As many of our readers know, Off Grid Pro was born in the backyard of Troy Martz, with the vision of building alternative energy devices, with an early emphasis on gasification technology. We are very proud of what we were able to achieve, but—for many reasons—have decided to change directions… Read More
Method of Calculation: A Cord is defined as a tightly stacked pile of wood with the following dimensions: 4′ x 4′ x 8′. This volume (128 cubic feet) contains an average of 85 cubic feet of wood and 43 cubic feet of air. Each pound of wood contains 8660 BTU’s, but with well-seasoned firewood at 20% moisture, only 6200 BTU’s are available… Read More
In a recent proposal, the Off Grid Pro team crunched some numbers and created an infographic, outlining one potential energy model, using non-woody biomass as the material. In this particular case, a horse farmer has a need to handle 3.5 tons of horse manure each day. Additionally, he averages 150kW / day in electrical usage. This model illustrates how that manure can be pelletized and pyrolyzed into gasifier fuel.
Troy Martz from Off Grid Pro discusses appropriate alternative energy technologies based on biome, climate, and context. This interview was conducted prior to his talk at the Permaculture Voices Conference (PV2) in San Diego this year, entitled, Alternative Power for Permaculturists… Read More
