This video shows the build of a Emergency Water Distillation Portable Still that removes biological, salt and heavy metal contamination from drinking water.The still is made by putting an upside-down stainless steel funnel over a pot of boiling water as a lid. Ideally the pot is designed for cooking, but in an emergency any metal container, such as a soda can, may be used. Connect a 1/2 inch diameter copper pipe to the funnel with three 45 degree elbow fittings. Put a damp rag on the pipe to condense the steam. Fresh, drinkable water will drip out of end of the pipe
- How to build a Simple and Efficient Homemade Garage Fan out of Old Furnace BlowersThis video shows the build of a Homemade Garage fan made out of Old Furnace blowers that is easy to make and really efficient.Once you try one of these you'll never use a box fan again. These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out. If you want to be scientific you can look at the side of the motor and read the rated amps. Then with a load meter hooked up, run it and block off the air flow until the amp draw drops to or close to the rated amps.Centrifugal fans are amazing at moving a large quantity of air and the output can be ducted unlike axial.
- How to build a Simple Homemade Water Distiller that turns dirty water/salt water into clean fresh pure water[the_ad id="6432"] This video shows the build of a "pure water" Water Distiller that easily turns dirty water/salt water etc... into clean fresh pure water. This produces lots of clean water fast. Made from close to 12 feet of copper tubing along with a few fittings (optional stainless steel tube shown as well). video contains full instructions on how to build it. Early testing shows it produces about a quart in 1.5 hrs (and half gallon in 2.5 hrs). note that i soldered on the copper fitting. If you don't have a torch, they sell "push on" fittings that require no soldering. *if soldering, remember to use "lead-free" solder.The process is simple. It boils water and creates steam. The steam rises without bringing any of the impurities along with it. The steam travels through the coils and slowly cools and condenses. It finally condenses back to its liquid form and drips out as clean water.
- How to build a really powerful Solar Powered BullDozer that requires no fuel.Step by step Build InstructionsThis video series shows the step by step build of an awesome 275 Watt Solar Powered BullDozer from start to finish.The Solar panels are connected to 4 golf cart batteries that powers a 1 and half HP motor,which again are connected to a bunch of gears and sprockets that independently power each of the 4 wheels to get the maximum traction.Even with 10% power,this bulldozer works like a champ.Another feature of this dozer is easy to control manual steering mechanism.The body is build out of Aluminium/Stainless Steel.The cool thing about this bulldozer is that it runs without Gasoline.Yep no gas needed .ever!!
