</b>Imagine the water running in the maze of pipelines buried under
your feet as you cross the street powering the electrons supplying
light to your house.</font></div>
<div><font face="Arial"><br>
Two Western U.S. cities are aspiring to do just that with experimental
technology designed to harness the energy from water flowing through
municipal pipelines to power up homes.</font></div>
<div><font face="Arial"><br></font></div>
<div><font face="Arial">Lucid Energy is behind a project in Portland,
Ore., that will generate about 1,100 megawatts of electricity --
enough to feed about 150 homes in Portland.</font></div>
<div><font face="Arial"><br></font></div>
<div><font face="Arial">"It's low-cost baseload environmental
electricity" addressing a "nexus of energy," Semler
said, where water and energy meet in a push-and-pull kind of
relationship.</font></div>
<div><font face="Arial"><br></font></div>
<div><font face="Arial">Whether the gamble pays off is also in the
distant future, with the project's possible expansion somewhat hanging
on Rocky Mountain Power's buying prowess.</font></div>
<div><font face="Arial"><br>
"It's free power," Pearson said. "[As] technology
progresses, who knows, maybe we'll be able to generate more power like
this in the future."</font></div>

justify trying to cope with what may be intractable problems? The very
nature of the question belies its origins in the assumption of science
that one has to believe that all problems are solvable."<br>

" 'Triage' is a dirty word in some conservation circles, but like
many dirty words, it describes something common. Whether they admit it
or not, conservationists have long had to make decisions about what to
save.<br>
<br>
"As more and more admit it, open discussion about how the
decisions are best made -- by concentrating on particular species, or
particular places, or absolute costs, or any other criterion --
becomes possible. Whichever criteria come into play, one thing remains
constant. The decisions have to be made quickly."<br>
