has conducted 21 ocean tests of various sizes and depths
of our wave-driven pumps. We have progressed from 10” diameter
to 44” diameter and from 200â€™ depth to over 1,000â€™ depth.
With each pump diameter, and at each depth, we have measured
temperatures at the bottom and top of the pump, and we
consistently see cold deep water reach the top of the
pump. We also have
installed a motion sensor on the valve to track opening
and closing which corresponds to wave periods. Shown
some data from these tests.
addition, we now are outfitting our buoys with satellite telemetry,
GPS, and ocean sensors so we
can follow our drifting pumps drifting
with the currents. Pictured here is the path of a recent deployment
off the Western US. The pump is following the California current
southbound at roughly 2 kmh.
now offer tube and tubeless models of pumps which can be tailored
to produce application-appropriate
upwelling. Either design can
be inverted to generate downwelling, useful in combatting anoxic
conditions and “dead zones”. And we now offer a model
suited for low-wave conditions.
