This 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.
- DIY Video:How to build a simple Off Grid Electricity Generation System using Two BatteriesThis project shows you how to generate Off grid AC Power using a simple Solar power station with 2 batteries.This system can provide enough off the grid power to run your appliances around the house.You can easily run light,a laptop computer, small tv and fan for several hours. Most of the item required can be bought from your local store or Amazon.The rough cost of building this system is as follows : $150 for 100W Solar Panel $75 each for 2 batteries. $20 for 400w Inverter $40 for charge controller. The whole system comprises of four things, a couple of batteries, inverter, and a charge controller.The inverter is purchased from Harbor freight ,the charge controller from fry electronics.The deep cycle batteries are from Walmart. So you start by setting up your panels outside. In this case, I have six one amp panel set up, 15 watts a panel, so that's 90 watts coming in. I lead them straight down to the main connection, it's just the six black wires all connected together and twisted tightly to that extension cord wire and the six red ones connected.Feed the line into your house,goes straight to the charge controller. The output wire from the charge controller goes into the battery.So solar panels to charge controller ,charge controller to lead battery in your bank.And as you want to expand this to two,three or more batteries, just use some automotive cables and go from positive terminal of one the positive of the other. And with a black wire, negative terminal to negative terminal, the other one. When you want to run something, just get your inverter that converts the power from DC to AC, take the clamps, clamp them onto that same lead battery in the system. So again, red to the positive side, black to the negative side and flip it on. So remember, when you hook things up like an inverter, or the charge controller or voltmeter, anything you're going to hook up on here, make sure you always pick one of the batteries to be the lead battery and hook everything to that. Whether you parallel one extra battery with it, or five or six or however many you want to put on there. Also added here is a lighted voltmeter which gives you a constant reading on your battery bank so you know exactly what's going on with it at all time. https://www.youtube.com/watch?v=cgEvCLJuBkg https://www.youtube.com/watch?v=8LAjx_XAR90 A simple system that can come really handy during a power outage or in any emergency situation.

- How to build a Large 2000W Portable Solar Power Generator at Home from scratch.The idea of a completely silent power generator that can still run large power loads, and never need gasoline is a really cool concept. This project goes over the build of a large 2000W Portable Solar Generator that can power appliances ranging from a table saw to charging your phone effortlessly. We need a large box to hold our basic components. Here we use a pelican 1620 protector case that is durable, dustproof and waterproof .This is going to be the case that we package everything into. It's got wheels on the bottom so you can roll it around ,also has heavy handles on either sides. The battery is a AGM glass mat ,coil would style, 12V optima deep cycle battery. A deep cycle battery just allows you to get a little bit deeper into the discharge before you are starting to shorten the life of that battery. This battery also has the ability to be mounted in any orientation . So it is safe whether the battery is on its side on its back or even upside down as long as we have it mounted securely so that nothing shorts against our terminals. The next major components for our build is the 2000W inverter from Krieger. This one has some large terminals on the back for our wiring. Also has a active fan here for ventilation. Also comes with a remote control switch. The 100W Solar Panel is from Renogy. It has the bus on the back for connecting in to your solar charger .It also comes with a 30A Solar Charge controller. This can run up to four of the 100 watt panels in a 12 volt system. The back of the solar panel comes pre wired with MC4 connectors, as well as a couple of MC4 pigtails. We use high quality 16 gauge speaker wire to extend the connection. These wires are highly flexible for portable use. To connect it to the MC4 pigtails we need to go ahead and strip the insulation off and use butt splice connectors to crimp them to the MC4 pigtails. In case you cant to charge the system with standard AC power ,we use a 1.5A Battery maintainer / Float or Trickle charger. This will be good for just keeping it topped off when it is in storage. Or if you just want to charge up your batteries and you really don't have a place to be setting the panels out. Next step is mounting components on the outside of the case . Before mounting any component, factor in how the internal components are going to placed inside the case. On one side of the case ,we are going to mount a small LED work lamp with toggle switch, a 12V gauge pod with 5V USB output, digital voltmeter,12V cigarette socket ,an AC input plug for using with the trickle charger, a 6pin solar panel trailer connector. These components are secured in place using a RTV silicone sealant. One the other side of the case , we are going to mount the inverter remote control switch, 350A high current plug which is used for jumper cables or to add high current loads, a GFCI AC outlet with a weatherproof cover. The GFCI outlet is connected to the inverter inside the case. We want to put the battery as close to the wheels as possible, because that will help keep the heaviest part down low when moving the case around either on the wheels or by carrying it. We place it snug into a corner of the case using battery mount and couple of pieces of 2X4. The inverter is placed inside the case in such a way that there is enough space for air ventilation and for tucking some of the wires underneath. The inverters are secured in place using mounting tabs and 10x24 machine screws. The PWM solar charge controller is also mounted in the same way near the solar panel connector input. The trickle charger / battery maintainer is placed as low into the back of the case .This is not something that will get very warm so we don't need to worry about heat dissipation or anything like that . We plug the power cord from the trickle charger into the AC input cord. Next step is the wiring. We start by connecting the power cables from the inverter to the battery. The positive and negative from the inverter is connected to the positive and negative of the battery respectively. To distribute power in our generator ,we use a six circuit fuse panel for the positives and a busbar for the grounds. We use two inexpensive battery cables to run the power to our distribution blocks as well as running the power to our high current quick connector. The positive red connection from the quick connector goes to the fuse panel and the black negative connector to the ground busbar. Both connections are further extended to connect to the positives and negatives of the battery respectively. The LED lights are connected to the 3 way connector switches. The switches are further connected to the power distribution fuse block. Similarly a single switch is connected to the USB outlet, voltmeter and the cigarette lighter ports in parallel. The positive from the switch is connected through a daisy chain mechanism to the three positives of the ports ,the negatives are similarly connected to our distribution block. At this point, we now have a power wire and a ground wire for every single one of our accessories connections . We bundle these wires and keep it neat and tidy using zip ties. Separate the positive wires from the negative wires, we are going to be rounding the negative wires to our ground busbar. After we have all of the ground wires connected, we can move on to the power wires on our distribution block. Each one of the blade connectors represents one fuse circuit. We connect the positive red wires from charge controller, battery trickle charger, usb ports,voltmeter,12V outlet to the fuse circuit. We are using a 30A fuse for the charge controller,12V socket, 20A for the LED work lights, 5A for the trickle charger. https://www.youtube.com/playlist?list=PLIorqrLdxMKZV464fFUflegLuuvLEyMrU
