How does ice make money?

Could you please elaborate on the mechanisms by which ice generates revenue? I'm curious to understand the various ways in which ice can be monetized, whether it's through direct sales, indirect methods, or perhaps even more innovative strategies. Could you provide some examples or scenarios where ice has been effectively used as a source of income? Additionally, I'm interested in knowing if there are any specific industries or applications where ice plays a pivotal role in generating profits. Thank you for your insights on this topic.
