Okay, thanks again Springer for sharing your project and ideas. Since the thread is relatively dead please do not take this as a hijack. I have adapted your idea and this a project I am currently working on. It is basically a old Shell Gas station pump I stripped down and one old water cooler designed for a 5 liter reservoir (pictured in the Styrofoam). I installed a new ballast for the light since I could not run the 347v ones installed (top of pump). One side of the panels are currently being primed and then painted with a metallic blue auto paint. Glycol is on order.
I am sure by now you have all figured out where this project is heading. I intend to make it glycol cool lines via fish pump with a new reservoir and keep the kegs external for ease of swapping. I will add a timer to start about an hour hour before my leisure time until completion for conservation purposes. I do indeed have the hoses for it but will be installing standard faucets and possibly a drip tray on the top portion instead.
