Gigantic 10 MW Turbine Bends Design to Scale

As Europe forges ahead with larger and larger wind turbine sizes for off-shore wind, a design change may now be required. The incentive to build larger turbines is that when you increase the size of the turbines you decrease your costs per megawatt significantly.

Another is that the best wind resources, the ones with no environmental controversy are further off-shore, in deeper water. As European countries venture further offshore in search of the best wind farm locations, the size of the turbines goes up as the water gets deeper.

But a proposed new 10MW turbine built by Norwegian turbine developer Sway would be as high as a 30 story building above the sea, 533 feet tall with 476 foot blades. This is so much larger than the 5 MW turbines that were even recently on the cutting edge of turbine design, that an entirely new kind of foundation design may be needed.

Instead of fixing the turbine to the sea floor – the turbine that Sway has been developing since 2004 allows an enormous, lightweight turbine to sway around a fixed base and to even swivel on it to create energy as wind direction changes. There are many designs for floating turbines. Like them, this idea will take a smaller scale model to test its effectiveness.

But that “small” test turbine size will itself be twice the size of most US wind farms with 2.5 MW turbines. Just the test will require a 5 MW turbine! (more…)

Czech Republic Revitalizing Brownfields with Solar
Yesterday Conergy announced that it is building its second megawatt-class solar park in the Czeck Republic. This solar plant is being built on a brownfield site – one that used to be a pig farm. The 1.48-MW solar power plant is being built near Velký Týnec, about 80 km to the north-east of the Czech Republic’s second-largest city Brno.

Colleges Investing Heavily in Solar
Sustainability is an important selling point for colleges and universities. Students are not only demanding educational programs around renewable energy, they’re encouraging their own institutions to “walk the walk,” and install systems on campus.
