ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects‚ for example a galvanized nail and a copper coin‚ into an ion bridge (for example a lemon‚ a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes‚ causing anelectrochemical

ABSTRACT Currently‚ Philippines experiences economic crisis which results to higher costs of rare fossil fuels and LPG tanks which is used as a medium of cooking stoves. The study was conducted to construct a Rechargeable Charcoal/Wood-Feed Stove; a time-saver and a cost efficient appliance. It aims to compare the efficiency of the said stove to other commonly types of stove such as LPG Stove and Charcoal/Wood Clay Stove regarding with the time consumed when boiling‚ the watts consumed and the
