Engine. An engine is a mechanical device which is design to convert one form of energy into mechanical energy. Example. ·         Heat engine is use to convert heat energy into mechanical energy. ·         Electric meter is use to convert electrical energy into mechanical energy. ·         Hydraulic meter is used to convert pressure fluid into some mechanical work. ·         Molecular motor found in living things use chemical reaction to do useful work. Part of engine. Engine is used to produce some power, there are many part of an engine bolted together, they are used to do some work in connection with each other. Cylinder block or cylinder. Cylinder block is main part of an engine in which combustion (burning of fuel) take place many other parts such as piston, connecting rods, crankshafts are bolted in it. Piston. Piston is connected with cylinder block. It move freely up and down. It compress air fuel mixture and convert fuel energy into mechanical e

Alternative Energy Resources Alternative Energy. Alternative Energy can be define as “the energy which is not gain from the use of the fossil fuel, and does not increase humanity’s carbon footprint by the carbon dioxide emissions.” Alternative Energy Resources. Human civilization has started realizing how much harm they have already caused to the environment; and when it comes to take a stand against these environmental problems, the focus shifts to the use of alternative energy sources. Alternative energy encompasses all those things that do not consume fossil fuel. They are widely available and environment friendly. They cause little or almost no pollution.  Types of Alternative Energy There are several types of alternative energy resources from which most commonly known are written below, Solar. Wind. Ocean tidal. Geothermal. Nuclear. Solar. Solar energy is one the alternative energy source that is used most widely across the globe. About 70% of th
