I think it's interesting that the head of Clipper Windpower (Jim Dehlsen) was instrumental in the evolving technology of wind power, bringing a technology virtually from the stone age to what we know today, in the process making what once was a forbiddingly expensive form of alternative energy and reducing its costs from 80 cents per kwH (in today' s currency) to around 5 cents today. Without that technological improvement, wind power simply would not be feasible, even with today's high energy fuel costs. General Electric got its start in the wind power business by buying the technology of Dehlsen's earlier
turbine designs. One of Dehlsen's biggest
successes was in redesigning the bearings to
acheive a more maintenence free and longer lasting turbine. He also introduced blade feathering technology to optimize energy extraction from the winds. He'll go down as the
father of American wind power.

Whose responsibility is it to upgrade the feeder lines?

This is big, really big. Once the big oil companies start moving in, we should see much needed muscle behind wind power, which has been hampered in the past by a sort of "Do it yourself" kind of mentality and lack of resources (or common sense) to supply sufficient infrastructure, as has occurred in Minnesota , where wind towers are being paid not to operate because the utilities haven't sufficient capacities in their feeder lines. Texas, however, is doing things properly, having identified the sections of the state with the greatest wind resources and begun constructing power paths to those areas.
Texas should serve as a model to other states
planning on tapping large wind resources.

The feedback thus-far is interesting; the news is the commercial alliance between 'one-of-us' and an Oil Major Multinational, and the discussion is almost all about manufacturing & supply logistics and regional interests within a single country.

The fact is that this sort of contract will be the driver for big R&D budgets and market development - it's big, AND it is international.

Those wind turbines look extremely inadequate for the purpose for which they were constructed. Maybe a redesign and open competition for construction is needed. As long as there is a monopoly on wind energy controled by GE there will be a failure to adequately harness the wind energy properly and adequately.

"Why aren't these turbines being built in New York, Texas, and South Dakota, instead of Iowa? "
Shipping a turbine is not difficult or very expensive considering its overall cost - a single railroad car can handle several of them and makes it pretty cheap to ship them. Tractor
trailers haul the units the last miles and are,
per mile, more expensive, but there's no reason to assume that that leg of the journey would be
shorter just because you have an assembly plant in the state. Regardless, any conceivable transport savings would be microscopic compared to the costs involved in building a new factory that would have a limited lifespan. The costs of simply planning a new factory would overwhelm any conceivable transport savings. The center of the country is where most of the wind is, so
locality of production would favor Iowa, anyway,
even though it isn't a major siting factor.

Why aren't these turbines being built in New York, Texas, and South Dakota, instead of Iowa? This is not a rhetorical question-- I am curious. With all the proposed NY and Northeast turbine projects and competition for the turbines, why has no one has attempted to manufacture them closer to the projects? transportation is always an issue.

The Generator technology is new - Permanent magnet type - for MW Class Wind Turbines. It is claimed that it would have more advantageous and that the problems in DFIG design would be eliminated. DFIG type itself is recent and is preferred by many leading manfacturers. Is there a comparative evaluation ?

What is the reason for neglect of the sub-MW Class of Wind Turbines ?
