For all you suburban dwellers, alternative energy is finally finding its place in or on your home! Most commonly when we think of wind power, we think of industrial wind farms in the country. Well, wind power is again retreating in size, making it available for the most modest home.

Mariah Power of Reno, Nevada has developed a new efficient and attractive wind harvesting station called the Windspire that has a quite attractive profile for suburban dwellers. The Windspire, at 30 feet tall and 2 feet wide, takes advantage of the access of vertical space you have out on your suburban lot. With only a ½ acre of land or more, the Windspire will work effectively. The 1 kW inverter will produce about 1900 kW hours each year in 12 mile per hour average winds. The Windspire even includes an internal wireless modem that will continuously communicate with your computer about the amount of power is generated in your backyard while at work, sleeping, eating, and generally going about your day. This allows you to track and check the generation progress at any time.

The propeller construction is different from more common wind turbine. The vertical construction allows propellers to turn at the same speed as the wind. This allows it to be virtually silent and safe for both birds and people. In addition to the safety and tranquility, at only 30 feet in height, it is below most residential and urban zoning restrictions. And at a tall height in the sky, it is responsibly easy on the eye. The design is sleek, light, and simple. Available in customizable colors and designs, you can even appropriate the construction for your own aesthetic tastes.

With simple and complete installation, the kit is an easy addition to the home. Priced at only $3,995, the lowest cost of anything of its kind, wind power immediately becomes an affordable commodity. In addition to providing the product, Windspire’s site has a useful tool for clients and potential clients. The tool helps you evaluate your site and appropriate the installation to be the most effective.

So, if you have been looking for a way to incorporate alternative energy in your home but always thought your site wasn’t appropriate, think again. With sleekness and silence, your neighbors will only be intrigued.

As alternative energy is coming of age, new designs and more inventions are making it easy for you to install alternative energy generations stations at your home. A West Australian designer is working on a turbine system invention small enough to be installed on your roof. At a meter in length and a half meter in height, this invention is even easier to apply to your household energy consumption (and production). Keep your eyes open, pretty soon we will be able to put a turbine on our car, belt, and bike to generate usable amounts of energy.

Designer Scott Amron has created a catalogue of conceptual products designed to persuade people to use less energy, or at least think about how many things are plugged into sockets in their homes. The experiment is called "Die Electric," named after the insulating properties of a dielectric material. A dielectric is a substance that is highly resistant to the flow of an electric current. The experiment is about powering down, and rethinking the function of electrical components for purposes other than jacking up the monthly electric bill.

The first set of experiments transforms messy power cords into functional household items: "Shelf" (image above) and "ToothHold." Depending on where the outlets are in your home (usually at a functional reaching level), you now can use this cord to have reachable necessities throughout the home. Whether you are reaching for a toothbrush or a book, your outlets are put to greater use. Thinking beyond common functionality, maybe you can even use this shelf as a seat…

The second set of experiments are nothing but aesthetic wall dressings. Their titles insinuate the additional meaning: "Grow Plug" and "Single Vase AC." These houseplant retrofits cover up tacky wall outlets while adding an element of fresh-cut or freshly-growing nature to the room.

The third, and my personal favorite, is simply titled "Off." This is a light switch hook designed so that the it only functions as a hanger when switched to the "off" position. The switch is still fully functional, but the added bonus encourages you to think about your actual lighting needs.

Designer and experimenter Scott Amron has performed and exhibited a large portfolio of functionality experiments incorporating basic principles of engineering and physics while challenging their common conceptions. One outstanding project among these is called "Brush and Rinse," which won a Best of Category award in this year’s I.D. Annual Design Review, a highly acclaimed annual design competition. Scott has a B.E. in Electrical Engineering, and is a declared freelance electrical engineer, designer, conceptual artist, inventor, and founding principal of Amron Exptl.

Check it out. His products don’t cost you your shiniest penny, and they will provide your houseguests with a challenging surprise.

As an extension of last weeks post, Vote on Sustainable Design for the Future, there are simply too many design competitions out there: we must alert you to more. Many of these design competitions are open to people of all disciplines with good ideas. So maybe you should take a pen and paper and enter a keen green idea of your own if you want to see the world change.

Here is my deeper perception on additional “call for entries” situations:

What I have found is that when a corporate product manufacturing company has a call for entries, they are seeking new ideas. Sometimes ideas perpetuate in a work situation, and it becomes difficult to think as far out of the box as some younger creatives do. Electrolux is an international home appliances and equipment company. Each year their Design lab runs a competition for industrial design students working towards their undergraduate or graduate degrees (so this one isn’t for everyone but its still interesting). While “innovative ideas for household appliances of the future” is the mainstay, sustainability is this year’s theme. Students are asked to create eco-friendly, sustainable household appliances and solutions for 2020. If you are a student, check it out. The deadline is July 31. For the rest of you, finalists will be announced October 1.

When a foundation posts a call-for-entries, it is often based on a desire to generate the inspiration of the organization’s namesake in a new generation, and to allow the his/her spirit to live on. Each year, the distinguished jury of the Buckminster Fuller Challenge awards a large sum to “support the development and implementation of a solution that has significant potential to solve humanity’s most pressing problems in the shortest possible time while enhancing the Earth’s ecological integrity.” This year’s competition honors Fuller’s a"nticipatory design science method": the idea of doing more with less. The Challenge seeks “design science solutions within a broad range of human endeavor that exemplify the trim tab principle. Trim tabs demonstrate how small amounts of energy and resources precisely applied at the right time and place can produce maximum advantageous change.” The entry period is September 4 – October 30, so you have a little time to think about this one. On the other hand, a sustainable solution cannot be left until the last moment to be completed. So get to work.

My third example is similar to one of last week, but this one is still open for entries. RE:VISION is a complete competition network that seeks to highlight great ideas about to explode, but that don’t yet have a venue to do so. Stacey Frost, founder of RE:VISION, wanted to create a place where these “ideas are put into action, supported and encouraged by a diverse group of people dedicated to making WHAT IF, WHAT IS.” Stacey believes that with each individual’s unique perspective combined with ideas, energy, and resources we can really generate change.

The current competition RE:ROUTE is a call for new urban transportation systems thinking. “We need to enhance and revitalize our areas, changing them from a bunch of buildings into a community. How can we move people cars, services, or goods through a neighborhood.” The competition seeks to generate new and creative ideas for urban transportation that start 4 steps back from the base and stop for a breath of fresh air 100 steps ahead of where we are in 2007. The competitions closes August 15 but the requirements are minimal. If you have an idea, get on the “wagon” and redesign it.

For more information these are the sites I consult for new competition posts:
Core77

American Society of Interior Designers

In the design world, often times young architecture/design firms and even individual designers will apply to competitions during the young part of their career to get public recognition, build credentials, and experience the social circuits around design.

As a young aspiring designer myself, I have made a keen observation of the design industry this year. Many of the call-for-entries and competitions this year have been for solutions related to sustainable development, energy, climate, biodiversity, environmental degradation, etc. Naturally we would expect these type of call-for-entries to come through the EPA grant programs, the NRDC, and other governmental organizations for the environment. Instead the call for action is coming from design firms, architecture magazines and other NGOs alike.

Allow me to take this opportunity to highlight some of the forthcoming competitions and competitions past that have sparked interest in publications of all sorts. The entries to these competitions not only alert us to solutions most of us have never thought of, but through the venue of these competitions many will have the opportunity to be realized! The following are just a few examples of the aforementioned. Look out world, great solutions are coming!!!

Design 21: the Social Design Network, is a mainly internet based collaborative project between the global design and merchandise company- Felissimo; and the United Nations Educational, Scientific, and Cultural Organization (known as UNESCO). They seek to inspire social activism through design- design for the greater good. “We connect people who want to explore ways design can positively impact our many worlds, and who want to create change here, now.” Design 21 has been hosting international competitions since 1995 mostly based around social themes.

This year, one competition called Heated Issue, was a call for an environmental campaign; another was for an educational “Childs Play” toy that encourages children to cultivate their own imagination; and the third, Shelter Me, is for a new design of a natural disaster temporary relief shelter. The competition award recipients were voted on by the public, and the winners were just announced! So go ahead, view the future!

Metropolis Magazine: an architecture, design, interiors magazine has strongly directed its focus towards sustainable development in design over the last few years. Annually, they host a design competition called the Next Generation Design Competition that awards $10,000 to the winner and they choose a list of runner-up proposals that get published as well. This year the competition focused on solutions for ENERGY reduction, consumption, efficiencies and alternatives. The award recipients this year designed a city streetlight that conserves urban energy based on the lunar cycle. Check it out. Metropolis also just announced next year’s theme: WATER.

Droog Design: an international design collective based in Amsterdam, seeks to “create innovative concepts that change perspectives." This past month they had a call for entries for concepts based on Climate Change. As a result of picking a winner, they hope to develop a product that pushes boundaries, changes perspectives of environmental issues, and invent new experiences, interactions, and participations… How exciting. Droog will select the top 10 designs, and the public will be able vote online to pick the winner. Public voting begins in September, so look it up and get your vote on.

Aside from the competitions calling specifically for sustainability conscious and socially responsible entries, many award recipients of internationally acclaimed annual design competitions are being recognized for their environmental awareness. Competitions such as the ID Annual Review, the Red Dot Design Award and the Spark Awards. This interesting progression is to be noted among the design circuits as a landmark in sustainable development. Lets hope that this is not the trend of the year but an annual progression towards more socially and sustainability conscious design and cradle-to-cradle conscious products.

Build it beautiful

In honor of the holiday and the American Dream of freedom and exploration, I am going to help you declare an “energy independence” today (at home anyway). Today, we are going to decrease our dependency on finite natural resources such as coal and natural gas used to generate much of the energy we consume in this country. The interesting lesson is that these finite resources are burned to generate steam that drives a shaft through magnets, resulting in an electromagnetic inductive reaction that generates electricity; the same principles on which wind power is generated.

Today’s topic to shout from the mountaintops is how to make your own affordable wind turbine. Did you know that the energy in the wind more or less follows the human 24-hour power consumption cycle? So I’m here to say, lets utilize that wind while we simultaneously use up the electricity.

I have personally not built this mechanism, but being a declared experimental designer, I like to rig things up and love to figure out how things work. Thus, I have reviewed many instructions and debriefed for you an informative and simple process from a Do-It-Yourselfer in Arizona who built his for under $150. If you crave more specific instructions, visit his site or one of the many options at the bottom of the page. There are hundreds of ways to build each sub-construction, so get creative and think about efficiency in weight, size, and aerodynamics.

Without further ado, following is a simple and cheap process of instructions on how to build your own wind turbine at home!

The bare necessities that every wind turbine has in common:
1. A Generator
2. Blades
3. A mount and wind vane to keep it turned to the wind
4. A tower to put it up in the sky
5. Rechargeable batteries and an electronic control system

With that said we will follow these 5 recommended steps to simplify your way to a great affordable turbine.

1. The Generator
First, the heart of the whole mechanism: the generator. An electric generator is quite simple when you refer back to your knowledge of physics. To put it simply, the generator will convert the mechanical energy in the wind intercepted by the blades and into electrical energy. If you want to learn how a common generator works inside, refer to this site. To get the basic principles of electromagnetism, refer here.

Generator Shopping:
Many electric motors work as generators, as they function the same fundamentally only in reverse. Instead of outputting a voltage from the crank of a shaft, a motor would crank the shaft from an applied voltage. The only problem is that many motors have to be driven much faster as a generator to reach their rated voltage.

I am told that Ametek motors are the best for home built turbines. The Ametek 99 voltDC, although large, is the best one they make. But word on the street says it’s a hard one to find, so if you can't find the top dog, don’t worry, they make many alternatives as do other companies.
The best advice for motor/generator shopping I can give you is look for a motor that is rated for:
1. High DC voltage
2. Low rpm’s
3. High current

If you’d like to leverage the properties of the different Ametek generators visit this site!

Another great motor I’ve heard a lot about is the MiniGen Motor. Although it doesn’t have a huge power output, it is small and can serve as your hub to attach your rotor blades to directly. It outputs AC power so when you get to the electronic controller stage you will need a rectifier instead of a blocking diode.

Once you’ve acquired and decided on your generator we are ready to move on to the blades.

2. The Rotor Blades and Hub

Many people use ABS, or PVC piping. You can carve your own out of wood, which I have done, but be sure to use as light a wood as possible. If you want to get real slick and sexy, you could use styrofoam and carbon fiber, but those materials are neither sustainable nor healthy. A great site to refer to while constructing aerodynamic efficiency is the Danish Wind Industry Association.

With a plastic pipe 6” in diameter and 24-36” long depending on the intended scale of your project. This is what you want to do (scale is set for 24” blades).
1. Cut the pipe into 4 equal parts around the circumference (you only need 3)
2. Cut the blade at the angle you prefer (usually about 20 degrees)
3. Sand the edges to maximize the aerodynamics
4. Next you need a hub to bolt your blades onto (4-6” diameter hub will be perfect) with a hole in the center that will fit the motor shaft.
5. Mount the ends of the blades onto the hub with screws and bolts each 120 degrees from the other.
6. If you can find a plastic half sphere to cover the front of this construction, it will improve the airflow therefore the efficiency of the unit by directing air into the rotor blades.

3. The Mount

The mount and wind vane are important because they hold all the parts and direct the blades into the wind. The wind vane or tail is the balancing tool of the mechanical energy operation. It keeps the turbine from capsizing, therefore sacrificing harvestable wind.

1. It is easiest to use a 2×4” piece of wood about 35” long. This measurement can be imprecise as long as it fits the motor and is long enough to allow the vane to work with ease, so feel free to use any scrap lying around. Again, it is important to keep this whole construction light. This will facilitate movement of the mount in the direction of the wind.
2. Mount the motor to one end of the 2×4 so that the motor shaft is fully extended beyond the end of the wooden mount. (It is a good idea to cover the motor with something to insulate it form weather conditions-metal electrical boxes work as well as a piece of PVC pipe.)
3. Mount the rotor blades and hub construction onto the motor shaft.
4. Next, Wind Vane: All you need is a rigid piece of material to stand up about 8 inches and extend down the mount about 14 or longer. This is the mechanism that really controls the direction of the turbine. It is very important. Although the rotor blades can catch the wind and aid turning the construction in the right direction, the vane does this with much more ease. (Common materials are sheet aluminum, plastic, or even a thin wood. If you want to go green and creative- find a piece of flashing that’s laying around, cut up an old plastic binder, or cut up the lid to an old Tupperware container. [Note: all these materials are very light].)
5. Cut a groove in the wooden mount just wide enough for the thickness of your chosen vane material.
6. Slide it in. If it’s not tight enough, glue it into place to secure stability and function.
7. Add a weight of any sort to the bottom of the wind vane end on the 2×4. This will be your counterweight to the generator. You can use a lead weight (although not a magnet), a sand filled balloon…

An alternative to this construction is to find a 2 ¼” pipe or something large enough to fit the generator into. Insert the generator. Attach the hub to one end. Cut a slit in the other end in which to insert your wind vane. You can also place your counterweight inside the pipe. This construction is a bit sleeker in appearance.

4. The Tower

The height of your tower will be highly dependent upon your location in this world. If you live amongst many a canopy of tall trees, you will have a lot of interference to compete with. If you live on the plains, the wind will “go whipping o’r the plain” freely and quite low in the sky.

What you need for the tower is a long pole with something that functions as a bearing at the top to allow the mount to turn freely towards the wind. These are the step-by-step instructions from Michael Davis of Arizona who scratched his head at the local home center store over this for a couple hours. I think his solution is quite functional yet the resistance/friction on the bearing could be lower and more efficient.

1. Attach a 1” pipe fitting to the bottom of the generator end of the mount about 7-8” in.
2. Screw a 1” diameter, 6-12” long pipe nipple into the pipe fitting
3. Slip the pipe nipple into a 1 ¼”, 10-20’ conduit (depending on your locational interference).

With this construction you can drill a hole in the 2×4” mount and feed the wires from the generator right down through the pipe fitting, through the nipple, down the conduit, and out to the control system.

4. Find a scrap piece of wood that is about 2×2’. This will serve as your base.
5. Make a U shaped assembly out of 1” pipe fittings and pipes.

The Tee construction will function as a hinge that will allow you to raise and lower the tower.

6. In the center of the assembly put a 1 4” Tee. Insert in it a 1 ¼” close nipple, a 1 ¼” to 1” reducing fitting, and a screw into that a 1” diameter, 12” pipe nipple.
7. Drill a hole in pipe nipple, large enough for the wire to come out from the conduit.
8. Next drill holes 1” in diameter in the base platform that line up with the pipe fittings. This will allow you to drive shafts into the ground to stabilize your platform. The shafts will extend from the earth into the parallel components of the U construction, thus grounding the tower!
9. Attach 4 guy-lines to the conduit about 10’ up. Tie a rope to each line. Anchor each rope 90 degrees from the other in the earth with some stakes. Make sure these are secure, as you don’t want your turbine to come tumbling down. If you see this unnecessary then skip the whole u construction and anchor the conduit directly into the ground.
Mike's Base Construction

5. The Controller System

Here comes the interesting part that takes a bit of research, but once you do it step by step it all begins to make sense. The controller stores the power created by the spinning turbine and sent down by the generator.

Here are the items you need, what they do, and how they work:
1. First the power sent down from the generator is stored in one or more small batteries.
2. The surplus power is sent out to a larger storage/load when the primary batteries get fully charged, because they will.
3. A 40 amp blocking diode. These are one-way valves that allow the charge to be pumped in but not back out. This prevents the batteries from powering the generator as a motor and spinning the turbine voluntarily. If you use an AC motor you will want to use a rectifier instead. Rectifiers capture the peak and trough of an alternating current. I referred to this earlier in the generator section.
4. A charge controller. The controller monitors the voltage in the batteries and decides where the power from the turbine is needed and should be stored. If you are savvy with wiring up your own electronics this site will show you detailed diagrams of circuit construction and a couple links to help you out. If you don’t want to go there, then search eBay or some of the sites below for a wind power controller. Our friend Mike in Arizona built a fully functional controller, check it out.
5. The cord. If you have an old extension cord, dysfunctional on one end, perfect! If not find some insulated electrical wire with a decent size gauge (¼ – ½”). Attach a couple spade lugs to each end. Attach one to each output on the generator. Then thread the chord through the conduit and connect the spade lugs on the other end to the controller unit.
6. A 120-volt inverter. This is very important because it allows you to use the DC power generated. You will connect this to the battery load unit. It converts the 12V DC power stored in the batteries and into 120V AC power. From this you can plug in any household device you would plug into the wall: your computer, a toaster, a lamp…
Going Further Bonus: you can get a digital or analog computer-interface multimeter (can be found at Radio Shack or your local Electronics supply shop) that will connect to you computer for data logging!
Ahhh, I think I pretty much covered it all. Now that you have all the parts put together, you have yourself a beautiful turbine that initiates or enhances your independence from the communal electric power grid!

I challenge you to get as creative as possible in your project. In my research, I saw project constructed of 100% reused materials. It isn’t difficult, you just have to dig a little bit deeper. Maybe the shape or material you need is in that object you just put in the recycling bin, or even better in the trash. I also saw collapsible and portable turbines to take camping and on road trips. Here are a couple sites that I hope will inform and inspire your project:

How I Home-Built an Electricity-Producing Wind Turbine

Also, get creative on how you hook up the power supply. You could connect it to your water heater or your electric oven. You could rig it up so you have multiple removable secondary loads. Use the secondary battery packs to take inside and power your computer throughout the day or your telephone (but don’t forget to take the inverter too). If you think you are harvesting enough power, look into connecting it to the power supply in your home. If you are not quite there yet don’t worry, the experiments have just begun. Have fun, and please let me know if I can direct you to additional information.

Unplug it Mr. Independent: image courtesy or unplugart.comEvery object on this earth has an embodied energy. What is accounted for in the embodied energy is the whole energy life cycle of the object: the energy captured in the raw materials, and mostly all the energy required for the processes associated with it. Included in this calculation is the energy required to dispose of or decompose it. A tomato, for example, has a low embodied energy compared to that of a set of silverware, or a Lazy-Boy chair. Lets take an apple for example. Although they are grown in all 50 states, the average apple travels 1,555 miles to get to Chicago’s central market. Due to transportation costs, it seems this food has a higher embodied energy than necessary.

We Americans consume a lot of energy. Many of our appliances, such as our toothbrush, razor, and clocks, have become unnecessarily electrical, all consuming energy from the electric grid daily. If your energy bill has become morbidly obese, you are not alone. The average American family produces 15,000 pounds of carbon emissions each year. Imagine the damage we do just one single hot holiday! So, aside from supporting local and alternative power generation, here are a few fun things to do today to eat, drink, and celebrate your way to electrical independence today.

1. Go around your house and unplug all of the unused appliances, all those hidden clocks and battery packs on your coffee maker and chargers are constantly sucking our electricity.

2. Go to the lake and allow the kids (or yourself) to go swimming and wash up for the day rather than taking a shower.

3. Drink a local beer or wine. At least the transportation energy is lower than those coming from Australia or Sicily. If the average American mean travels 1500 miles to get from farm to plate, at least you can do your duty with recreational consumption. I mean with your liquid bread.

4. Eat raw. Keep the oven off and the house cooler. Make a batch of Gazpacho (with seaweeds for protein) and a raw chocolate mouse for dessert. Try it, its surprisingly spectacular!!

5. For you electricity independent lovers, check out the aphrodisiac qualities of raw foods and have some fun.

6. Sun brew tea. It takes a few hours but it keeps the stove off and gets you that vital caffeine. You can even try coffee in a filter sealed up on top. Or put your press pot out in the sun for a couple hours before you press it.

7. Play outdoors, where little electrical energy is required in order for you to expend your own. Stay clear of the shopping mall, the movie theatre, and, dare I say it, maybe even the bar. Instead, pack a picnic, go for a walk in the park, on the beach, or out in town, go for a swim at the lake, or play a game- you can even make one up! An added bonus: being outdoors is downright good for your health.

8. Ride a bike or walk if you need to get somewhere. If you can’t get there by foot or pedal, reconsider whether you really need to go or not! If you do, go to the park and ride and utilize as much public or unplugged transportation as possible

9. Build a bonfire instead of retreating into your lit up home tonight for cocktails and celebration. Gather around a bonfire and burn some old scrap wood.

10. Sweep up at the end of the day rather than turning on your vacuum.

Without further ado, I will let you get creative with your unplugged adventures today and I hope the residual of each engaging and enchanting option carries through to tomorrow.
