Have your generators ever been used with the Savonius or Darrieus models of ( vertical axis) wind turbine?
The two types of vertical turbine you mention are normally used for smaller applications. Q: We were asked a few days ago if our PMG would work with a Forgen (vertical axis) turbine. A: We will be addressing this in the near future and will almost certainly develop a smaller PMG which should lend itself better to this sort of application.
