This video series shows step by step the build and installation of a Simple Solar Air Heating Collectors that uses no electricity or batteries made from salvaged materials.The air enters at the center bottom of the collector, where an aluminum baffle spreads the flow across the width of the collector on the glazing side of the screen absorber. The air rises up between the glazing and the absorber, and eventually finds its way through the three layers of screen absorber and flows to the back side of the collector. The air then flows up the back side of the collector to the exit vent located at the top of the collector.
- How to build a Homemade Archimedes Screw Turbine using PVC parts to generate Off the grid Power from a flowing river or stream/creekThis video series shows the setup of a micro hydro system using a flume which is basically a water trough that carries water to some height so the water can fall.The water enters the screw at the top and the weight of the water pushes on the helical flights, allowing the water to fall to the lower level and causing the screw to rotate.This rotational energy can then be extracted by an electrical generator connected to the main shaft of the screw. The materials you need to build this are Four decking boards - To serve as the floor in size to direct the water. Two 2x4’s – These will be cut to provide support for the decking boards,Screws - To secure the boards in place.6” PVC Pipe – Used as the body casing,Flange Bering – To spin the turbine,PVC T-Joint – Serves as the opening to let water flow through it,Farm Auger – This will spin as the water flows through it. Building the flume is a simple process, but it may take a lot of work depending on how far you need to take the water. We will show you how to build one section of the flume. From there, you can replicate this and make the flume as long as you need to. Take your 2x4’s and cut out two pieces that are 22 inches long, two pieces that are 17 inches long, and four pieces that are 8 inches long. Start out by laying the three 22 inch pieces horizontally and place two decking boards on top of them. Take the other two decking boards and use them as the side barriers for the water. Attach the four 8 inch pieces on either side of the supports and use the 17-inch pieces as cross supports over top of the flume. This is the completed section of the flume. Continue to replicate this and add to the flume as needed. You can attach stilts to the bottom of the flume to angle it downwards for the water to flow through it. Building the Archimedes screw turbine is simple. To start, simply take your PVC pipe and attach the pieces together. Since this is only a four-piece setup, it is very straightforward to set up. Insert the auger and make sure it has room to spin without too much friction slowing it down. Once the Archimedes screw turbine is put together, bring it to your flume and you can begin using it. Situate the flume so that it is creating a waterfall that you can position the screw turbine underneath. As water flows into the turbine, it will spin it. You can use this force to generate electricity. One of the great things about this setup is that it never stops. For as long as you have running water in the area, you will be able to generate electricity with this setup.
- How to dig your own Backyard Water Well using a simple shovel.Step by step Video Instructions.This 3 part video series shows the build of a 9ft Shallow Water Well using a shovel and other easily available materials .Considering that most disasters can cause serious disruptions in the water supply and the importance of water for survival, putting in a well is a great idea. Of all the possible sources for water, having a well on your own property is the most secure source you can have.Even so, if the grid goes down, that water could be out of your reach, if you don’t take the right precautions. There’s something that our ancestors all had on their property, which we don’t often have today. No, I’m not referencing a barn, although that would be true. I’m referring to a well.You may be able to augment your home or homestead's water supply for very little cost by digging a shallow well.
