    if you look, it looks like a play on this

    they've been doing some very clever stuff in conventional 3 axis wind turbines.

    lets stay with that

      this article and some more updates on it including prices ign another post coming soon patbahn.

      I'm mostly packing this week for our move to Florida, and did not expect to post at all this week, but I found a few minutes to rest for bit before another run to the dump.

        someone as well informed as you are on the climate crisis is still willing to move to FL, a big sandbar much of which is liable to be under water if we lose.

        IMO, as extreme weather disasters pass a tipping point of non-deniability, maybe in the next year or so if there is a major El Nino, public opinion will undergo a phase change, as for secondhand smoke in the 90's and same sex marriage currently.

        In that case, there is still the technical and economic capability to ramp down fossil folly short of the point of no return, at which runaway positive feedbacks would kick in.  

        When people like Buffett invest heavily in renewables, a lot of other big players pay attention.

        There's no such thing as a free market!

      interesting to hear from engineers like yourself and also compare prices, and get the idea out that getting silent turbines to open up residential wind could be a big frigging deal.

      Also this design was original used for underwater use, so I'm thinking this may explain its curious shape.

      The authors argue that by using composites they are able to reduce the weight of the "blades" providing efficiency advantages, however, I have not studied the details.

      Maybe you've solved the mystery for why it seems to have disappeared.

      •  this may be quieter as the Archimedes is (0+ / 0-)

        but, i doubt the solidity factors or hub to tip ratio is very good.

        it probably disappeared because it's a bad idea, or very very very niche or impossible to build cheaply,

        personally i think extraordinary cliams require proof.

        We are doing amazing things in simple horizontal 3 blade wind turbines.  that's now the standard to measure
        everything else.
