[TheForge] OT: Spring tile question

Tue Apr 3 00:28:37 EDT 2012

Jerry,
It is amazing what you know. I am not planning on doing this at this time. I 
would prefer to excavate land that would allow water to come out at surface 
under its own pressure to avoid contamination issues per Paul,s note.
Do you know of a video or other reference to this method? I tried looking it 
up on the net a few years ago and I did not find anything except for a 
reference to a windlass  of which I am not familiar. I am just interested in 
the physics.
Thanks!
