I like how you installed a barrel in your system to slow the water down enough to let the grit fall out of the stream. For this bigger system, it might have to be a huge tank to allow separation.

These 100 gallon plus systems would need a lot more holding tank to slow down the water.

I ordered my screen and poured a concrete box to mount it at the appropriate angle. My coanda box/ screen is 2x2. That alone saved me about 6k in my hydro build.

Hey, I will be happy if you can show their turbine in action and the amount of power it's producing. I love hydro power a lot!!

I sure will! This is a 4 part mini series and then a full length video on the full system.

I pull about 90 GPM into my 3" line with my Coanda screen intake. BUT, later in the summer it gets algae or some kind of growth on it that requires me to pull the screen and lightly sandblast it off. It's also on the small side for my needs, and I plan to replace it this fall with some galvanized steel perforated sheeting that I came across at a salvage yard. It has 1/8" diameter perforations, and configured properly should be able to pass more water, we shall see. I produce 850 watts back into the grid for most of the spring, summer, and early fall.

I don’t understand why y’all aren’t building the reservoirs out of stone. There’s so much of it! Make it make sense!

Why not work with the pipes above that are feeding that creek? That looks like a good foot or two of additional height.

@Mywhtjp Жыл бұрын

I agree. For a $100 in concrete to build a bigger head and use all of that water flow would before free power\more efficient.

They wanted to get the coanda away from the road a little for asthmatic reasons. I did not show the off grid cabin but it is very nice.

The 1 foot would have added 10w.

How many liters in there?

@tdadyslexia Жыл бұрын

The channel could do with be cleaned out, there's a lot of silt build-up, behind the intake.

What’s the purpose of that overflow tube in the dam wall?

@andrewallason4530 10 ай бұрын

Looks like it was the owner’s original attempt to create a water collection input you can see in a few shots the long slot cut inside the weir, which I assume was covered in fine mesh, in the hopes of a cheap water source. It doesn’t work.

Hey Seth.. I just wrote them an email asking a couple of questions. How small is too small for a micro hydro system. I have a year round Source of water but it's about 2 to 4 gallons a minute.. There is a second source with a valve on it that is closed. Both sources come from the same ditch. I guess I will experiment after opening the 2nd one to estimate a total gallons per minute when I get home.

@LandtoHouse Жыл бұрын

The basic hydro calculation is: (Head in feet X GPM)/10=power So let's say you have 50 feet of drop. (50 X 4)/10=20w. You can see thatcis not worth the effort. My personal system has 150 feet of drop with 15 to 30 gpm flow. So I can get 100w up to 450w.

@@LandtoHouse Thanx for the reply. Guess I'll stick to my solar and wind projects. This ditch is almost level.. I do refer to the place as the swamp.
