This year we outgrew our Google group, and established a website for evapotrons. The name's pretty easy to remember:
www.evapotrons.info It's pretty easy to mistype, too, so watch out for these:
evapotrons, not evapatrons and not evapotron
.info, not .com
There's another name that also works:
http://sites.google.com/site/evapotronsThere are more evapotrons than just the Gray-B-Gon. Our website collects evapotron history, and covers the "Pumped Cascade", which works well and beat the Gray-B-Gon to the playa by a year or so. The site also offers instructions for building a Gray-B-Gon, and guidance for leading a construction workshop. We hope you enjoy browsing.
