How to build a Homemade Archimedes Screw Turbine using PVC parts to generate Off the grid Power from a flowing river or stream/creek

    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.

      This project goes over the build of an DIY Atmospheric Water Generator that distills water from air. This unit is made of aluminum and copper components so it is water safe and is drinkable. The water essentially is just pure distilled water just as clean as if it is distilled from a stovetop distiller. This setup works well in hot humid weather. Also acts a dehumidifier. The materials you need to build this project are quarter inch copper tubing, soup can, half inch PVC pipe, 12V DC aquarium pump, aluminum foil, clear vinyl tubing, aluminum tray for collecting the distilled water ,small styrofoam cooler box. Cold Water is pumped through two sets of coiled copper tubes. The coil becomes freezing cold and starts to condensate . Dew gets collected on the coil and is captured by a drip pan which is placed under the coil. The copper tubes are wrapped around a soup can to get the coiled shape. The clear PVC hose tube is clamped onto the coil and then connected to a small 12V DC aquarium water pump which is powered by a battery or solar panel. We take two half inch PVC pipes , connect them together with two elbows . Wrap the PVC pipes with some aluminum foil and place the pipes above an aluminum or glass tray. The water pump is then submerged in a chest box or bucket containing ice cold water. The pump is started and water coming out of the box cooler is sent through the copper coil where it will start the condensation process. Here the water is chilled to below its dew point. If the water is warm, it wont cool the copper coil enough for the condensation to occur. The colder the water and the more humid it is out , the faster the process of collecting distilled water. To improve the efficiency , you could squeeze the copper coils together . The more the coils, the more the water you can extract from air . https://www.youtube.com/watch?v=ksOr7lX_RVU
    • DIY Video: Get unlimited hot water for free without electricity by building a Thermo Siphoning Rocket Mass Off grid Hot Water Heater
      The device is known as a rocket mass hot water heater and they can be made very cheap as you can see in the video. The only cost was about 50$ worth of copper pipe. The sand and clay mixture was about 50% clay/mud and 50 sand, for most of the build. Some people also call these things rocket stoves. One thing's for sure, this primitive technology is a cheap and effective way to get off grid hot water for free. The ancient knowledge we are taking advantage of in this case is something called thermo siphoning. Some know a similar design known as a cob oven.

    • How to build your own DIY off grid / grid down Solar Power Back up system from scratch
      This project goes over the build of a Solar Power Grid Down Backup System to generate your own alternative power.A great way to utilize renewable energy as a backup source of power. Whatever may be the reason , may be to offset electricity bills or for self reliance to provide when the grid goes down, a solar backup system is simply a great way to provide alternative power to maintain a lifestyle of reasonable convenience. If the grid should go down, I can have a freezer, power lighting, pump water, maintain communications, use tools, and charge every little device I have from flashlights to kindles. This Off grid Solar Power System is composed of 5 components. Solar panels to generate the power, a charge controller to charge the batteries, the batteries to store the energy, the inverter to provide AC to the household items you wish to power. Also you need a Kilowatt meter. The kilowatt meter measures two things you have to know how much energy your devices draw at any given moment, and how much power they consume over time. Here we use 100 watt monocrystalline panels, a 40 amp MPPT charge controller, a 1000 watt pure sine wave inverter and to store the energy, 446 volt golf cart batteries totaling 470 amp hours. First you need to size your system by figuring out how many devices you are going to want to run at the same time. This will determine the size of your inverter, the inverters function is to take DC power from the batteries and converted to AC power for use with household appliances. If I have 1000 watt inverter, this means I can run up to 1000 watts worth of devices at the same time. Once you have evaluated every device that you feel that you are going to need, should the grid go down, you are gonna have a good idea of how much power you need to generate each day. The battery bank consists of four, six volt, Duracell SLIGC 125, golf cart batteries connected in series. Golf cart batteries are designed to deliver a lower amount of power over a longer period of time and then recharge quickly. When picking a spot to locate your panels, you have to consider that the sun will be lower towards the horizon in the winter, and closer to directly overhead in the summer. Building a system that actually tracks the sun would be best as the panels are always pointed directly at the sun. Also mount your panels as close as possible to the batteries. This is because the longer your wire run, the more energy is wasted due to resistance. You also need to select the proper gauge wire to transmit the power from the solar panels to the batteries. Between the panels and the batteries is the charge controller ,it controls the charge of the batteries and make sure that the batteries get the proper voltage that they need and that they don't get overcharged. Here we use an MPPT Solar Charge controller. If your solar panels are wired in series and connected to an MPPT charge controller, the voltage adds up ,thus giving us enough voltage to charge the batteries. An MPPT charge controller can charge your batteries nearly the entire time The sun is out. If your panels are far away and you want to save money and wiring, then the MPPT charge controller is way more efficient than PWM. The first step in making your solar system safe is making sure that there's an automatic and a manual way to disconnect power in each segment of the system. Starting right here at the battery box we have a 300 amp manual switch to kill the power from the batteries to the inverter as well as a 200 amp fuse that will blow automatically. Another component to the safety is the grounding. Grounding your system is quite easy to do. So get an eight foot grounding rod and drive it into the ground. Then pick up some copper grounding wire, some lugs and connect the frames have all the panels in any metal components in the system including the charge controller and the inverter.
