Dear list members: I am wondering if it is possible to use the kinetic energy of a heat engine to run a dehumidification compressor for kiln drying lumber. Even better, is it feasible to use the pressure differentials directly to pump refrigerant? The recovered heat could preheat the lumber charge, and later in the drying schedule makeup vented moisture. Just dreaming, David Strom The Gasification List is sponsored by USDOE BioPower Program http://www.eren.doe.gov/biopower/ and PRM Energy Systems http://www.prmenergy.com Other Sponsors, Archives and Information http://www.nrel.gov/bioam/ http://www.crest.org/renewables/gasification-list-archive http://solstice.crest.org/renewables/biomass-info/gasref.shtml http://www.crest.org/renewables/biomass-info/ http://www.crest.org/renewables/biomass-info/carbon.shtml
