Savage was talking about doing this in equatorial ocean waters,
with his preferred first site being in the Indian Ocean between
the Seychelles and Zanzibar (because later, he wants to build a
laser-launcher in Kilimanjaro). That has open access to cold
flows from the Antarctic waters.

There might be a way to package or preprocess the discarded algae
(more specifically, the carbon, which would be the only thing we'd
really be trying to get rid of) so that it decays anaerobically,
or goes into the sediment layer without withdrawing or releasing
any constituents to or from the abyssal waters.
