Hi Robin
I am glad you realise me for what I am. My dog thinks I'm pretty smart too, but only when I am near the fridge.
Yes, I can make water run uphill. came up with this thing that ? I call it a siphon. Having some difficulties with the patent office though. I your case, tell your client the solution is easy; just mount the reservoir on an elevator. No natural laws broken and no messy pumps. Not sure about the cost though.
Cheers
Steve

Steve,
Your a Genius.
I have this gravity pipeline that conveys water to a reservoir and the client has asked that he would like the water to run both ways. I said that I new of a bloke that could probably make water run up hills with out pumping!
Cheers,
Robin
