Welp... I thought this up independently but I've been beaten to the punch again. [link]
We have a culvert running under a highway which must be four hundred feet long or so.
I want to create a floating Archimedes-screw turbine from lengths of PVC pipe, capped on either end, tethered to each other
by U-joints with a contiguous screw running its entire length.
It won't hurt the fish fry.
It won't damage the ecosystem.
Completely green power generation from an un-utilized source.
(??) Hat's off to this guy.

What's the theoretical power output attainable from a given water flow rate?

Getting trorled about it. |

I looked to see if I had posted this already because I vaguely remember it but could find no evidence so I chalked it up to a Berenstein Bear effect and posted it again. |
|
| |
I know for a fact that, if I did post this in some other reality, I had never seen anyone ever having built one and linking to it making this posting Not-widely-known-to exist and exempt from deletion. |

I rest my case you honour. |

I find for the defendant. [+] |

[+] The U-joints sold me. |

I wonder how much power you'd be able to get from this - there's a discussion of this I saw (linked). Also you'd have to be careful that by slowing down the flow rate you don't cause the culvert to silt up. |

The capped pipe was my first thought for a thin elongated floating tube.
The PVC pipes only come in certain lengths so, to join 400 ft. together while allowing for flexibility, U-joints were also my first thought. |

I hadn't considered slowing the current down but the culvert is from 1955 and is clean as a whistle.
It's tall enough to walk through, hunched-over, and it flows through my property to get there so I can collect anything which might prove problematic before it ever gets to the culvert. |

First link works for me. Not sure why its been flagged twice. |

The only problem I can see is getting ratted out for daring to generate electricity in a completely green and sustainable manner which may effect the bottom line of certain entities bent on hooking and then soaking us for electricity. |

When the winds are a-blowing,
and the creeks are a-flowing, when the rain is so thick that it drowns.
When the sun is a-shining,
when my hens are a-dining, when mother Earth herself makes her rounds. |

All can make power.
All can be stored,
I aim to snag all I can capture.
If I don't start it now,
then please tell me how,
I'm to get my dumb kin through the rapture? |
