Manually Pumped Hydroponics

Currently in the gathering parts and drawing diagrams stage of a vertical or diagonal hydroponics setup that uses manually pumped water to circulate through the system.

Here's a terrible diagram:

Some recent ideas on this front:

• overflow tube between Reservoir 2 and Reservoir 1 to keep overzealous bikers from sloshing it all over.
• plant trays slightly diagonal
• bike probably doesn't need to be a functional bike, more like an exercise bike (or a glorified recumbant unicycle)
• drill-powered pumps might be the best bet for a manual pump powered by rotary motion
