A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Due to their broad range of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. P[..]
The most common Hydroelectric power plant uses an “Impoundment.” This is where a dam is built across a river which impounds the water behind it in a reservoir. This water is then released from the reservoir through a turbine, which spins and activates a generator which produces electricity
A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.

Diesel fuel /ˈdiːzəl/ in general is any liquid fuel used in diesel engines, whose fuel ignition takes place, without any spark, as a result of compression of the inlet air mixture and then injection of fuel. (Glow plugs, grid heaters and block heaters help achieve high temperatures for combustion during engine startup in cold weather.) Diesel engines have found broad use as a result of higher t[..]
