Are traditional residential wind turbines too expensive? Did you know you can build your own wind generator for less than $200 with Power4Home. Help the environment and save money!

Although we haven't exhausted the list of available residential wind turbines, I wanted to make you aware of another direction you could go. A little bit more adventurous and not nearly as expensive, you could build your own residential wind turbine. It's amazing when you do a little bit of research and find out a lot of people are doing just that!

There are many resources available to guide you through the process step by step. One such resource is titled: Home Made Energy. The gentleman who wrote the book is Bill Ford and he doesn't just want to teach you how to make your own turbine ... he wants to teach you how to do it on the cheap! He promises to show you how to build your own residential wind turbine (1,000 watts) for less than $150.00 and a 3,000 watt wind turbine for about $220.00! That also includes the instructions and cost of building the tower.

I haven't read the book or gone through the process of building one of his turbines, but he claims you can make the three blades required for free in about an hour. He also provides tips on how to find a free forklift battery and recondition it for your power supply. He gives tips on what kind of generator you need and how to get the best prices.

Another resource available is Power4Home System to build your own wind generator. The author's name is John Russel and he claims that other plans he's seen are just too complicated. He promises easy to use instructions that will show you exactly how to build your own residential wind turbine (1,000 watts) for less than $200.00.

Freetricity is a company based in Hemet, California introduced their new residential wind turbine, the Freetricity E2D Windmaster. The E2D Windmaster is a roof-mounted turbine at a very reasonable cost.

Freetricity lists five different WindMaster Wind Turbines on their website ranging from $1399 to $3499. The E2D 12 Volt DC System is touted as "The perfect starter system" at a very affordable price of $1399.00. The E2D 24 Volt DC System is priced at $1699.00. Branded as "The Rolls Royce of battery based systems", the E2D 48 Volt DC System is listed at $2299.00. Although not currently available, the E2D 1800 watt Grid Connect System will come with a price tag of $2999.00 and the E2D 2500 watt Grid Connect System is available at a cost of $3499.00.

From the news release announcing the WindMaster product line:

"WindMaster is available in four different power packages. The Grid Connects unique design is the most convenient system and supplies the most kilowatt-hours of power of all the packages. Simply mount the wind turbine to your roof, wire it to the grid connect inverter, and wire the inverter into the supply panel. The power generated by the WindMaster is supplied to your homes supply panel first; however, if it generates more power than you are currently using it will spin your meter backwards. Your electric company will then give you credit or cash for the power you generate."

"The 12-Volt, 24 and 48-Volt packages are battery-based systems. They charge the battery first then supply the users home with the stored voltage and current through a DC to AC inverter. The 12-Volt Basic package is the starter system and because it is easy to regulate the output of the WindMaster, it can be upgraded to any other E2D system. This upgrade ability applies to all system packages and is unique to the renewable industry."

UPDATE: August 31, 2012

A little update on this company, Freetricity is no more. After numerous complaints (see comments for some examples), the company was apparantly charged with various felonies in 2010 and their website (http://www.freetricity.com) is no longer active.

Mariah Power, based in Reno, Nevada, is the manufacturer of the Mariah Power Windspire. Their uniquely-designed Windspire turbine stands 30 feet tall with a radius of only 2 feet. Windspire, touted by the manufacturer as being "distinguished by its sleek propeller-free design, ultra quiet operation, rugged construction, and affordable pricing", is listed at $3,995.00. Other benefits listed on the company website include: ease of installation, ease of maintenance and high quality.

In a unique marketing twist, Mariah Power suggests using Windspires "in an array" and in essence creating your own mini wind farm.

Residential

"Use one or more Windspires to power your home. Place them in the back yard, or display them in front of your home. Line a path, driveway, or your entry, using Windspires as power-generating pillars. Great for homes in the country, but also appropriate for many suburban and urban settings."

Business

"Set up an array of Windspires in front of your building to provide you with electricity. Use this attractive form of renewable energy to visibly display your corporation's values and environmental responsibility, while lowering your energy bills."

Kinetic Sculptures for Resorts, Hotels, Office Towers, etc.

"A group of Windspires arranged artistically in an array, painted with custom colors, can form a novel display of renewable energy that provides usable electricity, visual appeal, and a strong message to passers-by. Take your outdoor display to a new level by incorporating Windspires."

Another unique feature of this particular turbine is a built-in wireless modem.

"Sometimes it can be nice to know how much energy you’re producing each month, let alone how much you made from that big windstorm last week. A click of your computer can provide you all of that. The Windspire has a built-in wireless modem that’s always transmitting power production information. Any computer with a WiFi modem can pick up the signal within 330 feet and read the output. It doesn’t get any simpler."

UPDATE: August 31, 2012

Reviewing my posts today, I tried to go http://www.mariahpower.com and was redirected to http://www.windspireenergy.com. The company and the technology have survived and it appears to be thriving, but the company name changed to Windspire Energy Inc. back in 2010.

Here's an explaination from the company website.

On April 5th, 2010 Mariah Power officially changed its name to Windspire Energy Inc. The change was made to clarify confusion in the marketplace between the corporate name- Mariah Power- and the product name- Windspire. The name change simply reflects the corporation’s desire to be focused on its core product- the innovative Windspire wind turbine.

For more information on the company formerly known as Mariah Power Windspire, you can still access their website at http://www.mariahpower.com.

Marquiss Wind Power (MWP), based in Folsom, California, manufactures a unique series of ducted wind turbines called MWP Aeropoint Turbine. These turbines stand 19 feet tall, are square in shape and were designed for use on rooftops in a commercial or industrial setting. According to their website, Marquis Wind Power is targeting commercial buildings of 1-3 stories in the United States to take advantage of "some of the windiest real estate in the country".

The three products listed are: the AeropointT500, AeropointT1000 and AeropointT1500. The AeropointT500 is rated at 5Kw and is said to work well in average wind speeds of 6-10 MPH. The AeropointT1000 is rated at 10Kw and is designed to work optimally in areas with higher average wind speeds. There are no details listed about the AeropointT1500, but it is scheduled to be released in the first quarter of 2009. Prices are not given for the Aeropoint series of wind turbines, but the manufacturer boasts an ROI of 2-7 years and payback twice as fast as solar. If those numbers ring true, there will be a bright future for this product line.

More details from the manufacturer.

"Marquiss Wind Powers’ product line is the Aeropoint series. These Ducted Wind Turbines (DFWT) stand 19 feet tall and are specifically designed to take advantage of commercial settings and turbulent wind flows associated with rooftops. MWPs aerodynamic design allows it to continue to re-orient itself to harness the changing wind flow directions and turbulence, while the ducted design and other patented technologies enable the turbine to effectively accelerate the wind speed as it approaches the turbine."

"These factors combine to allow the power output from the MWP turbine to exceed that of any traditionally designed comparable turbine. Depending on the power needs of a company or building, multiple wind turbines can be placed on a building’s rooftop."

UPDATE: August 31, 2012

I did a little bit of research and it appears as though this technology didn't live up to the hype. According to an article I found on bizjournals.com, the company discovered structural problems when installing their first turbines in the middle of 2008. Marquiss went on to acquire another company and hire a new CEO, but the original box-shaped turbine design was scrapped and it's unclear whether the company is still operating in any capacity.

For more information, you can reference the article I found here.

If you have any more info on this company or the technology, feel free to post it in the comments.

Are traditional residential wind turbines too expensive? Did you know you can build your own wind generator for less than $200 with Power4Home. Help the environment and save money!

The Whisper 500 Home Wind Generator is a larger wind turbine developed by Southwest Windpower of Flagstaff, Arizona in the United States. The product was formerly the Whisper 175 and was completely redesigned in 2004 to operate optimally in extremely high winds.

This home wind turbine is designed to produce at almost any wind speed. The output can be as much as 500 kWh per month in average wind speeds of 12mph average wind speed. 500 kWh per month is enough to power an average home in California.

UPDATE: August 31, 2012

The Whisper 500 Home Wind Generator is now being sold at the Alternative Energy Store for $7,675.00 $8,247.00. Check out the product page for more information.

Additional information from the manufacturer:

"The Whisper 500 is NOT for the novice. Installation of the turbine requires concrete foundations and at times a crane to lift the wind turbine into place."

"Solar and wind resources often compliment each other. Generally when it is sunny it is calm and when it is cloudy it is windy. This complimentary effect is even greater during seasonal changes. During the winter and spring when the sun is at its least exposure, the wind is at it highest. A Whisper 500 during these periods is essential to keep your batteries charged and your lights on."

Here's a video of the Whisper 500 in action. It takes a little while to get going...

A helix wind turbine or helix wind generator is a wind energy system for the small wind market manufactured by HelixWind of San Diego, California in the United States. They define small wind as "typically just enough power to meet the demands of a home, farm or small business" and their two products are the Savonious 2.0 (a 2kW system) and the Savonious 5.0 (a 5kW system). The cost of each product is not listed on the company website and it appears as though the patent is still pending for the Savonious 5.0.

According to the company, the unique design of the Helix wind generator provides many advantages over other systems. These turbines can operate at very low wind speeds as their design allows them to harness wind from any direction. As the founder of HelixWind, Ken Morgan, explains in the video below, the turbines operate silently and do not provide the danger to birds that traditional turbines do.

The Skystream 3.7 Residential Wind Turbine was released by Southwest Windpower of Flagstaff, Arizona in the United States on June 27, 2006 and was named one of Time Magazine's best inventions for 2006. The product was touted as "the first fully integrated wind generator designed specifically for the grid-connected residential market" by the manufacturer.

"Skystream will change the way many Americans power their homes and take control of their energy costs," said Andrew Kruse, co-founder of Southwest Windpower. "Wind energy for the individual homeowner is finally main-stream."

Skystream is grid-connected, so it supplies power directly to the home power supply and contributes when the turbine is turning. When the turbine is not turning, the home is powered by the electric utility. According to the tech details for the product on Amazon.com, this small wind turbine delivers 1.8 kW rated and 2.4 kW peak power at 20 MPH wind speed. It provides 400 kW per month in a 12 MPH average wind and works in winds as low as 8 MPH.

UPDATED: August 31, 2012

The Skystream 3.7 Residential Wind Turbine sells used to sell on Amazon.com for $5,499.00 USD. It is no longer listed on Amazon, but is was carried by the AltE Store and then sold at GoGreenSolar.com at the list price of $6,212.00.  There are a few websites still selling the product online, but at this point I think many of the sales/installations are being made through the dealer network.

Once installation costs are factored in, initial investment will typically be in the range of $12,000 USD to $15,000 USD. Rebates and incentives reduce the purchase price significantly in some areas.

According to the manufacturer:

"Skystream 3.7 can pay for itself in 5 to 12 years. This payback period will vary and can be much quicker in states with investment rebates. It's anticipated that Skystream 3.7 will save the average homeowner $500 to $800 per year, based on 4,800 to 6,600 kWh produced per year and a $0.12/kWh cost of electricity. This output would provide 40 to 90 percent of an average home's energy needs. In states like Hawaii, where the cost of energy and wind speeds are both high, Skystream 3.7 can pay for itself in less than 4 years."
