In my Defense tier, I would really like to have .45 Camp Carbine with an integral suppressor and mounted thermal imaging. If I spent my resources on that and only had a CB radio and a 72 hour kit as my only other preps, then I would not be spending my resources wisely.
It is most cost effective to buy a year supply of food using the LDS list before you spend twice as much on a 3 month supply of freeze dried food.
Water Purification is Important
That being said, you might have noticed I am on a water purification kick. Some of that is that I have noticed the amount of water I have been using on livestock and gardening. Some is that I realize its impossible to store water for an extended period due to space and weight issues. The third reason is that I ended a preparedness tier with my Calcium hypochlorite prep. One small purchase game me the ability to disinfect approx 50k gallons of water. It is easiest to start the next tier on water since that’s what I have been researching lately.
What is a Chlorine Generator
Today’s project is a device used to create a practically inexhaustible supply water purification chemicals. Basically, it make the same disinfecting solution as the calcium hypochlorite makes. You might ask why I went through the trouble of buying the HTH pool shock if I had planned all along to make a device that does the same thing. Especially considering the storage considerations of the corrosive chemical. Well, the pool shock is does not need an energy input to work. I cannot break it. Additionally, I bought a lifetime supply for under $25.00.
The DIY Chlorine Generator for Water Purification is also called a Chlorine Producing Unit (CPU) I am about to show you works very well, but it requires 12 volt electric input, uses expensive and technologically advanced electrodes and cost a little over twice as much to make.
I have found that American missionaries that work in the third world are an excellent supply of information in what some call “appropriate technology” This is people centered, small scale, labor intensive, energy efficient, environmentally sound devices and processed. It’s a lot like “Macgyverisms” from my favorite 80’s TV show. He had advanced knowledge and primitive supplies and was able to cobble together 1900’s level tech with modern scientific principles.
One famous example of this is the CD3WD which is a collection of appropriate tech, Travis Hughley and barrelponics (which I AM going to build one day) and Safe Water International Ministries the developers of the CPU that is the focus of today’s article.
SWIM has developed the CPU to provide a chlorinating solution for water disinfection in third world countries. I would highly recommend you check out their website and consider donating to their mission as they are doing wonderful work.
Comes in a Complete Kit Also
If you want a CPU, but don’t have a DIY gene or interest in building one yourself, SWIM sells complete CPU tool box kit which includes an instruction card, a chlorine test kit, 2 mixing bottles, a salt measuring cup, and a couple of solution droppers. All you need to provide is 12 volts of electricity, salt, and water. A donation of $150 to their ministry would support this kit.
I wanted to turn this into a project so I gave a $50 donation and received the anode and cathode from them. They will email you the plans for free if you contact them on the website, and they have a technology link online with the instruction manual and a basic lesson plan for teaching this to others. I will warn you, the cathode and anodes are the main expense in the CPU, and you may have a hard time finding a supplier. One is a titanium mesh; the other is a mixed metal oxide (ruthenium).
However, I must tell you that their primary mission is to provide these units for missionary work in third world countries, so if demand causes a supply backlog, I would imagine they would fill that need first.
Basically what happens is when you bridge the electrodes with a salt water solution and apply an electrical charge to them you start a chemical reaction called electrolysis. In this particular process the water bubbles and produces a caustic chlorine solution roughly half as strong as laundry bleach. After the 9/11 attacks many municipal water treatment plants converted to this process so that they could remove their one ton chlorine gas tanks from their sites to mitigate their attractiveness as a terrorist target.
Per the SWIM for Him website the directions for use are:
- Mix salt & water solution ( approx. ¼ cup salt to 16 oz water)
- Connect wires to 12 volt source (negative, or black, to negative; positive, or red, to positive)
- Pour the saltwater solution through the CPU into another bottle (observe the bubbling process)
- Carefully repeat the pour-through process 5 times.
- This is different from a chlorate cell as that the water free flows through the unit which does not allow chlorates or perchlorates to form. This process operates at a different voltage and a much lower temperature.
- Unhook the battery wires.
- Rinse the CPU by pouring clean water through it.
- Add 10 drops of the solution for each gallon of drinking water.
- Wait one hour before drinking.
It works with Solar Also
Additionally, if you are using solar power to charge your battery, you will want to recharge it for 3-5 hours after this process to ensure it is fully charged.
You will also need a test kit to ensure you use enough chlorine solution to properly sanitize your water supply.
This was a very simple project and I built the device in under an hour, I have to wait about 24 hours for the sealant to set, and then another 30 minutes in finishing touches. Please watch the video below to see all the steps.
Today we are going to talk about dehydrated hamburger. This is commonly called
We all know that nothing is free, especially food storage, finding foods that are cost effective, and long storing generally means you have less of the two V’s – Variety and Vitamins. Sprouting wheat and weans is a way to add both. I used to associate sprouts with homeopathic medicine practitioners, vegans, and yuppie soccer moms, but once I got over my initial prejudice I have learned that it’s simple and cheap to add sprouts to my food tool-box.
