This video shows the step by step build of a Double Burner Rocket Stove made from an Old Ammo Can.The can is around 19″ x 10″ x 10″, I use vermiculite as insulation, some use sand instead but I like vermic as it is fairly light.If you remove some of the insulation and it’ll be a mini barrel stove for heating too.Here i use a Black and Decker Scorpion saw to cut the pipes and just a cheap bi-metal hole saw to do the holes. I’ve cooked a full steak dinner in the woods on it and it worked great.
- How to build an Inexpensive Geothermal Solar Air Conditioning System to Cool your Garage using an Old Car Radiator ,Solar Panel.This project goes over the build of a cheap Geothermal Solar air conditioner that can cool your home with the Earths natural cool temperature. A few feet underground, the temperature remains between 55 and 60 degrees Fahrenheit. This is true regardless of the weather above ground.The geothermal unit siphons heat from inside and vents it into the water or refrigerant in the loop. The cool temperature underground then lowers the temperature of the liquid back to 55 degrees. In my case when I draw the water well, the static water level is 2 feet above the ground and and what that means that there is a free flowing well that runs down the hill. This is connected to a 55 gallon drum buried in the ground to keep it cool. A circulator pump is used to pump the water to the radiator. The water well is about 85 feet.We drop a 10 foot pipe in there and get a cheap pump from a car and probably some check valves valves and maybe start a natural siphon and run out of solar. You will need an old car radiator for this project. The Radiator used here is from an old Volvo Car. This is used to circulate air using a solar panel. The water coming in is connected to the radiator and the water coming out the is attached to a PVC drain pipe . The radiator is hooked to a motor connected to a solar panel. A Temperature sensor is attached to the radiator fan to detect the indoor temperature. The pump is out of the same Volvo car from which I got the radiator. A Coolant temperature sensor can be added to measure the temperature difference from the inlet versus the outlet and just see how much heat get pulled into the water . The system works on Solar.You will need a Charge controller,DC to DC Convertor and 12 or 24V batteries. https://www.youtube.com/watch?v=sOxnJ5DceeU&list=PLpZKoEWMZEz_OeTiV3mx47jy1jOUL6yqe
- DIY Video : How to build a Survival Water Distillation System for under $5 and turn Salt Water Into Fresh WaterThis project goes into the build a simple survival water distillation system to turn your salt water into drinkable fresh water. This setup can be made with little more than two glass bottles, some metal trays and some sand. So the primary components of this setup are two glass bottles, the wider the bottles are in diameter ,the better and a pair of metal trays. The first part of this process will be to prepare an area such that the two bottles can rest mouth to mouth. The important part is that one of them needs to be suspended over a heat source. This could be done over an open campfire, you just need to find a way to suspend the bottle above the flame either using rocks or logs. Cut a small notch on one side of the pan so that the neck of the bottles can sit a little lower in the pan. This is by no means necessary, but it will make the setup a little more secure. With the trays secured in place, both of them are now filled with sand. The sand will allow the trays to more efficiently act as heat sinks, one tray to cool one of the bottles and the other tray will be used to very evenly heat the other bottle so that it doesn't shatter from being heated too much on one side. The bottle is pressed firmly into the sand so that it gets good thermal contact and will be heated evenly. The second bottle is adjusted such that its mouth will meet up with the first and it is also pressed into the sand to obtain good thermal contact. Another reason that I'm using sand for this is because it makes it very easy to adjust the bottles angles and it is best to make the bottles meet up as evenly as possible so that there is not much room for water vapor to escape. We want it all to make it into this second bottle where it can condense as freshwater. As an additional measure to keep the cold half of the bottle cold, we wet the sand on this bottle with water or cover them with a wet cloth to allow evaporative cooling to take place. With such a large quantity of sand in this tray it does take a little while for it to reach the boiling point and get this process started. But once the sand has reached that point, it stays hot for a long time. So it is a pretty quick process as the water boils dry in this first bottle to simply refill it and you can continue on with the distillation process as long as you want. Rotate the bottle so that the top portion becomes hot from the steam, it is rotated into the cold sand below. And in that way the entire bottle maintains a cold temperature which causes the distillation to go much faster. https://www.youtube.com/watch?v=R_-wFiFdwAE
- How to build a Simple Backyard Bio Sand Water Filtration System from easily available materials .This project goes over the build of an emergency cheap bio sand water filtration system. This can filter out your polluted water from your stream or lake or gutter. Bio sand filters are good for filtering parasites, bacteria, protozoa virus and fine sediments from well water. These work by doing four stages of purification. First is the biological zone where bacteria eats your parasites and pathogens viruses. That happens on the surface of the bio zone. The second is mechanical trapping where sediment can be attracted to porous rock, and it will filter out sediment absorption, third one is absorption where the electrostatic charge which will attract small particles and viruses down to virus level and get attracted to this sand and last stage is natural death from nutrient depletion when there won't be anything for bacteria or virus to eat or thrive on when they start to go through the sand dairy of the filter. There is two five gallon buckets, one stacked on top of the other. These are black food storage buckets. These buckets don't tend to promote the growth of algae as much as the opaque buckets do. The top bucket is the water storage bucket, the top one is the filter. There is an eighth inch hole on the lid at the top bucket that allows water to flow freely without creating a vacuum. There is a 16th of an inch hole at the bottom of the bucket that slowly let the water drip out onto the top of the next bucket. The bottom bucket has 8 one quarter inch holes along the sides. This allows the water to disperse over the top ,they drip down to the these holes along the side of the bucket such that they dont disturb the biozone underneath. It'll take about three weeks to establish a bio zone. And during that three week period, you're going to have to continually feed some polluted water in there with bacteria in it to feed the bio zone to make it develop and grow. It would put a large circular ring in the center of your bio filter and distribute the bacteria off to the side. Now this filter relies upon bacteria that forms on the top of the sand to eat the other bacteria like Giardia and Cryptosporidium. A pipe at the center will prevent the sand from coming up into the faucet and getting into the drinking water. We here have two layers of sand. The bio zone is going to have a couple inches of fine sand on it to promote the growth of the bacteria. The course sand underneath will filter out sediment and other bacteria. Bottom layer is an inch of fine and pea gravel. The second stage of this filter starts with the build of a 4 way distribution pipe made of PVC pipes and a four way coupler. We cut holes in these pipe ,one towards the end and the other towards the center. This will distribute the water over the top of the bucket and so that the water isn't just going in in one spot and trickling down one side or down the center and not evenly distributing it over the top of the sand Drill a hole at the bottom of the 2nd bucket and put a quarter inch brass drain plug .This can be used to drain water out the barrels if I want to store them or to flush them out. We put put 3 levels of gravel and 3 levels of sand in the second stage. Put two to three inches of each layer of gravel. Add an inch of activated carbon on top of this fine gravel. Treat both the filter with chlorinated water and fresh water and let it sit for few minutes. Stack the second stage filter on top of the first stage. Make sure the whole setup is tightly sealed. Further purify the water by letting it sit under the sun. The ultraviolet ray purify the remaining bacteria that might be in there. https://www.youtube.com/watch?v=6bqYI1Z68jM
