Extracts from the Lucid Energy FAQ [0] ....<p>How does the system work?<p>The LucidPipe™ Power System uses the flow of water inside the PWB pipeline to spin four 42” turbines that produce electricity for PGE [Portland General Electric]. PGE purchases the electricity from Conduit 3 as part of their strong commitment to both renewables and local sources of energy.<p>How much energy will the project generate?<p>This is a 200 kW nameplate capacity project. The system is expected to generate an average of 1,100 megawatt hours of energy per year, enough electricity to power up to 150 homes.<p>...<p>DOE Grant – The U.S. Department of Energy awarded Lucid Energy a phase 1 SBIR grant to field test the LucidPipe technology.<p>Investors – Lucid Energy has secured private funding from a very active syndicate of investors including Northwest Pipe Company, the Israeli hybrid venture capital&#x2F;crowdsourcing platform OurCrowd, Star Energy and the Harbourton Fund as well as more than $1 million from the U.S. Department of Energy. The funding is being used to accelerate commercialization of the LucidPipe Power System worldwide<p>-----<p>Notably absent is what percentage of the power revenue Portland gets from the energy generated.<p>[0] <a href="http:&#x2F;&#x2F;www.lucidenergy.com&#x2F;wp-content&#x2F;uploads&#x2F;2015&#x2F;01&#x2F;Lucid-Energy-PDX-Fact-Sheet_20-Jan-2015.pdf" rel="nofollow">http:&#x2F;&#x2F;www.lucidenergy.com&#x2F;wp-content&#x2F;uploads&#x2F;2015&#x2F;01&#x2F;Lucid-...</a>

For those interested in more details on this project, PBS Newshour had a good report on it in April <a href="https:&#x2F;&#x2F;youtu.be&#x2F;vlbp0VxZG28" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;vlbp0VxZG28</a>

I&#x27;ve never understood the concept of something like this. Isn&#x27;t the energy generated canceled out with power expended to pump it through? I feel like friction would never make something like this useful.<p>Can someone explain how this kind of generation is beneficial?

Salt Lake City is planning a similar project to harness energy from municipal water pipes. From 6 months ago:<p><a href="https:&#x2F;&#x2F;www.ksl.com&#x2F;?sid=35603966&amp;nid=148" rel="nofollow">https:&#x2F;&#x2F;www.ksl.com&#x2F;?sid=35603966&amp;nid=148</a>

I&#x27;ve often wondered why someone couldn&#x27;t invent a home irrigation system that was recharged by the flow&#x2F;pressure of water passing through.

I hope that this will help lower the insanely high utility bills that Portland residents have to pay.
