Home-made Hydraulic Ram Pump

Home-made Hydraulic Ram Pump
Home-made Hydraulic Ram Pump This information is provided as a service to those wanting to build their own hydraulic ram pump. The data from our experiences with one of these home-made hydraulic ram pumps is listed in Table 4 near the bottom of this document. The typical cost of fittings for an 1-1/4" pump is currently $120.00 to $240.00 (U.S.A.) depending on source prices, regardless of whether galvanized or PVC fittings are used. Click here to see a picture of an assembled ram pump Table 1. All connectors between the fittings are threaded pipe nipples - usually 2" in length or shorter. Conversion Note: 1" (1 inch) = 2.54 cm; 1 PSI (pound/square inch) = 6.895 KPa or 0.06895 bar; 1 gallon per minute = 3.78 liter per minute.

Assembly Notes: Operation: The pump will require some back pressure to begin working.

How to Make an AC Arc Welder Using Parts from an Old Microwave, Part 1 In a previous article, I demonstrated an Arc Welder made using parts from old microwave ovens. Here is part 1 of 2 on how that arc welding machine was made, and how you could make one too! This is the first of two parts on building it, focusing on the modification of the transformers. WARNING: Stick welding, and/or the modification of a Microwave Oven Transformer (M.O.T), can be very dangerous and presents risks of UV radiation, shock hazards, burns, fires, fumes and a multitude of other risks. This project should not be attempted without a thorough understanding of electricity, adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury and/or death.

Living Off-Grid: Our Micro Hydro Alternative Energy System Blue Energy Published on March 24th, 2009 | by Jennifer Lance As a follow up to Sean’s post on Micro Hydro Essentials, I thought I would share an overview of my system, which has powered my home for over 13 years. How to Naturally Clean Indoor Air Turns out that indoor air can often contain more toxins and chemicals than outdoor air. Everything from mattresses to pots/pans to kids PJs can contain harmful chemicals in indoor air. It’s best to reduce chemical exposure in any way possible, but in today’s chemical laden world, it is practically impossible to completely avoid harmful toxins. For the remaining chemicals in indoor air, there are some natural ways to help reduce your family’s exposure. I’ve mentioned houseplants before and they are a great option for improving indoor air (read my full list of recommended plants here).

Fabricating a Heavy-Duty Rocket Stove Rocket stoves are small efficient stoves that can produce a hot flame with only a few small pieces of wood. The reason it is called a rocket stove is because when wood is added to the fire the flames create an internal draft. As the draft is created, the fire begins to produce a jet of fire coming through the stove pipe. Making a simple Savonius wind turbine by Lance Turner There are many situations where you might need a small amount of electricity, for instance running gate openers, safety lights, water level indicators and other low-power devices. While solar would seem like the ideal solution, quite often this is not possible due to location and shading problems. Cheap/Free Window Insulation Bubble glazing Whenever financial aspects take precedence - availability of resources seems to be a disincentive for progress in sustainability and conservation. When we can afford more – we simply waste more, without even admitting for consideration that Earth is a system of limited resources.

Tesla Technology: 5 Bladeless Turbines About to Revolutionize Energy Production “Every home in America can run on wind energy. In fact these units can be installed on existing power poles in rural areas, to catch the wind and send its energy back to the plant.”- Raymond Green, Inventor In 1913, Inventor Nikola Tesla patented a bladeless steam turbine that he claimed was the most efficient and the most simple rotary engine ever designed. Due to a lack of high-quality materials, Tesla was never able to properly build his engine. One century later, we now have all the materials needed to build Tesla’s turbine, and in 2010, a patent was issued to a company called Solar Aero for a wind turbine based on the Tesla design. BubbleWrap Window Insulation Search The Renewable Energy site for Do-It-Yourselfers Installation Cut the bubble wrap to the size of the window pane with scissors. Spray a film of water on the window using a spray bottle. Apply the bubble wrap while the window is still wet and press it into place.

people Perpetual Futility A short history of the search for perpetual motion. by Donald E. Simanek Popular histories too often present perpetual motion machines as "freaks and curiosities" of engineering without telling us just how they were understood at the time. They also fail to inform us that even in the earliest history of science and engineering, many persons were able to see the futility and folly of attempts to achieve perpetual motion.

Strategic smart plants It's easy to think of plants as passive features of their environments, doing as the land prescribes, serving as a backdrop to the bustling animal kingdom. But what if the ecosystems of the world take their various forms because plant "decisions" make them that way? A new theory presented by Princeton University researchers in the journal Nature Plants suggests that in some cases that may be exactly what happens. In one of the first global theories of land-biome evolution, the researchers write that plants may actively behave in ways that not only benefit themselves but also determine the productivity and composition of their environs.

DIY Super Efficient Chest Fridge Hack Chest fridge Using vertical doors in refrigeration devices is an act against the Nature of Cold Air. Understanding and cooperating with Nature rather than acting against it leads to much better efficiency. My chest fridge (Vestfrost freezer turned into a fridge) consumes about 0.1 kWh a day. Hydroelectric Hydroelectric Power - Water power - micro hydro systems Micro hydro power is probably the least common of the three readily used renewable energy sources, but it has the potential to produce the most power, more reliably than solar or wind power if you have the right site. This means having access to a river or creek that has a high enough flow to produce useable power for a good part of the year. Many creeks and rivers are permanent, ie, they never dry up, and these are the most suitable for micro-hydro power production. A micro hydro turbine can take several forms, the most widely recognized of which would be the water wheel, used extensively for grain grinding up until this century. Waterwheels are still used in some situations that do not require a fast-spinning turbine, such as for pumping water.

5 DIY Earth-Friendly Cooking Devices Capturing HEAT Five Earth-Friendly Cooking Technologies and How to Build Them The Cabin Stove - A Small Masonry Heater at Aprovecho Research Center » Firespeaking A good part of the month of August has been dedicated to the research, development and construction of a small multi-functional masonry heater I have been calling “The Cabin Stove”. Eva and I have both been working as instructors in the first year of the Sustainable Shelter Workshop Series at Aprovecho Research Center in Cottage Grove, OR. The building that is the focal point for this course has been designed to be just slightly smaller than the legal requirements for permitting so that it can at the same time be a teaching tool as well as a laboratory for a basic building system that a group of associated natural builders in the Pacific Northwest considers to be a sound and ecological way of making a home.
