Abstract:
A solar powered device for aerating a body of water having a depth comprising:at least one solar power source being electrically connected to at least one battery being electrically connected to at least one air compressor, said air compressor having a range of maximum efficiency; at least one diffuser that is pneumatically connected to said air compressor, said diffuser being mounted in said body of water at said depth and providing a backpressure at said depth of said body of water to said air compressor such that said backpressure enables said air compressor to operate within said range of maximum efficiency and enables said diffuser to produce a substantially laminar water column, said diffuser having a plurality of holes spaced at a predetermined spacing and sufficiently small so as to minimize coalescing of bubbles produced at said depth by said diffuser; said device being adapted to produce said substantially a laminar water column.
