hey
i was bulding one of my idea's that includes wicks to transport water up against gravity.i tried different materials like paper towels and some thin pipes.Water soaks the material very fast and i can get it go like 4-5 cm above the water surface and relatively big volumes of water in this coffie cup experiment (up to 5ml per sec).Has anyone an idea how to make water leave the wick on top?

I imagined it will just drip off to another cup and from there new wick will transport it next few cm up the hill etc. creating the cascade of the wicks i wanted to transport the water to the Kelvin generator main bucket to close the cycle.

Any idea?

The wick effect stops when the water reaches the top
wick then drip

on top of this, there is a maximum height by which that effect ceases to exist.  Perhaps you could incorporate the coanda effect, burnullie effect - like apparatus to expedite the flow at the end. some sort of ball bearing or..

I don't know what I mean by that, btw.  But, picture an sweet-pea like pod, an expansion at the end of the wick, facing in the opposite direction where the wicking is coming from, like towards gravity.  the expansion would create a low pressure area.

Hi,

Perhaps if you let the upper end of the wick bend down say 5 - 7 mm (depending on its thickness), would look like the letter  J  but of course upside down.  Important thing is what you use for fixing the bend: it cannot be water-absorbing and probably should touch the wick the less area the better.
This way water could drop from the wick's ending by gravitation I think.

well i want this drip,but it just does not happen

@all
Thx for advices,i will experiment on it.

What are you wicking with?

maybe a tube such as one would find from a standard phone cable, just pull the copper out of one of the individual strand and you'll have a nice sleeve.  insert some smaller diameter fishing line in the copper's place and it might work as a wick.  the problem with any wicking setup is that it will get clogged easily and stop working, it's also vapor dependent.  now, if your working some sort of evaporator system, then if it's closed, alcohol may be a good one to work with.  you may not have to insert the fishing line all the way down, just far enough that it reaches around the "J" bend and sticks out the end.
