How can someone get windmill jobs to work on windmills?

The first step in getting a windmill job is to get trained by going through a wind tech training program. The fastest and most reputable ones are California Wind Tech and Danish Renewables. After receiving a certificate of completion from a windmill training program, you can get hired by a staffing company that provides operations and maintenance services to wind parks. Staffing companies tend not to pay a premium to their employees, but it is a sure way to get your feet wet in an industry that is rapidly growing and can pay very well ($80,000+ a year U.S. after one or two years of tech experience). These are the easiest and fastest ways to get a windmill job as they can be moderately difficult to get into for those who have no industry experience. Contracted employers in the wind industry typically do not have time to train new employees and frequently choose to hire those that have prior training or references from people the employer knows personally.

What energy transformations occur in a hairdryer?

Motor action occurs when electromagnetic energy (electricity) is converted into mechanical energy (rotation) by the fan motor. The fan then turns and air moves through the device. Electromagnetic energy (that same electricity) is also converted into thermal energy in the heating element, and from there the heat is transferred into the air as it passes by.

Why would power run to your computer's fan but nothing else?

If another power supply doesn't work, it's likely your motherboard has failed.

It could be that you need to buy a new processor. It may be "fried."

However, there may be other causes. It could be as simple as reseating drive cables, power connectors, etc. There is not enough information in the original question to determine what the problem is. (Which fan is on, the power supply or CPU fan or one of the case fans?)

A Power supply can be strong enough to get the fan going but not enough juice to power up the system!

That ia a weak Power supply that can power up a fan but not the system, try another power supply.

What are the basic principles of electricity?

Firstly, Electricity is the movement of electrons (Or positive "holes")Some basic principles of electricity:

-Opposite electrical charges always attract each other, and Like electrical charges always repel.

-An INSULATOR is any material that inhibits (stops) the flow of electrons (electricity). Insulator material includes glass, rubber, and plastic.

-A CONDUCTOR is any material that easily allows electrons (electricity) to flow.

Conductor material includes copper, silver and gold.

-Any material with exactly 4 free electrons in the outer orbit are called SEMICONDUCTORS.

A semiconductor is neither a conductor or insulator.

semiconductor material includes carbon, silicon, and germanium.

These materials are be used in the manufacturer of diodes, transistors, and integrated circuit chips.

-Electron Theory states that current flows from NEGATIVE to POSITIVE. Electrons move from atom to atom as they move through the conductor towards positive.

-Conventional theory, also known as HOLE THEORY, states that current flows from POSITIVE to NEGATIVE. Protons or the lack of electrons (the holes) move towards the negative. (Current flow direction in Hole Theory is the opposite of that in Electron Theory.)

-Voltage is the electrical force that moves electrons through a conductor. Voltage is electrical pressure also known as EMF (Electro Motive Force) that pushes electrons. The greater the difference in electrical potential push (difference between positive and negative), the greater the voltage force potential.

-A Voltmeter measures the amount of electrical pressure difference between two points being measured. Voltage can exist between two points without electron flow.

-Voltage is measured in units called VOLTS.

-CURRENT is the quantity or flow rate of electrons moving past a point. Current flow is also known as amperage, or amps for short.

-An AMMETER measures the quantity of current flow. Ammeters are placed in series (inline) to count the electrons passing through it.

-Current flow is measured in units called Amperes or AMPS.

-Two common effects of current flow are Heat Generation and Electromagnetism.

HEAT: When current flows, heat is generated. The higher the current flow the greater the heat generated. An example would be a light bulb. If enough current flows across the filament, it will glow white hot and illuminate to produce light.

ELECTROMAGNETISM: When current flows, a small magnetic field is created. The higher the current flow, the stronger the magnetic field. An example: Electromagnetism principles are used in alternators, ignition systems, and other electronic devices.

-Resistance is the force that reduces or stops the flow of electrons. It opposes voltage. Higher resistance will decrease the flow of electrons and lower resistance will allow more electrons to flow.

-Resistance is measured in units called OHMS.

-Two basic types of Electricity classifications:

STATIC ELECTRICITY is electricity that is standing still. Voltage potential with NO electron flow.

DYNAMIC ELECTRICITY is electricity that is in motion. Voltage potential WITH electron flow. Two types of Dynamic electricity exist:

Direct Current (DC) Electron Flow is in only one direction.

Alternating Current (AC) Electron flow alternates and flows in both directions (back and forth).

-Electricity can be created by several means: Friction, Heat, Light, Pressure, Chemical Action, or Magnetic Action.

In an automobile the battery produces electricity through chemical action, and the alternator produces electricity through magnetic action.

Friction creates static electricity.

Heat can act upon a device called a thermocouple to create DC.

Light applied to photoelectric materials will produce DC electricity.

Pressure applied to a piezoelectric material will produce DC electricity.

Chemical Action of certain chemicals will create electricity.

Other contributions:the principles of electricity gradually became understood. Thomas Edison helped change everyone's life -- he perfected his invention -- the electric light bulb. Prior to 1879, direct current (DC) electricity had been used in arc lights for outdoor lighting. In the late-1800s, Nikola Tesla pioneered the generation, transmission, and use of alternating current (AC) electricity, which can be transmitted over much greater distances than direct current. Tesla's inventions used electricity to bring indoor lighting to our homes and to power industrial machines.Answer 2Thomas Edison did NOT invent the electric light bulb. This was something that several inventors worked on for many years. Edison, through trial and error, found that tungsten worked good and lasted long as a filament, and was able to draw sufficient vacuum in the bulb to make it last a long time.

Again, Edison primary worked on the principle of trial and error. Nikola Tesla figured out what he wanted to do, thought about and designed what he thought would work. When he built it, it usually worked.

Thomas Edison & Nikola Tesla worked in labs a few miles apart in New York. While Edison was working on his electric lamp, Tesla was working on the AC distribution system we still use today, in his lab lighted by fluorescent lamps he designed and built.

How do windmills work?

The blades are twisted so they rotate when the wind blows. This rotation can be used to turn millstones to grind corn into flour, or to pump water out of the ground, or to turn a turbine to produce electricity.

The sails of a mill are set at an angle to the wind. As the wind spills off the sails it imparts some of its kinetic energy to the shaft and starts it turning. A tail fan is used to automatically point the mill into the wind. The rotating shaft has a gear wheel which supplies energy to the hursting frame, where the two millstones, one fixed and one rotating, are kept a small distance apart. Grain is fed into a hole in the center of the rotating stone and progressively moves to the edge whereupon flour falls into sacks via a chute.

Wind produces kinetic energy which moves the rotor and, when the rotor moves the gears also move and turn the generator. When the generator turns, it will change the kinetic energy turn to electrical energy.

A:A windmill works on the principle of wind energy. when the wind blows its force make the blades of the windmill to move. they move in circular motion . thus, the energy of wind can be made to electricity or to grind grains into flour. it is a much better way as it is Eco friendly.
Windmills have large blades or propellors which catch the wind. When the wind blows the blades turn. This turning motion can be used to grind corn, pump water or generate electricity.
Wind blows into the large fan, fan has a shaft through the centre that extends to the rear. Flange fitted to the rear of the shaft has a connection point like a stud or such. A long shaft is then attached to the connection (must be a flexible connection & shaft usually runs down vertically to well/bore), As the flange spins with the fan shaft, the attachment point prescribes a vertical circular motion, the shaft attached to the connection point will be raised up and down as the fan completes each circle. The shaft can then be attached to any other mechanical device that can use such energy.

What should you do if you get the wind knocked out of you?

Put your hands above your head and just breath

If you can, sit down but keep your back straight (this lets your lungs expand more). Also, if it's bad enough to a point you can't stand, lie down but DO NOT lie on your back. Your lungs have to work twice as hard then and it will just make the situation harder to get over.

What does the windmill do?

A windmill is a machine that is powered by the energy of the wind. It is designed to convert the energy of the wind into more useful forms using rotating blades or sails.windmills served originally to grind grain, though later applications included pumping water and, more recently, generation of electricity. Recent electricity-generating versions are referred to as wind turbines.They are used for generating electricity.

Is there wind on the moon?

With no atmosphere and no magnetic field, the Moon's surface is exposed directly to the solar wind. Over its 4 billion year lifetime many ions from the solar wind have become embedded in the Moon's regolith. Thus samples of regolith returned by the Apollo missions proved valuable in studies of the solar wind

What direction are faucets supposed to turn?

Answer

It depends on the manufacturer.

Answer

If they are "fluted" handles (uniform throughout their perimeter), they should both turn clockwise to shut off. If they are "wing" handles (a blade sticks out, somewhere on their perimeter), then the wings should push outward to turn off, and inward to turn on. In other words, the left handle turns clockwise to shut off, and the right handle turns counterclockwise to turn off.

What is the basic working principle of air conditioner?

Air-conditioning BasicsAn air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freonevaporation cycle are the same in a refrigerator as in an air conditioner. According to the Merriam-Webster Dictionary Online, the term Freon is generically "used for any of various nonflammable fluorocarbons used as refrigerants and as propellants for aerosols."

Diagram of a typical air conditioner

This is how the evaporation cycle in an air conditioner works (See How Refrigerators Work for complete details on this cycle):

  1. The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas (red in the diagram above).
  2. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.
  3. The Freon liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas(light blue in the diagram above).
  4. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building.

Mixed in with the Freon is a small amount of a lightweight oil. This oil lubricates the compressor.

So this is the general concept involved in air conditioning. In the next section, we'll take a look inside a window unit.

Who makes the largest swing keel sailboat?

The largest "swing" keel "production" yacht (ie. keel pivots/rotates into hull) is probably the Northshore Southerly 54rs. They have only just started construction, so if this does not count, then the next model down the 46rs is probably the biggest. Draught varies between 7 foot, to less than 3 foot with the keel up on the 46rs and it can be beached.

In terms of "custom" designed yachts, the Bill Dixon Yacht Design Company have made a 100 foot yacht with a swing keel named Liara II (Liara II actually has a tubular keel, meaning the lower half of the keel with the bulb is lifted into the out keel casing. It works in the same way a telescope does. But large yachts can accommodate swing keels). Coincidently, Bill Dixon designed the (hull) Southerly 46rs as mentioned above.

As for yachts with "lifting" keels (ie. keel moves vertically upwards) the biggest production may be the Hanse 630e which as the name suggest is 63 foot in lenght. Marten also producte a lifting keel yacht I belive. Wally have adjustable boards, as do products of many of the larger builders but it could be argued that these are custom, rather than production models as they all vary.

As for custom yachts, adjsutable boards are fairly common, the biggest may be Mirabella V, her draught can vary between 32 feet and 13 feet. Mirabella V is 247 foot in lenght and set numerous records upon completion of construction in terms of size, sail area, mast height ect.

The Southerly 57 is on the water at Southampton Boat Show and there is a 65 on the way.
