This video shows the build of a DIY solar powered, pressurized, roof top water heater and shower.This is done using an ABS 4 inch pipe, 6 feet long, which would give me a capacity of 15 Litres or 4 US gallons.This is an easy and inexpensive project that required minimal tools and just some basic plumbing parts.I started by installing the shutoff valve. I wanted the drain to be as low as possible in the pipe to avoid necessity of having to tilt the system. To ensure the valve retaining nut did not interfere with the pipe once it is glued into the, I positioned the nut away from the wall of the cap using a bolt, which is the same thickness as the wall of the pipe.I drilled out a 2” threaded cap and tapped in a radiator valve drain plug that I picked up at the local automotive parts store. This valve will allow me to release pressure from the tank should that be necessary without opening the drain shutoff. Also when open, this will allow a gravity fed system through the drain valve should for some reason I not have access to the air compressor.As a final step to improve thermal absorption of solar energy, I painted the surface with flat black paint. First I lightly buffed all the ABS surfaces with steel wool soaked Methol Hydrate. Then applied one coat of spray primer followed by two coats of flat black paint.

- How to build a Simple Homemade OFF GRID Refrigerator from easily available materialsThis video shows the build of an OFF GRID Refrigerator from cheap and easy to find materials.This design uses both the cooling effect of evaporation, and two water cooled condenser coil's. The fridge is shown using both a water ram pump at the end, and an electric pump powered by 12 volt/solar, it only uses 8 watts an hour using electric.There is an air gap between the sheet and the wall of the fridge because the water running down the sheet wont evaporate as well and that the water temp is not as low as the evaporative temp so the water touching the cooler could increase the temps and limit some of the potential cooling. If the power goes out and the fridge doesn’t keep things cool anymore – what other options do we have? If you are trying to live off grid and have no power source – how can you keep food and certain medicines cool and usable for longer?Then this Offgrid Refrigerator is the answer.
