Spec addendum: what the second review found and what was done. One build, one answer (the law changed: PRESS only adds, a hole lets the same through whatever is outside it, the top of the water is a link like any other), what it costs, every sweep run again, and what is left (#30)
Spec addendum: what the second review found and what was done: loose blocks pay for water, fluid runs through a pulley hook, tied ropes, and part-wound rope that goes with its load (#21)
Falling water is drawn as a stream as wide as there is water, never as a full cell: a trickle looks like a trickle, and moving water is never drawn as more water than there is (#20)
A water wheel with water falling straight through keeps turning one way when the motor on its shaft is fed by a generator on a second shaft: any motor with a generator's current in it only slows a turning wheel (#18)
