	Parabolic troughs, one of which is shown here, have been around for 25 years, and the technology will be around for at least another 25.
<P>Parabolic troughs reflect sunlight to heat liquid carried through a tube above the troughs. That liquid is converted to steam, which drives a traditional electricity turbine.

One solar thermal power plant developer filed for bankruptcy in the early 1990s. But the technology is making a serious comeback. Building a solar plant in Arizona is cost-effective compared with a natural gas plant, said David Jallo, project head for the 280-megawatt Solana project at Arizona Public Service. At a recent <NEWS:LINK _moz-userdefined="" url="http://www.ceres.org/NETCOMMUNITY/Page.aspx?pid=661">Ceres conference</NEWS:LINK>, Jallo attributed this to solar costs going down, while costs of natural gas plants are going up.

These concentrating solar power plants are best suited for desert areas, like the southwestern U.S. and parts of Spain.</p> </DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/AAC6CE8D-7BF9-4AE7-8AF7-48324DEB3CCC/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
