Will Broadway's "Isobar" has been designed to keep vaccines at the ideal temperature while in transit in developing countries. And Will doesn't plan to make money from his creation. His focus is to get it to people who need it, which is why he won't be trying to get a patent. "I make things every day for people who have everything," Will, an industrial design and technology graduate from Loughborough University, tells Newsbeat. "I wanted to make something for people who have next to nothing. It should be a basic human right, in my opinion, to have a vaccination. "I don't think that it should be patented to restrict use." Will's Isobar has won him the annual James Dyson Award, open to students across the world with a simple brief - design something that solves a problem. Current methods of transporting vaccines can result in the vaccines freezing before reaching their destination in countries where poverty and conflict are major obstacles. The device maintains a steady two to eight degrees for 30 days. It works by heating ammonia and water to create ammonia vapours, which are then released into its main chamber when cooling is needed. Will was inspired to start work on a portable refrigeration unit in 2012 when he visited Cambodia and parts of south east Asia. "These trips sparked an interest," he says. "It pushed me. Something needs to be solved for this major issue."
