I definitely did not want to give you angst.

You didn't. I just was not able to understand what you were referring to.

I wanted to inspire some critical thinking

Perhaps my English failed me, but my questions were aiming at the same target :)

By the way, it looks like I was off by 8 feet.

I am afraid you were completely off - capillary effect work on completely different principle. You are referring to the pressure, while in the capillary veins wetting is a driving force pulling the liquid up.

It would be interesting to see capillary action move water 1000 feet (or 10000). Somehow I would think that would be amazing.

http://en.wikipedia.org/wiki/Capillary_action

Looks like for 1000 feet (304.8 m) you will need something like 9.2*10-8 m diameter glass capillary - thin, but sounds possible (and it can probably accomodate enough water particles across so that they will still behave like water, not some quantum liquid) :)

The main problem I see is the speed at which water will travel up. It will be very slow process, with the friction all the way up slowing it more and more...
