  • Ausra utilizes quite inexpensive 40-foot-long flat plate mirrors known as Fresnel reflectors to focus the sun's rays directly on the water pipes and thus boiling the water to run the steam turbines, which will then generate electricity. solar power plants use structures with curved mirrors to focus sunlight onto tubes of oil.
