I know these are very generalized questions, but they intrigue me so: the types of nonelectric pumps out there. The five main types I know of are:
Pulser Pumps
Rife River Pumps
Ram Pumps
Gravity Pumps
Water Wheel Pumps
What other nonelectric pumps do you all know exist, and what situations do you all think each one is best suited for? Which ones do you all prefer and why? What additional uses could each pump have, like water oxygenation, etc?
