This means it has to built in a secured building with 24Hr surveillance which cost a lot of money. Then they'll need a bypass to be able to remove the spool to replace parts. Those parts are going to be exclusive with a high price tag.

2 million dollars for 20 years, that's not a lot of savings.

and thats not counting if anything need repair or regular maintenance....
now its a good concept for personal use on a smaller basis if you wanted to tap a river, creek or spring up a mountain to generate electric out in the sticks...

If they had to pump that water to a tank, they loose energy from that POS. Why don't engineers who think this stuff up not understand this crap. ENERGY isn't free. Unless it comes from a nuclear reactor.

this is probably a better idea than the useless wind towers.

Why don't the internet mouths who criticize this stuff not understand you have to read the whole article?







You clearly need to read more thoroughly.





"The turbines can only be installed in places where municipal water pipes flow downhill, as using electricity to pump water through them would defeat the purpose."

2 million dollars may not be "a lot" but it's another 2 million they didn't have before.


You can fix a lot of potholes with 2 million.

The four turbines are expected to produce at least $2 million worth of free electricity over the next 20 years. More turbines would produce more.




it probably cost double to put those turbines in and add in maintenance they saved nothing but it cost more..

Here's another article with a better explanation:


https://www.good.is/money/portland-p...-turbine-power


Once fully operational, the installation is expected to generate $2,000,000 worth of renewable energy capacity over twenty years, based on “an average of 1,100 megawatt hours of energy per year, enough electricity to power up to 150 homes." The money generated will be split among the project’s investors, as well as will be used to recoup the cost of construction, and ongoing upkeep of the system. After 20 years the Portland Water Bureau will have the right to own the entire project and all subsequent energy and profit generated by it.




It looks like the cost is not public and it wasn't paid for by the city either, it was paid for by a group of private investors. That tells me that people who have lots of money and invest for a living think it will be quite profitable and the city has no financial risk here if it doesn't work well.


Sounds like a good deal for the city to me.
