For the first stages of prototyping I have decided to make two designs out of bulk aluminium cans to test how the different designs affect the way the fire reacts.
• Test one – This design concept needed much less fuel as there was less surface area for the fuel to over.
• This design concept of a larger can for the outside and a smaller can for the inside where the fire was light. The idea behind this concept was 1, to see how the fire reacted and worked and 2, to minimize the heat of the outer can, this is to minizine the risk of burns while the fire it alight. The outside can only reached a high of 107 degrees.
• This meant the fuel kept at a steady temperature for a longer period. The fire was able to keep water at a steady temp of 82 degrees for 6 minutes
• This model was able to keep the water at a consisted temp while using a minimal amount of fuel.
