  1. I don't think it's asymmetrical. It just looks asymmetrical because of perspective in some of these animations.

  2. The blades for new offshore wind turbines are already in excess of 130 m long (which makes the diameter 260 m which is already more than for this proposed turbine type). Also, these very big blades are easier for offshore projects because ships transporting the components can be made very big. It's also possible that if this thing ever becomes reality, the first commercial units could be smaller and only grow gradually in size.

  3.  @angellestat2730  My understanding is that this rattling is the main reason why most (though not all) wind turbines use 3 blades (rather than 2).

  4.  @occamraiser  The point was that in this video the two ends of the blade look different from each other. However, I think that apparent asymmetry is just an illusion due perspective.

  5.  @mnomadvfx  I don't think it's asymmetric at all.

  6. "Define "one"!" I think the point is that it's manufactured as a single piece (even if in function it doesn't differ much from a turbine with two blades).

  7. I think it's symmetric.

  8. You can easily just skip over the sponsor section.

  9.  @23desdfe345r2fd23f23  At least Mingyang Wind Power MySE 16.0-260 has a radius of 130 m. I think it's still in prototype stage but that's still farther than the turbine concept in this video.

  10. It's because the blades move quite fast through the air. Faster means that thinner blades are optimal. Bigger blades would increase drag.

  11. What does your question even mean? The unit here is MW, not MWh.

  12.  @charleswillcock3235  Where does that figure come from? I re-watched this video I didn't notice that figure.

  13. It shouldn't be any different than for the kind of offshore wind turbines that are use in today.

  14. Offshore wind is already a thing. This thing can use the same kind of transmission lines as existing offshore wind projects.

  15. Natural gas is more of a complement than a competitor. Electricity from natural gas can be adjusted to compensate for the variable output of wind and solar.

  16.  @angellestat2730  What about changes in wind direction. Most wind turbines have 3 blades because if the turbine has to yaw while rotating having only 2 blades will rattle the turbine (whereas 3 or more will just just cause a steady bending force).

  17.  @angellestat2730  I think you misunderstood. The issue is that a rotating turbine is a gyroscope. Think of a normal wind turbine. If the wind changes direction, it has to yaw to face the wind (as a wind from the side wouldn't be useful). If the turbine is rotating and yawing at the same time, the gyroscopic effect will twist the turbine either up or down depending on the direction if it has 3 (or more) blades. If it has only 2 blades, the same thing happens except the strength of the gyroscopic effect varies. It's strongest when the blades are in vertical position and the weakest when they're in the horizontal position. This varying gyroscopic effect rattles the tower can causes it to wear out faster than otherwise.

  18. "why said to be asymmetrical" I don't think it was said to be asymmetrical. I think it only looks asymmetrical in some of these animations because of perspective.

  19. No.
