Well documented is the attempt at creating a giant
floating ice maker to create a pycrete aircraft carrier
Problem is that it's energy intensive.
I propose a propose a nuclear powered giant (solid
state magneto) refirgerator that is created to make
of a durable type (pycrete
Also this island can be repurposed as worlds
biggest penguin refuge, with turrets that
automatically shoot seals and walruses to ensure
penguins are safe. I like penguins.
Floating island is generally kept parked in coldest
possible waters sufficiently far from pack ice for it
As waves continuously break apart floating ice city,
more ice is made, and all sky facing surfaces of the
ice city are painted with high albedo paint, or simply
covered with sufficient amounts of reflective ice.
Internal city heat is provided by waste heat of
nuclear reactor and is well insulated to prevent ice
melt below and above.
I'm thinking this makes sense in the waters between
south Africa and Terra del fuego
bonus points for a technology that harvests ambient algea
and seaweed as a fibrous resource for creating the pykrete
as opposed to having to ship it in from land.
