As with Lunar Ventures:
the competition focuses on developing viable space-related business plans for technologies that have real-world potential. The 8th Continent Project Business Plan Competition challenges students in business, engineering and science to collaborate in creating business ventures related to space, but with immediate application on Earth. Teams should consist primarily of graduate students, although undergraduate participation is welcome. Prizes for the winner include up to $50,000 in cash and in-kind services.
