That's great,I'm curious to see how much of the primary survival group we can cover with. Example-fire,shelter,signal,water,food,medical,etc.. (Iknow you can't eat it for food but mabey power a laser pointer to coral fish in a trap (I use to use the laser pointer to run the fish around the pond at night for kicks). The one thing I have noticed is that 20 watt cells seam to be the starting point of effectively utilizing the sun. A 5 watt cell can take days over what a 20 Watt or greater can do in hours.
