looking-up-to-windspire1.jpgWhile the vast majority of U.S. wind generation comes from massive utility wind farms planted across stretches of our nation’s wind-blessed land, a few startups are beginning to offer smaller scale, lower-cost turbines that can fit into more compact spaces and are geared at a less commercial type of customer.

Mariah Power, a Reno, Nev.-based company that makes a 30-foot tall, $4,000 turbine, is one of the startups that’s been making some headway with its lil’ wind gear. The company raised a Series A round from The Sierra Angels of Incline Village, Nev., and The Keiretsu Forum of Lafayette, Calif., and announced recently that the Department of Energy’s National Renewable Energy Laboratory will be testing its wind turbine.

The company is hoping that the propeller-free design and of its 1,800 kilowatt hours per year “Windspire” turbine will help push forward the small-scale wind movement. According to the American Wind Energy Association the small scale wind industry, which is defined as 100 kilowatt capacity or below, has been experiencing major growth in the past decade and hopes to grow at 18 to 20 percent through 2010.

Mariah says its customers only need roughly 11-mile-per-hour average wind speeds, and half an acre of land. And the company says the $4,000 price tag is about half to a third less than other renewable power options.

Last month, Marquiss Wind Power said it had raised $1.3 million in a Series A funding for its uniquely designed small-scale rooftop wind turbines. Their Aeropoint product is based on the “ducted wind turbine,” is just under 20 feet tall and boasts a square-shaped frame, and is intended for businesses that want to add a bit of clean energy to the mix.

newearth1.jpgIn November we interviewed the CEO of the San Diego-based small-scale wind makers New Earth, Ian Gardner. He told us the company, which makes the “Helix Wind” double-helix designed system (see photo), was looking to raise a Series A round “in the neighborhood of $3 million to $5 million,” for its vertical-axis design. It’s pretty slick looking, no?

The established firm in the mix of newer players is Flagstaff, Ariz.-based Southwest Wind Power. The company has been selling its small-scale wind hardware for two decades, and says it’s already sold more than 100,000 of its more traditional-looking turbines.

Southwest sells its turbine gear through dealerships (many can be found in California) with prices ranging from $600 to $3,000. Our own Alexis Madrigal actually spotted one of Southwest’s turbines in the urban Mission district of San Francisco (check out the video, if you haven’t already).

So who’s buying up this wee wind? Businesses and remote residents that want to go clean and save some money in the long term, as well as niche industrial applications like backup power for telecommunications towers. The American Wind Energy Association says the U.S. leads the world in production of small wind turbines.

But the technology still makes up a tiny part of the overall U.S. wind-generation market, with average commercial turbines offering between 1.5 MW to 2.5 and even 3 MW. In reality, wind systems aren’t yet DIY enough to easily install on your own, nor do they work very well in areas that don’t have a lot of land.

That’s what these startups are trying to do, to come up with better designs that can shrink the systems, and make them safer and easier to plug in. As climate change concerns turn renewable energy into a hot topic, more residents and small businesses are looking into how big of an impact small wind can make.

  1. I really look forward to the day that these wind technologies can be used effectively in urban and commercial applications.

  3. This is too cool. The possibility of eliminating the need for my electric company has always been the driving force behind my fascination with wind power. These little turbines could be applied to every private home in the world and totally power our individual needs as well as supply the needs of buisiness and manufacturing on a smaller scale, and be more beneficial to each of us than some nasty belching smokestack that continues to harm in the pursuite of continued cheap energy. Too the future!

  5. I was reading Paul Gipe’s book, “Wind Power”. Two ideas I picked up from that are (1) non-conventional turbines generally don’t work out; and (2) height of the tower is everything.

    So I would be very leery of the first 3 windmills mentioned. Will they hold up over ten years? Will they even put out enough energy to make up for the energy used building and installing them?

    RE height: we have trees here, so you want to be at least 80′ for an effective wind turbine. I think there is a quote in the book from Mick Segrillo “too short a tower is like putting solar cells on the north side of the roof”.

    I think few home owners would be willing to go high enough for an effective system (if they even have a site that allows it). I live on a farm and am considering wind energy, but it seems to make the most sense for larger (10kW and up) turbines 120’+ high. And that gets into serious money.

    I would also be getting triple use from the tower, using it for my wireless Internet business, and for amateur radio antennae. Still iffy on cost/benefit!

    1. did you ever put in a wind system? If so, what did you go with and how is it working for you.

  6. John is right about so many practical concerns. Didn’t we start with Leonardo Da Vinci or even earlier to figure out how to use wind? What happened to all the lessons learned about failed designs.

    Also, to be competitive, CapEx needs to be $3000/kW installed (commercial wind power). Based upon the data given Mariah Power clocks in at $20,000 per kW. This does already not work for PV at that rate… But I am sure there are rich dot.com kids that love to waste their dough..

  8. Green energy is definitely the best solution in most cases. Technology like solar energy, wind power, fuel cells, zaps electric vehicles, EV hybrids, etc have come so far recently. Green energy even costs way less than oil and gas in many cases.

    [...] We recently profiled four wee wind startups all working to generate a few extra kilowatt hours off local breezes. In urban areas, zoning restrictions often limit one’s ability to throw up a 35+ foot turbine, which explains why, for example, San Francisco Mayor Gavin Newsom has formed a work group to examine the feasibility of wind power-generation in the city, and, the Mayor hopes, amend the building codes.
