Backyard wind turbine? There's an app for that

Now you can test whether you're both techno-chic and an ecogeek by combining the iPhone with home wind turbines.

Small wind turbine maker Mariah Power has teamed up with software developer Create with Context to make an iPhone application designed to measure wind speed.

The application, which is due "any day," uses the iPhone's microphone to get a read on wind speed. It translates that into how much power a small wind turbine could offset. For example, a wind that averages 12 miles per hour is enough energy to run your refrigerator and freezer for a year, according to Create with Context.

The application was written to get people excited about wind power. But it strikes me that actually buying a turbine based on an iPhone application is a bit risky.

Small wind turbines do indeed work, but experienced wind installers will tell you that they only deliver on their stated performance when there is a sufficient wind. That means placing a turbine far above and away from obstructions, such as trees and rooftops, in addition to getting that 12-mph average wind speed.

Two studies--one in the U.K. and one in Massachusetts--found that early buyers of pole-mounted wind turbines and roof-mounted turbines did not get the electricity output they expected. The primary reason was that the turbines weren't getting enough wind in their locations.

So an iPhone wind speed application could be fun to play with and even give you a decent idea of wind speed. But if you're serious, I'd suggest consulting a wind map from 3Tier or others and gather more data with an anemometer.

There are at least two other iPhone applications for measuring wind speed, called Wind Meter and Wind Speed, the New York Times notes.

Worthless app.

on the iphone? shocking!

Want to spend money on an Iphone, then an App, then a Wind turbine, just to find you still don't get power due to a guy mowing his lawn during the test?
There's an App for that!

Some of Martins comment and reporting are really right on target.
NREL ( National Renewable Energy Lab ) was testing Mariah Power's Windspire Giromill small wind turbine at the National Wind Technology Center (NWTC) through January 14, 2009 when NREL terminated its testing.

Interesting to know how iPhones will help us learn more about wind power! This application is indeed a great way to detect wind speed. As you know wind energy has great potential and the generation of electricity in the United States is targeted to reach 20% in the near future. Pacific Crest Tranformers will give you more information related to wind energy. Here's the link http://www.pacificcresttrans.com/home.html
