This document contains forward looking statements within the meaning of the federal securities laws. All statements in this document that are not clearly historical in nature are forward looking including, but not limited to, any projections of revenue, financial matters, government policies, rules and regulations, environmental impact, development and performance of proposed concentrated solar thermal power plants or related technologies; any statements of the plans, strategies, and objectives of management; and any statements regarding current or future macroeconomic trends or events and the impact of those trends and events on any concentrated solar thermal power plant projects, Solar Trust of America, LLC and Solar Millennium, LLC, and any of their respective affiliates and parent entities. Forward looking statements include statements preceded by, followed by or that include the words “may,” “could,” “would,” “should,” “believe,” “expect,” “anticipate,” “plan,” “estimate,” “target,” “project,” “intend,” or similar expressions. Actual results and developments may be materially different from those expressed or implied by such statements.

11. How troughs work: Solar radiation is concentrated onto an absorber tube situated on the focal line of the trough. The trough is rotated east-west to track the sun. The concentrated solar heat is used to operate a steam turbine to generate electricity. The world’s first commercial scale plants (354 MWs) have been operating in Southern California since 1984.
