Hydroelectric cell path breaking invention for green electricity production by splitting of water -An alternative to solar cell and fuel cell for masses

R K Kotnala

Revolutionary path breaking invention of the green energy device Hydroelectric Cell, HEC, is an alternative to Solar cell and Fuel Cell for Masses. HEC represents the most versatile green energy solution ever invented. It is an exceptional advancement in the development of green energy sources and it has opened a new frontier area of research. Hydroelectric cell dissociate water molecules into ions at room temperature without using any external energy to generate electricity, which is one of the best options as an eco-friendly and pollution free green energy device invention of 21st century. Sprinkling of a few drops of water on Hydroelectric Cell generates electricity spontaneously without use of any acid/alkali/light on it. Hydroelectric cell working principle is the combination of material science, nanoscience and electrochemistry. Nano porous oxygen deficient metal oxide material used in hydroelectric cell dissociates water molecules into hydronium and hydroxide ions at room temperature, hydroxide ions at Zn anode form nano zinc hydroxide and hydronium ions liberate hydrogen gas on the Ag inert cathode. Nanoparticles of zinc hydroxide and hydrogen gas by-products are formed at electrodes on the metal oxide pellet of the cell. The by-products of HEC are also very useful and non-toxic. Hydroelectric cell (HEC) technology offers safe, clean, low cost and reliable power generation to almost any electrical device. The Cell can be used in a wide range of portable, stationary and transport applications from battery chargers to low power devices. The utilization of Hydroelectric Cell for domestic electrical energy needs and as an automotive power source would be a key factor in terms of economy, safety and easy usage to replace hydrogen energy based fuel cell, storage batteries etc. Its usage would significantly reduce urban pollution. In all of these applications, there is a need for reduced system cost, high reliability and acceptable performance. While the performance of the prototype developed system has made remarkable strides, there is still much work to be done for its large-scale application and durability. HEC represents the most versatile green energy solution ever invented. Dr. R. K. Kotnala and Dr. Jyoti Shah have invented and developed a new electrical energy source using porous magnesium ferrite and metal oxide pellet based Hydroelectric Cell. A two inch diameter cell develops a maximum Voltage 0.95 V and a short circuit current of 120 mA. Results are highly comparable to solar cell and other portable electrical energy sources. Hydroelectric Cell even at prototype stage is proving superior over solar cell and fuel cell application in much better way.
