This project goes over the build of a Homemade Copper Pipe Solar Thermal Water heater which can produce super hot water fast .This reaches temperature at or above 150F with air temperature from high 40’s to low 50’s.
Here are the materials needed for this project are :
Two 10 foot half inch copper pipes – Type L
16 half inch 90 degree elbows
18 tube straps
23 X 35 half inch plywood for the back
18 X 20 half inch plywood for the pipe support
2 X 2 lumber at 20 and 35″ for the sides
4 and 3/8 inch square dowel rods for the glass support
1/2 inch threaded pipe adapter
3/4″ to 1/2″ garden hose PVC adapter
1/2 inch coupler.
The first step is to cut down a bunch of two foot sections out of the 10 foot sections using a copper cutter. We cut 7 of them and 2 more for the top and bottom which are 30 inches each.
Next we cut 8 sections of 1 1/8″ for the connecter pieces between elbow joints. This allows the pipe to be spaced exactly two inches apart on the board evenly all the way up and down
Connect the pipes using couple of elbows and a 2 inch connecter piece and solder them .Do it for the rest of the pipes.
Slide the pipes into the plywood frame collector and fasten them onto it using 3/8 inch screws to be more secure. A small internal board is placed onto this frame which helps the pipe to lay flat inside .Also it holds the pipe at right height so that it exits through the right holes. It allows for the pipe to be easily removed from the collector frame.
Cut the wooden dowel rods and put inside the collector to support the glass. Sand them a little bit so that the copper pipe will fit back through.
A straight coupler is welded on to the end of outlet then you can add any pipe or connecter or wherever you want the water to go.
The inner board is secured to the back board using some three quarter inch screws. The 4 corners of the 2 X 2 wood frame is secured using 2 and half inch wood screws and the corners of the back board is secured by one and one half inch screws.
A 20 X 32 inch glass is placed on the frame with the help of some silicone caulk around the edge. The highest piece of copper in there is eighth of an inch away from the glass and its painted black.
- How to build a Offgrid Homemade Emergency Washing Machine that use no electricity.Also works as a ComposterThis project goes over the detail on how you can take an old 55 gallon plastic drum and turn that into a hand crank washing machine and a compost tumbler. The frameworks has uprights on the edges, holding up the barrel all the way down. The upright on the sides are 3 foot long 2 x 4. The base that it sits is 3 foot 2 X 4.Long brace that holds the two sides together is three foot eight inches long. You can take apart the whole framework by unscrewing the side rails and store the barrel for using them in an emergency situation. The barrel sits on a one inch hardwood dowel which is installed through one inch hole at the top of the upright. These barrels have a line in the middle of them so it is pretty easy to find the center by measuring across the line and then dividing it in half. The hand crank is made of PVC pipe with some screws to the end side of the barrel. The hand crank gives you something to grab onto if it gets very heavy so you can pull it back up and really move it around. It has a one foot by one foot door on the front .We use couple of cheap cabinet hinges to hold the door up when unloading the clothes. It also has a little S hook latch that locks it into place. A hole down in the middle of the barrel is for drainage. A small plug and a cap acts as a drain. The plug is put through the hole from inside and sealed with the help of PVC glue. Next step is to add agitators to our barrel . As you rotate the barrel, the clothes will roll over those agitators back and forth and get the clothes moving a lot better and help clean it. We add 3 PVC pipes inside the barrel that act as the agitators. You put clothes in through the top and add enough water just to cover the clothes, add any biodegradable liquid detergent and close the lid. Start moving the hand crank back and forth. This will agitate the clothes. The agitators slosh those clothes around, get them grinding against each other and that is going to clean all the dirt out of them. After about 15 minutes of agitation, we pull the drainage plug off the bottom and drain the water or recycle it by collecting them underneath a bucket and pour it around your plants and trees. As long as we are using biodegradable soap/detergent, the soap and the dirt that is in your clothes isn't going to hurt the plants. We put the plug back on, and fill the barrel with some clean water and agitate for another 15 minutes. This is the rinse cycle. Pull the plug, drain that water or use it on your plants. This setup can be also used a tumbling composter. Compost can be made of just about anything that was once alive .You can use leaves, grass clippings, garden waste, kitchen waste, chicken manure or any other waste material. Just dump all in there and turn the compost in there using our handle every couple of days for 2 weeks. We want to keep the compost aerated so that the microbes and bacteria that break down the compost can utilize the oxygen efficiently and help in decomposition. After 2 to 3 weeks, you probably have some pretty decent compost that you can use on your garden. Also through the drain hole, we can collect the residue compost tea which is high in nutrients. You can use that compost tea for plants that really need a good dose of nitrogen.
- DIY Video : How to build a Simple Homemade PVC Wind Turbine Generator with Swivel Top .Produces electricity to run lights, charge batteriesThis project goes into the build of a DIY swivel top wind turbine generator that can generate off the grid electric power to run lights, radios, charge batteries. This durable, lightweight and portable wind turbine would be very useful in SHTF / Power outage / Emergency situations. The materials you need to build this wind turbine are as follows. 3/4th inch PVC pipes including 5 90 degree couplers, 3 Tee couplers,4 Three and half inch pipe, Two 8 inch pipe, Two 3 inch pipe and long 11 inch pipe for the post. The propeller for the turbine is made from a 5 gallon bucket lid or you can buy them from your local hobby store, 3V 350ma DC hobby motor, wire from an old extension cord. The base stand for the turbine is assembled using the PVC couplers and the tee's. The 11 inch PVC post pipe is finally attached at the center of the support base. Use PVC pipe cement to strengthen the connection between the joints. Next step is to make a hole at the bottom of the post for the electrical cord . A hole is drilled one inch from the end of the PVC pipe. The wires from a broken extension cord is used for this project. The wires are soldered to the ends of the motor first for a good tight connection. The wire is fed through the pipe and the motor is mounted at the top . A duct tape is wrapped around the motor multiple times so that it fits the entrance of the pipe opening. Before encasing the motor, the blade is put on . To build the swivel assembly ,we need a PVC union, an adapter, 3 inch pipe. The adapter is screwed on to the union, the 3 inch pipe is then connected to the adapter. The tail fins are made from an old waste basket. The fins are screwed on the post using machine screws. To stop the post from rotating 180 degree in both directions, we put couple of screws on either direction on the side of the post in such a way that it prevents the post from rotating 180 degree . Not only you can charge your batteries using this set , but this can be connected to an inverter to run AC powered appliances. https://www.youtube.com/watch?v=kMZdAf9hrFk
- How to build a Homemade Water Powered HHO Dry Cell GeneratorThis project goes over the build of a Homemade 19 Plate HHO Dry Cell Generator . The HHO generator works by the principle of electrolysis. Water is made from two types of atoms hydrogen and oxygen. Electrolysis is a method for splitting water into hydrogen and oxygen. Pure water isn't electrically conductive, so we add either sodium hydroxide or potassium hydroxide to it to make it conductive. To make the electrolyzer , we need electrode plates, neutral plates, gaskets, front and back plates with some metal reinforcements . The electrode plates and the neutral plates are made of 304 stainless steel sheets, the gaskets made from one eighth inch neoprene rubber sheet. The neutral plates are stacked in between the positive and the negative plates .The empty spaces are filled with neoprene gaskets. Water comes into the electrolyzer through the input tube and goes out as hydrogen and oxygen through the output tube. When electricity is applied to the electrodes, the chemical reaction occurs, which causes the hydrogen from the water to go to one plate and the oxygen to the other plate where there they form bubbles of gas .Now the electricity wants to jump from the negative plate to the positive plate but since we have neutral plates between them, they divide the original voltage. This help in efficient HHO gas generation. The plates are made of 12 X 12 .24ga 304 stainless steel sheets that is cut into four 6 inch pieces using tin snips . The plates are stacked together and holes are cut top and bottom for where the gas and the water comes in and leaves. To hold the plates together use seven inch cutting boards with metal support frames at both ends. To differentiate between neutral plates and the electrode plates, we cut both corners of the neutral plates and only one corner of the electrode plates. So this way we can run a bolt from the positive to the other positive and negative to other negative end. To assemble the cell, we place onto the base cutting board, the positive electrode plate and stack the neutral plates and the gaskets on them one by one and enclose them the negative electrode plate and the base board .Secure them with bolts on four corners. The electrode plates are then connected to each other with a thin gauge wire. The next component for the build is some sort of a water reservoir. The reservoir is nothing more than a bottle that's going to hold your electrolyte, which is distilled water and either sodium hydroxide. The water reservoir is connected to the cell using two three eighth inch tubes, one going into the cell and other coming out . The other component that you're going to need to build this HHO generator is some kind of a power supply that can generate 12V 30amps . This can be a car battery hooked up to a trickle charger, an old computer UPS supply or a 12V battery used for solar panels. The electrode cells are then secured on a wooden frame along with the power supply and the water bottle reservoir for easy portability. Next you need a bubbler .This takes the HHO gas coming into it and diffuses them and gets broken into smaller bubbles. As those bubbles travel up the column of water inside the bubbler, it helps to filter out the sodium hydroxide or potassium hydroxide vapors .If your bubbler is set up correctly, then after being diffused and traveling up that column of water, it tends to get rid of most if not all those vapors. To add a safety feature ,we drill the top of the bottle , remove the lid and cover it up with a plastic foil pressure membrane . If the pressure inside the bubbler increases in case of a flashback ,instead of the jar exploding, the pressure is able to escape through the membrane . https://www.youtube.com/watch?v=ILzMhqEFMeI
