How to build a Homemade Micro Wind Turbine for under $50 that can be mounted anywhere

    This project goes in the detail on how to build a mini wind turbine..The wind turbine is a nice addition to your solar generator system for times when it’s cloudy and you are not receiving as much sunlight as you normally

    First step is to build some cheap PVC blades, what kind of motor we’re going to be using and how we’re going to attach this to the motor.
    We are making six blades or rotors here.What we want to do is we want to cut our PVC pipe to length first.

    Once you’ve got it cut to length, then you want to take your your straight edge again and and Marco line down the center and cut it in half. Make sure that you do that on both sides. One on this side, one on this side. And that they’re perfectly in the middle so that you’ll get two even sides.

    We need to cut a small little block down at the blade end, where we are going to put a drill hole and put a screw through it so that it attaches to the hub.On the top of the blade, we’re going to cut away some of the material to resemble a swept wing, kind of at an angle.

    These are 14 inch long blades that is attached to the hub using set screws attached to the motor. The 12V motor used here is a 300 RPM geared motor which would be its maximum speed and it produces 600 milliamps when its fully loaded.

    The motor is placed inside a One and half inch PVC pipe ,another PVC Tee is connected from where the wires will down to the bottom where another 7 foot pipe that act as the tower or pole.

    The end of the pole goes into a shower drain which is then attached to piece of wood that acts a solid base.

    For the YAW system at the back end,a tail vane is made of a cheap flashing material that is bolted between an 8 inch piece of PVC.Put a hole through the middle of it with a bolt in between so that it can’t move anywhere.

    We use an an old OSB for the base, size is about seven inches square. And then I just have a piece of treated lumber on the bottom. It’s attached to this ball bearings so it can spin around. The Shower drain PVC is placed in the middle through some ball bearings. Route the wiring down through the hole for to connect to the charge controller.

    Next step is the wiring through the piping.We just need to connect these terminals to the appropriate sides of the motor.

    • DIY Video:How to build a Homemade Double Barrel Garage Heater out of Old Water Tanks .Efficient,clean burn and cheap!
      This project goes over the build of Double Barrel Stove out of two old scrap water heaters for the shop. The first step is to disassemble both the old electric hot water heaters to get their tanks out. Take a grinder and cut a section off from the top of the water heater tank. This tank will become the bottom tank. Remove any calcium and mineral that ends up developing deposits inside the bottom of the tank. Take a 12 gauge plate steel and put our top drum upside down and scribe a circle out of them from the end and cut it. Weld the steel piece onto the drum. You need to do the same for the other drum too because with these double barrels, you are basically making two stoves, just connecting them in the middle. Now both the top tank and bottom tank ends have been polished and cleaned .Remove any insulations, paints and glues from them if they have any. Make sure all the rough pieces on the tank are welded on ground down. Cut a small piece of pipe that acts as stack between the 2 tank. Next step is to add a small support bracket on the top of the bottom tank that will help support the top tank. Cut a hole on the bottom tank .This will be where the stack goes between two of them. Fill the drain plug down at the bottom . Take the top tank, cut and weld the top exhaust stack that will be six inch outlet for the smoke. We also add a six inch inlet that goes up to the top that forces your your smoke and the gas has to go across the length of the barrel. The bottom barrel will be connected to this. Both barrels are welded together, the bottom barrel is welded onto the mid stack which connects the top barrel with the exhaust stack. In order to support the barrels, we take the scrap pipes lying around and make legs as a support structure for the stove. Next is the door fabrication. We cut a hole for the door in the bottom barrel. A couple of hinges, door catch are welded on to this end. An air inlet pipe is threaded onto a plate. The whole unit is then attached to the door. A handle is attached to the inlet pipe so you can open and close whenever you want to control the flow of the air intake. https://www.youtube.com/watch?v=fTj4pjJ4DT0
    • How to build a Simple Homemade Water Distiller that turns dirty water/salt water into clean fresh pure water
      This project goes over the build of a Simple and cheap Homemade Stovetop Water Distiller.Turn your dirty,salt water into fresh drinking clean water fast.This setup is great for everyday or emergency use. Assembles/disassembles fast for easy portability. The material needed to make this distiller are : A teapot,10 feet copper coil, corrugated stainless steel or copper tube. The water source coupling is connected to a foot and a half corrugated three quarter inch copper pipe that further reduces to the half inch and then this is a connected to a 10 foot roll a half inch copper tubing. The three quarter inch threaded two half adapter is soldered to the 10 foot copper coil tubing. Bend the tube into a tight spiral. A Stainless steel or copper foot and half corrugated pipe goes into the 10 feet twisted copper coil. The end of the corrugated pipe goes into tea pot or water source connector. A total of 12 feet of coil. The steam rises without bringing any of the impurities along with it. The steam travels through the coils and slowly cools and condenses. It finally condenses back to its liquid form and drips out as clean water. In order to make it even go faster, put some cold towels around the coil or even submerged in water. A little bit of aluminum foil over the top is kept and the copper tube is extended down a little bit into the glass jar. Everything stays completely tight the whole time. You can make this distiller with that single corrugated copper tubing, but the more copper we add, the more time it has to condense down into purified liquid water. During the test,we have managed to acheive half a gallon in 2.5 hours. You can use this on the stovetop, rocket stove campfire, even a parabolic concentrator like dish cooker. Anyway to get that water boiling, then just hook it up like this. Makes tons of clean water really fast. https://www.youtube.com/watch?v=KoEn5kfpTYI
    • DIY Video : How to build a Thermal siphoning rocket stove for an off grid water system. Clean and efficient burn
      This Video shows the build of a Thermal siphoning rocket stove for an off grid water system. The advantage of the rocket stove is a clean and efficient burn. This system uses 5 metres of 20mm annealed copper pipe, and though I designed the rocket in a J configuration, it worked better as a batch box. There is a vortex generator at the base of the riser and basically I was able to heat 200 litres of cool water straight out of the tap to 67 degrees Celcius / 152.7 F in 1.5 hrs.
