The Holey Roket technology promotes using biomass briquettes and their hole as the key feature of an efficient cooking system. The flames coming in the combustion chamber are condensed within a small space providing higher heat output and therefore better combustion of toxic gasses like Carbon Monoxide (CO).
The project was conceived as part of the Masters of Applied Arts degree in Design at Emily Carr University in Vancouver, BC in Canada in collaboration with Legacy Foundation (biomass briquettes technology) and Aprovecho research center (cooking-stoves technology). The project has won the Governor General Gold Medal Award for academic achievement.
