 +Usable power typically starts around 10mph, where flags stand straight out.  Full rating is typically achieved at 20mph+, where small trees sway and whitecaps appear on bodies of water. 
  
 Generally speaking, windgens with higher max outputs have higher minimum "start-up speeds", or speeds when the vanes start turning.  Vandwellers in normal wind conditions will likely bias toward low start-up speeds, resulting in relatively low max outputs.   Generally speaking, windgens with higher max outputs have higher minimum "start-up speeds", or speeds when the vanes start turning.  Vandwellers in normal wind conditions will likely bias toward low start-up speeds, resulting in relatively low max outputs.  
  
-A rule of thumb for wind power is that flags need to be flying straight out before you can make usable power.((the rule of thumb for solar is you need to see well-defined shadows on the ground)).
