DIY Video:How To Turn Your Old Fan Into An Airconditioner AC for cheap.

    This project shows you how can take an old table fan and convert it into a simple ,cheap and easy to make homemade AC .

    The materials needed for the this project are a table fan, 75 gallon per hour fountain pump with valve to control the water flow, multi purpose zip ties ,two 3/8th inch transparent PVC Pipe tube, 15 foot quarter inch copper tube,two hose clamps.

    Unhook the locks if any and remove the screen of the fan. Take the copper coil and wind them across the rims of the fan .Secure them tight on the screen using multi purpose ties.

    Add the screen back to the fan body and then adjust the two ends of the copper coil by bending them to face the back of the fan and secure them using ties.

    Two 3/8 transparent vinyl PVC pipes are connected to the copper tube ends using hose clamps.

    We attach the fountain pump to the end of the vinyl PVC tube that goes straight into our cooler. The recirculated water coming from the other end of the tube goes straight back into the cooler bag. The cooler bag is filled with ice packs and water. The water pump is submerged into the bottom of the bag with ice and water over it.

    The water which is pumped with the help of the fountain pump gets recycled through the vinyl and the copper pipe and moves back into the bag, so you dont need to add more water .Both the pump and fan can be connected to solar generator in case if you want to make the system portable .

    • How to build a Homemade Multi Use Water Purifier that uses no electricity .Works as Water heater and stove burner too….
      This project goes into the build of a simple and cheap two stage DIY water filter.Also doubles as a stove burner. The materials needed for this build are some bricks,bottles,copper coil,activated carbon,sand,gravel I got the sand and activated carbon water filtration part on the far left. In the middle, I've got it heated in a copper coil running on isopropyl alchohol. The purified water is coming out on the right side. The first step is to make the 1st stage filter. We take a 2L bottle cut in half, drilled a quarter inch hole on the bottom and drop in a couple of cotton balls and pack it in there. Next step is to add the activated carbon,sand and gravel.Rinse all of them before adding . Align the bricks and place the cans on top. Place a small tin with the isopropyl alcohol inside the middle can. A copper coil is inserted into the middle can and connect between the first can and the water bottle. Add the sand mixture filter bottle on top of the first can below the copper pipe. For the first can the one that holds the activated carbon filter,just remove the label and drill one small hole at the bottom. Then for the second cam that holds the copper coil, you cut down the top, take about a third of circumference off and cut about two thirds of the way down. Then put one small notch on the top and a hole down below for the coil. To make the copper coil just wrap it around from top to bottom in a smallcan, push the can out and leave about a foot on either side. Notice I added a couple of bricks and pointed the end of the copper tubing down directly into the can so we won't lose hardly any water and make sure to drill those steam vents so the pressure doesn't build up. Make sure to drill vents on the bottle so that the pressure doesn't get build up. Pour the alcohol under the coil and fire it up. Just put a little in ,you don't need too much. A full glass of water gets purified in three to three and a half minutes. This gravity fed two stage water filter should take care of pond water stream water swamp water, just about any water you can think of. Don't try using this without the heavy sand gravel and activated carbon in there or the water will backflow and it may spray out. An easy way to store this filter when you're not using it is just save the bottom half of the two liter bottle you cut in half and drop the filter in it ,holds it perfectly. This cheap 2 stage heated oil water purifier can also be used to both purify water and cook at the same time.
    • How to Install a Complete Micro Hydro Alternative Free Power Generation System for your Home.
      This project goes over the details on how you can setup and install a 300W Off the grid Micro Hydro System for your home . The water source mentioned in this project have a flow rate of 15 - 30 gallons a minute and the drop between the source and the house is about 150 feet. The first step is to make an intake angled screen box for the system that helps in channeling the water from the source. The aluminum screen on the top blocks leaves, sticks and other debris to pass through into the box . The box is made of a 24 inch 2X10 ,2X4 and an 2X8 angled piece treated lumber. We add 3 one and quarter inch attachment points on the lower side of the box for the hdpe poly pipes. The box is secured using exterior screws on the outside and inner tubes on the seam to prevent leaks. The box is installed on the creek with help of couple of three and half inch concrete anchors and two boards are screwed on both the sides for support. The outlet poly pipes from the intake screen box goes to 55 gallon plastic barrel which acts as a silt catchment and also an air free source. The 3 outlet pipes are connected to the top of the barrel with the help of uniseal rubber gaskets. A 2 inch pipe is installed midway on the tank for the penstock. We also install an overflow pipe near the top of the tank to take the extra water out and a three inch cleanout pipe at the bottom . The cleanout pipe can be unscrewed to remove the silt and debris out. To take the water from the intake to the turbine, the penstock used here is a 100PSI 1100ft 2 inch poly pipe. A threaded adapter is glued to the outlet coming out of the barrel. It is then connected to a two inch full port shutoff ball valve followed by an another threaded adapter and a pipe. The penstock poly pipe is attached to this pipe using barb fittings with hose clamps. Next step is to install the pressure gauge and the surge tank to our penstock pipe. Water will come down through the poly pipe into another PVC pipe fitted with a pressure gauge, surge tank, two inch closing ball valve and a union to remove the turbine from the pipe. The surge tank is made of a standpipe that will prevent any water hammer affecting the pipes. The two inch poly pipe coming out from the barrel is connected to the two inch PVC surge tank and pressure gauge using regular . If the main shut off valve is suddenly closed, this tank will allow some of the surge to be absorbed. Next step is to build a housing for the micro hydro turbine. It is going to have a lid that opens up and a drain field pipe that goes out back to the creek. The housing for the turbine is made of three quarter inch plywood that is 2 X 2 foot wide and one foot tall. The turbine sits inside the hosing in the middle with the help of some 2x 4 scrap wood and a bucket lid piece. Then a 3 inch exit pipe comes out of here down through the middle of the housing .This drain pipe keeps the water from piling up under the turbine. The Micro Hydro Turgo Turbine is custom built based on the head pressure and the flow rate of the water source. It has three ball valves and four quarter inch jet nozzles coming out of them. The ball valves can be separately turned off when there is not enough water .The turbine is wired up to be three phase. The water coming out of the penstock hits jet nozzles that turns the Pelton wheel which is connected to 3 phase AC motor. To connect the turbine to our house, we use a 10/3 underground feeder wire. The wire is enclosed in a one inch conduit pipe. The proper way to install wire into a conduit is to get your conduit all glued together. And then you have a vacuum that pulls a string through. You tie your string to the wire and then pull the wire through the conduit. The wire goes into the house through a PVC conduit body. We install a junction box on the housing of the turbine to join the 3 phase turbine output wires to the 10/3 UG feeder wires coming from the house. Inside the house, we connect a rectifier to the three legs of the three phase coming from the turbine .This converts the AC generated into DC power. To generate useable power from this micro hydro system we need to install certain electrical devices in our houses. These include the MPPT Charge Controller, Grid Tie limiter Inverter, breaker box, disconnect switches and the batteries. These components are mounted on a 2 X 2 foot ,three inch plywood board. In case there is some excess heat for one of these electronics at some point, we cover the plywood board with a piece of sheet metal so that it will act as a heat sink. From the rectifier, the connection goes into a 25amp breaker box .The red wire goes into the breaker box and then further connects to positive of the charge controller. The negative white wire is directly connected to the negative of the charge controller. The five 12V AGM batteries are connected in series using four gauge cables. The positives from the batteries are connected to the charge controller and the inverter via DC switches .These switches allows us to isolate and disconnect the components individually. The negatives from the batteries are connected to the negatives of both charge controller and inverter respectively. The inverter is further connected to receptacle from where it goes straight to the main supply.
    • How to build a Super Efficient Portable Rocket Mass Heater from reclaimed and repurposed items and save up to 80% on your heating bills
      This 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.
