Geothermal power is power extracted from heat stored in the earth and comes from radioactive decay of minerals and from solar energy absorbed at the surface. It’s used to heat up baths and for generating electricity. Geothermal power is cost effective, reliable, and environmentally friendly, but has previously been geographically limited to areas near tectonic plate boundaries.Geothermal wells tend to release greenhouse gases trapped deep within the earth, but these emissions are much lower than those of conventional fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed instead of fossil fuels. As of 2004, five countries (El Salvador, Kenya, the Philippines, Iceland, and Costa Rica) generate more than 15% of their electricity from geothermal sources.

It’s a big piece, but I hope you get all the info u need =)

1. The process of harnessing energy from the ocean’s tide is very similar to that of harnessing water through a hydroelectric dam. However, the dam needed for this process is much larger. Installed within the dam are turbines. The movement and flow of the tide in and out from the shore is then used to turn those turbines and create the power needed.

(2,3,4 question) There are two ways at present of using tidal power:

Barrage systems: This system, built like a dam across a river, holds back the water till the tide has gone out, then uses the potential energy of the water to turn turbines in the barrage. This is an expensive system with many disadvantages.

Tidal Stream systems. This consists of using turbines, rather like wind turbines, to use the kinetic power of the moving water to generate electricity. This is easier and cheaper to install.

There are three Barrage systems operating throughout the world.

One large 240 MW plant on the Rance River in France, and two small plants,

one in the Bay of Fundy in Canada, and

another in Kislaya Guba in Russia.
There is only one Tidal Stream system working commercially:

A fullsize turbine prototype, SeaGen, was installed in Strangford Lough in Northern Ireland in 2008, with a capacity of 1.2 MW.
A large number of smaller tidal stream pilot schemes are being trialled.

-In Hammerfest, Norway a turbine, generating 300 kW, started in 2003.
-A 300 kW Periodflow marine current propeller type turbine was tested in Devon, England in 2003.
-Since April 2007 a prototype project in the East River in New York City has been running.
-An Open-Centre Turbine, has a prototype being tested at the European Marine Energy Centre (EMEC), in Orkney, Scotland.
-A Gorlov turbine, an improved helical design, is being prototyped on a large scale in S. Korea.
-Neptune Renewable Energy has developed Proteus which uses a barrage of vertical axis crossflow turbines for use mainly in estuaries.
-During 2003 a 150kW oscillating hydroplane device, the Stingray, was tested off the Scottish coast.
-Successful commercial trials of highly efficient shrouded tidal turbines on the Gold Coast, Queensland, Australia in 2002.
-Shrouded turbines are being installed for a remote Australian community in northern Australia, two small turbines will provide 3.5 MW.
-Another larger 5 meter diameter turbine, capable of 800 kW in 4 m/s of flow, is planned as a tidal powered desalination showcase near Brisbane Australia in October 2008.
-The Hydro Venturi, is being tested in San Francisco Bay.
-In April 2008, a turbine-generator unit (TGU) prototype was successfully tested at Cobscook Bay and Western Passage tidal sites near Eastport, Maine.
-Trials in the Strait of Messina, Italy, started in 2001 of the Kobold concept.

(4,6,7) Tidal energy use harnesses the water flow created primarily by the moon orbiting the Earth. As water is pulled toward the gravity of the moon, currents are created that can turn generator turbines.

Volumes have been written about tides and their effects on our planet. This Wikipedia Tides article is a good primer on the subject. It is noteworthy that all tidal energy does not come from the moon. About a third of it comes from the gravitational influence of our sun.

The interplay of gravitational fields of the moon and the sun combined with the rotation of Earth, creates a twice a day ebb and flow of the tides of our world that varies in height and strength.

Those variations in height and strength are completely predictable. As we’ll see later, that predictability is an important aspect of tidal energy use.

Though renewable, practical tidal energy use will be limited. Tidal flows are global, but the key to using them economically is finding either natural high tidal flow areas, or large tidal basins that can be easily dammed to channel water through turbines. _________________________________________________________________

ENVIRONMENTAL FRIENDLINESS –

Tidal energy use involving dams creates many of the same environmental concerns as damming rivers. Tidal dams restrict fish migration and cause silt build up which affects tidal basin ecosystems in negative ways.

Systems that take advantage of natural narrow channels with high tidal flow rates have less negative environmental impact than dammed systems. But they are not without environmental problems.

Both systems use turbines that can cause fish kills. But these are being replaced by new, more fish friendly turbines. The art and science of environmentally friendly hydro engineering is well advanced and will certainly be applied to any tidal energy project.

But even with dams, the environmental impact of tidal energy projects may prove to be smaller than our use of any other energy resource. Economics will severely limit the number of tidal energy projects. ______________

I don,t have any plans on paper but, they sell windmills as decorations on landscapes. Look them over and see if they have a shaft with two pillow blocks so you can attach a pully. Then go to an auto junkyard and get an old 12 volt generator. Put a pulley on both the windmill shaft and the generator, ( which of course will already have a pulley on it), then an appropriate belt to connect them both. If you have the knowledge, you can wire in a voltage regulator.

To protect the system from over speeding in excessively high winds, a centrifical throwout clutch could be attached to the end of the windmill shaft.

Hope this helps, and good luck.

Well, they have to be about 30 feet above any surrounding buildings or trees, they have to be two tower heights distant from any building and they must fall entirely on your land should they fall in any direction so unless you have an acreage, you’re not getting a wind turbine.

Do it yourself turbines from the 70’s were typically made with an automobile alternator and therefore the maximum power ratings were about 720 watts with them. A quick look at the wind turbines listed on Amazon shows that most are about 450 watts and some are 750 watts. Keep in mind that you can only expect production 1/6 th of the time, the most you would get out of one of the larger turbines would be about 1/10th of the average home energy use.

You will need blades for the wind to turn, a generator to produce power.

1) DC electric generator, to charge batteries directly and run DC
appliances or inverters run from batteries to give you AC current

2) AC synchronous generator. These AC generators get field excitation directly from your electric company so if the electricity goes down from the power company, so does your generator. But the good thing is they are synchronized with the Hz of (60Hz) and you don’t need an inverter to and batteries to smooth out the sine wave of current and voltage. You get a steady 60 cycle current.

3) regular AC induction motor.This will produce electricity that has to be used on the spot (converted to heat water or something) and has variable frequencies depending on rotor speed of turbine. But it can be run thru diodes (just like car alternator) to convert to DC to charge batteries. And then the batteries are run to power DC equipment or run thru an inverter for things that need AC

Are you good with math and sciences? You could go about this two different ways. You could go the more techincal route or you could go the more hands-on route.

If you are more techincal you could look into going into Electrical Engineering. This is not an Easy major so you would have to consider that in most cases this a 4-5 year investment. However you would learn about most of the principles behind how we generate, route, and use electricity. You would also learn the skills needed to design some of your own ideas. If you don’t have 4 years to spend learning. This may not be an option. Electrical Engineering requires you to go through all of the maths… (algebra, trig, Calc 1-3, Differential Equations, etc…) also all of the basic sciences, Chemistry, physics, thermo dynamics, etc.. And then onto your EE courses. Once you have your batchelors degree you can take your EIT (engineer in training) test or equivalent. After a few years experience you can then apply to take the PE (professional Engineer) test which would allow you to design, build, and sign off on projects. (a requirement in most states)

Another route would be to go to a 2 year Tech school for electronics or to be an electrictrian. These would give you a more hands-on knowledge of how physically connect and work on the devices you are interested in. You may not learn how to design a system but you could sure hook one up. This may require you to get an apprenticeship with an established electrician but it would provide good experience.

Hi Yves, I’m sure there are many websites that can give you better answers so try google too, Yahoo is limited. If you look on ebay you will see lots of permanent magnet 24 volt DC motors for use in scooters, I use one of these, the 250watt model, to power a 12 volt sound system, it can deliver 10 amps at 15 volts. For a wind genny you may have to put gearing between to get the right rpm.
I don’t know if you plan to use a voltage regulator, but if you only intend to use a blocking diode, the best one is a Schottky type, there is a cheap twin 15A schottky from Maplins under £2. I use both 15A diodes in parallel so they won’t get hot & need a heatsink.
The Schottky diode has a voltage drop of just 0.2 volt, I think you put the decimal place wrong
For wind generators the recommended battery charging voltage is 13.8Vmax so 14V with the diode. Car alternators usually produce about 15 volts minus 0.6V for the rectifier, so charge at 14.4 volts. Rutland voltage regulators for wind gennies operate at 13.8volts to stop the battery over-charging.
I don’t know why charging voltages are not the same for a car and a wind genny battery, I’m inclined to think any voltage from 13.8 to 14.4 is ok.
Batteries can deliver a huge current possibly causing burns and starting a fire, so it’s essential to put a fuse in the circuit, right next to the +ve terminal is best.

Axial Flux Alternator

The axial flux alternator (sometimes called a generator), is the heart to many diy wind turbine projects. While a small permanent magnet, D.C. Motor, such as the Ametek 30, makes for a very quick and simple project assembly, these motors are becoming very difficult to find and quite expensive. Ebay is loaded with people selling D.C. Motors for home wind turbine projects, that simply will NOT work, due to the extremely high RPMs required to get any usable output. Thus a homemade axial flux alternator may be your best alternative.
What is an Axial Flux Alternator?

A permanent magnet alternator generates power by passing magnets past a group of coils of wire. The magnetic field that surrounds a magnet is call it’s flux. Axial Flux simply means the lines of magnetic flux that past through the coils of wire, travel along the “axis” of the turning motion. The other type of magnetic flux in an alternator is called RADIAL FLUX and it occurs when the flux occurs “around” the magnet. Pictures are worth a thousand words:

Radial Flux

Axial Flux Alternator

In the left picture, the yellow disk is the stator. The two bluish plates rotate, along the horizontal axis, past the stationary stator. In the image to the right, the stator is on the case. The rotor, on the axis, rotates “inside” the stator. This guide by Hugh Piggott describes the process in good detail – How Axial Flux Alternators Work

Overview of the Complete Process – Building an Axial Flux Alternator

In February 2001, Hugh Piggott created a guide for building a permanent magnet generator (PMG) (alternator), after being commissioned by the British government. This guide remains in the public domain and provides an excellent overview of the complete process. You can build a PMG from these plans, though these instructions continue to be improved upon. The PDF document can be downloaded here: PMG Manual

This manual describes how to build a ‘permanent magnet generator’ (PMG). We can
also call it an ‘alternator’, because it generates alternating current (AC). Continued…

admin answers:

Hey Michael, Ben is correct about the vertical type turbines. The reason none of the power companies use them, is because they are horribly inefficient. Most of the energy absorbed by the downwind blade is used forcine the upwind blade back into position for the next cycle, and very little is left to produce power. Typically, this type of wind turbine, called a Darrieus Rotor, is about 5 to 8 % efficient, meaning less than 1/15th of the winds power is converted into useable torque, or electricity, and the rest is just wasted churning the blade around in the wind. Horizontal units, and in particular the 2 or 3 blade units generally operate at about 30 to 35 % efficiency, or about 6 times more efficient than a comperably sized Darrieus Rotor. The smaller home sized units like ours have a tail that constantly turns the unit to face the wind regardless of where it is coming from. Older farm type turbines with 12 or 15 blades on them usually worked this way too. That type of turbine, with the multitude of wide flat blades were almost never used for electrcity generation, they were also not very efficient. In most cases, they were used to pump water, and in that way what was needed more than efficiency was low wind start up torque. The large multiple blades worked better for this, but tended to stall out in higher winds. Electrical generating wind turbines work much better in high winds and at high RPM’s, so fewer blades is ideal for this.

The really large utility sized turbines you see that have no tail are either fixed to face one direction where the wind is almost always blowing from, like along the coast, or they have a small anemometer on top that senses the winds direction, and a computer uses a small gear motor to physically turn the unit to face the wind if necessary. These are typical in the midwest. Darrieus Rotors, and their close cousin, the Savonius Rotor, are really neat looking devices, and they are great for small garden pond pumps or outdoor garden lighting, but they are ill equipped to produce enough power to run even a household refrigerator. There is a great article at the American Wind Energy Associations website written by Mick Sagrillo about this, if you want to learn more, check it out. Mick is considered by many in the renewable energy world to be the modern day guru on wind power. Take care Micheal, Rudydoo

Solar panels currently being manufactured, have a design life of 20+ years.

Home-size wind turbines have a wide range of design lives. The turbine life is influenced by conditions of use — high winds, ice on the blades, etc.

I would recommend that you purchase your home-scale wind turbine from a seller who offers a guarantee to repair or replace the unit if it fails under normal use. A 5-year or 10-year guarantee period would be ideal.

There is no such thing as a device that can generate energy from nothing. So called perpetual machines are announced every few years with great fanfare but they always turn out to be frauds (or in rare cases honest but careless mistakes).

You can generate electricity from a ‘free’ source like sunlight or tides or wind or waves or geothermal heat, but you can’t generate electricity from nothing. To do so violates one of the fundamental laws of physics, the conservation of mass and energy.

Very convincing sales copy can make you believe in such devices. For instance, I remember reading a few years back about a ‘Genesis’ energy generation system that used a catalyst to split water into hydrogen and oxygen while using just a tiny bit of energy; then the hydrogen and oxygen were used to generate electricity through a fuel cell, and almost all the electricity produced was available, only a tiny bit was needed to split more water. This is malarkey and anyone with some basic physics knowledge will know it’s impossible, but it didn’t stop the company from claiming it had over 100 reputable scientists on its staff or board of directors. A good way to get some start-up money – sell some stocks to uninformed investors, then cash out before the house of cards collapses.

To make an electrical generator, you need to have a length of wound copper wire rotating inside a magnetic field (refer to elementary physics).

Gasoline/diesel/etc. Generators run basically like your car’s engine, but instead of turning wheels, it uses the motion to rotate the wire inside the magnetic field, producing electricity. Remember, energy can’t be created or destroyed. The chemical potential energy in your combustible fuel is being converted to kinetic energy, which is being converted into electrical energy.

A wind turbine is more “free” in that you don’t have to go out and buy drums of oil to make your electricity. But it works on the same principle, but in this case, it’s the turbine blades catching the wind that spins the copper loop, creating electricity.

As far as your batteries go, you may be able to store it there, but to charge any battery, from AA to car, you need the correct circuit and voltage, or nothing will happen. So you probably can’t use your batteries. But if you can, all that you an do is store the potential energy there, and use it at a later time.

But if you just want to play with making a generator, try this:

First, you need to choose the energy source that you want to convert into electricity. You can use a stationary bicycle, a water wheel, wind turbine, a bored child willing to do some menial work on a set of gears, or virtually anything else with a rotating axle. You do have to choose the source, because as I said – you can’t get energy from nothing.

Take that copper wire that I talked about, and make that loop that I also talked about, but leave two ends free (you need that to form the electric circuit). The larger the number of turns in the loop, the more electricity you can generate for the same amount of rotation. Kind of like an electric pulley system, to use a bad analogy.

Take your loop, and connect it to your energy source. You need to be able to rotate the loop end-over-end, without twisting the two connecting wires about each other, because if they do, you’ll get a short circuit, and boom, it’s done. One way to successfully accomplish this is to connect one wire to the rotating axle and the other wire to a conducting “brush” that maintains contact with a second conductor.

Make sure that you’ve sufficiently supported the loop so that it’s out of the way of any moving parts of the energy source (such as your legs and the pedals if you pay a seven year old to ride a bicycle that never goes anywhere – give them one of those hand-held video games, they’ll never notice). To make sure that you get this right, you may need to reinforce your loop with plastic or another light (but sturdy) material.

Grab some magnets (permanent magnets), and arrange them around the loop so that the loop can rotate freely between them. Take care to ensure that you arrange the magnets to maximize the field strength. One good and simple method is to make the south end of one magnet face the north end of another.

Stick the two conductors on your energy source to a battery, circuit, chainsaw, whatever it is that you want to drive. Again, you need to keep your wires separate to avoid a short circuit, so you’ll need to use some kind of brush mechanism again, or whatever more clever thing that you can come up with that I haven’t considered.

Poke the kid and get him to start peddling, or release your turbine to the wind, whatever you want. The amount of energy that you get from your turbine will depend on the efficiency of its construction, materials used, and how much mechanical energy us put in to drive it and spin the turbine itself (a faster peddling kid will give you more electricity than a slower one).

Run with it. A home-built turbine is unlikely to provide your house with any really useful power, unless you’ve really taken some time, money, and thought into it (which is possible). But you might run some simple things from your standard knock-off generator, such as perhaps basement lighting, that kind of thing.

I work primarily on Boeing products, so my answer is from that perspective.

Short answer: GTCP331

Commercial aircraft use an Auxiliary Power Unit (APU) that provides electrical power and pneumatic pressure. The electrical power can then be used to run the electrical pumps (ACMPs)to pressurize the hydraulic system.

There are also Ram Air Turbines (RATs) that deploy directly into the air stream. This “RAT” looks like a trolling motor you would see on a boat, the wind spins the propellers and generates hydraulic pressure. If you have pneumatics, you can use the Air Driven Pump (ADP) to get hydraulic pressure. If you have hydraulics, but no electric, you can use the Hydraulic Motor Generator (HMG) to get electrical power.

There are backup systems all over aircraft these days. Most of which are activated automatically in the event of a failure of another system. The crew may only get an annunciator light to inform them that a backup system has been activated. No further action necessary.

A wind turbine is basically an electric turbine on top of a stand and with blades attached.

I would recommend you salvage a motor from a small electrical device. If you can find a small fan, then you only need to put it on a stand of some sort to make a wind turbine because it all ready has a turbine and blades.

An electric generator is just an electric motor in reverse. So any device that has an electric motor can potentially be used to make a turbine.
