This project goes over the build of an Archimedes Turbine that can generate off the grid power from a flowing river or creek. This is basically a screw that turns when water passes through the pipe.
You need a 5 foot farming auger to build this. The farming auger is put inside of a 6 inch pipe and placed in the creek at a certain angle, water would pour into the auger and that water would weigh down that auger and turn it. And so as it turned, it would turn a shaft that is attached to the end of the pipe and run a pulley system with a motor to generate electricity.
We take an old belt sander and shave some of the edges to make it smooth and rotate without any friction inside the pipe.
We use an angle grinder to split the pipe down the middle and use the separator nuts to kind of give more space in the pipe. Make sure you don’t split the pipe into two.
Open up enough space on the top by heating the PVC and clamp 2 spacer boards on either side and stretch the opening by using a C clamp.
2 three quarter inch boards are bolted using carriage bolts on either side of the pipe which gives us enough room here to get the auger installed.
Allthreads of size eight and quarter inches are put through the boards and secured in place with the help of some washers and non locking nuts.

- DIY Video:How to build a simple Off Grid Electricity Generation System using Two BatteriesThis project shows you how to generate Off grid AC Power using a simple Solar power station with 2 batteries.This system can provide enough off the grid power to run your appliances around the house.You can easily run light,a laptop computer, small tv and fan for several hours. Most of the item required can be bought from your local store or Amazon.The rough cost of building this system is as follows : $150 for 100W Solar Panel $75 each for 2 batteries. $20 for 400w Inverter $40 for charge controller. The whole system comprises of four things, a couple of batteries, inverter, and a charge controller.The inverter is purchased from Harbor freight ,the charge controller from fry electronics.The deep cycle batteries are from Walmart. So you start by setting up your panels outside. In this case, I have six one amp panel set up, 15 watts a panel, so that's 90 watts coming in. I lead them straight down to the main connection, it's just the six black wires all connected together and twisted tightly to that extension cord wire and the six red ones connected.Feed the line into your house,goes straight to the charge controller. The output wire from the charge controller goes into the battery.So solar panels to charge controller ,charge controller to lead battery in your bank.And as you want to expand this to two,three or more batteries, just use some automotive cables and go from positive terminal of one the positive of the other. And with a black wire, negative terminal to negative terminal, the other one. When you want to run something, just get your inverter that converts the power from DC to AC, take the clamps, clamp them onto that same lead battery in the system. So again, red to the positive side, black to the negative side and flip it on. So remember, when you hook things up like an inverter, or the charge controller or voltmeter, anything you're going to hook up on here, make sure you always pick one of the batteries to be the lead battery and hook everything to that. Whether you parallel one extra battery with it, or five or six or however many you want to put on there. Also added here is a lighted voltmeter which gives you a constant reading on your battery bank so you know exactly what's going on with it at all time. https://www.youtube.com/watch?v=cgEvCLJuBkg https://www.youtube.com/watch?v=8LAjx_XAR90 A simple system that can come really handy during a power outage or in any emergency situation.
