A team of international judges have selected a shortlist of fifteen entries to go through to the final of the James Dyson Award.
Over 500 projects from 18 countries have been whittled down to the top 15, which includes a design by 22-year-old Victoria University industrial design graduate, James McNab of Tauranga.
Mr McNab designed the Revival Vest for free fall divers.
It uses smart fabric technology to monitor respiration and changes to the body which can occur during drowning. Once it detects a change, Revival Vest automatically inflates to bring the user to the surface and to safety.
The successful entries will now be reviewed by James Dyson and his senior engineers. The winner will be revealed on 8th November.
Full details of each project can be seen at the James Dyson Award website
