Dr TLUD - Gasifier cook stove A comprehensive examination of TLUD technology will necessarily involve four essential realms or areas of focus: Fuels Combustion Devices Applications of Heat Human Factors Every successful cookstove project must address four essential components: fuels as the source of energy for producing heat, combustion devices (devices to release the energy of fuels as heat and light) to obtain heat, applications of produced heat (i.e., the purposeful capture of heat energy, as in a cooking pot), and human factors such as costs, cooking preferences/traditions, cultural considerations, and user-friendliness. Failure in any of these four components will lead to failure in the project. Many cookstove projects are differentiated primarily by applications and human factors.

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. Sandia Labs investigates new offshore wind turbine designs Albuquerque-based Sandia National Laboratories is conducting comprehensive research into the viability of vertical axis wind turbines (VAWTs) for offshore use. The design, previously considered impractical for large-scale applications, has the potential to transform offshore wind technology, making it a more economically viable energy source. The research is being conducted under a 2011 Department of Energy (DOE) solicitation for advanced rotor technologies for wind power generation in the United States. The US$4.1 million research project began in January of this year and will continue for five years. The first stage will last two years, during which time, several concept designs will be created and run through modern modelling software.
Build A Gasifier - Gasifier-Kits Is building a gasifier too difficult? Well you could just buy a kit or a small scale designed unit. The links here explore a range of options. Announcing the New v.5 GEK Gasifier & Power Pallet - GEK Gasifier Now with 24hr run time, increased reliability and ease of use Today we’re pleased to announce the new v5.0 GEK Gasifier and related Power Pallet. Two years in development, the v5.0 represents a generational change in our core gasifier technology, incorporating all we’ve learned over the last five years of development and deployment. For you, this means a significant advancement in performance, ease of use, and cost of operation/maintenance. GEK Wiki / Run an Engine with the GEK return to How to Build and Run the GEK Gasifier How to do wood gas conversions for gasoline, diesel, and propane/natural gas engines with the GEK Gasifier. Have you welded and painted and properly assembled the GEK Gasifier? Have you fired up the flare and adjusted the results until you get a clean gas? If so, you've graduated to the next level: run an engine with the GEK to start making power. Below are the instructions and suggestions you will need to get started.
Earthtubing for sustainable, passive geothermal heating & cooling Earthtubes (earthtubing) are a most highly recommended low-tech, sustainable, non-electric, zero-energy, geothermal passive solar heating and solar cooling system. Earthtubing utilizes conventional, thin wall plastic sewer drain vent pipe to passively pre-heat your home's fresh air intake with zero-energy consumption. Filtered fresh air enters a series of non-porous pipes embedded around the interior of your home's foundation, absorbing energy from the surrounding soil, moderating the temperature of fresh air intake. When done correctly, air drafts naturally through your earthtubes for a truly sustainable, non-electric, zero-energy, passive geothermal system that perfectly supplements a high thermal mass HTM home's back-up heating and cooling system. Please be careful with earth tube details though... while 'Green architects' are warming to the idea, they are making very elementary mistakes, such as using large diameter concrete culvert pipe for their earth tube air inlet pipes.

10-20kw Power Pallets - GEK Gasifier Why it’s different The Power Pallet is the culmination of our long-standing project to create an expertly engineered, small-scale gasification solution that is realistic for today’s user. While personal scale gasification has long held tremendous promise, the realities of making it work usually prove too much for regular mortals. The high bar of operator expertise and extreme sensitivity to fuel particulars, usually combine to make what seems simple in principle, exceedingly difficult in practice. The Power Pallet has significantly widened this window for success by embedding the needed “expertise” in an onboard electronic brain.
Absorption refrigerator An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar, kerosene-fueled flame, waste heat from factories or district heating systems) to provide the energy needed to drive the cooling system. In the early years of the twentieth century, the vapor absorption cycle using water-ammonia systems was popular and widely used, but after the development of the vapor compression cycle it lost much of its importance because of its low coefficient of performance (about one fifth of that of the vapor compression cycle). Nowadays, the vapor absorption cycle is used only where waste heat is available or where heat is derived from solar collectors. Absorption refrigerators are a popular alternative to regular compressor refrigerators where electricity is unreliable, costly, or unavailable, where noise from the compressor is problematic, or where surplus heat is available (e.g., from turbine exhausts or industrial processes, or from solar plants).
