This is a preview of our new turbine. This turbine is still under development but is performing very well in initial tests.
This turbine is much lighter and faster than previous turbines I’ve built. For one, it is a lift based turbine utilizing symmetrical airfoils rather than a drag based turbine such as the Savonius. This has both advantages and disadvantages. This turbine really goes, but the Savonius starts up easier in super light winds. The airfoils were designed using open source design software and fabricated with composite materials for light weight. This wind turbine also uses sealed bearings and requires no oiling or regular maintenance.

Part 2 is now done and covers power generation: http://www.youtube.com/watch?v=24LSnATIZhw
Harness the wind for less than $100.
DIY vertical wind turbine of the Savonius style.
Notable is that this cost less than $100 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy).
Also, this turns well in a very light wind.
Axle: 3 inch PVC piping from Home Depot
Bearings: 5 inch lazy suzan from Lowes.
Part 2 will cover power generation and connection to the battery bank.
