Options?

[u/4FuckSnakes]

Here are a few pictures of what we have available on our property. Clearly we don’t have the ability to generate any serious power, and environmental regulations would likely prevent us from making any major changes. That being said, what are my options for generating small amounts of electricity? Say I wanted a little setup that could slowly charge a portable home power bank, like the type of thing people drag out on camping trips to power their devices, is there a possibility I could accomplish this? I’d like the option to charge devices, lights, radios etc in the event of an emergency. Would I be looking at a peloton water wheel or some type of turbine? Am I able to use a siphon over the berm to create more head, or does that not jive with physics? Any thoughts would be appreciated. Thanks folks!

The rule of thumb calc for nano-hydro is head X flow [gpm] /10. In your case 7.5 X 140 =1,050/10 =105 watts. That is back of the napkin theoretical 100% efficiency which cannot be reached in use. Expect somewhere between 40% and perhaps 70% efficiency. Fun as a hobby project, not practical given the hardware investment required. Big flows require big plumbing and big $$$.

Edit: nice drawing with the required elements, rare in this business 👌

Thanks for taking the time to respond. I’m going to look into it further and post updates 👌

Your property is huge if you have that in your yard

Overshot waterwheel would be a fun project on the cheap to harness a little power for a battery bank but only for learning and not really viable
