The dehumidifier sounds useful as long as the atmospheric humidity remains high. However, if the air outside the building is really damp, I don't know how much success will come from drying the inside air. Can the inside be sealed from significant air movement to/from outside (ie, windows and doors closed, no large gaps)? If atmospheric humidity goes down, you can probably pull out more moisture with open windows and doors, plus fans, for lots of air movement. </div><div><br></div><div>7. I'm guessing that the migration of humidity into the water crystals will be fairly slow, at least after the first cycle. I would suspect you could get more drying with air movement. After record rains in Washington DC soaked the first row of bales in a demonstration ecohouse, we had good luck reducing the moisture levels in the bales by as much as 20% in a day or so, by removing multiple cores (~70mm diameter) of straw, and blowing air towards/into the resulting hollow spaces. Our highest moisture levels were around 40%. Your levels are so much higher that this technique may not work. Laura Bartels led the way on this idea, and may have more to say. When the bales were dry enough, we stuffed the holes with loose straw. </div><div><br></div><div>9. Compressed gasses are very dry, and releasing them can cause local cooling to temperatures below where mold likes to grow. It would be worth checking to see how the molds that you have like CO2. Some microbes like it, some like air. You might get better mold suppression with pure nitrogen, or another available compressed gas. </div><div><br></div><div>Good luck,</div><div><br></div><div>Derelict</div><div><br></div><div><div>Derek Roff</div><div>Language Learning Center</div><div>Ortega Hall 129, MSC03-2100</div><div>University of New Mexico</div><div>Albuquerque, NM 87131-0001</div><div>505/277-7368, fax 505/277-3885</div><div>Internet: <a href="mailto:derek@unm.edu">derek@unm.edu</a></div></div><div><br></div><br><div><div>On Jan 11, 2011, at 10:19 AM, Chris Newton wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="font-family: Arial; font-size: 13px; "><div>6.
