For nearly as long as people have harnessed wind to perform work, it has been used to move water from one place to another. Whether used for agricultural irrigation, wetlands drainage or pumping water from wells, wind machines have long been a relatively cheap and easy way to pump water, particularly in off-grid applications where electric alternatives are (more…)

KiteGen thinks that current wind technology only scratches the surface of what’s possible with wind energy. That’s because wind turbines cannot reach higher and touch altitude wind. Rarely wind farms are sited at more than 100m above the ground; the higher they go, the heavier, more unstable and expensive the apparatus becomes. (more…)

An Australian company called Renewable Energy Solutions Australia Holdings Ltd. (RESA) has created what it says is a super quiet and efficient wind energy turbine.

Suggestively called Eco Whisper, the wind turbine employs 30 smaller ones capped with a specially (more…)

In addition to the high legal fees and exposure to potentially hefty damages payouts that accompany allegations of intellectual property infringement, such lawsuits can also be dark clouds over defendants, hampering their ability to do business.

A salient example of this in cleantech is the news that (more…)

With the rapid growth of the wind power industry in recent years, and the expected continued expansion to meet EU targets by 2050, the sector is in danger of suffering a skills shortage throughout the various types of employment within the industry.

The EWEA’s wind at work report of 2009 concluded (more…)

I’ve written extensively about the patent infringement and antitrust litigation between wind power rivals GE and Mitsubishi (see, e.g., previous posts here and here).

While that legal battle spans multiple venues, encompasses several different patents, and includes (more…)

In what is emerging as a major green IP story, not just of technology but of international intrigue, American Superconductor (AMSC) recently filed two lawsuits against its erstwhile customer, Chinese wind energy system maker Sinovel.

Both cases involve allegations that a former AMSC (more…)

The Washington Post’s assertions today about the Department of Energy’s loan programs today are both incomplete and inaccurate.

Here are the facts:  over the past two years, the Department of Energy’s Loan Program has supported a robust, diverse portfolio of more than 40 projects that are investing in pioneering companies (more…)

Back in February we released the preliminary results of a patent landscape report, which identified both historical and future trends in the horizontal axis, utility-scale wind turbine industry.

We now have a more comprehensive view of those trends as a result of the analysis on the landscape of (more…)

Most people think of massive wind farms when they think of wind power. But there’s a small revolution going on, and one that some people are, quite literally, screaming from the rooftops about.

One small wind technology recently appeared in Time Magazine’s list of Top 20 Green Tech Ideas. (more…)
