“Dad's oil dehydrator was a contained electrostatic field, one electrode down the center, the other the container's inner wall. Principal problem was finding a dielectric to separate the two. Refuse oil poured in came out as oil of the highest grade, dry chemicals, and drinking water. Petroleum Rectifying Company successfully prohibited its use.” — John Cage
