Build Your Own Hydroelectric Dam [Hackaday]

View Article on Hackaday

We have to admit that we often think about building unusual things, but we hadn’t really considered building our own hydroelectric dam before. [Mini Construction] did, apparently, and there’s a timelapse of the build in the video below.

We wished this was more of a how-to video, although if you are handy with brickwork, the mechanical construction seems straightforward. Presumably, you’d need to understand how much force the water had but we don’t know if there was math involved or just seat-of-the-pants design.

We were unclear what the tower was for until we saw the turbine installed in it. We weren’t clear where it came from, and it looked like maybe it was repurposed from something else. If you recognize what it is, or have a guess, drop a comment, will you? While the brickwork was impressive, the wiring — especially near water — looked a bit suspect. We hope that was just test wiring and a more permanent arrangement was made later.

We have seen hacker hydroelectric before, but rarely. Waterwheels seem much more common. Honestly, the masonry work was the best we’ve seen since [Walt] built a bomb shelter.
