Crypto? <geek>A little rot13 in the water never hurt anybody, and most
healthy adults can stand up to 5% Enigma.  But if there's any PGP at all

At 2 amps, it might not be totally insane to bring the power from the
van.  If you used a 16 gauge 30' extension cord (about equal to 1.25
mm^2, 10 m), you'd lose about a quarter of a volt each way - the voltage
at the pump would be 0.5 V lower than the voltage at the van.  The cord
_probably_ weighs less than the extra battery, too.

Yow!  I looked up some other brands of UV sterilizers and they are all
pretty insanely priced, for what is basically a $10 fluorescent light
fixture with a metal pipe over it.  Maybe getting the pipe sealed to the
lamp is tricky or something.  (The other usual explanation for pricing
like this is that most of it is for lawyer food, which is not improbable
for something that is meant to be used to make water "safe".)
