1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two
Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular! . In fact, the term "turbocharger" is a shortened version of "turbo-supercharger," its official name. The turbocharger is bolted to the exhaust manifold of the engine. The exhaust from the cylinders spins the turbine, which works like a gas turbine engine. The turbine is connected by a shaft to the compressor, which is located between the air filter and the intake manifold. The compressor pressurizes the air going into the pistons. The exhaust from the cylinders passes through the turbine blades, causing the turbine to spin. The more exhaust that goes through the blades, the faster they spin.On the other end of the shaft that the turbine is attached to, the compressor pumps air into the cylinders

concrete into a a higher basin. The tapering is used to enlarge the velocity of the water flow following the continuity equation. The kinetic energy of the wave is transferred into potential energy of stored water in the upper basin. This principle follows the hydrodynamic law of Bernoulli's equation. A Tapchan wave power plant uses a continuous flow of the seawater stored in the upper basin through a low pressure turbine driving a generator of conventional construction to generate electricity. Low head Kaplan turbines are used mostly to convert potential energy into electrical energy. The water storage (reservoir, basin) helps smoothing the electric output. With its integral storage system, a Tapchan is different to most of the other regenerative energy conversion technologies. The following equation governs the energy of water waves:

Another unit of radioactivity is the curie, Ci, which was originally defined as the activity of one gram of pure radium, isotope Ra-226. At present it is equal, by definition, to the activity of any radionuclide decaying with a disintegration rate of 3.7 × 1010 Bq. The use of Ci is presently discouraged by the SI. History of nuclear power The basic process of Nuclear Power is an exothermic chemical decomposition reaction that heats water to steam. This steam pushes the steam turbine that is connected to a generator that converts the mechanical energy of the turbine to electrical energy. For this reason, the history of the steam engine and the steam turbine will also be included on this timeline. Also see the comparison page for Combustion, and the general Comparisons page for more information on the underlying processes of many alternative energy forms. At 100 BC an Alexandrian (Greek speaking) philosopher by the name of Ctesibius invented the piston pump.
Fifth level Negative aspects of solar energy Solar energy does not work at night without a storage device such as a battery. Cloudy weather can make the technology unreliable during the day. Solar technologies are very expensive. Requires a lot of land area to collect the sun's energy. Wind energy Most wind energy comes from wind turbines. Wind turbines are used to wring electricity from the breeze. Wind turbine use has increased at more than 25 percent a year. Wind is a clean source of renewable energy that produces no air or water pollution. Wind is free, operational costs are nearly zero once a turbine is erected. Negative aspects of wind energy Wind turbines make noise. Slowly rotating blades can kill birds and bats. Wind is variable: if it's not blowing , there's no electricity generated. Wind turbines are expensive. Hydroelectric power
Two reactors were under construction at the time of the accident. An artificial lake was constructed to provide cooling water for the reactors. The 1986 Chernobyl accident On 25 April the reactor crew at Chernobyl 4 began preparing for a test to determine how long turbines would spin and supply power to the main circulating pumps following a loss of main electrical power supply. This test had been carried out at Chernobyl the previous year, but the power from the turbine ran down too rapidly, so new voltage regulator designs were to be tested. A series of operator actions, including the disabling of automatic shutdown mechanisms, preceded the attempted test early on 26 April. By the time that the operator moved to shut down the reactor, the reactor was in an extremely unstable condition. The interaction of very hot fuel with the cooling water led to rapid steam production and an increase in pressure
It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs. Street light use 5% of energy, but it can be reduced to 2%. Usual TVs should be replaced with Plasma TV, because it saves energy more. By driving electic-car, it is possible to save energy about 20% and reduce global emissions. Carbon dioxide is used to grow tomatoes. Tomatoes which are eaten, have come out straight of exhaust of engine and gas turbine burning gas. But still this carbon dioxide finds its way to atmosphere through our bodies. It is possible to save energy if you isolate your freezers what freezes fish. Then you can reduce your freexing temperature. Deserts would be amazing places to storage sunlight energy. But to do this, we have to forget AC, because we need DC lines. If many big countries would say, that roofs have to have solar cells, it saves a lot of energy and saves also money

In 2005, renewable energy represented one-fifth of total power generation. Hydropower is the most advanced of the renewable and represents 87% of this production. 160 countries all over the world are using hydropower. Five countries make up more than half of the world's hydropower production. Those countries are: Brazil,Canada, China, Russia and the USA. (Production) *Most of the energy comes from the potential energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. *Pumped storage hydroelectricity produces electricity to supply high peak demands by moving water between reservoirs at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the reservoir. And when there is a big demand, like in the evenings, then the water is

The estimated average cost per unit incorporates the cost of construction of the turbine and transmission facilities, borrowed funds, return to investors (including cost of risk), estimated annual production, and other components, averaged over the projected useful life of the equipment, which may be in excess of twenty years. Energy cost estimates are highly dependent on these assumptions so published cost figures can differ substantially. A British Wind Energy Association report gives an average generation cost of onshore wind power of around 3.2 cents per kilowatt hour (2005)
To safeguard the pump, a course filter (4) is inserted between the pump and the bottom tank. The pump forces the oil a through lubricating oil cooler (6) and filters (7) to the main engine (1) where the oil is distributed to bearings and pistons. TURBOCHARGE SYSTEM Most modern engines are turbocharged to increase the power output and efficiency. The efficiency of the system is increased by fitting a charge air cooler after the compressor. Exhaust gas from the cylinders operates the gas turbine, giving up some of its heat energy to do so. The turbine drives a directly coupled air compressor, which draws air from the atmosphere, compresses it and then cools in the charge air cooler before supplying it to the engine through scavenge ports. Turbocharger consists of a single stage, axial flow exhaust driven turbine mounted on a common shaft with a centrifugal air compressor. The turbine has a nozzle ring followed by a rotating disc with a single row of turbine blades. Blades and nozzles
