Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind’s energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind’s force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.

Currently on the market there are many shops and stores selling cheap LED and solar lights, especially small retailers selling online. Many customers want to save investment costs, so they bought many poor quality lamps after only a period of use from 6 months to 1 year.

When calling the lamp seller for warranty, they could not be contacted, but the previous sales unit or contactable product did not have a name or label or warranty period stamp on the product, so these stores have since denied the warranty of lamps sold before, this has caused a lot of frustration for many consumers in recent times.
