No photos for this - couldn't figure out a way to make it look interesting...
Ever since he heard about them in engineering class, Paul has wanted to build a hydraulic ram pump; it took buying this lot to make constructing one feasible. So, he took a break from building his wall, bought a bunch of PVC pipe and fittings and built a system to move water from the Tisingal Rio up the bank so we could use the 'fortified water' (don't forget there's a trout farm uphill from us ;-) for our plants.
Basically the thing works on a mathematical formula comprising length of accumulator pipe, and drop. Gravity is its ONLY means of propulsion (that or magic). Whatever, every ten seconds, it's pumping a gallon of fishy water straight up the bank. The plants are thrilled.
