[Mesh] power requirements

Hi folks, I've been lurking on this project for a long time and alot of the networking stuff is frankly over my head at this point. I do however want to help out with deploying some solar powered or at least solar/battery backup nodes. From the wiki I read 8 watts at 12-24V. From talking to Marc I also understand the logic level of some of the devices is 3.3v. Using a 30W panel and an 8AH battery I bet we could have a station up most of the time. I'm ordering some batteries that size for various projects, and the big 235W solar panel that was/is in the backyard of adeline livelabs is free to be cut up for this purpose if still around. Here is the best price I've found in the area http://sfbay.craigslist.org/eby/mat/4282816517.html and I'd be willing to split a case of 70W panels 50/50 with the mesh project and maybe a few others depending on how much interest there is in having them solar powered. Anyway, looking forward to seeing the network grow bigger and more resilient. Cheers, Hol
