[Paddlewise] question

I am following the discussion about that race closely. Some of the
expeditions  I am participating in require a rescue insurance.  Perhaps
that should be done,  require someone who organizes a high-risk race like
this, to buy an insurance or require the participants to have one!
Now here is my question: Did you read the Seakayaker magazine from December
2003?  There were instructions to build a solar battery charger for the
kayak deck.  I am a pphysics teacher in a pre-engineering High School
Program.  I would like to do this activity as a project in class. The
materials are forbidding expensive.  So I had the idea,  perhaps some here
at the list would be interested to have one of these solar-battery-chargers
build.  It would be for the materials, shippng and a nice lunch for the
kids (11th and 12th graders). I hope, it is not against the rules to ask
this question here on the list! If,  then I apologize.  Otherwise,  if you
are interested,  please contact me back channel!
