Vertical and Free Standing

In this prototype iteration I want to incorporate the use of some extraordinary materials. I know that this design could take advantage of energy generation because of the water free fall that occurs as the plants are being irrigated. I have consider light or a fan that could be implemented. My goal here is to achieve a functional prototype that can illustrate areas of difficulty when the assemblage is complete. Currently I am facing issues of leakage and proper seals, I am also facing issues with the amount of pressure that irrigation requires for a sprinkler system that feeds more than one unit. I want to incorporate a fan(propeller) that can take advantage of the falling water going back to the reservoir, hence generating energy for another processes in the unit. I've tough of adding a high power LED lighting system that could connect to a rechargeable battery that is connected to the fan. Or maybe just generating a breeze through the fan that can aid in cooling the plants in hot weather.

Things I need right now(ASAP):

I need a fan that can be exposed to water and humidity and that can work to generate energy. I also need a more efficient irrigation system than the puncturing of hydroponic line. The little holes only seem to work temporarily, they close up as the plastic retracts, or the pressure from the pump can't accommodate all the exits. (Perhaps a more powerful pump?) I will test...
I also need to further test the frame in which the irrigation unit sits and the advantages of making the frame adjustable or maybe mobile through pivot points in an axis as to allow vertical and rotational motion.
