    Wind energy...the way of the future or a menace ?

    I am wondering...since here we see that 70% efficiency can be reached...why we still cling on to the propellers as a wind energy systems ?Click image for larger version  Name:	vertical-axis-wind-turbine.jpg Views:	0 Size:	85.2 KB ID:	3862358

    1978 McDonnell Aircraft reached 51% efficiency with another H-darreius...called Giromill.

      I just want to inform you if interested that I have solved the problem of the actuators and also tested a two bladed prototype of this 50%+ efficient type machine.

        Roman Bhler also makes these...with more blades.

          Best run at 60% efficiency. 50% better than the HAWT propellers.

            Hi All,
            Is there not a fundamental flaw with all these wind turbines at the moment ? In that all the energy they make cannot be stored and that is why you see some turbines for the most standing still, that being the case should the next move be better and bigger storage capacity designs ?

            Personally I think they are a blot on the landscape especially when not doing the job they are meant to be doing.

            Geoff.
