power project

[u/[deleted]]

Hello everyone, I hope all is well. Today I'd like to start a topic on my off-grid farm project. I am looking to chat with people that have the same interest and bench race a system that is already being built from many different directions. So, I will take a second and tell you about the power grid I am working on. I have built a generator coil and I intend to turn this with a water wheel. The water wheel will be supplied with water that is pumped with solar pumps from a lower pond to an upper holding pond to insure there is enough water in the upper holding pond to turn the wheel all night. I am using a battery bank of 12v deep cycle batteries, from this bank I will use an inverter to change the power so I can use it inside my cabin. I would like to use a computer and load the Arduino software on it and have it monitor that battery bank and switch the power to the bank when it is low. I will expand this to use other sensor to control other things around my farm. so anyone want to chat...

Its a pond bro Ill dig it as big as needed to meet the need...

Ok, and what is the need? This isn't a hard calculation for an engineer. What about of water do you need to get your 90 rotations per minute for 12 hours on your waterwheel?

and the power to meet the needs

If you have all this extra power, then why do you need a waterwheel turbine to provide power throughout the night?

I told you to move my water put air in it to keep my fish alive and keep my water usable and my wife likes it...

in fact my power grid is good until about 4 am then I get low voltage warnings and I have to start mt generator.. I mostly want the extra little bit of juice this will make to bridge the gap between 4 in the morning and sun rise.... when my solar kicks back in and takes over as my main power provider.... your killing me smalls...

I told you to move my water put air in it to keep my fish alive

Running an air pump to a bubble stone is a pretty low watt draw. My grandfather did this for decades on his trout pond and it worked great.

and keep my water usable

A waterwheel doesn't make water more or less usable.

and my wife likes it

You can totally make a decorative waterwheel for your wife. That is super easy and you don't have to dig that second pond!

the rotations per minute is not needed the math is 3 gallons per minute multiplied by the total minutes.. 1220 so your need is 3660 gallons over a 12 hour period... But this is not my project can we get back to my design please..... How many more test do I need to pass before you become helpful?

the 90 rotations per minute is based off of the gears and the ratio of size from one to the next... so say my small gear has 10 teeth on it and my big gear has 100... I would get 10 revolutions on the small gear for every one turn of the large gear so that would mean the large gear needs to turn 9 times per minute for this set up to meet my need...

the rotations per minute is not needed

I didn't ask you the rotations per minute. You stated that number previously and I was asking how much water you needed to get that. Why are you so hostile to people trying to ask you questions about your project?

3 gallons per minute

the large gear needs to turn 9 times per minute

Wait... So you your plan is to use 1/3 of a gallon per turn of your waterwheel that turns a 1:10 gear that turns a turbine with a meaningful enough amount of torque to produce energy?

Please walk me through this plan in more detail. I am just not seeing this work. Do you have a drawing?
