A tool designed to clean hard to reach areas in semi-automatic rifles and pistols, a cloud-based platform to deliver high quality virtual reality content via the Internet, and a high-tech, sanitary product dispenser. These are just three of the ideas Virginia Tech student teams recently presented while vying for their share of $30,000 in prize money in the VT KnowledgeWorks Global Entrepreneurship Challenge Semifinals.
