  India Discovers Lithium in Karnataka ! Can we relate Mineral oil with lithium? India has initiated a concerted domestic exploration push for the alkali metal. A vital ingredient of lithium-ion rechargeable batteries that power electric vehicles, laptops, and mobile phones. Preliminary surveys by the  Atomic Minerals Directorate for Exploration and Research (AMD) , an arm of the Department of Atomic Energy, are learned to have shown- “The presence of 1600 tonnes of lithium resources in the igneous rock of the Marlagalla-Allapatna region of Karnataka’s Mandya District”. AMD is carrying out surface and subsurface Exploration for lithium in potential geological domains of the country . The find in Mandya is extremely small in quantitative terms, But it marks some initial success in the attempts to domestically mine the silver-white metal by way of hard-rock extraction of the ore. Imports India currently imports all its lithium needs. Its importance of lithium batteries tripled t...

  Turbocharger The first turbocharger was invented in the early twentieth century by the Swiss engineer Alfred Buchi who introduced a prototype to increase the power of a diesel engine. Turbocharging has now become standard for most diesel engines and is also used in many gasoline engines. Definition A turbocharger, colloquially known as a turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber. Construction A turbocharger consists of a compressor wheel and exhaust gas turbine wheel coupled together by a solid shaft and that is used to boost the intake air pressure of an internal combustion engine. The exhaust gas turbine extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction. Pros : Significant increase in horsepower. Power vs size: allows for smaller engine displacements to produce much more...
