    I CANNOT BELIEVE THAT!!

    It is thru that the 35% average efficiency of tri-blades wind turbines is not outstanding. On other hand pretend to produce 3 or 4 time more energy means to transform 105 to 140% of the kinetics energy of wind in electricity, this is just impossible!!!

    By the way, what is the expected noise level at the exit of a jet like turbine?

    I think the 3-4 times more efficient claim is based on the land area needed to produce a given amount of electricity. That is, the generators are more efficient and require a much smaller footprint so you can pack more generators into a given area. So one acre of a flodesign system would produce 3-4 times more electricity than one acre of the conventional three-bladed generators.
