“Household batteries” are the small portable batteries used daily by most people in devices such as radios‚ toys‚ flashlights and lanterns‚ games‚ watches‚ calculators‚ hearing aids‚ cameras‚ telephones and other communications devices‚ but do not include the larger batteries used in motor vehicles‚ commercial and industrial‚ military and other applications. They are called “dry cell batteries” because they contain no freestanding bodies or pools of liquid electrolyte. Household batteries are divided

Prior to this acquisition‚ the Duracell Corporation had been the leading producer of alkaline batteries in the United States and maintained consistent growth in revenues from 1991-1996. Since their purchase of Duracell‚ their stock price has fallen 45% to a low of $34. The issue for Gillette is to determine if they can promote the profitable growth

The Science of the Spud — a History of the Potato Battery Experiment There are hot potatoes‚ french fried potatoes‚ baked potatoes and scalloped potatoes. There are potato chips‚ potato pies and potato soufflés. Last‚ but not least‚ there’s the potato battery. Who on earth invented the electric spud? Why does it work? For that matter‚ why would anyone want to see if a potato could conduct electricity in the first place? Well‚ we may never be able to answer some of the questions this quirky experiment

has potential in the future‚ but did not deliver desired results. The idea was to make a vertical axis wind turbine (VAWT) that instead of charging a battery‚ would deliver its power directly to an electrolysis apparatus to make hydrogen and oxygen gas. The reason for doing this would be to avoid the complications and expenses of inverters‚ batteries‚ and connecting the turbine to the grid. It would also make hydrogen gas which could power a car‚ a generator‚ or be used as a welding/cutting torch

Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications of this DC to DC converter is stepping down the

technology. Ballard had a leading edge with their technology and product innovation as a result of years of research. It all started in 1970 when Geoffrey Ballard‚ Keith Prater and Paul Howard agreed to develop a rechargeable and lightweight lithium battery. Although the company’s main product line was the batters‚ the three partners had a vision to produce the rechargeable lithium type. To what extent should spin-off technologies be transformed into stand-alone products? Spin-off technologies should

Commercial Cells Galvanic Cell A Galvanic cell is also known as a Voltaic cell. It was named after Luigi Galvani and Alessandro Volta. A galvanic cell is capable of producing an electric current from a redox reaction that occurs within it and consists of two half cells. Each half cell consists of an electrode and electrolyte and a salt bridge. In a galvanic cell one metal can undergo reduction and the other oxidation. A typical galvanic cell is based on the spontaneous redox reaction: Net Ionic

Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known
