@mwt I think the main issue would be lack of height... The main driver in a hydropower system besides flow rate is the height of the water column. But there are a lot of cool systems around if you search for "pico hydro", though they are geography-specific, often in rural valleys. And you need to a run a long pipe up a hill usually. But they're awesome when they work because even if it's "low-power" compared to say a solar panel, it's often 24/7 so you can harvest a lot of energy with a small turbine. There is also this small project recently funded in the EU: https://lauds.eu/open-calls/2/democratizing-energy-through-diy-renewable-energy-solutions/flow-optimized-water-energy-recovery-flower They're trying to recover energy from mains water systems.
