Neverland – Windmill

Introduction

There are a lot of tutorials on Internet, especially on Youtube, about how to make a “Diy Windmill”. All of them use recycled materials as bicycle wheels, plastic bottles or old pieces of wood and iron. The methods described are very helpful, and of course, very smart systems. The chosen about which one is the best is based, first of all, on what you prefer, then, which kinds of row materials you have at home, or you can get easily, and finally, which one is the simplest to build. In the following pictures there are shown some example of wind turbine do it yourself (Figure 1).

As you can see from the pictures above the windmill could be divided in two types: vertical axis windmill and horizontal axis windmill. In the present guide I have chosen a vertical axis windmill because is easier to build then the other method. Infect, in order to use a system with a horizontal axis, it should be used an instrumentation to transfer the energy from the horizontal axis of windmill to the vertical axis of alternator. It is not very hard to make but I think that it is always better start with an easy things because they surely will be more difficult afterwards.

In conclusion the present guide will describe the method how to make a vertical axis windmill, and in particular, the row materials used to make it are two tanks of 55 U.S. gallon (circa 200 l). The next picture shows as the wind turbine will be at the end of work (Figure 2).

Mechanical parts

First of all to make the wind turbine, as mentioned in the last paragraph, we need to find two barrels of about 200 litres. The first operations is to slide them in two parts then join in order to have like “helix”. They are joined together with a 3 inch PVC circle as shown in the following pictures (Figure 3;Figure 4).

The second step is to create the unit that allows the barrel helix to spin. It is composed from 2 units of ball bearing, one in the top and one in the bottom of the barrels, joined at 2 pieces of timber about 9 square inch with a hole in order to put a 3 inch pipe (Figure 5).

The last step is to put a 3 inch pipe trough the two tanks, and then, to connect the ball bearing systems. The length of the pipe depend how high are the barrels, but considering that the tanks are high about 1 meter, the total length of the pipe should be like 2,5 meter. The next picture shows how it is the final product with the pipe (Figure 6). When we have the completely wind turbine, it should be fixed in the wood structure explained in the chapter before. Once installed the wind turbine in the pallets structure, it has to be connected at the alternator and the all electrical parts to produce the energy. All the electrical part will explain in the next chapter.

Electrical parts

Building your own windmill turbine requires a number of items. A windmill, a structure of supporting it off the ground, a motor, an energy smoothing system and an inverter if you want to use your wind turbine generator to power equipments. Each of these parts needs to work efficiently in order to generate energy for your generator. We will discuss the parts and how to assemble a wind turbine in this D.I.Y. Guide.

The structure to support the wind turbine off the ground is substantially a wooden construction that allows the motor to be close to the barrels and connected with them through a gears; they transfer energy from the vertical axis to the power generator. The simplest method in order to do gears is to use a normally cutting boards, maybe recycled, and cut them with saw to cut plastic. Another method to make gears could be a 3D printer, but it is not a very common and easy to have at home.

The gears are manly of two dimensions: first one is, connected at the vertical axis with a pvc pipe, bigger then the second one, merged to the motor. As mentioned before they must be connected together to transfer the energy from the windmill to the motor or alternator. In the follow pictures you can seen the gears and how they should assemble (Figure 8;Figure 9).

Once built the gears and their connections, it is time to attach them and the motor to a piece of wood close to the windmill system somehow. The location of the motor is critical and you may need to make a very good mounting point suitable for the windmill axis, cause the energy generated depends how efficiently are the whole system. The pictures below shown how could be the connection between the mechanical and electrical part (Figure 10; Figure 11).

The motor used is a permanent magnet (pm) motor (Figure 12). There are a number of others methods using car alternators or stepper motors, for my opinion, the chosen is based on what type of power generator you can find easily. I have considered a 24 V, 250 W motors which run at 2650 rpm creating 24 V, comes from an old scooter. It is designed to spin when the electricity is passed through it. However, if we spin the motor, we can create electricity and use the motor as a generator. The speed at which the motor is revolving (the amount of rotations through 360 degrees undertaken in a set time) normally measured in revolutions per minute (rpm) is directly proportional to (increases and decreases) the output of the pm motor. Assuming the wind continues at a constant speed downhill gear creates a larger voltage output for the motor than an uphill gear.

There are a number of options for smoothing electricity in a wind turbine generator system. The following described method is with a led acid battery. The battery can be used as capacitor that smooths the voltage output from the motor, so the battery has the function of capacitor with the added benefit of providing long term energy storage. Again it is possible to over charge battery which can not result battery fizz. For a 12 V lead acid battery the voltage across the system should be kept between 12 and 15 Volts.

Finally, if you are wishing to use AC mains powered appliances you will need to purchase an inverter. A power inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). There are two types of inverters. A pure sine wave inverter creates a smooth AC output. A quasi sine makes a square wave, but some device may not work with quasi sine so the chosen is required in a pure sine inverter. Inverters are designed to work with batteries so they usually work with voltages between 9 and 14 Volts.

In order to connect the device each other I have chosen to use a 30 A “Anderson Connectors”. The connectors hold a good connection but are also designed to pop easily, if you trips on a cable for example, so you do not damage any soldering.

Neverland – New Wooden Construction

In the chapters above there are summarized all the steps on how to build “Neverland”: a “DIY” power energy pallets structure. It includes two systems to provide energy: a windmill and a solar panels station. At first I thought that the structure around the vertical axis windmill could be built using disassemble pallets, in fact, three pieces of wooden boards, in each pallet, must to be taken off to allow the air to enter in the structure and moves the windmill inside. After some analysis I understood that maybe the open space in order to enter the air it is not enough, then the new idea. The structure around the windmill system should be always with the woods of pallets, but this time with an open structure and not with a disassembled pallets. The air without obstacles enters inside in a better way and can offer more air to the windmill and this is could be translate as more energy. The following picture (Figure 1) shows the new structure.

“Most of our industries generate massive amounts of waste. For every tone of municipal solid waste, there are 71 tonnes produces from mining, manufacturing, and product distribution. We have nuclear waste, soil laced with heavy metals, chromium-contaminated groundwater, landfills bursting with cast-off plastic containers. The residues of our consumption are buried in highly centralised areas and are burned when the volume accumulates”.

The problem of waste disposal is becoming one of the main problems on the environmental: landfills, incinerator and indiscriminate abandonment of waste are real social and environmental emergency. A really serious problem that cannot remain indifferent.

Since this moment I have never heard about the concept “Blue Economy”. A week ago I started an intership in the “Blue Economy Solutions” in Berlin, then I read some articles about innovations and, as citied before, the Blue Economy’s book. I am very surprised, the ideologies behind the acting are simple: try to produce less waste and pollution as much as possible, trough the inspiration of Nature with own hands.

I have a Master’s Degree in Environmental Engineering, furthermore my background taught me how it is important that everybody collaborate to change the world, then I found this kind of approach very clever. Now I would like to share my idea in order to have advices from somebodies more specialized then me.

As mentioned in the title my idea is a station with a vertical axis windmill and two solar panel on top. There is not nothing new about the idea, but I believe the most important aspect is: we can do the station in mode “do it yourself”, with recycled materials or, in the worst case, with second-hand items. The structure could be made with pallets, the windmill with a used tanks and the energy solar system with “diy” solar panel. Could be interesting because everybody can make a station like this and have a “free” energy which can be used to charge electric cars, a lawn-mower or simply a computer when you want use it in garden. I enclose a simple image of my idea.

In conclusion, this is a prototype and of course it needs a modification to work well. So I am very happy if somebody is interested in to develop the project. I am working in it, thus I will update you with new ideas and modification.

Blue Economy Report about El Hierro

El Hierro is the most Western of the seven Canary islands and declared a Unesco biosphere reserve in the year 2000.

Renewable energy on the Canary Islands | Global Ideas

Within Europe, Spain is one of the leading nations when it comes to the use of renewable energy. One of the government’s goals is for the El Hierro, one of the Canary Islands, to soon become 100 percent reliant on clean energy from wind and hydro power. If it were to reach that goal, El Hierro would be the first island in the world to meet its energy needs without burning any fossil fuels. Find out more next week.

An energy turnaround without subsidies is possible by 2020

An energy turnaround without subsidies is possible by 2020

The phasing out of nuclear energy by 2020 is only feasible and financeable by using renewable energy.

ZERI: an energy turnaround without the aid of subsidies is possible by 2020.

(Berlin, 13th May2011). The phasing out of nuclear energy by 2020 is only feasible and financeable by the use of renewable energy. So is shown in an innovative scenario from the Zero Emissions Research and Initiatives (ZERI). Prof. Ernst Ulrich von Weizsäcker supports the model: “Through the intelligent combination of existing technologies the energy turnaround can succeed by social consensus, and with financial gains”.

“The expansion of renewables will be economically successful, when we use existing technologies and material cycles in the established infrastructure” explains Gunter Pauli, founder and chairman of the ZERI Foundation, at the presenatation of this energy scenario in Berlin. The massive expansion of a decentralised, regenerated energy supply will therefore be possible and viable, without triggering social opposition. “I am thrilled with the method” says Prof. Ernst Ulrich von Weizsäcker, former President of the Wuppertal Institute for Climate, Environment and Energy. “The intelligent combination of simple energy sources creates synergies and efficiencies”.

With the use of these synergies, electricity can be produced  from renewable energy sources at costs so low, that the funding of the expansion will be unnecessary. The use of innovative technologies for wind, solar and bioenergy is more than a faster and more lucrative way out of nuclear energy: “the phasing out of nuclear energy results in great opportunities to create jobs in Germany and to achieve a worldwide leadership in technology” explains Anne-Kathrin Kuhlemann, director of ZERI Germany (ltd?)

Gunter Pauli´s scenario is based on three, already proved, technologies:

1.    Windpower without plant construction: vertical wind turbines that are installed in existing pylons make the construction of additional wind farms unnecessary. If one third of the 150,000 pylons in Germany were equipped with vertical turbines, up to 5 gigawatts could be provided. The cost amounts to about 5 billion euro.

2.    Biogas efficiently and as storage: Biogas generators enables the efficient extraction of biogas through a combination of agricultural waste and sewage sludge. If 500 of Germany´s 9,600 sewage treatment plants equipped with this, 5 gigawatts of electricity could be provided to the basic energy supply, with total investment costs of roughly 10 billion euro.

3.    Solar Energy without Subsidies: The third technology is a combined electricity and heat production through double-sided Photovoltaic panels. With a lifespan of over 20 years the costs per kilowatt hour are below one cent. The investment for a targeted capacity of 5.4 gigawatts is around 10 billion euro.

Through the combination of these three technologies it will be possible to produce energy at a cost considerably lower than by nuclear energy at present. With a price difference of 3.6 cent per kilowatt hour there exists-from replacing 15 gigawatts from nuclear energy-a saving of 4.7 billion euro per annum. Calculated on a running time of eight years, investments amount to around 25 billion euro in savings, compared to the amount of 38 billion euro. Through these savings, the capital requirements for the necessary investments should be covered, and in this way finance Germany´s phasing-out of nuclear power.
