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 .
- How to set up a Complete Off the grid living System using Solar and Wind Turbines . Make your own Power and never pay for electricity again.If you're going to run your home ,cabin or garage off grid, you are going to need some way of having power. Enter Solar and Wind. This project goes over the build of a complete off grid power generation system that can harness the clean and green renewable energy of the sun and the wind. Here is the basic rundown of the system .We go from sun to solar panels, there is no limit on how many solar panels we can put. It goes into a charge controller, it helps the solar panels create really efficient electricity to be pumped into your battery bank. Charge controller also makes sure that the batteries are being charged correctly and stay optimum. So solar panels to charge controller, and then that goes directly to your battery bank. The other source of renewable power is wind. The wind turbine is connected to a stop switch that goes into your battery bank. In some cases in between you can put up a wind turbine charge controller. Next step is converting the DC power to AC power with an inverter. The inverter basically converts the power to make it usable for your home. The inverter also has to be sized appropriately. From inverter to breaker panel which spreads the the power out throughout your house through your light switches, wall sockets. From breaker panel straight to your house or cabin. The first step is sizing your system. The battery voltage is going to determine what type of equipment you are going to be buying, and how you are going to be wiring your battery bank. So if you go with a 12 volt system, then you are going to want to make sure that your solar panels are wired up correctly for 12 volt. Even when you go with a wind turbine, you are going to want to make sure you buy the correct wind turbine for your battery voltage .So everything has to be sized appropriately so that you can collect as much energies as efficiently and then you can draw that power out. The golf cart batteries in my system are of 6 Volts. I have 6 of them wired in parallel, and in series to give me a 12 volt battery bank. The control panel box consists of my charge controller, voltmeter and 2 ammeters for both reading both solar and wind power amps. Four 12V Solar panels , each 100 watts are wired together . All the positives are connected to each other and all the negatives are connected to each other. The wiring goes straight into the control panel. The wind turbine used here is also 12V.The 3 Phase connections from the turbine goes into the bridge rectifier. The negative connection from the rectifier goes straight to the batteries, the positive goes to a junction box that connects the turbine and the inline fuse and 50amp breaker. The negative of the inverter goes into the negative of the batteries ,positive to positive. The romex wire from the inverter goes into the breaker panel in the house. The Permanent Motor Alternator turbine stands on a 6 foot pole .We have these two steel pipes that go down into the ground, three feet. There's another piece of steel that runs across here that's welded together, and it's in the bottom, and then we poured concrete over it to anchor it. Three tie down points are connected to the turbine to keep the pole steady from rocking around especially in high winds. So that way, when the blades turn, the bearings don't get worn out prematurely from wobbling. The Permanent Motor Alternator (PMA) used in this turbine consists of 2 shell casing, two bearings, a rotor inside and a stainless steel shaft. The tail of the turbine is made from a sheet metal cut to look like a fin.It is attached to a steel pole.This is further connected to the PMA alternator. The 11 blades of the turbine is attached to a hub and a pulley through a steel shaft. The belt is connected to a secondary pulley which is connected to the Permanent magnet alternator. The wire from the PMA is connected through MC4 connectors to the control panel. https://www.youtube.com/watch?v=4zi99DBWW0o Wind turbine and solar power system overview : https://www.youtube.com/watch?v=jT8yswXdxFk https://www.youtube.com/watch?v=uXKDy_BgdL0 https://www.youtube.com/watch?v=3DRfsjyCPXM https://www.youtube.com/watch?v=WTN7cMLE0ec Setup of the wind turbines : https://www.youtube.com/watch?v=QDUxNU8t-TU
- How to build a Super Efficient Portable Rocket Mass Heater from reclaimed and repurposed items and save up to 80% on your heating billsThis project goes over the build of a homemade efficient rocket mass heater which is portable ,uses less fuel and burns clean. This heater is made out of reclaimed and repurposed materials. The cool thing about a rocket mass heater is that it stays warm long long after the fire is out. The whole thing is powered by a rocket stove, which is a j shaped burn chamber. Fuel goes in the short side of the J, the fire burned sideways and the bottom of it. And then the draw is created by a tall vertical heat riser. The gases then come out of that chimney go all around the inside of the barrel, a lot of the heat is given off into the room right off of the barrel. That's your radiant heat source for the room. The barrel acts as that radiant heat source. The gases then go through a valve in the barrel down below and through a series of tubes that are encased in mass such as aircrete or cob .The gases are able to shed the heat into the cob. And the cob stores it as a thermal battery. The gases make its rounds through the tubes and goes out through the exhaust pipe. The rocket mass heater shown here is made of a burn chamber, heat riser, bench for containing the tubes , the exhaust pipe and an insulation refractory material like aircrete which is a high temperature cement mix. The burn chamber is made from an old sheet metal pressure tank and a stainless steel water heater tank. The pressure tank insulated with aerated concrete sits inside the water heater tank. The combustion or gasification chamber is connected to the heat riser chimney through a three inch pipe insulated inside a six inch pipe. This pipe is also insulated with a refractory mix. The vortex chamber is connected to this pipe. The vortex chamber is made from a saw blade and a left over piece of pressure tank material . It is insulated with the refractory material . Six glue stick 3/8th inch air holes are drilled at right angles around this refractory material that creates a vortex extra air suction effect .So as that heat comes up and creates a negative pressure up the riser, it swirls around the vortex chamber and enhances the burn. The initial combustion creates enough heat to release way more gases than it has oxygen to burn. By introducing a vortex air intake system, the burn output is amplified. For making the insulated heat riser, we are going to use an aerated concrete refractory material called aircrete . We make the mould for the four inch heater riser using a metal mesh fabric, sarnafil roofing material and a thin gauge wire. Then it is filled it clay sand up to to the top . We take this mould and put it inside the six inch stove pipe and pour aircete through the sides all the way up to the top and let them sit to cure. We pull the sand out of the center of the heat riser. And then eject the liner that went against the inner fabric webbing that acted as a mold for the aircrete. The Aircrete heat riser is installed on top of the vortex chamber .The heat riser is double insulated with a old water tank and an old 55 gal oil barrel. Also the water tank is insulated from the 55 gal barrel using some pea gravel .The insulated water tank has an outlet pipe at the bottom for extension into the mass bench . The exhaust pipe coming out the insulated heat riser has a two foot drop to a directional valve connecting two pipes ,one pipe acts as a flue chimney that goes out into the outdoors through the window, the other goes into the mass bench. The valve allows us to redirect the air to pass to the bench once the heat riser is all warm. The eight foot long wooden mass bench houses the six inch stove pipes coming out the exhaust of the heat riser. It has a mylar reflective insulation sheet on the floor. This helps prevent the heat escape through the floor .The mass bench is then insulated with pea gravel which absorbs the heat and holds it and slowly radiate out over a period of time. The pipe coming out of the bench goes out of the window through the valve. The flue chimney pipe that goes out through the window to the outdoors is made of double walled stove pipe. A five inch pipe is inserted inside a seven inch pipe. The space between them is insulated with a aerated concrete refractory material .All this insulated exhaust pipe is doing is taking and adding an element of acceleration up the chimney to negate the net negative you get from dropping two feet down into the bench from the heat riser. https://www.youtube.com/watch?v=o1ZKm7QZ-dY
- 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
