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 Powerful Solar Powered Homemade Air Conditioner. Blows cool air for hours.This video shows the build of a Homemade Powerful ice-based air cooler that can hold large ice-blocks (up to 50lbs) and blows cool air for hours.This can be powered by 12v solar panel, 12v battery or wall current (w/ 12v ac/dc transformer).This is made using a plastic tote, 2 lighted 80mm 12v computer case fans (blue-lit/but choose your color) and 3 pvc couplers (1.5" threaded).Tote is from walmart, fans from fry's electronics/amazon and pvc couplers from home depot/lowes. When fully loaded w/ice it significantly cools an area of 8x10 to 10x10 for several hours.The fans can be easily removed/or exchanged, (any 80mm fan works so you can run different colored ones, unlighted ones, ones of different speeds etc...anytime you want)
