Looks like the project has been getting some attention lately, more by others than by me... I've been busy with this insane FPGA contract project as well as job hunting/job finding/prepping to move to the new job 2300 miles away. I probably won't have the best environment in Arizona to test the condensation mitigation/monitoring I had planned.

It did get me thinking about a solar-powered "water from air" device to see how much water could be extracted from dry air on a 250W solar power budget. A couple of years ago I worked briefly on an experimental, industrial-sized WFA meant to solve logistics problems in Iraq. Dessicants and heating/cooling loop could produce several gallons of water per gallon of fuel, an advantage for locations where liquid water didn't exist and the fewer truck trips the better. Wouldn't ZERO gallons of fuel be perfect? I keep thinking of projects I don't have the time to complete.
