Extrinsic hemolytic anemia is also known as autoimmune hemolytic anemia. This type of anemia develops when the spleen traps and destroys healthy red blood cells. Intrinsic hemolytic anemia develops when the red blood cells produced by your body are defective.

Today, the windmill's modern equivalent-a wind turbine-can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.
Chapter 16: Wind Energy. Wind can be used to do work. The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy. When a boat lifts a sail, it is using wind energy to push it through the water. This is one form of work. Farmers have been using wind energy for many years to pump water from wells using windmills like the one on the right.
