A New Rechargeable Electricity Storage Battery
The invention relates to a rechargeable DC storage battery that comprises lead oxide / lead dioxide as positive electrode, lead as negative electrode and a saturated ionic solution of sodium / potassium / lithium dichromate as electrolyte. Upon charging, the positive lead oxide is converted into lead dichromate and negative lead is converted into lead dichromate. Upon discharging, the positive lead dichromate is converted back into lead oxide whereas negative lead dichromate into lead. It has discharging efficiency with greater than 90% and faster charging with more than 2000 charge & discharge cycles. The invention has been applied for patent protection (Indian Patent application no. 0214DEL2012).

An electric battery containing tannery effluent as an electrolyte
The invention provides an electric battery prepared from chemically modified tannery effluent water with the addition of an inorganic salt. It comprises a combination of cells connected either in parallel or series. Each cell is composed of one positive electrode selected from carbon, lead; a negative electrode selected as Iron; and an electrolyte prepared from chemically modified tannery effluent water using an inorganic salt. The battery produces an open circuit voltage of 1.5V to 1.6V and 9.0V to 9.6V when six cells are connected in parallel and series, respectively. The unique feature of the invention is that it provides an option to utilize the polluting tannery effluent water in an economical way. Indian Patent application no. is 0941DEL2014.

A process for the generation of bio-electricity
Disclosed herein is a process for the production of electricity primarily from the biological sources of both plant and animal origin. It finds. enormous application in providing an eco-friendly solution for the economical disposal of the fleshing produced as solid waste during leather making processing. Further, the electricity generated finds potential application for the purpose of direct current (DC), alternating current (AC) and bio-batteries. Indian Patent application no. 201711017228.

A Device for capturing sea wave energy
Disclosed herein is a non-floating non-submersible sea wave energy converter device for capturing substantial amount of energy available in sea waves. A simple pendulum attached with two pillars is moved by the sea waves. Only the waves with visible amplitude can strike the pendulum which in turn swings in the same direction and the attached components convert this into mechanical energy. Repeated strike by the waves push the pendulum to swing with more or less rhythmic frequency. The pendulum is connected with a wire rope through a pulley or swing rods which in turn is connected with a generator or power take off. A series of the non-floating non-submersible sea wave energy converter devices ensure constant flow of mechanical energy for industrial applications. Further, a pillar can be shared by two successive devices, thereby reducing the capital. Indian Patent application no. 201711035700.
