Different types of plants are used. Some of which differ in their metabolic patterns. Thus, Bryophyllum is a Crasulacean plant and its cell sap is acidic in nature due to dark fixation of CO2 at hight, whereas the other plants do not have this type of metabolism. Consequently, it is expected that many other plants can be used conveniently depending on their electrolyte contents. The observed current may be considered as a short circuit current. There is no direct impact of light for such power generation since the same power is obtained in darkness. Electrolytes, oxidants and reductants present in plant organs, which participate in the complex biochemical reactions are apparently involved in the generation of power.

This invention relates to a vegetative voltaic cell. BACKGROUND OF THE INVENTION A large and cheap source of energy is an essential requirement for the development of a growing nation. With the advancement of civilization the demand for energy sources has grown and the need for new sources of energy ecomes essential. At present, besides conventional energy sources, a constant quest for non-conventional energy has begun and researches in this area are in progress. Common voltaic cells use commercially available inorganic salts as electrolytes for power generation. Since all plant materials contain various types of inorganic and organic electrolytes absorbed through their root systems or synthesized through metabolic processes, it was the possibility of constructing a cheap vegetative voltaic cell was examined using commonly available plant materials. OBJECTS OF THE INVENTION An object of this invention is to propose a vegetative voltaic cell which is cost effective. Another object of this invention is to propose a vegetative voltaic cell which generates power from biological materials such as plant leaves. Further object of this invention is to propose a vegetative voltaic cell which is very simple and is free from environmental pollution. Still further object of the present invention is that the vegetative voltaic ceK can be re-used by Just changing the leaf slurry. DETAILED DESCRIPTION OF THE INVENTION According to this invention there is provided a vegetative voltaic cell. The vegetative voltaic cell of the present invention comprises of a slurry made up of the leaves of the plant as an electrolyte. The vegetative voltaic cell comprises of an insulated water proof container having plurality of chambers with electrolyte stored therein, a pluralty of electrodes disposed in the said electrolytes, said electrodes being positioned in each chamber through a lid of the container. A plurality of such cells are connected either In series or In parallel and the final output terminal passes through the outer surface of the lid. The slurry of the leaves is produced by using the leaves of any plant. The mature fresh leaves are ground with distilled water to make a slurry of 500 ml. Juicy fresh plant leaves or leaves of succulent plants with proper preservatives such as borax, Na-benzoate etc. give better results. The slurry Is then poured Into the chamber. Different types of plants are used. Some of which differ in their metabolic patterns. Thus, Bryophylum is a Crasulacean plant and Ns cell sap is acidic in nature due to dark fixation of CO2 at night, whereas the other plants do not have this type of metabolism. Consequently, it is expected that many other plants can be used conveniently depending on their electrolyte contents. The observed current may be considered as a short circuit current. There is no direct impact of light for such power generation since the same power is obtained in darkness. Electrolytes, oxidants and reductants present in plant organs, which participate in the complex biochemical reactions are apparently involved in the generation of power. DESCRIPTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS: Fig 1a & 1b: Shows an insulated water proof box which is covered with a lid. Fig 2: Shows the series and parallel connections of the chambers in the box Fig 3: Shows the vegetative voltaic cell consists of two different types of electrodes. The electrodes are properly arranged in the fid of the cell. The lid carries electrodes for each of the chambers in the box with series and parallel connections and final output terminal passes through the outer surface of the lid. The vegetative voltaic cell consists of two different types of electrodes of different elements and the two electrodes with its chamber form a unit. One of the electrodes acts as anode and the other as cathode. Several different types of electrodes can be used. On combining a number of units in series and parallel a battery of cells of moderate power can be formed at any desired value as shown in Table 1. As an examplary embodiment, the device shown in figure 2, has 12 chambers and the volume of each chamber is 50cm3. Carbon as cathode (7.5cm x 5.0 cm) and zinc as the anode (10.0 cm x 5.0 cm) gave good results. The carbon electrodes are placed at the center of each of the chamber on the lid and the zinc electrodes are fixed round the carbon electrodes leaving a space (0.5 cm) In between them. The power generated depends on the nature and condition of the leaves, size and nature of the electrodes and the type of combination of the units. A comparative account is given below. With the help of this, any low power-consuming circuit such as transistor radio, calculator, electronic wall clock, light-emitting diode etc. can be operated. The detail features of instant invention are as follows: (i) Unlike costly and complicated conventional cells using salt, acid or alkali, this device generates power from substances present in biological materials, especially from plant leaves. (ii) The device can generate power from leaves of any plant, including weeds. Any part of a plant such as the soft stem. root, fruit juice, leaf and algal material can be used for this purpose. (iii) The vegetative voltaic cell can be re-used by changing the leaf decocation. Again, by replacing any part of the device, it may further be repeatedly used. Here, the corrosive effect of the energy source is nominal, so the electrodes remain in good condition for a long duration. As the electrolytes are mostly weak organic ions, corrosion would be much less than in the case of strong electrolytes. One of the electrodes is carbon, which is not affected by corrosive action. (iv) The plant decocation was treated with Na-benzoate or borax to prevent microbial contamination. 1.
