Richard, that is really neat. I have heard of such a contraption before.
What I wonder, given that it operates while driving (hot shower when you
arrive at camp, right?), what keeps the water from sloshing in the pot,
even over topping as it sloshes? After all, anything in motion, tends to
stay in motion until an arresting force stops it. Any acceleration or
deceleration would tend to cause sloshing, it seems to me. Or is the pot
sealed, thus keeping the water from over topping the pot?
