How To Make A Wooden Wind Turbine?

Wind power has only recently become a source of toxic waste that winds up in landfills, thanks to the introduction of plastic composite blades in the 1980s.

Larger wind turbines may now be built nearly entirely out of wood, not just the blades, but also the remainder of the structure, thanks to new wood production technologies and design. This would eliminate the waste problem while also making wind turbine manufacture less reliant on fossil fuels and mined resources. The wood for the next generation of wind turbines could come from a forest planted between the turbines.

How do you build a wind turbine from the ground up?

  • Step 1: Print the wind turbine cutout after downloading the materials. Department of Energy of the United States of America.
  • Step 2: Remove the tower and blades from the model.
  • Step 3: Paint the tower and blades in different colors.
  • Step 4: On the tower, cut out slots.
  • Fold the tower in half.
  • Fold the blades in half.
  • Attach the blades to the tower in step 7.

Is it true that wind turbine blades are hollow?

The blades of commercial wind turbines are made of fiberglass with a hollow core, but aluminum and lightweight woods are also utilized.

What materials can be used to construct a wind turbine?

Wind turbines are generally constructed of steel (66-79 percent of total turbine mass), fiberglass, resin, or plastic (11-16 percent), iron or cast iron (5-17 percent), copper (1 percent), and aluminum, according to a report from the National Renewable Energy Laboratory (Table 30). (0-2 percent ).

Many turbine components are made in the United States and are sourced domestically. Wind turbine towers are 60-75 percent domestically supplied, blade and hub components are 30-50 percent domestic, and nacelle assemblies are over 85 percent domestically obtained, according to the Office of Energy Efficiency & Renewable Energy’s Land-Based Wind Market Report. Internal parts such as pitch and yaw systems, bearings, bolts, and controllers, on the other hand, are frequently imported.

Is it possible for me to build my own wind turbine?

Perhaps you live on a boat, vacation in a secluded lodge, or, like me, live off the grid. Maybe you just want to save money on your electricity bill. In any case, you can create a homemade wind generator using a few low-cost, easy-to-find items, giving you access to electricity for as long as the wind blows. You’ll be able to light up that storeroom, power your barn, and keep all of your vehicle batteries charged with a generator.

Solar and wind power are used to power my off-grid cottage, which is powered by a bank of four 6-volt golf cart batteries wired for a 12-volt system. My system is protected from under- or overcharging by a charge controller and a battery minder. I spent less than $1,000 on the entire setup, which includes lights, fans, a television and audio, refrigeration, and a disco ball that rises for special occasions.

To power a home, how big of a wind turbine do you need?

Small wind turbines for home usage typically range in size from 400 watts to 20 kilowatts, depending on how much electricity you need to create.

Each year, a typical home consumes roughly 10,649 kilowatt-hours of electricity (about 877 kilowatt-hours per month). A wind turbine rated in the range of 515 kilowatts would be necessary to produce a meaningful contribution to this demand, depending on the typical wind speed in the area. In a location with a yearly average wind speed of 14 miles per hour (6.26 meters per second), a 1.5-kilowatt wind turbine will cover the needs of a home consuming 300 kilowatt-hours per month.

A competent installation can assist you in determining the amount of turbine you’ll require.

Create an energy budget first. Because energy efficiency is typically less expensive than energy production, reducing your home’s electricity consumption will likely be more cost effective and reduce the size of the wind turbine you require.

The amount of power generated by a wind turbine is also affected by its tower height. A skilled installation should be able to assist you in determining the tower height required.

Is it possible to use a car alternator as a wind turbine?

If you’re new to the idea of making a wind generator out of repurposed parts, you’ve undoubtedly asked yourself a few questions like these:

  • Why are automobile alternators suitable for wind energy?
  • What adjustments are required to convert an automobile alternator into a functional wind generator?
  • What is it about Delco-style alternators that makes them so popular?
  • Which WindyNation blades work best with Delco-style PMA wind generators?

Perhaps we asked that last question ourselves! In any case, if you’ve ever wondered about repurposing automobile alternators, now’s your chance to learn everything you need to know.

Wind power enthusiasts are increasingly common around the world, taking advantage of excess supplies of alternators or motors that were originally intended for purposes other than generating electricity from the wind. Fisher & Paykel washing machine motors are quite popular in Australia and New Zealand, as these machines utilise big permanent magnet motors. Ametek, Inc. is best known in North America for their tape drive motors, which were once readily available and immensely popular for constructing wind generators.

However, when it comes to DIY modest wind power, the Delco brand of permanent magnet alternators is likely the most popular.

Why are Delco-style Alternators So Popular?

The Delco moniker is derived from Dayton Engineering Laboratories Co, a long-time supplier to General Motors. Delco had a long and illustrious history, which included the invention of the first practical battery ignition system. Hundreds of key components for American-made autos were manufactured by the enterprise, which was absorbed into a variety of larger mega-corporations. GM still uses the Delco brand name, especially for its ACDelco components division, but the corporation has come a long way since its early pioneering days.

Since the early 1980s, the American auto industry has had a lot of excess production capacity, which has often gone into generating a lot of components that don’t always wind up in automobiles. Even though these alternators didn’t find a place under a hood, they found a way to be useful. Delco has experienced a rebirth among wind power aficionados. For usage in small wind generators, repurposed vehicle alternators have become exceedingly popular and relatively cost-effective.

Most ACDelco generators that are sold specifically for use as a wind generator have been repurposed or rebuilt. The reason for this is that when a Delco automobile alternator is employed in a wind turbine, it operates under different conditions than a permanent magnet alternator.

What Modifications are Necessary?

The stator of an automobile alternator is wound to function at extremely high RPMs, owing to the alternator’s luxury of being turned by a powerful, high-rpm engine. The operating rpm of a Delco vehicle alternator is around three times that of the crankshaft of the car engine. The crankshaft of a car rotates between 1000 and 4000 revolutions per minute. As a result, a Delco automobile alternator is built to provide adequate charging voltage and amperage at 3000-12000 rpm.

In 25 mph wind, a modest wind turbine with a rotor diameter of about 60 inches may reach 850 revolutions per minute! The threshold for a normal Delco automobile alternator to even begin charging a 12 volt battery bank is 850 rpm!

When using a Delco automobile alternator as a wind generator, it is imperative that the alternator be modified to run at low RPMs. This is achieved by two complex modifications:

  • The stator windings on a Delco vehicle alternator are replaced with a stator with more turns of lower gauge wire.
  • On the rotor, high-powered Neodymium magnets are used, which produce more power than conventional magnets.

Where Can I Buy Quality Delco Alternators for Wind Turbines?

WindBlue manufactures high-quality Delco Permanent Magnet Alternators (PMAs), and they are ethical and transparent in their assessment and presentation of the PMAs’ expected power output. They generally achieve this by displaying a Power Curve that shows the output of their alternators under load. This is in contrast to some other re-sellers of modified Delco PMAs that only show open-circuit voltage readings, which are essentially useless indicators of a PMA’s output.

Have Reasonable Expectations

When it comes to Delco alternators, it’s critical to have realistic expectations for the amount of power these devices will provide. In other words, you shouldn’t anticipate a Delco PMA to produce a power production miracle because the amount of power a wind generator or alternator can produce scales with:

  • The maximum amount of copper that can be crammed into a stator.
  • The number and size of powerful neodymium magnets that can be used on the rotor.

Because a Delco automobile alternator is about the size of a cantaloupe fruit, the amount of copper and magnets it can hold is limited.

A automobile alternator, maybe more importantly, was designed to be installed under the hood of a vehicle. This is not meant to be a criticism of their quality or even their suitability as wind generators. It is a basic reality that the specs for a car alternator and a wind generator are vastly different. A car alternator, for example, will not be weather-proof because it is normally protected from rain and mist because it is located under the hood. Second, the stator must be rewound in order to provide a voltage adequate for battery charging, as we’ve just mentioned. Third, because it is turned by the automobile’s engine, which may produce at least 100 horsepower (76000 Watts! ), a car alternator does not need to be particularly efficient at generating energy.

Great Way to Learn How to Build a Wind Generator

Nonetheless, we are heartened by the thousands of people who have learned the foundations of wind power via Delco PMAs and are now using them to generate significant amounts of electricity.

We’ve put WindyNation blades through their paces on a variety of WindBlue alternators, and we prepared this section to serve as a resource for consumers considering WindyNation aluminum wind turbine blades in conjunction with a WindBlue alternator.

On the WindBlue 540 and 520 series PMAs, we tested numerous sets of our blades. The load for all of the experiments was a 12 volt battery bank.

Three of our 28-inch HyperSpin blades performed admirably with the WindBlue 540. In 11-13 mph winds, we measured 2-4 Amps of power into a 12 volt battery bank. We measured roughly 10 amps of output into a 12 volt battery bank in very high gusts (20-25 mph). The 540 is ideally suited for the HyperSpins. The 540 PMA is wound for high voltages at low RPMs, allowing it to charge in low to medium winds. As a result, the unit’s Amperage output suffers slightly.

The WindBlue 520 worked best with the 5-blade HyperSpin set, which offers a good balance of torque and speed. This alternator produces more amps than the 540, but it takes a steady 9 mph wind to start charging a 12-Volt battery. The alternator was able to produce 3-5 amps in a 12 mph wind. The 540 produced 12-17 amps in 20-25 mph wind, which is a reasonable amount of power for a little PMA.

Overall, we were impressed with WindBlue’s alternator’s performance. If you’re dead set on employing a Delco for your wind turbine project, we recommend the WindBlue. If you’re looking for something a little more powerful, we recommend the Windtura 500 PMA.

Anyone can see the appeal of modified Delco automobile alternators for do-it-yourself wind power: LOW COST.

Thousands of DIYers utilize these devices to build modest, low-cost wind turbines all around the world. It’s critical to have realistic expectations regarding how much power a Delco-style alternator will produce when acquiring one. Furthermore, because the Delco alternator must be “rebuilt” for use in a wind turbine, it is critical that you obtain a Delco alternator from a reliable and honest company. A Delco car alternator that has been adjusted by an inexperienced person or a company that takes shortcuts will have poor performance, cogging, and will most likely fail on you.

What is the best wind turbine blade shape?

When compared to other wind blade designs, flat blade designs offer major benefits to the DIY’er. Flat rotor blades are simple and inexpensive to cut from plywood or metal sheets, ensuring that the blades are uniform in shape and size. They’re also the simplest to comprehend, requiring fewer design and construction abilities, but their efficiency and easiness of generating electricity are both poor.

Curved blades are similar to the curved surface on top of a long aeroplane wing (also known as an aerofoil). The curved blade has air flowing around it, with the air moving quicker over the curved top of the blade than beneath the flat side, creating a lower pressure area on top and, as a result, subjecting it to aerodynamic lifting forces that cause movement.

These lifting forces are always perpendicular to the upper surface of the curved blade, causing it to rotate around the central hub. The more lift produced on the blade by the faster the wind blows, the faster the blade rotates.

The advantages of a curved rotor blade over a flat blade include that lift forces allow a wind turbine’s blade tips to move faster than the wind, resulting in increased power and efficiency. Lift-based wind turbine blades are becoming more widespread as a result. Homemade PVC wind turbine blades can also be cut from regular diameter drainage pipes, which already have the curved curvature, giving them the ideal blade shape.
