Ducted fans are so easy to drive, watch the LIM being spun by a little fan
Here is proof ducted fans can be driven by a light breeze. The 24″ fan started the 2 meter LIM from a dead stop with no assist. When wind tumbles over the top of a building there is a velocity gain of 180%… so a light 8mph breeze becomes a viable 14mph energy producing wind if you place a ducted fan in its path. Wait til you see it operate in a Class 2 hurricane.
At right is the base complete with brake and access for the electronics
Rogue River Wind introduces radically new relativistic generator
Coquille, Oregon
Rogue River Wind, Ltd, (RRW) an Oregon renewable energy company has acquired the rights to a revolutionary new relativistic generator (REM) design. RRW is the developer of a ducted fan wind turbine, the V-LIM, capable of operating in low, high and turbulent winds up to Class 2 hurricanes. The V-LIM requires an equally robust, high bandwidth, direct drive generator capable of capitalizing on these powerful kinetic forces. The higher the RPM the more power the REM produces.
Until now modern generator technology began with Barlow and Faraday in England, and rather quickly matured through the dynamo into the recognizably modern generator by about 1900. The REM design represents the first radical design departure in generators since that time.
The REM has no inductive wound coils. Plasma or laser cutters cut continuous and precise shapes simplifying manufacture. There is no inductive steel significantly reducing total weight. The design incorporates a magnet topology that requires only 1/5 the neodymium used in traditional generators. As a low resistance device there are no heating or cooling concerns.
The generator uses no flux targets so there is no magnetic hysteresis. The generator has low internal loss and no thermal loss. The generator operates at a high bandwidth, requires low starting torque and has zero cogging. The direct drive generator can be scaled and stacked to replace existing generators in traditional wind turbines and eliminate the need for gearboxes and reduce the weight at the top of a tower by over 2/3. These combined features result in a 15% efficiency gain over contemporary generator designs.
The general topology can be elementally reconfigured into all different generator design aspects and parameters, from axial to radial. It can function as stacked element generator in a traditional BIG WIND megawatt power mode, or as the power-generating element in a wind turbine based micro grid configuration.
The REM can be used in a radial mode as wheel based motor in an electric vehicle design, or in water driven electrical generation modes. It can replace any traditional field coil or rare earth permanent magnet generator design in most applications, as an efficient coupling element between a mechanical power input, and an electrical power output. It can even be a stepper motor in a disk drive mechanism.
The generator is available for license in any application where generators are required.

The many pitfalls of manufacturing in the US
As stated many times on this blog, Rogue River Wind, seeks, for a multitude of reasons including rebuilding local economies to build its products in the US. Everyone wants jobs, right? So it ought to be pretty much a slam dunk to get production manufacturing done in America or better yet, Oregon, but consider the experiences of A123 lithium-ion batteries and Amazon’s Kindle.
The answer is a story of the obstacles to a rebirth of U.S. manufacturing, and of the tantalizing possibilities if such a rebirth could be achieved. For Chiang’s company has one foot in China and the other in the U.S., reflecting the forces that drive manufacturers overseas and the potential for a renaissance at home.
The obstacles here are rooted in the sad history of manufacturing’s decline in the United States: Despite the promise of Chiang’s batteries, many on Wall Street and in Silicon Valley were incredulous when he and other leaders at A123 asked for capital to build factories in America — Asia, yes, but Michigan, why would you want to?
Even more daunting, nearly all of the world’s battery manufacturing industry is in Asia, where plants can be built faster and supplies and equipment are much easier to get than in the United States. These days, it’s hard to find Americans who even know how to build a battery factory.
Rogue River Wind is certainly learning the complexities of taking a relatively simple device albeit one requiring precise tolerances in Oregon despite the clamber for green jobs. The US has lost control of its own innovation and hence its independence as it has outsourced manufacturing to foreign countries.
The story of the Kindle and its E-Ink technology shares another sad side of what has become of Yankee ingenuity.
…More salient today as an insight into America’s standing in a globalized production system may be the backstory of another consumer electronics sensation–Amazon’s Kindle e-reader–yet here the story has a darker hue.
This I learned reading an excellent forthcoming paper by Gregory Tassey, which referenced a very troubling blog post by the Harvard Business School professor Willy Shih, entitled “The U.S. Can’t Manufacture the Kindle and That’s Problem.” What’s the problem here? Well, according to Shih, the global distribution of Amazon’s production sources for the Kindle betrays a far less benign story of out-sourcing than did the iPod and one that suggests that it does indeed matter how and where U.S. firms locate their production.
Recognizing this, the Obama administration is funding billions of dollars through programs like the USDA to rebuild manufacturing jobs in the US but it isn’t obvious how these funds help a company like Rogue River keep innovation in the US.
Rogue River Wind is getting new website
Slowly, we are getting all those nit picky details that come with a business to develop a website. Still trying to get all the specs and images and photos up but it is moving along at last. Am developing a blog for those interested in talking about renewable energy, distributed energy and capacitive storage technology.
Here is a preview
Rogue River Wind update and a couple of pics
We are closing in on our pre-production prototype and I am lucky to have a great staff in operations. As part of the company goal to provide jobs for veterans three of the four members of our operations department have served their country. My VP of Operations was a Lt Commander with the Navy and managed a 7MW floating power plant and has a masters degree in systems engineering. He is well suited to implementing smart/microgrids with distributed energy sources like small wind and solar and has been instrumental in getting us from earlier prototypes to the production model.
We also have a former helicopter mechanic from the Army (you can imagine how he comes in handy with a turbine like the LIM) and a grunt from the Marine Corp (yes, my grunt). Last, but not least we just added a fourth member to operations who has had a dream of working in wind energy since he was 15. Am very proud of my staff and wanted to give them all a shout out.

V-LIM launch date coming soon!
All this time I thought research and development and prototype design was the hardest part (and believe me it isn’t easy), but the procedural side of launching a new product is pretty damned intense. The brain power required from conceptualization to production is not only extensive but the diversity required puts the old ‘thinking ten moves ahead’ process in a chess game to shame.
There are so many facets to consider and I am so grateful to have backers, partners, friends, lawyers, accountants and employees capable of contributing so much to this effort. This is both an exhilarating time and a critically demanding time but I love what I am doing and look forward to each 16 hour day.
These stills will be animated into some educational videos describing how the LIM works and placed on the Rogue River Wind website that is also being professionally designed.
The above is fun but there is also the nuts and bolts paperwork side, shareholder agreements, manufacturing contracts, procedural manuals and regulatory issues. Tracking regulatory changes and legislative issues like investor owned utility PG&E trying to make competition illegal.
The state wants to encourage power-company competition, green energy and lower rates with the Community Choice law.
So, how does Pacific Gas & Electric Co. respond to these threats to its monopoly?
The utility giant bankrolls a deceptive June ballot initiative that seeks to rewrite California’s constitution, kill upstarts in their tracks and block the expansion of municipal utility companies such as the one saving money for residents of Sacramento.
Considering that Congress hasn’t been able to accomplish much requiring a 60 vote filibuster proof majority rather than the old 51 votes, PG&E’s request to require two-thirds of voters to approve an alternative energy option, dooms renewable energy in California to painful and costly death. Grrrr!
Okay, back to business and the website will carry all our technical information soon and will provide an energy blog with updates just like the one above.
Rare earth shortages may put China in the drivers seat on green energy
As I have been writing for some time, China controls the rare earth magnet market. With the push for more wind farms and electric vehicles and China’s own growth in these industries, China may stop exporting except within a completed manufactured product.
“Countries and companies that have or plan to develop industries that need rare earth minerals to make products are concerned about China’s growing consumption, which they fear will eliminate China’s exports of rare earths,” said W. David Menzie, chief of the international minerals section at the U.S. Geological Survey (USGS).
China has also encouraged companies that use rare earths to locate their manufacturing facilities in China, Menzie told TechNewsDaily. But some companies fear moving because of concerns about intellectual property protection, he added.
China is fast becoming known, rightly or wrongly, as the king of IP ripoffs and few companies want to take the chance of partnering with them, especially on their own turf. Then, of course, for socially conscientious companies that want to create manufacturing jobs in the US, moving to China is not an option.
There is some pressure on Congress to provide incentives to support the mining of existing rare earth deposits in the US but the technology to process it still lies with the Chinese. Some are speculating the next resource wars will not be held over oil but rare earth metals.
Rare earth neodymium magnets are critical to the wind industry, including the V-LIM, and while there are plans to reopen Mountain Pass in California for rare earth mining, there is no ready solution in sight despite neodymium being a critical part of all weapons guidance systems and homeland security.
As one of the worst polluters on the planet, knowing the future of green energy, homeland security and the weapons and guidance systems on everytank, fighter jet and aircraft carrier relies on foreign relations with China is a bit scary.
V-LIM update from Portland
Image is everything, so I am told, so Rogue River Wind is working with a couple of firms up in Portland to develop our website and produce educational videos of the LIM and the wind industry in general. This will be done in stages but I invite you to take a look at what each of these firms do and you will know why I am so excited!
The World does a nice write up on the V-LIM wind turbine
Just in case you didn’t see it you can read it here
Mary Geddry, CEO of Coquille-based Rogue River Winds, said the ultra-efficient, low-profile, sturdy wind turbine with a built-in generator called the V-LIM, is generating interest.
She’s gearing up production. But don’t expect any local manufacturing jobs to spin out of it — at least not anytime soon.
“There just isn’t the infrastructure in Coos County at this time,” she said.
After attempts to get the V-LIM off the ground locally failed, Geddry relocated the project to Portland where a prototype was in the works, before she again relocated it to Cottage Grove where it was completed and may be manufactured.
She said some manufacturers in Alaska and the East Coast have expressed interest in producing it, as well.
Federal agencies including the DoD are under heavy pressure to meet 25% of their energy needs from renewable sources.
Driven by new government requirements that call for each military branch to purchase or generate at least 25 percent of the energy they use from renewable sources by 2025, the project is funded by a $4 million federal investment under the 2010 Defense Appropriations bill…
One factor causing concern with wind energy is the belief that traditional wind turbines interfere with radar, hence the interest in a low profile system like the V-LIM.
New Years catch up #2 the V-LIM wind turbine
Rogue River Wind is very proud to announce the successful development of a high bandwidth wind powered generator capable of working in turbulent, gusty wind at all speeds utilizing the increased aerodynamic efficiencies of ducted fan technology. To be specific what we mean by high bandwidth is that unlike typical power curves where the turbine only produces power between 22 and 29mph for example, the LIM turns on at 8mph but more importantly continues to produce power at 80 or 90mph. Since the power output of a turbine is proportional to the cube of the velocity, every time you double the wind speed you get 8 times the power.
We did it. We will be build one more pre production prototype before beginning the full production V-LIM here in Oregon but what is most exciting is the scalability of the generator.
With a few adjustments generators now being purchased with American tax dollars from China could be built right here in the US with much higher efficiencies and providing American jobs. Something to think about with respect to the new $1.4B Oregon Shepherd’s Flat wind farm slated for 2012. While the LIM generator coupled to the standard open bladed wind turbines will not operate at a high bandwidth because open bladed fans simply cannot, the generator can be stacked and perform much better than the Chinese generators based upon 1930′s technology…. AND MADE IN AMERICA!
We will be making some noise about these jobs going offshore when we can build them right here, providing long term family wage jobs in Oregon, in the coming days and weeks. Please watch the news and contact your representatives to keep American tax dollars in the US.
It has been painful, it has been hard, but boy am I a happy camper!
V-LIM Power curves
The first power curves for the V-LIM are done and I will publish them here after some additional verification soon. We have learned a lot from these tests, have changed the magnet topology for a more focused flux and will segment the stator for faster saturation in the production models. Even without these changes we outperform our competitors and after such a long hard struggle, I can’t tell if I am happy or just relieved to be past this point. Am definitely exhausted.
More data soon to come, here and at Rogue River Wind.
V-LIM generator testing, prepping everything
Takes a lot of time to set up the load in order to test this generator. We are winding inductors, ordering resistors, locking the axle down tight to avoid torquing the whole thing across the building and borrowing meters, oscilloscopes and all matter of digital displays…
Where I have been and what I have been doing and why
Coos County and the entire Southern Oregon Coast, without question, is an exquisitely beautiful area, so six years ago I thought this would be a wonderful place to raise my daughters. Within a year, however, some hard realities and culture shocks began to set in.
At first they weren’t so out of the ordinary, I mean everyone knows old people often have too much time on their hands and meddle in other peoples lives, it happens everywhere. The news is riddled with daily accounts of bad cops and incompetent police work around the globe, not just here. The term ‘good old boy’ system wasn’t coined in Coos County and it is no surprise the system thrives here as well as elsewhere.
Elected officials misuse public money and mistreat public employees everywhere, not just in Coos County. Crimes against women are committed everywhere, everyday, not just here. Hard economic times, poor financial planning and lousy business ethics don’t necessarily go hand in hand but they each happen everywhere not just here.
Still there is some other element, some indefinable undercurrent, some unquantifiable but nevertheless measurable resistance, some low amperage buzz always in the background, a niggling impediment to a peaceful and productive life. Coos County has a certain meanness to it. Coos County takes a strange delight in the suffering of others, schadenfreude it is called.
Not that the county and the communities that make it up aren’t changing. Long time incumbents have found themselves replaced with fresh blood, despite an electorate with a below average literacy rate. Some new blood is moving to the area and more importantly some of the old blood, the ‘good old boys’, are grudgingly relinquishing control or passing on. But old habits are hard shaken and the inevitable reaction to fight tooth and nail to maintain power manifests as a mean disregard for anyone perceived as a threat. The despicable handling of the Coos County Road Department layoffs last New Year’s Eve and the recent forced departure of Coos Bay’s city manager are two good examples.
Since moving here I have made some lifelong friendships and had some wonderful adventures but in a nutshell, Coos County is not a good place to raise bright, imaginative and highly gifted children, especially daughters. Despite recent events for which I heap strong praise on local law enforcement for speedy resolutions, Coos County is not a safe or nurturing place for women.
After witnessing the treatment of citizens and employees by local leadership across the county, it isn’t somewhere I want to do business either. In fact, whereas this area made everything harder, set up endless hurdles for me, my children even my damaged veteran son and made almost no effort to support a gift that would have provided $2M in annual revenue for the schools, my little company is now being greeted with an abundance of solid technical support, years of experience and downright goodwill and optimism. A breath of fresh air.
These last several weeks, much to the chagrin of my kids, I have been commuting daily or living in hotels while completing the V-LIM generator outside the strange cosmic influences of Coos County. With a lot of help, we have made less than concentric components concentric, we have laboriously measured and narrowed the gap between magnets and coils. We have remade parts and then remade them again and I have learned the glaring difference between an artisan, an assembly firm and a real manufacturer with years of experience.
We have designed the testing procedure and believe we have located a state of the art digitizing oscilloscope to measure flux fields, resistance, inductance, voltage, amperage and, oh yes, kilowatts output. We now are, I am now ready…
… except to post this I have to find some decent cell coverage or a good internet connection. Guess you can’t have everything.
The V-LIM is making a big splash
This week I filed my patent with the PCT (Patent Cooperation Treaty) through the World Intellectual Property Organization. The USPTO allows an inventor the option of whether to publish the application or not, I chose not to to avoid the IP being exposed as long as possible. The PCT does not afford such an option and the patent is now ‘out there’ for all to see.
The consequence of this is that organizations that monitor new filings have flooded me with inquiries. All to the good but coming at a time when we are fine tuning the generator to spin up and test.
Needless to say, as a new inventor, I am pretty excited.
