 On a related note - Would it be possible.
 
 My local airport is, literally, 1 mile from my house.  But there are no
 hangars and no electricity anywhere near the tiedowns.  The closest airport
 with hangars is 40 minutes away.  I'd like to rig up a battery - something I
 can carry in my car - to hook up to something like this the night before I
 fly.  That way, when I arrive in the winter AM, the darn thing isn't 25
 degrees.
 
 I was thinking the smallest, cheapest, lightest, system.
 
 Any thoughts?  Would a 35lb battery keep it warm all night?  If I used a
 deep cycle battery would I be able to charge it numerous times without
 killing the battery?
 
 Thanks,

 Matt
