TROMPE - Powered Passive Aeration of Mine Water Thursday December 12, 2013 (Revision of video posted Tuesday, June 18, 2013) PITTSBURGH, PA — In the 1600s, Italian engineers discovered a way to compress air using only gravity and water. Later on, Spanish engineers working on ways to improve iron production, realized this technique could be used to drive their tools. In the 20th century, modern engineers realized the advantages of using the same device to drive tools used in underground mining while also supplying fresh air to miners. Variable Speed Blowers are built for optimal service life., AMETEK Technical Indust Designed for Gas-Fired Burner Systems: Nautilair® 7.6" (192mm) variable speed blowers for gas-fired burner systems incorporate brushless DC motors to enable reliable performance in excess of 20,000 hours with minimal maintenance. These pre-mix burner blowers are designed to deliver a measured air/fuel mixture to optimize combustion and reduce nitrous oxide and carbon monoxide emissions. Applications include commercial and residential boilers, water heaters, furnaces, foodservice equipment, kilns, and fuel cells, among others.
Bottle Hydroponic Systems | Hydroponics Equipment | Hydroponic Gardening Supplies & Systems Bottle Hydroponics Systems You must have come across many guidelines on the Internet regarding simple methods of building homemade hydroponic systems, but not all of them are really cost effective and efficient. The three main factors that you should consider while building a hydroponics systems are: cost, complexity of building the system and the system’s efficiency.
GEK Wiki / How to Build and Run the GEK Gasifier GEK Licensing Fabrication, Assembly, and Operating Manuals Below you will find all instructions for fabricating, assembling and running the GEK gasifier and Power Pallet. The instructions support a variety of paths-- from complete DIY wood gas plans for scrap tank hacks, to assembling and firing the various complete gasifier kits offered by ALL Power Labs. 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.

About $17 million of the solar funding is available only to DOE national laboratories.
La bioponie, quelques informations - Comment ça pousse ? Le guide de la culture hydroponique La culture bioponique : hydroponie biologique Depuis des années, des recherches intensives sont entreprises par les chercheurs d’un grand nombre de pays pour trouver un moyen de faire de l’hydroponie réellement biologique. C’est enfin William Texier qui, en 2004, a découvert et mis en oeuvre le concept de la culture bioponique, la nouvelle méthode de culture hydroponique biologique.

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. The challenge of the design of the Cabin Stove was to come up with something that was very compact but also still resembled and functioned like a masonry heater.
A Rocket Stove Made From a Five Gallon Metal Bucket The principle behind a rocket stove is simple–rather than cooking on an open fire, you burn wood in an insulated chimney. Rocket stoves are highly efficient and easy to make. They run on twigs, so you can avoid cutting down a whole tree just to cook dinner.
Pulse Output WattNode AC Electric Power and Energy Meter The WattNode Pulse is a true RMS AC watt-hour transducer with pulse output (solid state relay closure) proportional to kWh consumed. The WattNode provides accurate measurement at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. The complete Pulse Output family measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations. With voltage ratings from 120 to 600 Vac and current transformer (CT) ratings from 5 to 6000 amps, there is a WattNode combination to meet your AC power measurement requirements. Diagnostic LEDs
