DIY Video: How to Recycle Old Used Car Batteries to build a DIY Off Grid Solar PowerWall. Get Off-Grid backup power in case of an emergency

    This Video series shows step by step on how to build a Homemade DIY Off grid Solar Powered PowerWall Backup System using salvaged and used Chevy Car Batteries.Here we are modifying an 18kwh (Gen 2) battery from an Old Chevy Volt EV hybrid, so that I can use the cells in a DIY Powerwall. The original battery is all wired in series for 355 volts. I’m breaking it down into 8 smaller batteries, each with 44 volts.This DIY Powerwall is using Chevy Volt (Gen 2) batteries instead of the usual Tesla or 18650 cells. This set-up will provide me off-grid backup power in case of an emergency.It’s great that we can re-use and recycle these used car batteries.

    • DIY Video : How to Turn old unused ceiling fans into a useful energy producer by building a Wind Turbine out of it
      A Beginner tutorial on how to make a wind turbine ceiling fan.So out of the box, we have the main part here, which has the motor in it.Keep up with all the blades if you can. You can use this for the furrow on the back the way it pushes around to keep the turbine from standing in a very aggressive wind it pushes it out of the way First part is just getting the motor outside of this casing. And you want to be careful because these wires are fragile, and you don't want to tear those loose by any means.So mainly, the tools that you'll need is just a screwdriver, maybe a flathead screwdriver and a hammer eventually. Take the top part of the ceiling fan off, this is the part that's next to the ceiling.Disconnect the wires don't cut them. There's a nut here with a washer that holds this plate.And we don't want this plate. So we need to take that off. However, we do want the washers here. Take this casing apart, and inside you'll see that copper coils that actually power the fan. The next step is finding the highest arm reading of these four wires that is coming out of this motor.Pull that higest ohm reading wires through the center pole to the other side. Insert a metal banding used for attaching the magnets around the stator. Put the magnets inside the fan housing to achieve a voltage reading.Add a cardboard spacer in there so that the magnets are aligned with the stator. The blades are made of 4 inch PVC.You can find templates online for the blades.Put the outline of the blades from the paper onto the PVC and then cut it out with a jigsaw. And then once you cut it out with a jigsaw, all you have to do is get a little Sander out, you can use a hand Sander to smooth the edges off. Connect the blades to the faceplate of the old ceiling fan. Next step is to take an inch galvanised pipe that forms the body of the turbine. A 40 inch piece will slide down into the conduit of the mounting system for your turbine.A 30 inch piece on the back,This is going to be angled up into the wind to keep the blades in the wind a little better. One Inch PVC is slid down the end of the 30 inch pipe and attach the tail piece on there which is made of fan blade The wires from the fan is passed through the pipe and just zip tie them down.Cut the PVC in half to a 45 degree elbow ,cut a line down through this PVC, we're gonna split it basically and drill some holes in it and attach the ceiling fan blade. Attach the fan to the galvanized pipe with the help of an extension that was previously saved during our dismantling of the ceiling fan.Use JB weld on the inside of that. And I put this bolt through this part and put a tightening screw on it, they're kind of digs into the metal. Connect the two leads from the fan to a bell wire, solder these two together, wrap it up with some electrical tape and kind of zip tie to the top so that it will stay in place.At the base end of the wire,connect it with a diode bridge rectifier which is further connected to our battery. Regarding connecting the rectifier,it doesnt matter how you solder them together,just as long as they are separate and not connecting and shorting out. But you want to put this at the base of the wire at the very end so that you can put this inside of your battery box and hook it up to your battery. https://www.youtube.com/watch?v=sr9ZMbF3Zqk&list=PL68TKRSLgXzQqZa5WzMNFwmYKS4b4KPcA
    • How to build a Simple Alternative Power Dual Refrigeration System that uses no electricity
      This project goes over the conversion of an old three way refrigerator unit from an RV into an alternative power offgrid Dual refrigeration system that uses no electric power. This can be really useful in case of a power outage or SHTF situation when you need to keep your food or vegetables fresh. The first step is to strip the fittings on the back side of the fridge , remove all the ammonia system ,clean the inside of it . Here we are incorporating more than one way to use this water for cooling refrigeration system to make it efficient .We will be using cooling effect by brining down the water temperature to cool the box , another way to cool the box is by installing an evaporative system. We take the two pipes coming from the water source around the edges of the box and put some cotton sheets around the sides and let the water cascade down the sheet creating an evaporative effect. We have an inverter and a battery attached to the fridge that is hooked up to a 25W solar panel .The wire from the inverter is connected to 8W Electric Fish tank pump .The water coming from the pump goes underneath and up inside to the lid of the fridge to the condenser coils and then comes back around back into the water source like well or water tank. The full system is recirculated back into the original storage tank where the water is coming from. We keep the fridge in a chest freezer style instead of an upright style. Inside the fridge, we have incorporated 2 poly tubing coils attached to an old heat sink that was already in the fridge. The 100ft coils are attached to the top of the fridge. The cold from that coils will drop down to the rest of the fridge. Next step is to incorporate the evaporative cooling part of the refrigeration system. We start by installing aluminum U channels across all the edges of the fridge. The U channel will hold cotton material inside of them. The water coming out of the outputs from our coils rushes into the channel which is going to wick out into the cloth and run down the cloth with gravity, giving us our evaporative cooling effect . On the corners, we have the U channels interconnected to each other through a bent garden hose in such a way that any extra water flow in the channel can transfer to the the channel that is next. The cotton sheets are stretched around the box and tuck it down into the channels all the way around under the wires such that the wires will hold the channels up and hold the sheet up inside the channel. To even the flow of the water ,we install a tee. Now the water coming from both sides of the channel can leak into the sheet. Also make sure you have an air gap between the sheet and the refrigerator box. https://www.youtube.com/watch?v=mHspLgLWJug
