Today’s delivery included two tiny hydro turbines! I quickly rushed out on my lunch hour to purchase some adapter hardware and give them a squirt.
To my amazement, after hooking it to my common variety garden hose and cranking up the water pressure, it delivered a full 12V. Actually up to 12.55V. Amperage was very close to the advertised 220mAh.
Before getting to excited this was all under no load and ran for maybe 2-3 minutes before it started to rain for real and I returned inside.
Just having done this tiny experiment gives some new project ideas for the future:
- Nano hydro turbine powered garden sprinkler flashlight – water your lawn or garden at night without power cords or batteries
- Nano hydro turbine powered lawn sprinkler w/colored lights – water your lawn at night. The water drops will reflect the colored light from the LEDs making for enjoyable visual experience.
I am considering ordering the 80V nano hydro turbine and giving that a try too. The unit is the same size so I am postulating that it doesn’t have the voltage limiting circuit included the 12V and 5V models.
My larger goal is to hook say 4 – 6 of these is parallel up to my rain gutter in an attempt to see how much power I can harvest during a good storm using the nano hydro turbine. Check out my DIY Nano Hydro Turbine project.
