The word 'controller' covers many possible meanings but the 
Morningstar Tristar (and of course the older Trace c-40 with its 
delayed action) is a solar controller that can also be configured as 
a diversion load controller for wind or hydro applications.  I wonder 
if he meant one of these diversion load controllers?  With enough 
load you can also use them for hybrid wind/solar applications.

Last year when I was in Washington state, Ouback did some tests on an 
MPPT wind variant of the MX60 controller but it was a very brief 
truck test of a homebrew turbine and I never heard that they took it 
further.  More like a day out having fun.  Windy boy inverters are 
now quite a commonplace thing but we don't have a product for the 
stand-alone market that optimises the turbine voltage like that. 
Except for the Bergey XL.1 of course and the old Marlec fm 1800.  But 
no third party stuff.  I would be very interested if there were 
something.

No tornados here in Scotland yet.  But plenty of UK Bergey blades 
have hit towers in the past.  I think they made them stiffer at some 
stage?
