Vicky Portwain at the Energy Collective has a post on a vertical axis wind turbine design - Vertical Axis Wind Turbine Market Continues to Expand.
Vertical axis wind turbines appear to be flavour of the year when it comes to small wind turbines. In the UK, supermarket giant Tesco has installed several “Ropatec” vertical axis wind turbines with a rated capacity of 6kW.
The latest vertical axis turbine model to come into the test arena is the new Blackhawk Tilt Rotor Wind Turbine. The turbine is being tested and monitored by researchers from the Blackhawk Project LLC at Idaho’s National Laboratory Center for Advanced Energy Studies (CAES). ...
Blackhawk believes its turbine design distinguishes it from other wind energy systems. The clearest distinction being its blades or ‘airfoils’ that rotate parallel to the ground, unlike many commercial turbines. The airfoils are attached to a tilt rotor in the center of the turbine for which the company has a patent pending.
The TR-10 turbine is part of The Blackhawk Project’s prototype series and is expected to produce approximately 1.5 kilowatts of power which CAES say is “enough electricity to supplement a home, power a workshop or drive other small applications”
Cleantechnica also has a post on an unusual wind turbine design - The New NIMBY-Defeating Wind Turbine.
Ridgeblade is a fabulous wind-turbine solution from UK based The Power Collective. It’s very simple: instead of a large standalone windmill-like structure, put a long bladed turbine along the ridge of a building’s roof.
The blades are about the same length as a medium wind turbine, so you can catch about the same amount of wind. What’s more, as these can be mounted along an existing roof, there’s no need for an additional NIMBY-provoking superstructure.
