2. Solar updraft tower - Wikipedia

   en.wikipedia.org/wiki/Solar_updraft_tower

   Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect. This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity.

3. Nacelle (wind turbine) - Wikipedia

   en.wikipedia.org/wiki/Nacelle_(wind_turbine)

   A notable feature now found on some off-shore wind turbines is a large sturdy helicopter-hoisting platform built on top of the nacelle, capable of supporting service personnel and their tools, winched down to the platform from a helicopter hovering above it. [2]

4. Betz's law - Wikipedia

   en.wikipedia.org/wiki/Betz's_law

   The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).

5. Crosswind kite power - Wikipedia

   en.wikipedia.org/wiki/Crosswind_kite_power

   Crosswind kite power is power derived from airborne wind-energy conversion systems (AWECS, also AWES) or crosswind kite power systems (CWKPS). The kite system is characterized by energy-harvesting parts flying transversely to the direction of the ambient wind, i.e., to crosswind mode; sometimes the entire wing set and tether set are flown in crosswind mode.

6. Small wind turbine - Wikipedia

   en.wikipedia.org/wiki/Small_wind_turbine

   Diagram of a small wind turbine and repeller. A 1 kW micro windmill installed in the suburbs of Lahore, Pakistan. Small wind turbine power output. Small wind turbines, also known as micro wind turbines or urban wind turbines, are wind turbines that generate electricity for small-scale use.

7. Vortex Bladeless - Wikipedia

   en.wikipedia.org/wiki/Vortex_Bladeless

   Vortex Bladeless Ltd. is a Spanish technology startup company that is developing a specific type of wind power generator without rotating blades or lubricants. [1] Power is produced from resonant vibrations when wind passes through the turbine and is deflected into vortices in a process called vortex shedding.
