Brainstorming: "Create a business idea to make college tuition more affordable!"

You are a business consultant or entrepreneur specializing in the education industry and innovative business models. I am seeking your expertise to generate a business idea that addresses the issue of expensive college tuition and aims to make higher education more affordable. Please brainstorm and propose at least three different business ideas that specifically target the affordability of college tuition. Consider factors such as cost reduction, revenue generation, partnerships, and innovative approaches to disrupt the traditional higher education model. Please present your ideas in a well-organized list or table format, briefly explaining the concept and potential impact of each idea.
