A pump, a PWM controller, digital timer and the Li-ion 12 volt battery and great things can happen.

Yeah, I was thinking along those lines once too. The crops I was considering were clandestine rhubarb and wild berries up in a (wet and cool) microclimate in a tiny valley in the sierras with a stream running through. I got the crops planted, and then the drought hit, the stream dried up and they all died. That location would be perfect for weed, too though!

Were I to get a really crappy MB (like that 700k mile one in austin) I'd definitely try the cheap pump, and just keep an eye on the coolant level. The plastics it is built with are pretty chemically and thermally stable. On another sidenote, I've got the old pump from my 300D laying around, maybe a new motor can be sourced to cheaply rebuild them.
