on the roofs of homes. Do an experiment and see if you think this is a
good idea. Can you design a shroud around the turbine to collect more
wind? Some inventors think this might be a good idea. What do you
think?
Wind park effect
Each wind turbine extracts some energy from the wind, so winds directly
downwind of a turbine are slower and more turbulent. For this reason,
wind turbines in a wind farm are typically placed 3–5 rotor diameters
apart perpendicular to the prevailing wind and 5–10 rotor diameters
apart parallel to the prevailing wind. Energy loss due to the “wind park
effect” may be 2–5%.
What effect do you find when you move the turbines around in your
MINI wind farm? Place a few turbines very close together, or right behind
each other. Do you notice a reduction in the efficiency of your wind
farm?

This wind farm was designed to minimize
