    • How to build a Homemade DIY Geothermal Heat Exchanger to Cool Your Garage
      This project goes over the build of a Geothermal heat pump that takes the hot air in your garage and cool it down by transferring that heat into water .The cold water is pulled out of the ground through a shallow hand dug well and send to a heat exchanger inside the garage . A fan attached to the heat exchanger blows out the cold air into the garage . The heat exchanger absorbs the existing heat inside the garage . The warmed up water is then removed through an exhaust pipe. Just a few feet down the earth is a consistent 55 degrees, summer or winter. Water at that depth is about the same temperature. To harness the cold water down below, we dig a shallow well. To do this we use a post auger and a 3 foot long well point that is attached to a 10 foot three quarter inch pipe using a drive coupling. We start by digging a hole using the post auger till the water table is reached and then start driving using the well point for additional two to three feet until it is submerged under the water table. A two to three foot trench is dug from where the well is installed to the garage . A One inch poly pipe is connected to the well pipe using a barbed coupling and is buried inside the two foot trench all the way to a well jet pump .The trench is dug down at least two feet until you hit some hard pan clay that is about where the temperatures begins being more constant. This keeps the pipe cool under the earth. The other end of the poly pipe coming out from the trench is connected a 1/2 HP Flotec Shallow well jet pump . The pump can be powered by a solar panel. The pump is kept outside the garage as it generates a lot of heat. If it is kept inside the garage, cooling effect from the water will be undone by the heat generated by the pump. The output of the pump is connected to a three quarter inch copper pipe inside the garage. It is then further connected to a water pressure tank with the help of a brass tee and a union. A relief valve is also attached to the tee to empty the water tank if the pressure gets too high. A water pressure tank is used prevent the pump from failure .It also acts as a buffer storage. The other end of the brass tee is connected to two pipes. One pipe goes outside the garage to a faucet and the other pipe is connected to a radiator that acts as a finned tube heat exchanger. The heat exchanger captures the hot air surrounding the garage and stores the heat into the finned coils within the radiator .The heat is transferred to the water flowing through them . An exhaust line from the radiator carries this hot water to outside the garage. Two flexible hose pipes connects the input of the heat exchanger to the water tank and output to an exhaust pipe. A box fan is placed in the front of the radiator to blow the cool air . The fan can be powered by Solar panels. Once the water starts running through the radiator , we start the fan
    • 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.
    • How to build a Multi Use Simple Homemade Wood Gas System from Scrap Materials that can be used as a Generator,Cooking Stove and Lantern
      This project goes over the build of a simple gasification system that functions to produce wood gas for running a generator, a cooking stove and for lanterns. We feed the wood chips and other materials through the opening at the top of the gasifier ,the air also gets drawn in from the top .The air would drop through the wood mass, down to the reduction zone and gets collected down at the bottom of the tank through the output pipe . The materials needed to build this down draft style gasifier are a 3 old propane tanks, old steel sheets, wood pellets. The first step is to make sure that propane tanks are empty .Remove the handles from the top of the 3 propane tanks and unthread the valves. Cut the top portion from 2 tanks and stack the body of the tanks on top of each other and weld it. One of the cut out top pieces can be used a lid . The bottom portion of the lower tank is cut open to create the reduction zone of the gasifier. To make the reduction point, we take the scrap steel sheet and make a five inch wide small tube of the them and weld them to the bottom third propane tank . The bottom five gallon propane tank is used as a ash bin where all the ash is going to get caught and as an outlet for all the gases coming out of the system. The top portion of this tank is cut in such a way that it fits the reduction zone collar of the secondary tank. Make sure that both the tanks fits nicely together so that you can pull the inner chamber out of the bottom ash tank to remove it, dump the ash catch out and use it again and again. The top of the upper tank is cut open .This acts as the feed area where all the wood pieces are dropped in. We make a screen with holes using a 20mm hole saw cutter from the leftover cutouts of the propane tank. We are gonna mount this screen inside the gasifier lower reduction zone. A hinge and a wire is attached to the screen so it can open and close. This gives us the ability so we can shake the screen if it plugs up with ash or other materials. The wire goes through the reactor up to the top . We have a pressure relief system installed on the lid of the gasifier. If anything were to happen inside of the gasifier , the build up pressure can be made to escape through the top lid .This is done by hooking up two springs on both sides of the lid through small loops .The springs on both sides is attached to hand levers. We drill 8 half inch diameter holes just above reduction zone area and put thick steel tubing through them to the center of the chamber. The airflow will go in and be drawn down through the center of the reduction zone that helps in efficient burn. The pipes are curved in to the chamber so that it does not interfere with any wood mass as it goes into the reduction zone. We add plugs along these 8 tubes to regulate the air flow into the system. Next step is to add the draw fan to the gasifier. Here we use a pellet stove fan .We add a 2 inch plate over the face of the fan and a threaded pipe to seal any air going into the gasifier. We start up the gasifier by putting some chopped wood through the top and use the fan to get the wood gas producing out of the bottom outlet pipe.
