1. A tilt-driven pump for elevating a fluid, the tilt-driven pump comprising:
a plurality of tiered inner central fluid basins stacked proximal to a central axis of the pump;
a plurality of tiered peripheral fluid basins stacked distal to the central axis;
a plurality of radially inwardly elevating fluid ramps; and
a plurality of radially outwardly elevating fluid ramps;
wherein each peripheral fluid basin is fluidly connected to a plurality of radially inwardly elevating fluid ramps circumferentially spaced about the central axis, each of said radially inwardly elevating fluid ramp configured to transmit fluid from said peripheral fluid basin to a more highly elevated inner central fluid basin; and
wherein each inner central fluid basin is fluidly connected to a plurality of radially outwardly elevating fluid ramps circumferentially spaced about the central axis, each said radially outwardly elevating fluid ramp configured to transmit fluid from said inner central fluid basin to a more highly elevated peripheral fluid basin.
