1. Horizontal Axis Fan design

2. HAWTs Vs. VAWTs -HAWTs should be used since it is more effective in producing laminar flow and aerodynamics compared to VAWTs. -It can also keep noise emissions at a lower level even if the size of the wind turbine increases. This shows that in HAWTS, the power output is significantly greater than the total noise from the environment.

3. Parts of a plug and Play Wind turbine It should have similar parts to a plug and play wind turbine because it can create clean electricity at low wind speeds. The interconnection can be charged through batteries. The parts consist of a magnet and a gearless alternator.

4. Airfoil blades When the wind flows over the airfoils, a lift force is generated. When the angle of attack is increased, the lift force and an undesirable drag force also increases. The tangential component of the lift force supports the blade rotation while the drag force opposes it. The wind turbine can improve its performance when the lift to drag force is at its maximum.(Optimum angle of attack)
