- A member proposed using an Energy Recovery Ventilator (ERV) to isolate calcium chloride (CaCl) dehumidification inside a space, noting the same setup could be extended to achieve sub-ambient cooling rather than just humidity control.  
- A link to the 15-minute YouTube talk “Open Source Inverter State of Art” was shared, covering current progress on open-hardware power inverters.  
- The Open Source Ecology wiki page for Tim Schmidt (https://wiki.opensourceecology.org/wiki/Tim_Schmidt) was posted as background on the inverter project.  
- A market data point was offered: used 250 W solar panels are available for ~US $50, translating to roughly US $0.20 per watt for small-scale solar procurement.
