Ed Richards and others at the CCCC say you should use a trawling battery that's designed for slow and deep discharge. You might also look into nickle iron and other batteries.
There seems to be a lot of low power hardware around now. I've heard good things about the Slug and older Lynksis access points. If I was really going to be without power for a month, I was going to drop down to my Zaurus. Googling turns up some more modern and capable hardware: http://www.linuxdevices.com/news/NS5010953811.html http://www.linuxdevices.com/news/NS5320707472.html http://www.linuxdevices.com/news/NS8479495970.html http://technocrat.net/d/2008/9/3/48704 The OLPC was made for situations like this. It has a nice pull generator and lasts for ten hours. On Thursday 11 September 2008, Edmund Cramp wrote: > Right Will. I'd like to get rid of the UPS all together.
