A little searching and memory jogging shows that those fold-out solar panels for Duos were made by Keep It Simple Systems of Helena, Montana. They were bought by PowerQwest (which I think is Advanced Power Technologies) in 1999. They still sell a line of notebook solar power supplies at http://www.powerexperts.com/ , though I think the models have been renamed (and presumably refined). They used to use Unisolar amorphous panels, but now seem to use the more efficient (and more expensive) Kyocera crystalline ones. You could probably talk to them about your project, anyway. I chatted via email with one of the KISS principals a few years back and found him friendly. -- Marc Sira | [EMAIL PROTECTED] "If you can't play with words, what good are they?" ---------- Duo/2400 List, The friendliest place on the Net!
