ETHOS 2007, Seattle, Washington, USA Jan 26-28, 2007

Crispin Pemberton-Pigott, Larry Winiarski and Charlie Sellers Test Tom Reed's Woodgas Stove with a Combustion Analyzer.

ETHOS 2007 in Seattle was a stimulating and inspiring event. Many thanks to the ETHOS executive committe for organizing it and to the 120 attendees, some who dragged stoves on airplanes to the event. There were many high points during three (for some four) days of meetings which I am sure will be discussed in these forums and on the web for weeks to come. To list a few:

Computing Moisture Content of Wood, Woodbin, Woodworking Software. http://www.woodbin.com

The moisture content of wood is directly related to the humidity and temperature of the surrounding air. The equilibrium moisture content (EMC) occurs when the wood has reached an equilibrium with its environment and is no longer gaining or losing moisture. Here is a calculator for computing the EMC of wood at or below the fiber saturation point (about 30% moisture content) given the temperature and relative humidity.
