In our continual quest for a "domestic friendly" wind turbine we are experimenting with yet another possible mounting method for the helical savonius....horizontally on the crest of a pitched roof. Provided the roof is orientated perpendicular to the prevailing winds this holds advantages;
1) No mast is required
2) The airflow is accelerated over the crest of the roof
A 20% increase in windspeed results in a 70% increase in power generated!
How did this experiment go? I should like to build one myself if you think there are any advantages, or not if you found disadvantages. Raja
