This Video shows the build of a Solar Evacuated Thermal Vacuum Water Pump works by harnessing the energy of the sun in the day time and then uses the cold of night to create a vacuum in the system that is used to pump water. This is a working prototype of an idea on how to pump water from stagnant water sources cheaply using no moving part.By using the sun’s energy to generate both a pressure and a vacuum cycle we create a very efficient water pump, that has only two simple moving parts. This pump was able to move one gallon every cycle to 8 feet high, by creating artificial day/night cycles the pump could move about 1 gallon every 30 minutes of sunlight, or about 12 to 20 gallons a day.
- 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.
