Modern concept: Water columns are they `effective'?

Today, it is quite common to see `artificial' tubes containing water.
The base of these tubes produce bubbles and lighted up usually with blue light.
As most of the water is enclosed, only a small surface i.e. the top of the tubes are in contact with air.
One has to suspect whether, beneficial Qi flows better or less under this tube. Contrast this to more traditional concepts like a water wall or a fountain.
Some homes are begining to use the smaller versions of it. Perhaps, could the lighting in the water tube or the bubbles create benefical Qi even if it is not exposed to air? Well, we need to evaluate them further.
