Bladeless Wind Turbines: Are They Worth The Hype? - Semprius

A bladeless turbine is not one of the most frequently proposed designs. However, it is simple and made up of only one structural component. So, it has more advantages in terms of manufacture, transportation, storage, and installation. There are no bearings, gears, or other moving parts in the new wind turbine design, so their maintenance is simple.

Vertical-axis wind turbine - Wikipedia

The turbine is a new design, supplied by Wales-based C-FEC (Swansea), and will be operated for a two-year trial. This VAWT incorporates a wind shield which blocks the wind from the advancing blades, and thus requires a wind-direction sensor and a positioning mechanism, as opposed to the "egg-beater" types of VAWTs discussed above.

Best Wind Turbines - Hottest Blade Designs - Kurz Wind Division

Wind turbines come in many shapes and sizes. Wind turbine blade designs are equally varied. Turbines are designed with either a horizontal or a vertical axis. Their blades are flat, rounded, or curved. In generating electricity, a horizontal-axis turbine with a three-blade design is most efficient for energy production.
