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 Battery Backup Power Station for Emergency PowerThis project goes over the setup of a simple battery bank for your offgrid applications. We use three AGM batteries, and they're about 245 amp hours each.Marine or deep cycle batteries also work. Dont get a car battery.Make sure that the batteries are about same age or they start bringing each other down. The wires are connected through the positive ports and negative ports of each batteries. The positive from the inverter is connected to the positive of the first battery .Negative from the inverter is connected to the negative of the 3rd battery. The battery chargers are from Pros Series DSR.It ramps up the optimum charging voltage. https://www.youtube.com/watch?v=Zxvo3t898xI
- DIY Video : How to build a Survival Water Distillation System for under $5 and turn Salt Water Into Fresh WaterThis project goes into the build a simple survival water distillation system to turn your salt water into drinkable fresh water. This setup can be made with little more than two glass bottles, some metal trays and some sand. So the primary components of this setup are two glass bottles, the wider the bottles are in diameter ,the better and a pair of metal trays. The first part of this process will be to prepare an area such that the two bottles can rest mouth to mouth. The important part is that one of them needs to be suspended over a heat source. This could be done over an open campfire, you just need to find a way to suspend the bottle above the flame either using rocks or logs. Cut a small notch on one side of the pan so that the neck of the bottles can sit a little lower in the pan. This is by no means necessary, but it will make the setup a little more secure. With the trays secured in place, both of them are now filled with sand. The sand will allow the trays to more efficiently act as heat sinks, one tray to cool one of the bottles and the other tray will be used to very evenly heat the other bottle so that it doesn't shatter from being heated too much on one side. The bottle is pressed firmly into the sand so that it gets good thermal contact and will be heated evenly. The second bottle is adjusted such that its mouth will meet up with the first and it is also pressed into the sand to obtain good thermal contact. Another reason that I'm using sand for this is because it makes it very easy to adjust the bottles angles and it is best to make the bottles meet up as evenly as possible so that there is not much room for water vapor to escape. We want it all to make it into this second bottle where it can condense as freshwater. As an additional measure to keep the cold half of the bottle cold, we wet the sand on this bottle with water or cover them with a wet cloth to allow evaporative cooling to take place. With such a large quantity of sand in this tray it does take a little while for it to reach the boiling point and get this process started. But once the sand has reached that point, it stays hot for a long time. So it is a pretty quick process as the water boils dry in this first bottle to simply refill it and you can continue on with the distillation process as long as you want. Rotate the bottle so that the top portion becomes hot from the steam, it is rotated into the cold sand below. And in that way the entire bottle maintains a cold temperature which causes the distillation to go much faster. https://www.youtube.com/watch?v=R_-wFiFdwAE
