More on artificail icebergs
Wondered if Pycrete might be a choice for creating, or sustaining, floating icebergs. It doesn’t melt rapidly and might actually be able to be made as the winter months approach the arctic. I’m thinking we might be able to “seed” the water in a contained area with the required amount of sawdust or wood pulp (even unprinted newspaper).
You wouldn’t need to tow anything since you’d be making it right there where its’ needed. Obviously treated wood couldn’t be used but there should be ample supplies of sawdust from mills up north. The trick would be to try and keep the mixture contained so that it would refreeze correctly.
Pycrete was the material that was looked at during WWII for possibly building float iceberg/aircraft carriers for the North Atlantic.
