I’m not sure of the intended location of Project Habakkuk, but year round ice in the north is just thick ice. A conventional boundary for annual vs. year round ice is 3-4 m thickness: https://en.wikipedia.org/wiki/Polar_ice_packs I think a first experiment would be to see if one could make an

Excuse a slightly off topic reply, but isn't a problem with some sea ice creation projects that they attempt to freeze salt water on top of the ice ? Sea ice naturally forms at the bottom of ice, and the ice formed is (I understand) less salty than the sea. This can't happen with top freezing tech

While sawdust worked as an insulator in block houses, those conditions were in the dark. In the real world, ice made from that would presumably be less reflective and so absorb more solar during the sunlit hours. Would it not make more sense to figure out how to make a lot of tiny bubbles to be tak

Based on experience with making ice islands as drilling platforms, one can make ice by spraying water into the air. On already formed ice one need not spend the energy on spraying (formation of a mist is energy intensive); rather just pump water on to the surface. In my mind this would be the objec
