Here's a pic of Pete with Norbu, putting the plexiglas up. He emailed me the next day with detailed statistics on silica as a desiccant. I wanted to share these stories with all of you, to give you an idea of how much devotion each of those you see on these pages brings to the project. Pete, the chemical engineer, has helped us work out logistics in a way we never could have without him (waaaay back in the beginning he worked out the estimated flow rate of our power washer so we could calculate how much water we'd need to use it!). Thanks Pete!
