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.
- How to build an Off grid Rocket Mass Stove Hot Water heater using Copper Coils, Clay ,Sand. Also works as a cooktop!!!This project goes into the build of an off grid rocket mass heater for heating water without propane or electricity. This system also doubles as a cooktop. This rocket stove is really efficient and can create tremendous amount of free heat from little pieces of wood. The materials you need to build this rocket mass heater are copper coil , PVC pipes to make mould, clay and sand mixture, a frame for support, storage tank or drum ,oil, wood as fuel. The stove sits on a frame made from a wooden piece. Here an old chair is used as a base for support. The cob mixture made from clay, sand and water is poured on top of the frame as it is raised up. The next step is make hole for the air intake at the base of the stove. Also another hole is made for fuel intake at an angle to the base. We use PVC pipes as mould to make these holes. We lubricate the pipes with oil before covering them with mud so that they can be easily removed once the mould has been set and dry. A half cut lubricated PVC pipe is placed at the base of the support frame in front of another PVC which forms the body of the stove where the copper coil is wrapped. We start covering the PVC pipes with clay and sand mixture around the junction where the pipes meet. Once the mud has been filled and raised up , another PVC pipe at an angle is placed for the fuel intake. The copper coil is inserted into a well greased up PVC pipe . This section acts as the burn chamber where the coil gets heated up with the water inside. The coil is extended at the ends for the intake and the outlet .The bottom side of the coil is the intake of the cold water and the top for the hot water outlet. Fully pack the area around the copper coil and sides of the PVC pipe with the clay mixture such that the copper coils are completely covered . Pack the clay till you reach five to six inches above at the end of the pipe . This is done so that the top can be used for cooking or boiling. Once the clay and sand mixture is completely dried and set, we slowly take the PVC pipes out. Dig out the back end of both the holes so that all of them are connected to form a elbow shaped hole. The intake and the outlet copper tube is then connected to a water storage barrel. The intake pipe is connected near the bottom of the barrel where the cold water settles and the upper end of the copper coil is connected at the top where the hot water is collected. So the cold water that flows into the rocket stove, gets heated through the copper coil, and then due to the thermosiphon effect and natural convection ,the heated water is pumped through the other end of the coil on to the top of the barrel and this way the water is recirculated without the help of any external source. The cold water natural sinks down due to its higher density .The hot water becomes less dense once its heated , therefore it expands and rises up the coil to the water storage tank. Make sure that there is a height difference between the rocket stove and the water storage tank . The rocket stove always should be installed below the storage tank so that cold water naturally descends down into the stove and there is no backwards flow . https://www.youtube.com/watch?v=EUnQVIlAn6M

- DIY Video : How to build a Simple Woodgas generator for small electric RV generatorThis is the build of a simple Wood gas generator for small 5HP electric generator.This is made from simple materials that can be easily found around your home. The main generator here is a 20 gallon garbage can inside I have a wine cooler and inside there I have hung a small steel bowl. It's just connected up to this very long aluminum duck line to my filter and my filter has been filled with wood pellets to also serve as the fuel. . Then the outlet line goes over to an air inlet port.When you burn the gas you have to add air and this is the valve I've designed to allow that. It goes all the way to the RV Gas engine.You can cut off the fuel by using a wire to cut off the fuel pump. We use a 20 gallon garbage can as the filter.So first I use a quarter inch drill to put two holes in here and then I've enlarged it with a nibbler.Put a harbour wire down in the can where the filter medium is dumped. I use pine wood shavings as a filter medium.Use about 1/3 to fill up my 20 gallon. The reactor is basically constructed out of a stainless steel thermos, which is a central cylinder that is double walled and it has like a one inch opening at the bottom. And below that we've just hung a steel mixing bowl that we basically drilled a lot of holes into and then hung by these three chains that you have riveted in. And then we just connected it with a simple 20 foot ordinary dryer duct. The reactor is filled up some wood pellets ,we have stretched out the hose, this will cool the gas into the improved 20 gallon filter. And I'm going to be driving this with a small air mattress pump. And what I've done is I've rigged myself a dimmer control here so I can actually control the speed. https://www.youtube.com/watch?v=5WLuZP71dc0 https://www.youtube.com/watch?v=cLUNw4knlkc https://www.youtube.com/watch?v=uz93cb0zPlk
