Nordic Windpower, maker of a cost-effective two-blade turbine, announced that it's raised an undisclosed amount of interim financing (in preferred stock) to bring its technology to the market within the year. The Berkeley, Calif. company claims that its two-blade turbine design is cheaper, lighter and more effective than the three-blade models most of it rivals rely on.

The round was provided by Goldman Sachs, Impax Asset Management, I2BF Venture Capital and Pulsar Energy Capital. Nordic last raised funds in 2007, pulling in a substantial amount from Goldman Sachs.
