  • can i connect a motor to it and use it as a wind-turbine?

  • @skozzy1968 I bought one two days ago installed it today and it is spit out hot air like crazy!

  • John Breeze.....Really?

  • I purchased to from Bunnings at $59 each. to all who ask, no power is required and on a still day it spins because the heat is being forced out the ventalators and therefore it spins and creates draw and spins more and then more draw. I have one mounted directly above my loungeroom and bedrrom and cant hear a thing.  Tp product.

  • @vincevega0

    None, either the wind from any direction or hot air rising from the inside makes it spin.

  • How much electricity is required to spin it?

  • Where can you buy one of those?

  • GAF roof mount power ventilator on a thermostat is a much better option.

  • Lomanco Turbines are better!!!! jackass

  • Very interesting, I always thought those things worked with some kind of motor, who knew...
