    en.wikipedia.org/wiki/Spark_plug

    Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...

    A deployment of Bloom Energy Servers outside eBay headquarters. The Bloom Energy Server or Bloom Box is a solid oxide fuel cell (SOFC) power generator made by Bloom Energy, of Sunnyvale, California, that takes a variety of input fuels, including liquid or gaseous hydrocarbons [1] produced from biological sources, to produce electricity at or near the site where it will be used.

    Advantages of this class of fuel cells include high combined heat and power efficiency, long-term stability, fuel flexibility, low emissions, and relatively low cost. The largest disadvantage is the high operating temperature which results in longer start-up times and mechanical and chemical compatibility issues.

    Another method would use iron and sulphur instead of platinum. This would lower the cost of a fuel cell (as the platinum in a regular fuel cell costs around US$1,500, and the same amount of iron costs only around US$1.50). The concept was being developed by a coalition of the John Innes Centre and the University of Milan-Bicocca. [209]

    A commercially working cell in Japan called Eni-Farm is supported by the regional government, using natural gas to power up the fuel cell that then produces electricity and heated water. In 2013, 64% of global sales of the micro-combined heat and power fuel cell passed the conventional mechanical rotary systems in sales in 2012. [8]

    The PureCell System is a stationary phosphoric acid fuel cell designed, manufactured and marketed by Doosan Fuel Cell America (formerly ClearEdge Power/UTC Power) of South Windsor, Connecticut. Designed for distributed generation and micro combined heat and power applications, it is intended for industrial buildings such as hotels, hospitals ...

  8. Wasted spark system - Wikipedia

    en.wikipedia.org/wiki/Wasted_spark_system

    A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines. In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus ...

    Around 300,000 refrigerator trucks with auxiliary power units are on the road in the United States, according to a 2013 estimate. [3] In recent years, truck and fuel cell manufacturers have teamed up to create, test and demonstrate a fuel cell APU that eliminates nearly all emissions [4] and uses diesel fuel more efficiently.
