How Does the Windmill Work?\n\nWind Energy\nWind is an indirect source of solar energy. It is caused by the uneven heating of the earth by the sun and the resulting redistribution of air to equalize energy in the atmosphere moving air from areas of high pressure to areas of lower pressure. The energy of the wind is transferred to the windmill’s sails where it is harnessed to perform work.\n\nThe cap of the windmill is turned with the winch attached to the bottom of the tail pole until the sails face the direction of the wind. Depending on the wind speed, wind boards are installed on the leading edge of the sails and canvas sail-cloths are unfurled across the sail-frames. The Miller climbs the sail-frame using the sail-bars like rungs of a ladder attaching the canvas to the cleats on the whip. High winds require less open sail than low wind. The Miller determines the amount of sail surface required based on wind speed and partially furls (reefs) the sails as required. The sails catch the wind and turn the wind-shaft.\n\nThe wind-shaft which is connected to the brake-wheel can be stopped with the brake which consists of a band of friction blocks encircling the brake-wheel attached to the brake lever and controlled via a rope near the tail pole attached to the brake lever. The turning brake-wheel turns the wallower connected to the upright shaft on the fifth level. A wood wheel on the fourth level is used to adjust any irregular spinning of the upright shaft.\n\nThe upright shaft is connected to a large gear called the spur-wheel on the third level. Power to run many things in the windmill is drawn from this wheel. Two stone-nuts turned by the spur-wheel drive quant shafts in turn rotating the runner stones; the top stones of the grinding stone pairs. The lower stone of the grinder is the bedstone; it remains stationary. The spur-wheel also turns a third lantern gear (trundle) to drive power transfer belts, pulleys and shafts used to operate the grain elevators, sifters, grain separator, corn sheller and a vacuum system.\n\nHow is Grain Ground into Flour?\nGrain and flour move through the system using grain elevators and gravity. Grain is carried into the windmill and poured into first level hoppers. From there it is cleaned in the basement with the corn sheller and grain separator. Grain elevators carry cleaned grain to the third level hoppers which hold it until it is dropped into the second level grinders. Corn & oats are ground in the west grinder and dropped into a ceiling mounted sifter on the first level. Wheat & rye are ground in the east grinder. The flour drops into an elevator at the ceiling of the first level, is carried back up to a hopper on the third level and dropped into the sifter on the second level. The sifted flour is stored in hoppers suspended from the ceiling on the first level.\n\nInteresting Notes\nThe windmill contains two scales; a floor scale in the windmill and a wagon scale outside the north end of the windmill. The scale inside the windmill can weigh individual bags of grain. The scale outside is used for weighing loaded and unloaded wagons.

sometimes they are made using a type of distill process.  they boil rose petals (for instance) and then collect the steam

Steam turbines obviously require steam, and therefore you will need a boiler, a condenser, and a water treatment facility. This could be fairly costly, but the steam turbine is a faily simple device, that runs very quietly. \n\nThe Gas turbine is very noisy, and wastes a lot of heat energy, there is a risk of explosion if not run properly, but a boiler carries the same risk. It may still be more efficient than the Steam Turbine. It requires scheduled cleaning of its air filter and its compressor blades, and will definelty need to be shut down for maintenence more often than the steam turbine.

Energy that is due to steam moving electrons steam electric energy. It the most common way of generating elcticity and is used in coal, gas oil and nuclear power stations.

Water is heated by any fuel may be solid fuels like coal etc or liquid like oils etc or gas like petroleum gas ,natural gas etc. The steam produced is allowed to collect till high pressure builds up. \nThis high pressure steam can be used in variety of ways depending upon requirement. It can run turbines to produce electricity, or a steam engine (recall the most earliest locomotive railway engines), or just transfer heat to some other source. However generally this steam is used in more then one way in a particular process. \nThere is a huge variety of ways to use this steam even to the extent of using some of it to preheat the water to again change it into steam. All the processes are well researched into and most of the processes are governed by the property of steam which has been tabulated in the steam tables which can be obtained from any engineering book store.\nThe subject dealing in detail on boilers is thermodynamics, a part of mechanical engineering.

Here are a couple of web sites that approach this in different ways. \n\nhttp://www.circletrack.com/techarticles/84199/\n\nhttp://www.diracdelta.co.uk/science/source/e/n/engine%20excitation%20mechanisms/source.html\n\nHope these help.

They burn the coal.\nThe heat generated by burning the coal is used to boil water.\nThe water turns to steam.\nThe steam turns a turbine.\nThe turbine is connected to a magneto.\nThe magneto generates electricity.\n\nViola!

For all steam and gas turbine... you need a circuit breaker. But it is only the matter of designing before or after the transformer and how safe you want to the system to be

All power plants convert heat into electricity using steam. At nuclear power plants, the heat to make the steam is created when atoms split apart.

steam has more energy in it. steam is derived from heating water up, so steam will contains much more energy and thus translate to a more powerful turbine .

Okay.  Well, usually it's like this:\n\n1. The first energy transfer depends on the kind of power plant, but the principle is a Fuel->Heat/Kinetic energy transfer.  In a nuclear power plant, the first transfer is Nuclear->Heat, in a coal plant, Chemical->Heat, etc.\n\n2. This heat from the initial reaction is used to boil water.  The energy remains in the form of Heat/Kinetic energy, but is simply transferred to the water.\n\n3. The steam turns a turbine.  Still kinetic energy.\n\n4. The turbine creates an electric potential.  Kinetic->Electric transfer.\n\nTo sum up: fuel reacts, boils water, steam turns turbine, turbine makes electricity.  Chemical/Nuclear/what-have-you -> Heat/Kinetic(in the water) -> Kinetic(the turning turbine) -> Electric

Steam (otherwise known as water in the gas phase) is produced when water boils.\nBut you already knew this.\n\nAll you need to do is boil some water.\nSet a pot on the stove, fill with water, turn on the heat, wait, and there is your "Steam Machine".

The short answer is that heat rises & cold air falls. As the sun heats the earth & THE EARTH ROTATES, warm air rises & falls as the day passes, creating movement of the air, combined with the evaporation of our seas into steam, the steam rises, just as heat rises, when the steam or heat reaches an elevation that makes the steam cool to a point that it can no longer rise, the steam becomes rain as the water particals bump into each other, eventually becoming too heavy, & they fall again.

In practice, a steam engine exhausting the steam to atmosphere will have an efficiency (including the boiler) of 5%, but with the addition of a condenser the efficiency is greatly improved to 25% or better. A power station with exhaust reheat, etc. will achieve 30% efficiency. Combined cycle in which the burning material is first used to drive a gas turbine can produce 60% efficiency. It is also possible to capture the waste heat using cogeneration in which the residual steam is used for heating. It is therefore possible to use about 90% of the energy produced by burning fuel—only 10% of the energy produced by the combustion of the fuel goes wasted into the atmosphere.

Solar Power harnesses the energy of the sun to turn water into high pressure steam. The sun gives panels which heat the water kinetic energy to affect the interaction energy of the water (like how you get a sunburn). The steam rotates a turbine to generate power.
