Just wonder what a 'ruff' est. is to install a small turbine to power my homestead.

Hi Shimmy,
Rough estimates for small wind tend to run anywhere from $5,000 - $40,000 range depending on several factors including:
-The amount of electricity your home demands
This is the biggest opportunity to save on the cost of your system. Reduce your energy demand and reduce the cost of your system.
-The size turbine you choose
-Tower height

Please don't quote me.
We are setting up an oversea facility to build Rotor using our new technology (early next year).
We anticipate a DIY kit ranges about $1500.00 enough power to furnish a 3000 square foot house.
