The company it was through makes solar chargers for those going where electricity isn't easy to come by, they are http://www.voltaicsystems.com/.
We were in need of a solar kit to aid in the charging of our cameras and Iphone, and after a brief phone call with Jeff at Voltaic Systems, we had the perfect set up, consisting of 2 x 3.4 Watt solar panels going into a V39 battery. The panels will be on "extension cords" so we can move them around the canoe and the battery will stay in a dry bag, as we don't want it to get wet. Voltaic is also including the cradles needed for our two separate cameras.
This was a huge moral booster. We now don't need to worry about keeping our electronic devices charged, just have to keep them dry, which may be difficult out on the ole' Miss.
Here is a link to my information they posted on their blog, check it out, http://voltaicsystems.
