If Portland can install these water pipes to generate energy 24/7, in any type of weather, and is environmental friendly, then we need to use the same technology here in Puna, Hawaii. Our water pipes on the island are old, and need replacing, which is why it makes even more sense to bring this technology here to Hawaii.
This would also end our need for Geothermal energy. which uses so much of our water for it's drilling. [

Lucid Energyportlands-new-pipes, a Portland-based energy company, has come up with a brilliant idea to harness electricity from the water that flows through a city’s pipes. Small turbines are installed into the pipes which send the energy collected from the flowing water into a power generator.
“It’s pretty rare to find a new source of energy where there’s no environmental impact. But this is inside a pipe, so no fish or endangered species are impacted. That’s what’s exciting,” Gregg Semler, CEO of Lucid Energy, said in a statement.

What an amazing idea. Truly we live in miraculous times.

The first law of thermodynamics states that energy can neither be created nor destroyed, just transformed from one form to another. So where is the alleged free energy coming from?

Hydro electric works where you have a water source at a higher elevation ( potential energy ).

Generally works best where the flow rate is high and the water is free.
Not much potential energy from an underground well, and catchment water has neither the flow nor consistency to be worthwhile.
What would be cost effective is to install some huge windmills offshore up Hamakua way, near where certain geothermal proponents live.

This page link shows how it works and the turbines in action. Water flows through LucidPipe’s lift-based turbine, generating power as the turbine spins. The hydrodynamic turbine has been carefully designed and lab tested to maximize efficiency and power generation while limiting the onset of cavitation. As velocities increase, power production increases. Due to the lift-based design of the LucidPipe turbine, the system generates power across a very wide range of velocities. [

So you think your catchment can power that ?

They just took vertical wind turbines and stuck them in flowing water. Each turbine will convert gravitational linear motion into rotational motion, meaning the flow slows down for each one. With them spaced that closely, the third one is not going to be spinning as fast, and you are going to be cussing at the lack of water pressure at your house (this system is being proposed for county water mains). As a dedicated system, with some large flash rain reservoir uphill, the feed head at the bottom, will produce fairly steady power if there are enough rains to keep the reservoir filled.

Hmm, burn lots of oil to pressurize water pipes, then use these to ruin the water pressure and get a fraction of the energy back.

Windmills are a great idea, except that they provide less than 1% of required energy and kill birds. Solar is the only semi-reliable source of green energy.
